5G Remote Surgery and Telehealth Solutions


One of the most controversial 5G use cases is the remote surgery. In this post I want to quickly look at the history and what is possible. Before I go to that, here is a short summary video that I am embedding upfront.



As far as I can recall, Ericsson was the first vendor that started talking about remote surgery. This is a tweet from back in 2017.


Huawei didn't want to be far behind so they did one at MWC Shanghai in 2018. Their tweet with video is embedded below.


In January 2019, South China Morning Post (SCMP) showed a video of a remote surgery on an animal. While the video and the article didn't provide many details, I am assuming this was done by Huawei as detailed here. The video of the surgery below.



This was followed by Mobile World Congress 2019 demo where a doctor used 5G to direct surgery live from a stage at MWC to Hospital Clinic Barcelona over 3 miles away. The team of doctors was removing a cancerous tumor from a patient's colon. This video from that is embedded below.



Vodafone New Zealand had a silly remote surgery of a dog video but looks like they have removed it.  Nothing can beat this Telecom Italia ad embedded below.



There are some realistic use cases. One of them being that with 5G the number of cables / wires in a hospital can be reduced saving on the disinfection.
NTT Docomo showcased 5G Mobile SCOT (Smart Cyber Operating Theater) which is an Innovative solution to enable advanced medical treatment in diverse environments. You can read more details here.

There are lots of other things going on. Here is a short list:
  • April 2020: Because of Coronavirus COVID-19, NT Times has an article on Telemedicine Arrives in the U.K.: ‘10 Years of Change in One Week’ - even though this does not involve 5G, it just shows that we are moving in that direction.
  • February 2020: 5G-aided remote CT scans used to diagnose COVID-19 patients in China (link)
  • February 2020: Verizon teamed with Emory Healthcare to test new 5G use cases for the medical industry at the latter’s Innovation Hub in Atlanta, in a bid to discover how the technology can be used to improve patient care. The collaboration will explore applications including connected ambulances; remote physical therapy; medical imaging; and use of AR and VR for training. (link)
  • February 2020: Vodafone 5G Healthcare – Conference & Experience Day (link)
  • November 2019: TIM enables first live remote-surgery consultation using 5G immersive reality (link)
  • October 2019: Along with a hospital in Malaga, Telef√≥nica has presented what it claims is the first expert assistance system for medical interventions that runs on 5G. (link and video)
  • September 2019: Mobile Future Forward 2019 - World's First Remote VR Surgery Demo conducted on Sept 4th, 2019 in Seattle by Chetan Sharma, James Youngquist, Evie Powell, Nissim Hadar, David Colmenares, and Gabe Jones. (link)

Real-life 5G Use Cases for Verticals from China

GSMA have recently published a series of reports related to China. This includes the 'The Mobile Economy China' report as well as reports on ‘Impacts of mmWave 5G in China’, ‘5G use cases for verticals China 2020’ and ‘Powered by SA case studies’. They are all available here.

China currently has 1.65bn subscribers (Excluding licensed cellular IoT) which is expected to grow to 1.73bn in 2025. The report quotes 1.20bn unique mobile subscribers that is expected to grow to 1.26bn by 2025. With a population of 1.44 billion, this would be assuming everyone over 10 years has a smartphone. 2G and 3G is being phased out so only 4G and 5G will be around in 2025. This would be different for IoT.

The 5G Use Cases for Verticals China 2020 report is comprised of 15 outstanding examples of 5G-empowered applications for verticals, ranging from industrial manufacturing, transportation, electric power, healthcare, education, to content creation, and zooms into the practical scenarios, technical features, and development opportunities for the next generation technology. Every use case represents the relentless efforts of 5G pioneers who are open, cooperative, and innovative.

  1. Flexible Smart Manufacturing with 5G Edge Computing (RoboTechnik, China Mobile, Ericsson)
  2. 5G Smart Campus in Haier Tianjin Washing Machine Factory (China Mobile, Haier)
  3. Aircraft Surface Inspection with 5G and 8K at Commercial Aircraft Corporation of China (Comac, China Unicom, Huawei)
  4. Xinfengming Group’s Smart Factory Based on MEC Technology (Xinfengming, China Mobile, ZTE)
  5. SANY Heavy Industry 5G and Smart Manufacturing (Sany, China Mobile, China Telecom, ZTE)
  6. Xiangtan Iron & Steel's 5G Smart Plant (Xisc, China Mobile, Huawei)
  7. The Tianjin 5G Smart Port (Tianjin, China Unicom, ZTE, Trunk)
  8. 5G Intelligent Connected Vehicle Pilot in Wuhan (China Mobile, Huawei, et al.)
  9. 5G BRT Connected Vehicle-Infrastructure Cooperative System (China Unicom, DTmobile, et al.)
  10. 5G for Smart Grid (China Mobile, Huawei, et al.)
  11. Migu's "Quick Gaming" Platform (China Mobile, et al.)
  12. 5G Cloud VR Demonstration Zone in Honggutan, Nanchang, Jiangxi Province (Besttone, China Telecom, Huawei)
  13. 5G Cloud VR Education Application Based on AI QoE (China Telecom, Nokia, et al.)

