Ofcom consults on mobile data strategy

Ofcom, the Super regulator, is holding a consultation on its mobile data strategy, potentially looking as far forward as 2030.

Ofcom has recently sold off spectrum in the 800MHz and 2.6GHz bands and is looking to award spectrum in the 2.3GHz and 3.4GHz in the near future as well as opening up the use of TV whitespace and even the 700MHz band (which is currently used for DTT) which would mean moving the DTT band to 600MHz (and using MPEG-4 and DVB-T2 technologies).

This can be summarised in a table: -

  
Relative priority for potential releaseBands for consideration
Current priorities700 MHz, 2.3, 3.4 GHz, UHF white space
High1452-1492 MHz, 1980-2010 / 2170-2200 MHz (2 GHz MSS), 3.6-3.8 GHz, 5350-5470 MHz, 5725-5925 MHz
Medium-High2.7-2.9 GHz, 3.8-4.2 GHz
Medium450-470 MHz4, 470-694 MHz, 1350-1518 MHz

Some of these bands are in use and therefore current users will have to migrate off them or shared use is being considered.

Newer WiFi technologies make more use of the 5GHz band (Ofcom have noted the 2.4GHz band is already congested in many areas), however the 5GHz band would have to be extended (currently the bands are either licensed or lightly licensed as some of it is used for things like military radar).

Other parts of the spectrum would be expected to be used to extend mobile usages for 4G and 5G services.

The full statement (PDF) can be found here (it's 113 pages long).

Stakeholders can respond on-line.

Ofcom proposes to allow 4G on all 2G and 3G bands

Ofcom, the Super regulator, has opened a consultation to allow the liberalisation of all existing 2G and 3G bands so they can also be used for 4G (LTE) services.

This would mean O2 and Vodafone can refarm both their 900MHz 2G spectrum and their 2.1GHz 3G spectrum, EE (the combined entity of Orange and T-Mobile) have already started refarming of their 1800MHz spectrum, but they will be allowed to also refarm their 2.1GHz 3G spectrum. 3UK only have (currently) 2.1GHz 3G spectrum but will be able to refarm this and when EE transfer around 25% of their 1800MHz spectrum to 3UK they will also be allowed to use this for 4G (though this is not expected to happen until September 2013).

This is separate from any spectrum that is currently being auctioned (800MHz and 2.6GHz) though Ofcom has not yet announced who is bidding for what spectrum.

3UK have announced that when they launch 4G services, they will not differentiate on price between 4G and 3G services. The consultation is available here and interested stakeholders can respond on-line.

Ofcom delays auction of 800MHz and 2.6GHz (again)

Ofcom, the regulator that deals with broadcast, media, telecoms, radio and now the postal service has once again delayed the 800MHz and 2.6GHz spectrum auctions which now won't happen until at least the Q4 2012.

The 800MHz band will become available after the digital dividend (i.e. when the analogue television services are turned off in 2012), while the 2.6GHz band was reserved as an IMT-2000 (3G) band for future 3G services (or if the new 3G entrant i.e. 3UK failed and another network was set-up).

Both 800MHz and 2.6GHz are suitable for 3G services as existing phones should be able to use them (multiple band phones), they are also suitable for future mobile services such as LTE (Long Term Evolution) which is better known as 4G.

There is as more spectrum available in the 2.6GHz band than all existing 3G networks have already, however 2.6GHz has poor propogation characteristics as it is easily absorbed by buildings etc. 800MHz on the other hand has extremely good propogation characteristics (analogue TV signals work all over the UK) but can't transmit so much data. Thus 2.6GHz is suited to urban areas where there are large amounts of users and high data rates are required, while 800MHz is suited to rural areas as single sites can cover large areas.

This is also why all the legal wrangles have hindered the auction. All the 2G networks (O2, Vodafone, Orange and T-Mobile) got new 3G spectrum when the 3G licenses were awarded, while 3UK just got 3G spectrum. Recently Ofcom allowed the 2G networks to refarm their 2G spectrum for 3G use, giving existing 2G networks extra 3G spectrum.

