Lack of LTE Devices, Still a Worry?

At this years Mobile World Congress, vendors were announcing LTE devices of all shapes and sizes. Besides modems, vendors showed netbooks and portable Wi-Fi hotspots that are compatible with LTE.

Perhaps the most impressive of the devices was the E398 modem unveiled by Huawei. The E398 is the world’s first triple-mode LTE modem compatible with all three major network standards: LTE, UMTS, and GSM. The triple-mode modem is based on Qualcomm's MDM9200TM chipset and will enable end users to seamlessly switch from LTE to either UMTS or GSM. The modem also supports multiple mainstream LTE frequencies.

The Huawei E398 modem will be initially launched in the world's first LTE/GSM shared network in Sweden operated by Net4Mobility, a joint infrastructure venture between Tele2 Sweden and Telenor Sweden.

Toshiba at the Mobile World Congress show this week showed off its Satellite T130 notebook PC with an integrated LTE network module from Sony Ericsson. During demonstrations at MWC the PC-maker demonstrated data download speeds of up to 16Mbps. This is significant as the PC is one of the first few with the high-speed connection option.

The AL600 from ZTE is being developed for the North American market and will operate in the 700MHz band, which Verizon will use in its upcoming network. The modem will also operate LTE in the 2.6GHz band,to cater for European operators. ZTE is also working on a portable Wi-Fi hotspot that lets users share an LTE connection using Wi-Fi.

Samsung’s new LTE netbook, bolstered with the presence of its own in-house designed LTE modem chipset Kalmia has been dubbed the world’s first LTE netbook PC. The device was also demonstrated at the MWC. Kalmia, which enables the development of a small form factor netbook with LTE capability, was brought to the fore by way of a live video streaming via the company’s own LTE network equipment on the Samsung netbook N150.

LG announced its LD100, a LTE data card, at CES in January. Anritsu demonstrated data throughput of up to 100 Mbps downlink and 50 Mbps uplink speeds on the LG device at MWC. LG also demonstrated handover between LTE and CDMA with their VD13 device. The company came up with a device for the Handover back in August, the M13, but the VD13 is an even slimmer device!

Perhaps less well known is that Ericsson is also working on integrating LTE into laptops and notebooks. The company is most known for its mobile networks, but it also sells modules for integrating mobile broadband into laptops and netbooks. Ericsson's module will operate in multiple frequency bands for LTE and HSPA. But it won't start shipping the module until LTE has become a "mass market" technology, and that won't happen until the beginning of 2012, according to Ericsson.

Huawei and ZTE will ship its modems -- the E398 and the AL600 or AL620, respectively -- by the end of the year. Samsung promises to ship its modem during the first half of 2010, according to a spokesman. But operators only expect to get their hands on a limited number of modems, with volume shipments starting in the beginning of 2011, according to Magnus Zetterberg, CTO at Telenor Sweden.

One of the things vendors have to think about more about when designing products for LTE is which frequencies they will operate on as operators will be using various frequency bands for LTE. LTE pioneers Verizon Wireless, NTT DoCoMo and TeliaSonera will all use different frequency bands for their respective LTE network. So for roaming in the U.S, Japan and Europe to work, modems will have to support 700MHz, 2100MHz and 2600MHz with more bands likely to be needed in the future.

With the GSMA focusing its efforts on roaming for LTE, this should help to encourage device manufacturers that there is sufficient momentum and demand for LTE devices. It should also make operators that think that LTE is not ready, think again...

Has Telefonica Been Lagging a Little too far Behind with LTE?

Telefonica has become the latest global operator to LTE trials and has has selected six vendors to launch test projects in six different countries in preparation of rolling out LTE-based networks

Alcatel-Lucent, Ericsson and Nokia Siemens Networks will represent Europe while Japanese vendor NEC and Chinese vendors Huawei and ZTE will fill out the remaining three slots making the selection of vendors quite the East-West mix.

Telefonica isn’t limiting its trials to Europe. In addition to building networks in Spain, the UK, Germany and the Czech Republic, Telefonica will also run trials in Argentina and Brazil, interesting as they have only recently rolled out HSPA and it seemed to most that LTE is still a really long way off. Each vendor will be given a different country and will deploy its e-Node B base stations this year for the six-month testing period. Telefonica also said that the trials won’t necessarily be limited to six vendors or six countries. It will be open to other suppliers, which could leave the door open to players like Fujitsu and Motorola of Telefonica does indeed decide to cast the net wider.