NB-IoT based smart bicycle lock


Huawei (see here and here) has partnered with China Telecom and Bike sharing company called Ofo.

ofo developed an IoT smart lock based on NB-IoT technology that lowers power consumption, enables wide coverage, and slashes system resource delays at low cost. NB-IoT lets ofo ensure it has bikes located at key locations when commuter demand is highest. Meanwhile, bikes can be unlocked in less than a second. Both improvements have greatly boosted user satisfaction.

ofo and its partners added key technologies to ofo’s own platform. These included the commercial network provided by China Telecom, and Huawei’s intelligent chip-based NB-IoT solution. When launching its NB-IoT solution earlier this year, ofo founder and CEO Dai Wei said that the cooperation between ofo, Huawei, and China Telecom is a “mutually beneficial joint force of three global leading enterprises.”

At the core is Huawei’s IoT solution, which includes smart chips, networking, and an IoT platform. The solution provides strong coverage in poor-signal areas and a network capacity that’s more than one hundred times stronger than standard terminals. The payment process has dropped from 25 seconds to less than 5, while battery life has been lengthened from 1 or 2 months to more than 2 years, saving costs and reducing the need for frequent maintenance.

ofo’s cooperation with Huawei on NB-IoT smart locks bodes well for improving the industry as whole. Huawei’s technology optimizes lifecycle management for locks, while the sensors on the locks collect information such as equipment status, user data, and operating data. They connect the front- and back-end industrial chains to achieve intelligent business management, enable the bikes to be located in hot spots, facilitate rapid maintenance, and boost marketing and value-added services.

This video gives an idea of how this works:



As per Mobile World Live:

Ofo co-founder Xue Ding said during a presentation the high power efficiency and huge capacity of NB-IoT make the technology ideal to deliver its smart locks, which are really the brains of its operations.

The company offers what is termed station free pushbike hire, meaning bikes can be collected and deposited from any legal parking spot. Users can locate bikes using their smartphone, and unlock it by scanning a barcode.

However, the process can be interrupted by mobile network congestion or if signals are weak – for example in remote areas: “Using NB-IoT, users will not be stuck because of inadequate capacity,” Xue said.
...
Xiang Huangmei, a VP at China Telecom’s Beijing branch, said the low power consumption of the NB-IoT chip in the lock means the battery will last eight years to ten years, so it will never need to be replaced during the standard lifecycle of an Ofo bike.

The NB-IoT network, deployed on the 800MHz band, offers good indoor and outdoor coverage, the VP said citing car parks as an example. One base station can support 100,000 devices over an area of 2.5 square-km.

Finally, to know which operator is supporting which IoT technology, see the IoT tracker here.

Smartphones, Internet Trends, etc

Every few years I add Mary Meeker's Internet Trends slides on the blog. Interested people can refer to 2011 and  2014 slide pack to see how world has changed.


One of the initial slide highlights that the number of smartphones are reached nearly 3 billion by end of 2016. If we looked at this excellent recent post by Tomi Ahonen, there were 3.2 billion smartphones at the end of Q1 2017. Here is a bit of extract from that.

A tale of two Smart Cities

Over the last few months I heard quite a few talks about Smart Cities. Here are two that I thought its worth posting and a very good TEDx talk at the bottom



I think we all agree that more and more people will move from rural to urban areas and the cities will not only grow in population but also in size. The infrastructure will have to grow to be able to cope with the influx of people and increased demand on services.



I guess in most developed nations we have the 1.0 Era Digital City which is long way away from the 3.0 Era Smart City.



To be a full fledged 3.0 Smart City, every aspect of our life may need to evolve into "Smart". Anyway, here is the complete presentation:





While IoT would be important, access, big data, applications, etc. all will have a role to play.



If you want to find out more about the Milton Keynes smart city, also see this video on Youtube. There are driverless pods and other autonomous cars which may be considered as initial step towards smart cities, see this interesting video here.

Finally here is the TEDx talk about designing these smart cities for future:

Internet Trends 2014, by Mary Meeker



Its June, time for the Internet Trends update by Mary Meeker, KPCB. Last year's update has crossed 3 million views on Slideshare. So many interesting slides, difficult to pick up some of the best ones to add here. I have selected a few that I really liked. The first being the growth in Smartphones and Tablets, as compared to PC's and Television's.



The other very interesting point to highlight is that the number of SMS's are decreasing and the number of OTT messages are rising. Just two days back, BITKOM, Germany released the news that SMS's are declining drastically in Germany. OTT's are taking over, rightly so.



