Operator Top Ten Requirements for the networks

Operation Requirements for next generation multi-technology networks are the key topic that brought 3GPP, NGMN and TM Forum together for a workshop held March 29-30 2010 in Bonn. The two-day workshop was attended by forty industry experts who worked on use cases and requirements in three parallel work streams and provided recommendations for next steps.

At the Bonn workshop, the 3GPP Telecom Management working group - SA5 - presented background data on the SA5 work program to date, much of which meets the needs of the NGMN Top Ten Requirements:

• Quality and Quantity of Alarms
• Automatic Software Management
• Energy Saving
• LTE Automatic Neighbour Relation (ANR) and Self Organizing Networks (SON) Operation
• Performance Management in Real-time
• Substitution of Monitoring Probes by Infrastructure Inherent Trace Functionality
• eNodeB Plug & Play Self-Commissioning
• OSS Standard Itf-N
• LTE Parameter Optimization
• Automatic Inventory

The workshop conclusions acknowledged that:

• Standards specified by SA5 over the last ten years provide a widely deployed, fully re-usable and expandable solution for management of Next Generation Networks,
• NGMN Top Ten Requirements are mostly satisfied already by 3GPP SA5 specifications, the missing functionalities will be addressed in 3GPP Release 10 (due December 2010),
• The ongoing 3GPP-TMF alignment program provides an excellent opportunity to address network management of Wireless-Wireline convergence based on the 3GPP IRP framework.

At the end of this workshop, the SA5 Chairman Christian Toche said:

"This workshop has identified important requirements and allowed TMF and 3GPP to compare their solutions that can satisfy Operators requirements, of whom many are already supported in 3GPP specifications. I am confident that, as long as the representation from each group is maintained at the right level, an alignment of the 3GPP and TM Forum specifications will result from this cooperation, satisfying the requirements for use in convergent network operational environment."

Christian Toche identified that the next step includes the need for the two ongoing Network Management harmonization projects with the TM Forum - On FM and resource modelling - to be completed.

Further progress on the alignment of 3GPP and TMF specifications will be made at the follow-up workshop on May 6-7, 2010 in Montreal

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.

Pervasive connectivity means that we are working far more

Picture source: dmb

From the IET Magazine:

All of which led to it being no surprise that research from Nectar Business is headlined 'Workaholic Brits just can't switch off', according to the release. Far from saving us time and bringing quality back to our lives, Nectar - the loyalty card people - have found that we're working on average an extra 10 days a year.

Some of the headline results are alarming for managers wanting to keep a workforce motivated and fresh. They include:

• a fifth of people keep work phones on over weekends;
• 79 per cent of workers haven't met half the people with whom they do business;
• one-third of men turn their work phones off when they leave the office;
• one in 20 people get over 100 emails a day;
• twenty-four per cent of people feel stressed by this constant state of being on call;
• 42 per cent of people say they meet colleagues less regularly due to email dependence;
• 60 per cent - get this - now say they prefer to communicate by mail than face to face.

That's a lot of figures. However, some of the findings were positive - 71 per cent of people found email the best way to keep colleagues informed and 28 per cent thought it a useful tool for delegating. But that still leaves a quarter of respondents stressed.

GPS to become commonplace and far more accurate

First it was Nokia that started giving away the Satnav software for free. Now Google is offering free Satnav software for Android phones in UK. Its already been available in US for quite some time and the response is generally positive.

According to comScore, the use cellphones for Satellite Navigation is becoming more common in Europe. According to them, in February, 21.1 million consumers in five large European markets -- Britain, France, Germany, Spain and Italy -- used their cellphones for navigation, 68 percent more than a year ago. This compares to 20.4 million personal navigation devices sold in those markets in 2008 and 2009 in total, according to research firm GfK.

I talked about Satellite based Internet before but today we will focus on satellite based GPS systems.

The GPS system, which was developed way back in 1989 for and by the military has been used by general public since the year 2000. Its has become very common in the last few years.

The GPS we know and love is part of a larger family of systems called Global Navigational Satellite Systems or GNSS. The following are the members of the GNSS; GPS is the USA system, GLONASS is the Russian system, Galileo is the European system and Compass is the Chinese system

The following is from the IET Magazine:

Satellite navigation systems take their location cues from 30 GPS satellites that circle the Earth twice a day transmitting status, date and time, and orbital information. Soon there will be around 100 satellites to lock on to as GPS is joined by global constellations from Europe (Galileo), Russia (GLONASS), and China (Compass).

