800MHz to be reserved for LTE and WiMAX in Europe

We were having a discussion in the LTE Linkedin group couple of days back about when devices would be ready in bands other than 2.6Gz. The 2.6GHz band has become a de facto standard for LTE but there are other bands at much lower bands that are gaining interest as well.

Here is something from Cellular News today:

The European Commission has adopted a Decision establishing harmonised technical rules for Member States on the allocation of radio frequencies in the 800 MHz band that contribute to the deployment of high-speed wireless internet services by avoiding harmful interference.

In several Member States the 800 MHz frequencies are being freed up as part of the so-called "digital dividend" resulting from the switchover from analogue to digital television broadcasting. If Member States decide to change the existing frequency allocation (for broadcasting) they must immediately apply the harmonised technical rules laid down by the Decision to make these frequencies available to wireless broadband applications. Today's decision does not itself require Member States to make available the 790-862 MHz band for electronic communication services. However, the Commission is considering such a proposal in the forthcoming Radio Spectrum Policy Programme.

The Commission strongly supports the use of the 790-862 MHz band (currently used for broadcasting in most Member States) for electronic communication services and wants EU countries to act quickly, as coordinated management of this spectrum could give an economic boost of up to EUR44 billion to the EU's economy and help to achieve the EU 2020 Strategy target of high-speed broadband for all by the end of 2013 (with speeds gradually increasing up to 30 Mbts and above in 2020).

The new Commission Decision stipulates that all Member States which decide to make available the 790-862 MHz spectrum band (the so-called 800 MHz band) for services other than broadcasting should apply the same harmonised technical rules when they do so. These technical rules will ensure that radio communications equipment, like handsets or base stations using the 800 MHz band, can be used efficiently for wireless broadband networks, such as LTE or WiMAX.

Telecoms industry experts estimate that infrastructure to provide mobile broadband coverage using the 800 MHz band will be around 70% cheaper than through using the radio frequencies currently used by 3G networks. The lower costs involved in rolling out such networks will make these investments more attractive for operators, which should improve the geographic coverage of wireless broadband services. Application of the technical rules for frequency allocation foreseen by this Decision will substantially increase the potential economic benefits of the digital dividend by giving a new impetus to wireless internet services.

Until now, the 800 MHz band has been used for terrestrial TV broadcasting in most Member States. The new rules laid down in the Decision set out conditions for allocation of nearly one quarter of the frequencies that will become available when Member States switch from analogue to digital broadcasting (due by end 2012). The Commission is currently working on a Radio Spectrum Policy Programme that will take into account the other elements of the digital dividend and may also include a common date by which all Member States must make the 800 MHz band available.

Avren's Next Generation Networks & Basestations Conference Summary

Interesting summary on Next Generation Networks & Base stations conference is available on Think Femtocell and Avren's website. Here are some interesting bits:

• Operating a mobile network contributes around 30% to the annual costs of each operator, and there are many different ways to save money. Where before, coverage was a real differentiator between networks, today it’s much more about service.
• There are enormous savings to be made by sharing cellsites between operators – T-mobile and 3 in the UK have combined their cellsites and reduced the total number from 55,000 to 31,000 in the last two years. The number is now slowly expanding again to fill in coverage holes and add capacity. The recently announced merger between Orange UK and T-Mobile means a further round of site consolidation over the coming years. Meanwhile, their UK competitors O2 Telefonica and Vodafone have also made a site sharing agreement, meaning that there will be just two competing sets of cellsites across the country.
• Some speakers questioned the sense of offering unlimited flat rate data plans – the industry sentiment is that these can’t last. The highest traffic users are consuming disproportionate amounts of network resources – several examples were given of 2 or 3% of users taking up over 40% of available capacity.
• Kenny Graham, Vodafone R&D Group, has been a keen champion of femtocells in public areas for some time – coining the term metro-femto. He believes that the most difficult challenges for femtocell deployment have already been overcome. He classified femtocells into four groups and clearly believes all have a place in network deployment:
• Domestic
• Enterprise
• Public service areas (indoor hotspots)
• Metro Femto (Outdoor hotspot )
• Installing more antenna and equipment at existing cellsites, such as required for LTE or MIMO technologies, is constrained by physical and planning limits of cellsites. Metro femto can be deployed unobstrusively in the urban areas with peak traffic demand, providing high levels of capacity.

Looking forward to the LTE World Summit 2010

This month I will again be attending the LTE World Summit. I have already mentioned why I am looking forward to it. I also plan to cover the event in much more detail as I have done in the past.

I am also hosting a breakfast briefing session with my topic of interest being, "Using LTE to boost ARPU". I am interested if anyone has any opinions on this topic. I have started a discussion in the LTE Linkedin Group. Please follow this link if you want to post your ideas or follow the discussion (Sorry, you may have to become member of that group if you are not already a member)

As usual, I am always looking forward to meeting friends, colleagues, journalists, fellow bloggers and anyone and everyone. So if you are around then please do say hello.

LTE, Conformance Testing and GCF

According to Light Reading article, LSTI results indicate that most mobile operators are still in the very early stages of testing next-gen mobile broadband Long Term Evolution (LTE) and Evolved Packet Core (EPC) technology.

Meanwhile, the System Simulator manufacturers are going strong in their LTE Conformance testing.

Anritsu Corporation announced recently that it is the first test equipment vendor in the world to achieve GCF-approved test case validations for both LTE (Long Term Evolution) RF and protocol conformance testing.

Mobile terminal manufacturers must gain GCF approval to prove that their LTE terminals satisfy the 3GPP standards, meaning that there is increasing demand for an approved conformance test environment.

At the GCF CAG#22 meeting earlier last month, Anritsu successfully gained GCF approval for an industry-leading 12 RF test cases for its ME7873L RF Conformance Test System together with additional test cases for its ME7832L Protocol Conformance Test System.

Anite and Huawei demonstrated the first TD-LTE UE protocol conformance test cases. Anite and Huawei are working together to accelerate the process of TD-LTE technology for China Mobile’s World Expo.

The new TD-LTE tests build out Anite’s comprehensive portfolio for all leading 3GPP protocol technologies, from GSM through EDGE and WCDMA to the latest HSPA+ and LTE futures. Anite blends software-only host and target test solutions for 2G, 3G and LTE technologies that allow developers to adopt a total end-to-end solution for all wireless testing needs.

Starting next month, 7 layers will offer LTE testing services in three areas: regulatory compliance, certification, and operator-specific test cases.

Aeroflex Test Solutions and 7 layers have signed an agreement to provide LTE (Long Term Evolution) testing services in support of the commercialization of LTE mobile phone networks in Japan. Aeroflex will install its 7100 LTE Digital Radio Test Set in 7 layersA' laboratory in Yokohama, Japan, greatly expanding 7 layersA' LTE regulatory compliance testing services.

With advanced LTE test equipment and services conveniently located, Japanese UE (user equipment) manufacturers and network operators can speed up testing in advance of LTE rollout.

Some tests and logs from the UE Conformance Testing of Protocols are available on the 3G4G website here.

Dilbert Humour: Building Nationwide Wireless Network

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.