Finally, with people doing too much multi-tasking, the above slide highlights what people are doing while watching TV.

Here is the complete set of slides:

The Rise and Rise or '4G' - Update on Release-11 & Release-12 features

A recent GSMA report suggests that China will be a significant player in the field of 4G with upto 900 million 4G users by 2020. This is not surprising as the largest operator, China Mobile wants to desperately move its user base to 4G. For 3G it was stuck with TD-SCDMA or the TDD LCR option. This 3G technology is not as good as its FDD variant, commonly known as UMTS.

This trend of migrating to 4G is not unique to China. A recent report (embedded below) by 4G Americas predicts that by the end of 2018, HSPA/HSPA+ would be the most popular technology whereas LTE would be making an impact with 1.3 Billion connected devices. The main reason for HSPA being so dominant is due to the fact that HSPA devices are mature and are available now. LTE devices, even though available are still slightly expensive. At the same time, operators are taking time having a seamless 4G coverage throughout the region. My guess would be that the number of devices that are 4G ready would be much higher than 1.3 Billion.

It is interesting to see that the number of 'Non-Smartphones' remain constant but at the same time, their share is going down. It would be useful to breakdown the number of Smartphones into 'Phablets' and 'non-Phablets' category.

Anyway, the 4G Americas report from which the information above is extracted contains lots of interesting details about Release-11 and Release-12 HSPA+ and LTE. The only problem I found is that its too long for most people to go through completely.

The whitepaper contains the following information:

3GPP Rel-11 standards for HSPA+ and LTE-Advanced were frozen in December 2012 with the core network protocols stable in December 2012 and Radio Access Network (RAN) protocols stable in March 2013. Key features detailed in the paper for Rel-11 include:
HSPA+:
  • 8-carrier downlink operation (HSDPA)
  • Downlink (DL) 4-branch Multiple Input Multiple Output (MIMO) antennas
  • DL Multi-Flow Transmission
  • Uplink (UL) dual antenna beamforming (both closed and open loop transmit diversity)
  • UL MIMO with 64 Quadrature Amplitude Modulation (64-QAM)
  • Several CELL_FACH (Forward Access Channel) state enhancements (for smartphone type traffic) and non-contiguous HSDPA Carrier Aggregation (CA)
LTE-Advanced:
  • Carrier Aggregation (CA)
  • Multimedia Broadcast Multicast Services (MBMS) and Self Organizing Networks (SON)
  • Introduction to the Coordinated Multi-Point (CoMP) feature for enabling coordinated scheduling and/or beamforming
  • Enhanced Physical Control Channel (EPDCCH)
  • Further enhanced Inter-Cell Interference Coordination (FeICIC) for devices with interference cancellation
Finally, Rel-11 introduces several network and service related enhancements (most of which apply to both HSPA and LTE):
  • Machine Type Communications (MTC)
  • IP Multimedia Systems (IMS)
  • Wi-Fi integration
  • Home NodeB (HNB) and Home e-NodeB (HeNB)
3GPP started work on Rel-12 in December 2012 and an 18-month timeframe for completion was planned. The work continues into 2014 and areas that are still incomplete are carefully noted in the report.  Work will be ratified by June 2014 with the exception of RAN protocols which will be finalized by September 2014. Key features detailed in the paper for Rel-12 include:
HSPA+:
  • Universal Mobile Telecommunication System (UMTS) Heterogeneous Networks (HetNet)
  • Scalable UMTS Frequency Division Duplex (FDD) bandwidth
  • Enhanced Uplink (EUL) enhancements
  • Emergency warning for Universal Terrestrial Radio Access Network (UTRAN)
  • HNB mobility
  • HNB positioning for Universal Terrestrial Radio Access (UTRA)
  • Machine Type Communications (MTC)
  • Dedicated Channel (DCH) enhancements
LTE-Advanced:
  • Active Antenna Systems (AAS)
  • Downlink enhancements for MIMO antenna systems
  • Small cell and femtocell enhancements
  • Machine Type Communication (MTC)
  • Proximity Service (ProSe)
  • User Equipment (UE)
  • Self-Optimizing Networks (SON)
  • Heterogeneous Network (HetNet) mobility
  • Multimedia Broadcast/Multicast Services (MBMS)
  • Local Internet Protocol Access/Selected Internet Protocol Traffic Offload (LIPA/SIPTO)
  • Enhanced International Mobile Telecommunications Advanced (eIMTA) and Frequency Division Duplex-Time Division Duplex Carrier Aggregation (FDD-TDD CA)
Work in Rel-12 also included features for network and services enhancements for MTC, public safety and Wi-Fi integration, system capacity and stability, Web Real-Time Communication (WebRTC), further network energy savings, multimedia and Policy and Charging Control (PCC) framework.