GPS wasn't built to help us find our way to the shops - it was a Cold War project funded by the US Department of Defense to ensure that nuclear submarines could surface and target their missiles accurately. There are strategic rumblings about the new satellite constellations too, but the current consensus is that civilians have most to gain from more accurate and reliable location and tracking applications. That's if receiver designers can get the power consumption under control.

Russia's GLONASS system used to be famous for its satellites failing faster than they were launched, but since last month it has had 24 functioning satellites in orbit. Meanwhile, Europe's much-delayed Galileo system will have 14 satellites operating by 2014, according to the European Commission, with the full 30 available by 2017. The US GPS system is being modernised to become GPS III by 2013, with additional navigation signals for both civilian and military use. Information about China's Compass system is sketchier - it was going to be a regional system but is now understood to be global.

'All this activity is great news because whatever the application, there will potentially be multiple constellations to get a position fix from, which will help with signal integrity in safety-critical environments such as maritime, aviation or rail, and accuracy for mobile phone users in urban areas,' says Andrew Sage, director of Helios, a consultancy specialising in satellite navigation.

A GPS receiver should be able to 'see' at least four GPS satellites anytime, anywhere on the globe and establish three position coordinates (latitude, longitude, and altitude). But in city streets hemmed in by tall buildings, a receiver is unlikely to be able detect more than two satellites and the signals will often have bounced off structures.

'For the average pedestrian, the position fix can be a long way out and very unpredictable,' says Sage. 'Most users don't see that today because GPS receivers match us to maps and smooth the errors out. But if you are walking around a city and not on a road in a car, multi-path reflections are a problem.'

The more satellites visible from within these 'urban canyons', the easier it is to carry out consistency checks on the received signals. 'Even when you can't isolate the multipath-contaminated signals, the more signals you have, the more your errors average out,' says Dr Paul Groves, lecturer in global navigation satellite systems (GNSS), navigation and location technology at UCL.

Better GNSS integrity would enable new applications, such as road-user charging, enforcing bail conditions and pay-as-you-drive insurance. 'Clearly, if position information might be used as legal evidence, it has to be reliable,' says Groves.

The delayed arrival of Galileo and the resurrection of GLONASS have complicated matters for receiver makers. Galileo was designed to offer the simplest possible upgrade path from GPS to a dual-constellation system. Agreements were made to put the carrier frequencies of the main open services in the same part of the spectrum as GPS, at around 1575MHz, so receivers could share the same radio, analogue components and antenna. Both systems also send their signals using a spread-spectrum code-division multiple-access (CDMA) approach. GLONASS uses a frequency-division multiple-access coding technique (FDMA) and a main open-service carrier frequency of 1602.2MHz.

When Femtocells become Picocells

Femtocells are not really becoming Picocells but when you read about the new features coming up in Femtocells, you can imagine why operators are embracing Femtocells.

A typical Picocell, offers limited coverage but the same capacity as a macro-cell and can cost between £5000 to £10000. A Femtocell overs very limited coverage and very few users but its dirt cheap.

What if a compromise Femtocell is made that can solve both the coverage/capacity and price then its a win win situation for everyone.

This is where "Metro Femtocells" come into picture. They can be called by different names but lets stick to Metro Femtos.

Ubiquisys's press release about the Colo-Node HSPA Femtocell shows us the direction in which the device manufacturers are moving. It allows 16 users (as opposed to 4) and the range of 2km (as opposed to couple 100 metres). Picochip has already released a chip that can serve 32 users at 2km range. These femto's are Release-7 compliant with 42Mbps peak dl and and 11Mbps peak ul.

The good thing is that they may be soon used to fill the coverage black holes but that can also mean that the operators may stop putting lot of effort in Network optimisations.

The ubiquisys Colo-Node HSPA will be available end of July this year.

Ubiquisys has also demonstrated a wide area femtocell with 12 sq. km range. I wonder where they will be used.

