LTE news roundup for April 2012

Photo of Mark HeathThere have been a number of interesting announcements in the last few weeks related to LTE.

Firstly, NTT DoCoMo in Japan has announced that the number of subscribers to its LTE Xi service reached two million on March 18 2012 – an increase of one million subscribers since December 24 2011. This growth has been encouraged by the introduction of the first Xi-compatible smartphones in November 2011. NTT DoCoMo launched its LTE service on December 24 2010. It is particularly interesting to see the recent increased pace in subscriber growth. It has taken NTT DoCoMo less than three months to reach its two-millionth customer, compared with about a year for its one-millionth customer. This progress looks very promising.

Following my recent positive review of the LTE-capable iPad 3, I’m pleased to see that iPad 3 sales have got off to a great start. Apple has announced that 3 million iPad 3 units were sold in the first three days after its launch on March 16 2012. However, it has not been all plain sailing for the LTE-equipped iPad. The iPad 3 does not support all frequency bands associated with LTE across the world, restricting its use to North America.  The iPad 3 only supports LTE using 700MHz and 2100MHz frequency bands. Apple’s website now states, “4G LTE is supported only on AT&T and Verizon networks in the U.S. and on Bell, Rogers, and Telus networks in Canada”. In Australia, Apple has been forced to offer refunds to customers who had mistakingly purchased the iPad 3 believing that it would work with Telstra’s LTE network.

The rapid take-up of the iPad 3 will help to drive traffic volumes on LTE networks in the USA. As a sign that US operators are anticipating significant growth in mobile traffic, it has been widely reported that Verizon (in an FCC filing) has predicted a more than 20-fold increase in LTE data traffic from the end of 2011 to the end of 2015.

I’ve written before about how some operators are trying to encourage the substitution of fixed broadband services using LTE. For example, Vodafone Germany has been seeking to migrate its DSL customers to LTE. Up until recently, US operators have preferred to position LTE  services as a complement to fixed broadband services. In March 2012, Verizon made the notable step of unveilling its new HomeFusion antenna product, which is more clearly aimed at customers wanting to displace fixed broadband services. The HomeFusion antenna, which is priced at USD200, has to be installed on the outside of a customer’s home (by Verizon). Verizon hopes to offer HomeFusion in all of its LTE  markets by the end of 2012. The performance of its LTE network, with downlink speeds of 5-12Mbps and uplink speeds of 2-5Mbps, will be attractive to rural customers currently experiencing patchy DSL services. Verizon charges USD60, USD90 and USD120 for its HomeFusion services with monthly data allowances of 10GB, 20GB and 30GB respectively. While these are generally more expensive (and have lower monthly allowances) than many fixed broadband services, they are likely to appeal to customers unable to get decent fixed network speeds.

USA pulls ahead of Europe with LTE

Photograph of Alastair BrydonIt doesn’t seem long ago that I remember looking across the Atlantic with pride as Europe forged ahead with the deployment of GSM systems, while the USA struggled to keep up with a disparate array of mobile network standards. Not anymore. Last week T-Mobile became the last of the four US national mobile operators to announce its intention to launch LTE services in 2013, while the plans for many European network operators remain unclear.

We have commented previously on the early launch of LTE services in the USA and indeed the plans of both AT&T Mobility and Sprint Nextel to launch LTE-Advanced services in the USA in 2013.

In January 2012, Sprint stated its intention to launch LTE in Dallas, Atlanta, Houston and San Antonio in the first half of 2012.

Now T-Mobile has announced the launch of LTE services in 2013, as part of a USD4billion network modernisation programme. Part of the plan is to refarm existing HSPA+ services to 1900MHz, which has previously been used only to support GSM. This releases the 1700MHz band for LTE and has the added benefit that T-Mobile will then be in a position to support the Apple iPhone with HSPA+ services. Currently T-Mobile is the only one of the big four US operators that is unable to support the iPhone, because its HSPA+ services operate in unsupported bands. With rumours that the imminent iPad3 will support LTE, there was a danger of T-Mobile being seriously left behind by its competitors.