Nokia Siemens Networks demonstrate TD-LTE leadership

Since last few months, NSN have been showing that they are serious about TD-LTE as well. Back in June they made an announcement that they have integrated TD-LTE in their networks so that it can support concurrent use of TD-SCDMA and TD-LTE. They opened a TD-LTE lab in China as well earlier this year.

Motorola is another big player in the TD-LTE arena and I have blogged about them as well. With the purchase of Motorola Networks by NSN, it got additional experience and capability to be the next TD-LTE leader. With this renewed confidence, it ended the joint venture with Huawei which started back in 2005 with TD-SCDMA technology.

The following is press release from NSN couple of days back:

Nokia Siemens Networks has proven its leading role in advancing TD-LTE as it met the complete TD-LTE test specifications defined by China’s Ministry of Industry and Information Technology (MIIT). The successful completion of the trial in the 2.3GHz band at the MIIT lab in Beijing, China, marks an important milestone in the commercialization of TD-LTE. After the test, Nokia Siemens Networks also achieved the world’s first high-definition TD-LTE video call, including handover, with a Samsung TD-LTE device.

The high-definition video call demo showcased interoperability between Nokia Siemens Networks’ LTE infrastructure and Samsung’s TD-LTE USB dongle, and marks a definitive step toward ensuring early availability of a functioning TD-LTE ecosystem for commercial deployments.

“We’ve achieved excellent results from this test and are happy to partner with Nokia Siemens Networks in driving the TD-LTE ecosystem further,” said Mr. Tong Wang, president of Beijing Samsung Telecom R&D Center. “Commercial readiness of devices is a key indicator for the success of a new technology and the current test results show that we are now well prepared for TD-LTE.”

“Meeting TD-LTE test specifications defined by MIIT and achieving the first high-definition video call with handover, are key milestones in our list of achievements, added Paul Pan, head of Network Systems, Greater China Region, Nokia Siemens Networks. “We will continue to collaborate with partners to accelerate our progress toward a comprehensive deployment of TD-LTE.”

Nokia Siemens Networks is at the forefront of TD-LTE development and commercialization, actively working with telecom operators and device manufacturers. The company recently announced the first TD-LTE interoperability data call with a prototype TD-LTE USB dongle from Samsung and the first TD-LTE video call between Shanghai and Taipei.


Ericsson is now going to probably have tough competition from NSN.

Mobile TV in China not as successful as initially thought


A wise consultant once told me that when the analysts were asking people if they would be interested in Mobile TV, nearly everyone said yes. What they didnt ask is what those people understood by Mobile TV. From a lot of users perspective, Mobile TV meant Youtube which is not what mobile community understands it to be.

Not long back we talked about Mobile and IP TV becoming popular in China. According to recent news in InformationWeek, it falling much short of expectations:

Commercial development of China's mobile TV service is falling far short of expectations. Of the 1.5 million users of China multimedia mobile broadcasting (CMMB), less than 3% are actually paying for the service, creating something of an embarrassment for China Mobile, the main backer of the standard.
CMMB was developed by the State Administration of Radio, Film, and Television (SARFT) based on Satellite and Terrestrial Interactive Multiservice Infrastructure (STiMi) developed by TiMiTech, a company belonging to the Chinese Academy of Broadcasting Science. The standard was announced in October 2006 and is similar to Europe's Digital Video Broadcast-Handheld (DVB-H) broadcasting standard. Since then CMMB has been rigorously promoted by China Mobile and is bundled with its 3G network.
Sources say that by the end of the second quarter, 2010 domestic sales of CMMB handsets were around 1.5 million, approximately 30% of total 3G mobile phone sales at China Mobile, and much lower than the 50% target set by the operators. The service has been operational for more than a year but formal fees have only recently been introduced, which range from $1 to $3 per month. The small take-up of the service since fees were introduced does not bode well for the future of mobile television in China.
China Mobile was hoping to attract more paying customers with its World Cup offering, but this may have been wishful thinking. Analysts believe that the company's broadcasting and mobile communications divisions are lacking in unified policy and have no clear development path.
With widespread proliferation of cheaper "shanzhai" -- or copycat -- handsets, it is difficult to reach all potential customers. The CMMB technology is expensive and can only be found in specific dedicated smartphones.

Furthermore, there are more attractive and diverse streaming packages available from third parties. A clear advantage needs to be provided in order to entice users to use CMMB. China Mobile insiders say that they need to be following the advertising model used by mobile broadcasters in other countries because people are unlikely to pay for content, especially if they can find that content for free from a regular TV or desktop computer.

'Internet Kill' switch and IPv9

Slightly off topic today as I was going through the pile of information and I caught attention of this news article that for some reason has not been reported by major newspapers. The article says that the president of USA will have the 'Kill' switch to kill off internet (temporarily i guess) in case of a major emergency like war, etc. Joseph Liberman who proposed this idea has since then backed away saying that he meant that parts of Internet can be disconnected like they do in China.