Telefonica has no projected timeline for deploying LTE and in most of its markets doesn’t even own free spectrum. In fact, Telefonica said that the results of the trials will largely inform its LTE rollout strategy rather than the other way around.

Telefonica is certainly not a leader in the the market, an example of this was when it was named and shamed in the UK for not meeting the regulator's requirement of having 80% coverage in the UK. It is more likely that they just want to have a strategy in place for when the handsets and devices are ready (leaving the voice over LTE problem for everyone else to sort out?) This could be years away, or if other operators such as Verizon Wireless continue to push for handsets and devices then this "critical mass" that needs to be reached for the followers in the industry to start deploying LTE, may be sooner than we all think.

The announcements of new devices from LG, Samsung and Nokia has probably made executives at Telefonica sit up and take notice of how the Industry is rallying around LTE - and that their competitors are perhaps a little too far ahead of them than they would like.

Feedback from the LTE Customer Consultation Day

Taking part in the LTE customer consultation day, were some of the top vendors including Ericsson, Huawei, NSN, Motorola and others including picoChip, Freescale, Signalion and Rohde & Schwarz. They attended the consultation day, as they really wanted to get involved in the LTE conferences in 2010 and to get their input into the agenda.

With regards to content, the LTE business model that the most important topic that they highlighted. Now that a lot of the technical details have been ironed, operators have committed to LTE the attention has been turned to the business model and how can operators monetise LTE.

Can we really still have flat rate data plans? We've seen the cost/revenue divergence diagram a hundred times at various conferences, but has anyone really come up with an answer as to how operators need to address this divergence and try to take control of the network? With LTE operators are able to differentiate services and charge accordingly to the customer's QoS requirements, but there is no clear indication that operators are willing to change the their pricing models.

The application and service providers are a key new entrant into the market and there needs to be a discussion on how operators can profit more from these applications and services - will LTE make operators think differently?

Who are we going to be selling LTE to beyond the average user? LTE would be attractive to vertical markets such as the public safety organisations, the healthcare industry and I as mentioned in one of my earlier blogs; the car industry.

These are certainly areas to explore and it will be interesting to get feedback from different markets, not involved in the telecommunications industry and hear about what they they think of the future of mobile broadband.

A Day at the Huawei Campus in Shen Zhen

My colleagues and I at Informa were invited to visit the Huawei campus in Shen Zhen last week, the day before the LTE Asia conference which took place in Hong Kong to discuss their plans for the future with LTE being central to their growth prospects.

Huawei has been an early investor in LTE and it is clear that they have been thinking ahead. Huawei launched their All-IP based FMC solutions back in 2006. To maintain a leadership position in All-IP FMC, they established an integrated core network product line, with 6,000 engineers engaged in R&D supported by a service team of 2,000 professionals around the globe dedicated to providing customers with all-round consultation, planning, delivery maintenance and training services.

Its no wonder that the campus in Shen Zhen has grown to include an administration centre, marketing centre, R&D centre, testing centre, training centre, exhibition hall, logistics and manufacturing centre and a staff condominium. Just to cater for all the staff on the campus requires a total of 9 canteens providing food for 30,000 employees, catering for all tastes and cultures. What was clear during our tour of the facilities was that Huawei does not do things by halves and why would they when they serve 36 of the world’s top 50 operators?

Huawei is a relatively young company they are continuing to gain steady recognition and acceptance from operators in more developed telecommunications markets. Although I have heard rumors about their integrity as well as to product quality ranging from the absurd to the bizarre, this has clearly not deterred their customers. To a significant degree, Huawei’s early and ongoing experience with successful deployments under the constraints of emerging markets has helped to win contracts with the now price conscious operators in most developed markets. This includes TELUS and Bell Canada’s LTE-oriented HSPA network as well as winning the world’s first LTE contract with TeliaSonera along with Ericsson.

