KDDI Vision on FMBC (Fixed Mobile Broadband Convergence)

The following is from KDDI Annual report which is available to download here.


FMC (Fixed and Mobile Convergence) enables a variety of services and contents anywhere, any time, regardless of different communication methods and access means, be it fixed or mobile. KDDI’s next-generation infrastructure concept, “Ultra 3G,” takes this convergence one step further, to FMBC (Fixed Mobile and Broadcast Convergence). This is an area where only KDDI, which has various access lines, can pursue potentials.

The following is an article and half from the same report on FMBC:

Everyone is talking NFC



Its been over couple of years since I blogged about what NFC is. In fact successful trials in London occurred around that time but it seems the operators always had doubts.

Couple of months back, Nokia announced that from 2011, it will roll out NFC in all it phones. Here is an extract from the Register:

Nokia has announced that from next year every Nokia smartphone will have NFC, regardless of fact that the technology lacks a business model or any market demand.

The commitment was made during a speech by Nokia's VP for markets, Anssi Vanjoki to the Moby Forum, as
reported by NFC World. Vanjoki wouldn't be drawn on the company's smartphone plans, but did explain that every smartphone launched by Nokia would have an NFC component supporting the Single Wire Protocol (SWP) and MicroSD security, and probably a Nokia secure module too.

Once NFC is in a handset then one can do some interesting things with remote control of home electronics and Bluetooth pairing-by-tap, but none of that is the killer feature that NFC needs to make it viable.


Of course, the mobile industry isn't used to waiting for customer demand – no one ever requested a camera, or Bluetooth, those were pushed into punters' hands by operators (to sell MMS) and retailers (to sell headsets) respectively. But those were done by the network operators (which explains the popularity of Bluetooth in Europe, where operators own retailers).
Nokia, which has extensive IP in NFC, has spent a fortune trying to convince operators to back the technology, funding extensive trials and backing supportive research, but no matter how hard it tries, NFC just isn't desirable (at least until Apple puts it into an iPhone).


That was till last week. This week the news is out that Apple is testing NFC in iPhones. The following news from CNET:

Apple raised some eyebrows over the weekend when news spread it had hired an expert in mobile payments.

But now there's a report that says the company is already testing a prototype
iPhone with near-field communication (NFC) chips inside, which could pave the way for using future iPhones as a mobile wallet.

TechCrunch heard from an unnamed source that on Tuesday Apple is testing an iPhone with NFC chips it's ordered from NXP Semiconductor. It's not clear what kind of tests, and it could be very preliminary in nature. But coupled with the hire of Benjamin Vigier from mFoundry as mobile payments product manager, it does seem possible that Apple could be planning to open up its premier product to the world of commerce outside of iTunes.

In fact you may be able to do much more than mobile payments if Apple gets its way. You may be able to sync devices by touching each other. You can sync your MAC to iPhone or iPod. Here is a video showing some iPhone RFID demo, courtesy NFC world.

Over 100 HSPA+ Network commitments

From Mobile Business Briefing, via Wireless Intelligence:

Over a hundred global operators have now committed to rolling out HSPA+ networks, according to new Wireless Intelligence research. Our study shows that there were 58 live HSPA+ networks in operation at the beginning of August (see graphic) with a further 43 local operators having made commitments to migrate to the technology soon. There have been 19 HSPA+ network launches to date in 2010. The latest number of live networks means that HSPA+ now accounts for around 15-20 percent of the over 300 total HSPA network deployments worldwide. Significant new operators due to launch HSPA+ soon include AT&T in the US (due to launch by year-end with 250 million population coverage); Chunghwa and Far EasTone in Taiwan; Singapore's SingTel; Japan's SoftBank; and Germany's T-Mobile, O2 and E-Plus.

The growth in the number of HSPA+ networks comes just 18 months after Australian market-leader Telstra launched the world's first HSPA+ network in February 2009. The most recent operator to complete its HSPA+ upgrade was Qatar's Qtel, which switched on its new network in its home market this week, offering peak download speeds of 21Mb/s and 5.8Mb/s in the uplink.