This brought into attention the other article I was going through about IPv9. Yes thats correct, I did write IPv9. I first heard about IPv9 back in 2004-5 but then it was dismissed as nothing serious. Apparently Chinese government backed Ministry of Information Industry (MII) has been promoting this IPv9. According to an old TelecomAsia.net article:

Back in July 2004, reports of a Chinese IPv9 prompted a bewildered reaction from internet godfather Vint Cerf. 'What could this possibly be about‾ As far as I know, IANA [Internet Assigned Numbers Authority] has not allocated the IPv9 designation to anyone. IPv9 is not an Internet standard. Could you please explain what is intended here‾" he wrote in an email to China's internet leaders.

The idea was dismissed as a "rogue" project with no official backing. But it is back on the table led, now as then by Xie Jianping, the head of the Shanghai Universal Institute of Chemical Technology and more recently in charge of the decimal network standards team in the MII's science and technology department.

The project returned to prominence at a press conference at the unusual location of the Party Central School in Beijing two weeks ago, where Xie announced that the networking technology had been successfully tested by China Netcom and the Ministry of Commerce.

He asserted that the project is all about China wresting control of its own IP networks away from US dominance for which, he claimed, China was paying 500 billion yuan a year.

The system reportedly uses numerical addressing to make China "the only country able to unify domain names, IP addresses and MAC addresses" into a single, metric system, according to Xinhua. Without any explanation, Xinhua said it also made China the only country outside the US "to have root servers and IP address hardware connectivity servers and its own domain name, IP address and MAC address resources".

In an interview with a skeptical Sina reporter, Xie and denied the project was another Hanxin - a reference to a fraudulent state-backed chip project.

"Our IPv9 has gone through testing and assessment," he said adding that he could not give any more detail but would "make public some material at the necessary time."

But the system, or what little is known of it, has plenty of doubters at home. Sina said critics of the system complain that turning domain names and brand names into numerals is a "backwards step" for the net.

The fact that the decimal network appears to asset control over root servers is bound to alarm internet governance bodies around the world.

And whatever else might be said about it, the project is clearly backed by the MII. "IPv9" raises more questions than answers.

So it looks like the Chinese government may have been expecting some 'Kill Switch' in the future by the US government and is probably creating a backup based on a new approach so that the users within China remain connected to their Internet.

Any thoughts and opinions are more than welcome...

MBMS, Digital TV and IP Triple Play in China

Apparently according to this report by Xuefei (Michael) Peng, MBMS is alive and kicking in China with around 200,000 users already. I cant find more info so if anybody who can fill more info is more than welcome.

The government of mainland China has formulated a general plan to launch triple-play services, integrating telecom networks, broadcast and TV networks, and Internet together.

From 2010 to 2012, China will focus on the trial integration of broadcast and TV services and telecom services (including Internet services), dealing with any related policies. From 2013 to 2015, based on the trial experience, China will promote the integration nationwide.

In the coming five years, various sectors will prepare in different ways to meet the goals stated in the general plan. Telecom operators such as China Mobile, China Unicom, and China Telecom will invest more to promote IPTV services and accelerate FTTX deployment. Meanwhile, broadcast and TV operators will accelerate cable-TV network integration and interactive TV services development and will more actively develop value-added Internet services.

Broadcast and TV operators are currently strong in video content and wireless broadcast, while telecom operators own two-way fixed-line networks, mobile networks, and Internet services.

The differences between broadcast and TV operators across different regions and the uneven distribution of telecom fixed-line networks and mobile networks can offer cooperation opportunities.

Notably, almost all provinces of China already have launched IPTV services. The total number of IPTV service users in China has exceeded 5 million. However, problems with IPTV content must be solved, and the price for IPTV services also needs to be lowered to attract more users and compete with digital TV.

Meanwhile, the transformation of cable-TV networks from one way to two way has been sped up. Two-way cable-TV networks now cover over 24 million users. In the coming three years, broadcast and TV operators will invest over US$5 billion to continue to change 100 million one-way cable-TV links into two-way cable TV.

Eventually, through cable-TV networks, broadcast and TV operators hope to run Internet access services. This has been in trial use in some provinces. In order to run Internet access services, however, broadcast and TV operators need to rent bandwidth from telecom operators, greatly increasing the potential cost of service.

Another aspect of the triple play involves the conversion of mobile services to triple play. Mobile-phone TV is an emerging service in China. Up to now, mobile-phone TV services based on the China Multimedia Mobile Broadcasting (CMMB) standard have reached 1.5 million users. However, the current CMMB standard only supports one-way communication. So the users can only receive broadcast-TV programs via mobile.

On the other hand, mobile services based on the broadcast multicast Multimedia Broadcast Multicast Service (MBMS) standard serve about 200,000 users. The growing 3G user base will convert to the MBMS standard. Additionally, the government policy will affect the mobile-phone TV market too. So it is not clear yet which mobile-phone TV standard will dominate the industry in the future.