As the USA presses ahead with LTE, the gap between the USA and Europe appears to be widening. France, Italy, Spain and the UK are all currently without LTE networks. The UK doesn’t even have a firm date for the auction of new spectrum for LTE, let alone network operator plans to deploy commercial LTE services. As LTE networks and devices become increasingly prevalent around the world, countries and individual network operators without it are going to look increasingly like the poor relations.

UK spectrum auction will shape mobile industry for many years to come

Photograph of Alastair BrydonThe forthcoming auction of 800MHz and 2.6GHz spectrum, and the associated licence conditions, will have a profound impact on the mobile industry in the UK. In its latest consultation and proposals, Ofcom highlights that the auction is “likely to be the last significant opportunity to obtain prime mobile spectrum for many years” and that the distribution of spectrum after the auction “is therefore likely to shape the competitiveness of the mobile sector for at least the next decade”.

It is crucial that the auction process leads to the cultivation of top quality coverage, high speed data and service innovation. The last major auction of mobile spectrum in the UK, held in 2000, failed to provide these and it could be argued that the UK networks have done little more than tread water for the last ten years. As we have commented previously, 3G coverage is, even now, much worse than 2G coverage.

Ofcom is of the view that the UK needs at least four “credible national wholesalers”, by which it means four network operators with spectrum portfolios that are strong enough to offer competitive services nationally, with regard to capacity, quality of coverage, peak data rates (immediately after the auction) and availability of LTE (immediately after the auction).

Ofcom is of the view that this level of competition is essential to achieve low prices, high quality coverage and innovation of services. However, experience of 3G shows that, while competition can help to reduce prices, it does not necessarily enhance coverage (particularly in rural areas) or increase innovation. It is striking how similar all of the UK operators are, in terms of their pricing and services, and I have lost count of the number of overseas visitors who have expressed their surprise at the limited coverage and quality of the UK networks, compared with other markets.

So how do we ensure that these important points are addressed this time, given that competition alone is not enough? Ofcom is still evaluating the options, but it is good to see that at least some aspects are being addressed. In his recent post, Mark Heath has already talked about the positive introduction of demanding coverage targets, for at least one of the licences. However, another important issue is the cultivation of new ideas and service innovation. One of the problems with relying on the established industry players is that they will tend to do things the way they have always done them.

Ofcom already anticipates that three of the “credible national wholesalers” will be Everything Everywhere, Telefónica O2 and Vodafone. It is good that Ofcom intends to reserve spectrum to ensure that a fourth player (either H3G or a new entrant) has a strong enough portfolio to compete with these long-established players. However, personally I would like to see some new blood in the industry, to inject some new ideas and different approaches.

Over ten years ago, during the preparation for the 3G spectrum auction, I worked closely with the SpectrumCo consortium, led by Virgin. The consortium worked with telecom experts and a wide variety of major retail brands to develop a number of radical new ideas, including:

  • a wholesale operator with a number of strongly branded MVNOs
  • ambitious roll out plans to provide high-quality coverage as soon as possible
  • an exciting vision for the future of terminals and the mobile Internet.

As it turned out, the high cost of the licences deterred many new entrants, including SpectrumCo, during the bidding process, so we ended up with the existing players plus H3G, all of which paid huge sums. H3G focused primarily on pricing innovation (e.g. bigger bundles) rather than innovation in services or business model.

In retrospect, the technology of the day may not have been ready for some of the exciting ideas and service concepts promoted by Virgin and its partners. However, ten years on, the pieces of the jigsaw are coming into place and the availability of high speed data and advanced smartphones could now make these visionary ideas a reality. Early 3G technology was unable to deliver high data rates, but LTE is fully able to do so, especially when bolstered by microcells, femtocells, WiFi and smart antennas. Also, we anticipate that exciting new mobile devices, such as the forthcoming iPad 3 and iPhone 5, will support LTE. Furthermore, although there is a substantial amount of new spectrum on offer, the economic environment is such that the cost of the licences may be substantially lower than 3G.

Hopefully this exciting opportunity will encourage new players to enter the UK mobile market, either on their own or perhaps in partnership with H3G. It would be good to see some of the ideas of ten years ago finally come to fruition.