The most common version of HSPA+ (64QAM) offers theoretical top speeds of around 21Mb/s though some operator deployments are aiming for HSPA+ speeds up to four times faster using dual-carrier and MIMO technology. Those already to have done so include Qtel's Indosat subsidiary in Indonesia, Etisalat in Egypt and
Japan's EMOBILE, which have all introduced the dual-carrier version this year.

Australia's Telstra has still to complete its
upgrade to 42Mb/s (due in 2H10) despite last year claiming that it had become the first operator in the world to test HSPA+ dual-carrier technology outside of laboratory conditions. Nevertheless, Telstra has been the most high-profile pioneer of HSPA technology to date, launching its HSPA-based 'Next G' network back in October 2006. The network initially offered top speeds of 3.6Mb/s but was subsequently upgraded to 14.4Mb/s and then – following the HSPA+ upgrade in February 2009 – to 21Mb/s. However, as is the case with most of the speeds advertised by operators, real world speeds on the network are significantly lower. A GSMA-backed study by Signals Research Group in December last year found that Next G's HSPA+ network only delivered downlink data rates above 5Mb/s around 50 percent of the time, with peak speeds of around 17Mb/s. It noted that this made HSPA+ broadly comparable with mobile WiMAX.

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.

Home Energy-Management solution using Femtocells



A recent demonstration from ip.access and AlertMe.com showed how femtocells can be integrated into smart-home energy-management solutions. With femtocell integration, the AlertMe Energy service can automatically detect when the house is empty and power down lights, televisions, and other home appliances. The service also can switch the services back on when the resident returns home.
For the demo, ip.access combined the AlertMe Energy service with its own femtocell technology. The solution works by allowing electrical appliances to switch on and off automatically in response to the presence or absence of mobile phones in the home. This “presence” information, which is routinely gathered by the femtocell, is normally only used to route cell-phone traffic and set tariffs.
In the demonstration, however, the AlertMe integration enables the presence information to be used to set light and power preferences, which are activated automatically when a subscriber arrives at home. Preset electrical outlets also can switch off automatically to save energy a few minutes after the last person has left the house.
The demonstration shows how supplementary service codes on the phone can be personalized through the femtocell when the phone is at home. For example, the phone can be used to remotely switch appliances on and off.
“One automatic trigger could be to switch the kettle on as soon as you arrive home,” says Dr. Andy Tiller, Vice President Marketing at ip.access. “But there is more to this than just tea and convenience. Using a femtocell to personalize supplementary service codes is a new and unique idea. It enables the mobile phone to become a powerful controller for all kinds of applications in the home. And because it’s a network-enabled feature, it works with any handset. There are no applications to install.”
According to AlertMe.com Founder Pilgrim Beart, “The mobile phone is increasingly the remote-control for your life. Most people carry their handset everywhere they go, making it an ideal control device for the AlertMe Energy service.”
The demo also shows how the AlertMe Hub (the central device that receives instructions via the Internet and controls the electrical plugs in the home) can be integrated inside a femtocell access point. It will then rely on the femtocell for power and its Internet connection. In this way, a mobile operator could offer a smart-home energy-management solution as an integrated option to its femtocell subscribers.

Whitepaper: Traffic Management Techniques for Mobile Broadband Networks


The report, Traffic Management Techniques for Mobile Broadband Networks: Living in an Orthogonal World,focuses on 3GPP networks and concerns itself specifically with traffic management, including the handling of traffic flows on 3GPP networks in contrast with other network management techniques that operators may deploy (such as offloading, compression, network optimization and other important mechanisms).

Mobile broadband networks are confronted by a number of challenges. In particular, the physical layer in mobile networks is subject to a unique confluence of unpredictable and unrelated, or “orthogonal,” influences. Moreover, mobile broadband networks have some important differences from their fixed brothers and sisters, which lead to different traffic management requirements. Among the most significant differences for purposes of traffic management is the need for more granular visibility to circumstances on the ground. Optimally, traffic management for mobile broadband networks requires visibility to what is occurring (by device or application) at the cell site level and in a timeframe that enables as far as feasible near-time reactions to resolve issues.