ZTE shows off its green credentials

ZTE has long been focussing on green(er) network and recycling. They launched their new generation 'green base stations back in 2006. They have also been recently cited for their energy saving technology. They also have a solar powered phone which is unfortunately not available in UK. Their Omni-RAN network can help reduce the OPEX by two thirds. Their focus has not only been on Mobile phones and networks but on the fixed lines as well.

So it was not at all surprising to hear Xiaodong Zhu, CTO of ZTE European marketing in the LTE World Summit talking about the end to end green networks. Green technology is not only helpful to for the 'green credentials' but it can also help reduce Opex which can help recover any additional investments (if any).

More manufacturers will hopefully follow the lead.

Softbank and Ericsson for TD-LTE as well

Last week I blogged about TD-LTE in India and China, today I found out that there is more interest in TD-LTE:

From Fierce Wireless:

Ericsson, the world's largest wireless infrastructure vendor, is looking to gain more expertise is the area, and this week signed an MoU to create a strategic cooperation with Datang Telecom in China to develop TDD solutions and likely gain a foothold in China Mobile's planned TD-LTE network.

As part of the deal, Ericsson will begin integrating Datang's TD-SCDMA radio access network equipment into its own 3G offering. TD-SCDMA is China's homegrown 3G standard that China Mobile and others are using. TD-LTE is seen as the next generation of TD-SCDMA.

From Telecom Asia:

Japanese cellco Softbank Mobile is considering deploying the Chinese-developed TD-LTE standard as a 4G network.

Senior executive vice president Ted Matsumoto told telecomasia.net the company could deploy it in the 2.5GHz spectrum it gained access to when it
bought a stake in failing PHS operator Willcom last month.

But he said
Willcom’s next-gen PHS technology, XGP, and mobile Wimax were also under consideration.

“We’re going to have 2.5GHz TDD spectrum, so we will seriously explore TD-LTE,” he said.

The XGP technology was “very much like TD, or at least is compatible with TD-LTE.”

Softbank is also focused on winning access to the key 700MHz or 900MHz frequencies, the “golden spectrum” with a much higher propagation range already that is used by both of its competitors.

“We’re fighting the handicap game [without those frequencies],” Matsumoto said. “There’s no 100% assurance, but we definitely will seek a 700/900MHz license.”

Japan’s Ministry of Internal Affairs & Communications plans to allocate 40MHz of spectrum in the 700/900MHz ranges for LTE and is now conducting a review.

For the time being, Softbank has put LTE plans on the backburner in favor of HSPA+.

It shut down its 2G network last month and is looking to reap the cost benefits of running a single 3G/3.5G network with up to 42Mbps download speeds.

All eyes on TD-LTE in India and China


The TD-SCDMA and Long Term Evolution (TD-LTE) network will be massively deployed in China, the world's largest telecommunications country by number of telecoms users, in 2010, globally premier international market research and consulting firm Infonetics Research said in a forecast report.
More and more mobile carriers have started developing the LTE, including Verizon Communications Inc., China Mobile Ltd., and China Telecom Corporation Ltd., Infonetics noted. There will be no more than twenty LTE networks in the world at the end of 2010.

China Mobile Communications, the largest mobile telecom carrier in China, will establish three experimental TD-LTE (time division-long term evolution) networks separately in three coastal cities - Qingdao, Xiamen and Zhuhai - beginning the third quarter of 2010, according to the China-based China Business News Daily.

China's Ministry of Industry and Information Technology (MIIT), the carrier, handset and component makers, and handset solution suppliers in China in late 2008 began to cooperate for the development of TD-LTE in three phases, the report said.

The first-phase trial of technological concepts completed in June 2009, and the ongoing R&D and experiments in the second phase will be finished at the end of June 2010, the report indicated, adding the third phase will begin with China Mobile setting up three trial networks in the third quarter.

China Mobile Communications, the largest mobile telecom carrier in China, on April 15 inaugurated its first experimental TD-LTE network at the site of the 2010 Shanghai World Expo.

The trial network consists of 17 outdoor TD-LTE base stations made by Huawei Technologies completely covering the 5.28km square site and will be used to provide mobile high-definition multimedia services.

ZTE and Datang Mobile Communications Equipment as well as Motorola and Alcatel-Lucent have also set up TD-LTE access points inside a number of pavilions.

Motorola, Inc.'s Networks business has already announced in February that it has successfully deployed a TD-LTE network at the Expo Center for World Expo 2010 Shanghai China, and completed the first indoor over-the-air (OTA) TD-LTE data sessions at the site. These advancements demonstrate another milestone of collaborative industry efforts on TD-LTE commercialization, reaffirming Motorola's commitment to address the future needs of TDD spectrum operators in China and around the world.