The WiMAX taxis of Taiwan

LTE wont be coming to Taiwan until 2017. In fact, I am hoping that LTE-A would be available by then and Taiwan can skip LTE completely.

Taiwan is pushing WiMAX as a lot of small manufacturers based in Taiwan jumped in the WiMAX bandwagon at its peak. The main advantage with WiMAX being that there is no legacy GSM/UMTS baggage so the things are relatively simple. Having said that, this is also the main reason operators have not embraced the WiMAX technology.

See the Video above before reading the report from Telecom Asia below:

I’ve been to a number of Wimax conferences in the past few years, but this year’s Wimax Forum Asia show in Taipei marks the first time I could walk out of the conference hall and see a demo of Wimax in action.

As Telecom Asia reported last month, Vmax has launched a Wimax service in the capital, offering connectivity to 1,000 taxis.

I managed to catch one of them. The Wimax set-up featured a GPS-enabled touchscreen MID mounted on the back of the front passenger seat. Among other things, I could access a real-time navigation app that also displayed our driving speed, and – of course – streaming music videos.

The video was the real test, and it was YouTube quality – which is to say, acceptable – for the entire 15-minute trip.

If Vmax chief Teddy Huang is right about the service yielding “much more” than NT$500-NT$600 in ARPU per user, it’s not a bad testament to Wimax’s potential to carve out these kind of B2B niche services.

Or to allow users to come up with their own solutions. Another taxi I rode in had a mounted laptop next to the driver that was running GoogleMaps whilst playing a live local TV channel with good video quality.

Video Calling: Boon or Bane?

When 3G was launched, the operators were clueless as to what 3G can do. The only way according to them to sell 3G was to to market 'Video calling'.

I am not sure how many of you have used Video calling, but I love it. Shame that the operators have priced it so ridiculously that I only used it when I had them inclusive in my package. Otherwise paying £0.50 per min seems exorbitant to me.

We have so many other options like Google Chat with Video and Skype Video chat available which is very convenient (and far much cheaper) according to me. Skype client is available on mobiles but still Video is not included. Its just matter of time before Video calling is included part of the VoIP client. All handset manufacturers are scared to include the feature so as to avoid the ire of operators. Maybe we will have to leave it to iPhone again to break this barrier as well.

The following is from Reuters news article:

Research in Motion Ltd says it is far from certain that video will become the "killer app" that defines smartphones, but even so the BlackBerry maker says developing more efficient delivery is necessary to prevent video from choking airwaves.

The popularity of feature-rich smartphones such as the BlackBerry, Apple's iPhone, and Motorola's Droid has surged, but they use as much as 30 times as much bandwidth as regular mobile phones to run the applications, or "apps," that make them so popular.

The surge in traffic triggered by video and other apps has led to more dropped calls and choppy service. As video on smartphones becomes more popular, it is leading to more congestion, and forcing carriers to spend billions to upgrade networks and buy more wireless spectrum.

"I still don't know and I don't think anyone knows if video is a killer app for smartphones," RIM Co-CEO Mike Lazaridis said at a conference hosted by a unit of Toronto Dominion Bank on Friday. "I don't particularly think it is."

Lazaridis said that even if video did not become the defining app for smartphones, it is already presenting a big challenge to networks.

Analysts have praised Waterloo, Ontario-based RIM for its relatively bandwidth-light BlackBerrys, which route most emails through the company's own servers. This is a legacy of the company's earlier days when it was seeking a faster, more secure mobile email service.

RIM also sends web browsing, Facebook, Twitter, and data from a wide number of BlackBerry apps through its own servers.

That makes browsing and using apps on a BlackBerry three to eight times as efficient bandwidth-wise as on the devices of RIM's rivals, said Lazaridis.

"What that means for the carrier, though, is after they have committed all those billions of dollars on new network technology and new network spectrum, they can have three BlackBerrys using the same network capacity as one of the other smartphones."

Lazaridis said RIM would invest more in technology that provides efficiencies to carriers, including when it comes to video.

He pointed to RIM's 2006 acquisition of SlipStream, which specializes in data acceleration, compression and network optimization technology.

"They had some amazing technologies for compressing everything from web content, documents, and video. So, you never know, the research that we do is very important, it's always borne fruit and we are hoping that we can continue to ... provide tangible efficiencies to the carriers."