With the consumer in mind, an End-to-End (E2E) view of mobile service is critical for traffic management. For example, a consumer using a mobile phone to look up movie listings and purchase tickets considers the E2E service as the ability to see what movie is playing and execute a transaction to purchase tickets. 3GPP has endeavored to standardize increasingly more robust traffic management (Quality of Service, or QoS) techniques for mobile broadband networks with a consumer’s E2E view of QoS. It must be considered, however, that mobile operators typically do not have full control over E2E provisioning of services that depend on mobile broadband Internet access.

Global standards organizations like 3GPP play an important role in the development of traffic management through provisions for addressing QoS, particularly regarding interworking with non-3GPP access mechanisms. These are important new innovations, and the 3G Americas white paper notes that the efforts of standards development organizations should be intensified.

In addition, the configuration of end-user devices and content and applications not provisioned by the network operator not only impacts the experience of the particular user, but potentially other users in a particular cell as well. Efforts to drive further QoS innovations should be mindful of potentially adverse impacts from these sources and support and foster interoperability of third party applications with existing network platforms.

More innovations are needed throughout the mobile broadband ecosystem, in particular by application developers, in order to realize E2E quality of service. Furthermore, transparency in network management practices is important in fostering innovation, but requires a careful balancing to ensure consumer comprehension while safeguarding network reliability. Organizations with technical expertise such as 3G Americas are prepared to help to illuminate and progress the development of these new technologies.

“3G Americas stands ready to assist interested parties in the ongoing development and understanding of traffic management techniques,” said Chris Pearson, President of 3G Americas. “We are mindful that in this hemisphere and elsewhere, the industry has accepted an increasingly active role in addressing questions about service levels and innovation on mobile broadband networks.”

The white paper, Traffic Management Techniques for Mobile Broadband Networks: Living in an Orthogonal World, was written collaboratively by members of 3G Americas and is available for free download on the 3G Americas website at www.3gamericas.org.

AT&T on their LTE Backhaul Architecture


Backhaul is a topic that may be giving some operators nightmare. Picked up this slightly old article from Light reading via WirelessMoves.

AT&T network architect Yiannis Argyropoulos addressed the Backhaul Strategies and Core Convergence for Mobile Operators event in New York City and had the following to say:

The lines between wireless and wireline networks are blurring, as are the boundaries between access and core networks, driven by the need to carry the flood of wireless data traffic more efficiently. AT&T is aggressively deploying fiber to its mobile cell sites and migrating from Sonet to Ethernet, but more changes will be needed. AT&T started its fiber push in 2008, and it will take at least seven years to complete, said Argyropoulos.

For the short term, today's metro Ethernet architecture will support LTE, but longer term, the network architecture needs to have less operational complexity, noted the AT&T man. The carrier is in the process of testing new approaches, based in part on work being done by 3rd Generation Partnership Project (3GPP) and the Broadband Forum .

AT&T also is looking for coordination of policy control between its wireline and wireless networks, so that the core network services are the same for end-users, regardless of how they connect to the network. It is no longer adequate for quality-of-service to be delivered piecemeal, within different segments of the network, Argyropoulos stated: "There is a lot of work going on right now to harmonize these."

The early 3GPP scheme for QoS on 3G UMTS networks was too complicated to be implemented, but newer LTE QoS plans from the 3GPP, with nine QoS classes and a smaller number of individual class attributes, look more practical.




The growing volume of data traffic is having an impact on other areas of the carrier's operations, too. The widespread use of bandwidth-hungry smartphone devices is creating new traffic patterns that, among other things, eliminate traditional maintenance windows traditionally scheduled in the early hours of weekend mornings, Argyropoulos pointed out.

"Data traffic peaks at the same time as voice, but it has multiple peaks, and it doesn't ever really subside," he said. That, in turn, is putting pressure on wireless network operators and their vendors to do hitless network upgrades and to build more resiliency into their networks.

AT&T is looking to other means of offloading traffic, including routing optimization that will use gateways strategically placed in the network to direct traffic onto the Internet, and not carry it through the metro and core networks first.

"Most of the mobile data traffic is coming from the Internet and going to the Internet."

It will also be important to offload subscriber traffic generated in the home onto a domestic Internet connection, he added.

To get an Idea of the mobile backhaul load, see my earlier post here.

Along with Fiber, Microwave is also an option and you can read more about it in Daily Wireless blog.

Also came across this blod dedicated to mobile backhaul, that is available here.