These milestones follow the announcement by China Mobile Communications Corporation (CMCC) in 2009, that Motorola was selected as main equipment supplier to provide indoor TD-LTE coverage for pavilions at Shanghai Expo. During the Shanghai Expo, Motorola will provide an advanced end-to-end TD-LTE solution and the world's first TD-LTE USB dongles. Motorola will also leverage its orthogonal frequency division multiplexing (OFDM) expertise with professional services to deploy, maintain and optimize these leading-edge networks. Visitors will be able to experience applications such as high-definition video on demand, remote monitoring and high-speed Internet access services.

Motorola, Inc.'s Networks business announced on April 16th that it showcased an end-to-end TD-LTE demonstration via the world's first TD-LTE USB dongle at the Shanghai Expo site to support the "TD-LTE Showcase Network Opening Ceremony" hosted in Shanghai on April 15. Delegates at the ceremony experienced applications that run over a TD-LTE network via USB dongles, including high-definition video wall (simultaneous 24 video streams), remote monitoring and high-speed Internet browsing applications. This latest advancement demonstrates a major milestone of the collaborative industry efforts in building a healthy TD-LTE device ecosystem, reaffirming Motorola's commitment to TDD spectrum operators around the world.

Motorola, a leading provider of TD-LTE technology, and China Mobile share the same commitment to accelerating TD-LTE commercialization and globalization. "We are very excited to support China Mobile in bringing the world's first TD-LTE USB dongle demonstration enabled by our TD-LTE system," said Dr. Mohammad Akhtar, corporate vice president and general manager, Motorola Networks business in Asia Pacific. "A healthy devices ecosystem has always been critical to the development, commercialization and success of wireless network technologies. We are working closely with partners to drive this ecosystem as demonstrated by the advancement announced today. TD-LTE is now a commercial reality and we are very pleased to see that industry players are joining forces to accelerate TD-LTE globalization."

Interest in TD-LTE continues to grow because of several key factors: the low cost of TDD spectrum that is particularly attractive to emerging and developing markets; operators' continuing need for more capacity and spectrum; and the ability to hand-off between TD-LTE and LTE FDD networks. In effect, this ability to roam between LTE FDD and TD-LTE means operators can use TD-LTE networks to augment their FDD LTE network for more capacity or other applications such as video broadcasting, while operators choosing to use TD-LTE as their "main" network can still offer their subscribers the ability to roam to other operators' FDD LTE networks in different countries. Motorola is one of the few vendors in the industry that has expertise in, and is committed to investing in both FDD-LTE and TD-LTE, as well as WiMAX. By leveraging its orthogonal frequency division multiplexing (OFDM) expertise and WiMAX legacy, Motorola has built up its leadership position in TD-LTE with a number of industry-firsts.

Nokia Siemens Networks has inaugurated a TD-LTE Open Lab at its Chinese Hangzhou R&D facility. TD-LTE smartphone and terminal manufacturers will be able to use the lab to test the interoperability and functionality of their devices across TD-LTE networks.

"The development of terminals and devices has always been a bottleneck in the roll-out of new mobile technology," said Mr. Sha Yuejia, vice president of China Mobile. "We are thus more than happy to see that Nokia Siemens Networks has established a cutting-edge terminal testing environment, an initiative that we support wholeheartedly. After all, a healthy ecosystem needs efforts from all stakeholders."

Nokia Siemens Networks' Open Lab will provide an end-to-end testing environment for verifying the compatibility of terminals and devices with the company's TD-LTE network products and solutions. The lab will also provide consultancy and testing services to device manufacturers. Nokia Siemens Networks' TD-LTE R&D center in Hangzhou is fully integrated into the company's global network of LTE Centers of Competence.

Providing a live TD-LTE experience to operators in the region, Nokia Siemens Networks also recently kicked off a nationwide TD-LTE road show in China. Beginning in Beijing, the road show will cover more than ten provinces in three months, demonstrating the most advanced TD-LTE technology and applications.

In India, Even as the government hopes to raise around $9 billion from the 3G and BWA auctions, foreign telcos waiting in the wings are eager to unfurl a new technology — TD-LTE —which is akin to 4G technology.

US-based Qualcomm and Sweden's Ericcson aim to piggyback on TD-LTE, hoping that it will help them gain a toe-hold in India, the world's fastest growing mobile market. Qualcomm is to participate in the broadband wireless access (BWA) spectrum auction. If it does secure its bid in the auction, India could well become the first country after China to roll out TD-LTE.

TD-LTE, or Time Division Long Term Evolution, caters to peak download speeds of 100 Mbps on mobile phones, compared to the 20 Mbps for 3G and 40 Mbps for Wimax. LTE brings to the table additional spectrum, more capacity, lower cost, and is essential to take mobile broadband to the mass market.

