Will LTE Signal the End of GSM?

At the end of last year NTT DoCoMo launched their LTE network. They had announced back in May, at the LTE World Summit that they have a roadmap in place to migrate remaining customers on thier 2G network to 3G and LTE and plan to swich off the 2G network within 2 years. So we're looking at a switch off date of May 2012. This isn't as agressive and anmitious as it seems, as DoCoMo has an unusually high proportion of its subscrbers already on 3G. Coupled with the fact that DoCoMo uses the rather niche PDC technology for its 2G network, you can understand why they want to part ways with it.

So why aren't other mobile operators in mature markets as keen as NTT DoCoMo is on this strategy? Surely the cost of running a 2G, 3G and LTE network is not sustainable given declining revenues? The first reason is that no operator will switch of their GSM network until there is complete ubiquity of at least 3G. Secondly, GSM provides an excellent voice service and in markets such as the UK where customer bases are polarised either towards being very smartphone savy or just wanting a very basic mobile phone to make phone calls. In this case why should UK opeators go to the effort of migrating everyone to 3G/LTE when 65% of their revenue still comes from voice and the GSM network is so reliable? The third reason is that even though the difference in QoS between EGDE and 3G is considerable, EDGE is still good enough for basic web browsing etc (remember the first iPhone?)

If we start to see 99% coverage requirements for 3G as they have in France, then this will make the case for operators to commence a roadmap for 2G switch off. This however will not happen overnight. Coverage requirements such as the example in France can only really come in to place after the regulators have re-farmed the 900MHz band for UMTS or the 800MHz digital dividend band for LTE - or as in France's case, both.

Operators seem to be resigned to the fact that for now they will have to operator 3 different networks (4 if they operate a series of WiFi hotspots!). In this situation optimising traffic-flows across different networks and having the right policies in place for managing capacity effectively is essential.

If DoCoMo is successful then operators may think again, but for now is seems that GSM still has a long life ahead.

Will India Get LTE? (Part 2)

I blogged a few weeks ago about whether India would get LTE and I had the opportunity to meet with a few of the the indian regulators at the LTE Asia conference last week.

They confirmed that that auction would go ahead this year on December the 7th, but since there have been so many delays and setbacks already, who knows... The WCDMA auction kicks off first, with the CDMA and WiMAX auctions taking palce 2 days later. I was also told that the FDD spectrum will only be allowed for 3G networks and TDD will likewise be for WiMAX deployments only. The TDD spectrum is expected to sell for a much lower price than FDD spectrum - no surprises there.

Its does indeed seem that the Indian regulators are keen on WiMAX and this is simply down to the infrastructure cost. Currently in India, the ARPU from a subscriber in the cities is $4 and just $2.50 in rural areas! Although the WCDMA networks are likely to be upgraded to LTE at some point, can LTE ever be affordable for India?

CSL Crystal Clear About Their LTE Strategy

Tarek Robbiati, the CEO of CSL opening the LTE Asia conference in Hong Kong last week. The problem: 3G was always going to be disadvantaged against 2G spectrum bands of 900 and 1800 MHz. It set the scene for the rest of the conference, where spectrum was the topic discussed the most.

CSL will be launching UMTS900 and are looking to have a LTE ready network, by leveraging the SDR capabilities of ZTE. SDR (Software Defined radio) is a topic that has been talked about for years, but always looked like something that was ahead of its time. CSL have put in the time and the investment to make it work for them. They want their equipment to be software upgradable, so that they can quickly and smoothly to improve their time to market with LTE and save on costs.

CSL owns spectrum in the 900, 1800, 2100 and 2600MHz bands (the latter acquired in the recent auctions in 2009). They are going to start by addressing UMTS coverage by deploying it in the 900MHz band. LTE is then going to be rolled out across multiple bands! Whilst some operators are mulling over what band they will choose for an LTE deployment, Tarek simply stated that thay will use whatever spectrum they have and as much as they can for LTE. LTE will therefore be deployed in all four of the spectrum bands that they own.

Concerns were raised about standards that still need to be defined for voice services and the need for devices, but all of the CSL employees at the conference could not praise the Hong Kong regulator OFTA enough for the way the recent spectrum auction was managed. They must be over the moon with all of the spectrum they have and what they will be able to achieve with it.

Will India Get LTE?

The spectrum auctions in India were postponed once again a couple of weeks ago. The Empowered Group of Ministers (EGoM) was scheduled to convene on 31 July but the meeting had to be delayed because one of its members was not be able to attend.

The EGoM formed on 13 July has been tasked with resolving a number of issues that have hampered the government's 3G plans, including how much spectrum to auction, the reserve price for 3G and WiMAX bandwidth, and annual spectrum charges. The panel must also decide how many companies will be allowed to operate mobile services in each of India's 22 telecom circles, and it must rule on administrative and auctioneer fees.

Still, both of India's state-run mobile operators BSNL and MTNL have already launched commercial 3G services after rules set out in August 2008 guaranteed the two operators would have access to spectrum. In April reports claimed BSNL had signed up between 8,000 and 10,000 3G customers, while MTNL in June set its sights on adding between 200,000 and 300,000 subscribers during the first year of operations according to Total Telecom. The two operators will be required to match the winning bids made for bandwidth when the 3G auction finally taes place. On the whole, it seems positive for LTE in this region with BSNL and MTNL likely to go on and migrate their 3G networks to LTE. So does India need WiMAX as well?

Even as the policy for auctioning spectrum for 3G mobile services is yet to be finalised, the Department of Telecom is already thinking about the introduction of LTE. The DoT has taken a view that each operator offering 4G technologies should be given at least 10 MHz spectrum compared to just 5 MHz for 3G services.

LTE may therefore come in India in at the 2.1 GHz band, as 2.5 GHz is mostly used for satellite-based networks. According to industry experts, the DoT is on the right track by identifying at least 10 MHz for LTE. But it has also earmarked 20 MHz for WiMAX.

Denmark Planning Auction of LTE Radio Spectrum

­Denmark is to hold a consultation on auctioning off radio spectrum in the 2.5GHz bands. The Ministry for Science, Technology and Innovation (National IT and Telecom Agency) said that 205MHz of spectrum will be auctioned in total: 190MHz in the 2.5GHz band (2500-2690MHz) and 15MHz in the 2010MHz band (2010-2025MHz).

The spectrum, which will be auctioned on a national basis, is suitable for providing 4G wireless broadband services based on standards such as LTE. However, it may also be attractive for other uses such as mobile TV or wireless cameras.


The licences granted to the winning bidders will allow them to deploy their own choice of technology (provided it does not cause interference to other spectrum users) and offer any type of service.

The auction is expected to take place in the first quarter of 2010 and will be conducted electronically, with participants submitting their bids via a secure Internet connection. Stakeholders are invited to comment on the proposals by responding to the consultation before 15 September 2009.