Operators are increasingly looking at vendors that have a comprehensive, end-to-end portfolio of products and solutions for LTE. Huawei’s strength lies in the full breadth of their comprehensive, scalable and interoperable offerings for customers and so it was no surprise that Huawei was recently recognized by BusinessWeek as one of the world’s most influential companies.

T-Mobile Focusing on LTE Performance & QoS

T-Mobile has carried out LTE trials with Huawei base stations and the first test of multi-user broadband services with mobility on a Next Generation Mobile Network (NGMN) using LTE in the city of Innsbruck in West Austria.

The project is the largest European test network covering 60 radio cells and has been running since the beginning of July 2009. The focus of this test network was to gain customer experience insights as well as technology testing and verification. In particular, T-Mobile is focusing on aspects such as quality, stability and reliability in a variety of environments ranging from the inner city to highways in and around Innsbruck.

T-Mobile was the first company to successfully demonstrate NGMN capabilities under real life conditions and was able to achieve data rates of up to 150 Mbit/s and during a showcase in Vienna, Austria earlier this year, T-Mobile also achieved a speed of over 130 Mbit/s over the air with four modems registered in a cell at the same time.

Clearly, superior customer experience is at the heart of what T-Mo wants to achieve with its LTE network, especially in Austria, a country that is at the leading edge of European mobile data usage, with market leader Mobilkom Austria deriving one third of its revenues from mobile broadband services.

Will Huawei Make Any Headway in the US LTE Market?

It is clear that Huawei and Ericsson have been stumping the most contracts for LTE. Huawei recently teamed up with Vodafone Germany to test LTE in the digital dividend band and boasts contracts with TeliaSonera and Telenor. Rival to vofafone Germany, E-Plus also has a pilot, working with Ericsson, in the same digital dividend band.

Huawei's next target seems to be a tier 1 operator in te USA, which unlike Ericsson (with Verizon Wireless), Huawei doesn't have. It has already signed a deal with the cable company Cox Communications for a 3G network, but its the LTE contacts Huawei is after. Huawei recently opened an LTE lab in Plano, Texas and they are hoping to be in the running to become a supplier to AT&T for its LTE network although that deal is unlikely to materialize for at least another year.

Huawei's price competitieveness is putting pressure on vendors such as NSN and Alcatel-Lucent. Its seems as if its only a matter of time that before Huawei makes an impact on the US market.

Is Vodafone Looking at a Mass LTE Deployment in Germany?

With the announcement that Vodafone Germany will work in cooperation with Huawei to test LTE in the digital dividend bands (790-862MHz), wha is interesting is that Vodafone may be planning to deploy LTE in rural areas.

Is has been suggested by many operators, that LTE will initially only be deployed in high density urban areas or hotspots to help ease conjestion. The test that will be carried out by Vodafone and Huawei will be to assess the ability of LTE to provide wireless broadband coverage to rural and urban areas. The test will also look to prove LTE's compatibility with adjacent technologies such as digital TV and digital radio.

This announcement suggests that Vodafone is potentially looking to deploy LTE on a much larger scale if the test results are positive.

Is HSPA+ a Distraction or a Real Stepping Stone on the Path to LTE?

HSPA+ is gaining momentum as a stepping stone on the path to LTE. The Japanese operator eMobile has just announced that it has launched HSPA+ services in the country, using kit supplied by Huawei.

eMobile is promising mobile data speeds up to 21.6Mbps on the downlink and covers cities such as Hokkaido, Sendai, Niigata, Hiroshima, Fukuoka and Nagasaki. The service provider will offer internet access, streaming media and VoIP and will connect the end user with a Huawei supplied data card.

So why have certain operators opted for HSPA+ instead of migrating directly to LTE? NTT DoCoMo was the first operator in the world to launch W-CDMA and the network is not due an upgrade. W-CDMA was deployed by Softback in 2003 and Other operators such as Softbank deployed in 2003 and eMobile only launched its 3G service in 2007. These operators cannot justify a major overhaul of the network to the shareholders, where as DoCoMo can say that that they have made a good return on their investment and its time to reinvest for the future with LTE.

eMobile customers have reported congestion problems in some locations at peak times and the problems are only going to get worse. HSPA+ works out as a cheaper option for operator that needs to upgrade its network in order to cope with the ever increasing amount of traffic. LTE will just have to wait for its turn in these sorts of cases.