The government has slotted the sale of two 2.3 GHz blocks of spectrum on April 11, providing 20 MHz spectrum in each of the country's 22 telecom circles. The base price has been set at $ 385 million. However, Qualcomm will need an Indian partner for its TD-LTE foray in the country since foreign direct investment is limited to 74%.

The US telco aims to use the 2.3 GHz spectrum band offered for TD-LTE-based BWA services. Sources in the know told TOI that the company would bid aggressively to corner one of the two BWA slots up for sale. There are 11 bidders for the BWA auction.

Asked to comment on the market dynamics, Sandeep Ladda, executive director, PricewaterhouseCoopers (PWC), said: "Though the Indian market is huge, it won't be smooth sailing post auction. We are adding 1 crore customers a month and in January, we added 1.9 crore customers, but the implementation of the new technology has its own cost. And India is a very cost conscious market."

Eager to play by the rules in India, Qualcomm has notified that it would enter into a joint venture with an Indian partner to launch its services and later exit from the joint venture after the network becomes operable.
Meanwhile, The WiMAX Forum has gone on the defensive during the WiMAX Forum Congress Asia in Taipei, Taiwan. The group is speeding up its time table to deliver the next generation of WiMAX--a reaction to heavy data use among WiMAX subscribers as well as the looming threat posed by Qualcomm and Ericsson's lobbying for TD-LTE in India.

Recently, the forum launched a global initiative to accelerate advanced WiMAX features that would double peak data rates and increase average and cell edge end user performance by 50 percent.

Mo Shakouri, vice president with the WiMAX Forum, said enhancements to the current generation of WiMAX weren't on the forum's roadmap, but were brought to the forefront at the urging of several WiMAX operators already facing capacity crunches. The forum reports that the average usage of data on WiMAX networks is close to 10 GB. Clearwire recently reported that mobile users average more than 7 GB of usage per month. In Russia, mobile WiMAX operator Yota sees more than 1 GB per month in data traffic from subscribers using its HTC smartphone. For laptops, it's 13 GB per month.

"Demand for data is moving so fast that we were pushed by many people to add this functionality," Shakouri said.

The WiMAX Forum has also been prodded to announce more detailed plans for 802.16m, and step up the timeline for its development via a new group called the WiMAX 2 Collaboration Initiative, which is made up of vendors Samsung, Alvarion, Motorola, ZTE, Sequans, Beceem, GCT Semiconductor and XRONet. The companies will work in tandem with the WiMAX Forum and WiMAX operators to accelerate the next-generation standard. WiMAX 2, the marketing name for the 802.16m standard, is expected to expand capacity to 300 Mbps peak rates via advances in antennas, channel stacking and frequency re-use.

The forum previously forecast 802.16m would hit in 2012 or 2013. But increasing demands for data--coupled with Qualcomm and Ericsson urging Indian mobile broadband license bidders to go with TD-LTE--motivated the forum to put some stakes in the ground and declare that WiMAX 2 equipment will meet certification by the end of 2011.

"There has been a lot of noise about TD-LTE, and the WiMAX Forum had not specifically given dates regarding timelines for 802.16m," Shakouri said. "Basically our announcement around 802.16m came about because of the noise in India."

The formation of the WiMAX 2 Collaboration Initiative is a marked change from the way the first generation of WiMAX was developed. Sprint Nextel was the entity driving the majority of the standards work as it was eager to get to market and begin building an ecosystem. Vendors are now taking the lead and driving equipment readiness before the 802.16m standard is finalized by the end of this year. Shakouri said the standard is 95 percent finished.

"Those companies are going to take a more active role inside the forum," Shakouri said. "They have all come together to speed up the process."

The group of vendors plans to collaborate on interoperability testing, performance benchmarking and application development before the WiMAX Forum establishes its certification program to narrow the gap between the finalized standard and commercial rollouts.
So how much of a threat is TD-LTE to WiMAX? Shakouri said the answer depends on spectrum decisions. "At this moment, the spectrum we are focusing on is separate, aside from what Qualcomm announced in India," Shakouri said. He also said that a TD-LTE ecosystem is at least two to three years behind WiMAX.

Many analysts speculate that TD-LTE will become the crossover technology that will prompt WiMAX operators to flip to LTE. Clearwire was part of a group of operators and vendors that last month asked the 3GPP standards body to begin working on specifications that would enable TD-LTE to be deployed in the 2.6 GHz band, which Clearwire uses for WiMAX. During the CTIA Wireless 2010 trade show last month, Clearwire CEO Bill Morrow reiterated the company's interest in deploying LTE when the technology catches up to WIMAX. He also called for one standard down the road.
Another initiative the forum is announcing this week is the launch of its Open Retail Initiative, a global program aimed at driving WiMAX into consumer devices sold directly or through retail channels that can be activated by the consumer over the air on the network. If you remember the evangelism of early WiMAX advocates like Barry West, this capability was supposed to be the Holy Grail of the technology.