Meanwhile Orange and T-Mobile combined (and had to give up some 2G spectrum in order to meet competition rules) to become Everything Everywhere.

3UK also felt aggrieved that it had a lack of spectrum as it didn't have any 2G spectrum in the first place.

Initially O2 and Vodafone had complained as they felt the 2.6GHz spectrum should have been given to existing 3G networks as it was a 3G band and threatened to take Ofcom to Judicial Review.

3UK also felt that existing operators should have their sub 1GHz spectrum capped (both O2 and Vodafone have spectrum in 900MHz for their 2G networks).

Court threats came and went and Ofcom held consultations and the spectrum auctions (that were originally meant to take place in 2007) got delayed and delayed again.

Then the Olympics were won by UK and by now broadcasters were using HD TV and even 3D TV and that meant remote broadcasting camera systems required much more spectrum than Ofcom had originally planned so they just allocated the unused 2.6GHz band and the (what would be now freed) 800MHz band for the broadcasters so neither could be made available at least until after the Olympics.

Ofcom is now planning a further consultation in late 2011 which will take at least 2 months which will then allow Ofcom to publish a statement in Summer 2012 and then an auction can follow later (i.e. not practically until Q4 2012). Ofcom actually released this information on Fri 7th Oct at 5pm (oddly when most news desks had closed for the day - Government departments tend to release bad news late on a Friday or just before public holidays - though Ofcom of course isn't a Government department but a Quango).

Various groups have seen this as hugely damaging to the UK economy as it will eave the UK well behind the rest of Europe (and the US) in terms of rolling out next generation 4G networks (LTE), though it's also a bit of a red herring as the UK networks haven't actually published plans to to rollout 4G networks any time soon (refarming 2G bands should provide considerable spectrum and greater 3G coverage). Though groups have claimed the economic loss to the UK could be around £730m.

As Ofcom have now reserved these bands for the Olympics they wouldn't realistically be available until 2013 anyway, so the new consultation and further auction delay won't materially affect actual rollouts based on these bands.

Things are not yet settled, there could still be legal battles and it's not going to be plain sailing. It's unfortunate that Ofcom (and thus the UK) was going to be one of the first countries to auction the 2.6GHz and 800MHz bands and now it's likely the UK will be one of the last to.

Ofcom opens Whitespace spectrum

Ofcom the super regulator that deals with regulation of broadcast media, radio and telecoms has made a statement about opening-up 'white space spectrum' and allow for devices to be deployed in a license exempt manner (in the UK there is no such thing as unlicensed spectrum and all transmission or reception equipment is covered by either a specific license or a 'blanket' license published by Ofcom and as long as the user/equipment abides by the conditions of the blanket license they don't need a specific license - bands like 2.4GHz which covers WiFi and Bluetooth devices are license exempt).

The equipment will have to connect to a central database (that Ofcom may actually subcontract to 3rd parties) which will note their geolocation and provide information about which frequencies are in use in that area. Ofcom may mandate a 'switch-off' mode such that if interference is detected in the area, white space devices may be forced to stop transmission.

This will be particularly suitable for rural areas as the 'white space' spectrum can be used to support wireless broadband and other services. This is significant as Ofcom are proposing that the TV bands can be used (as digital multiplexs use interleaved frequencies such that neighbouring transmitter sites don't interfere with each other) and TV bands have good propagation characteristics. Ofcom is also considering the UHF bands, though these may be more problematic longer term.

Ofcom also is considering use for WiFi like services (for localised high speed connectivity) and machine-to-machine communications which could cover things like meter reading.

Though Ofcom will have to consider European harmonisation so it make a while to implement (Ofcom is hoping for systems to be in operation by 2013), this is a bold step by Ofcom in making use of 'wasted' spectrum and being very proactive.

Ofcom will have to introduce an SI (Statutory Instrument) which is passed by Parliament to amend the WTA (Wireless Telegraphy Act) to make the spectrum license exempt.

FLO TV is dead, Long Live FLO Data?

As predicted Qualcomm have killed off their FLO TV service in the US which uses Qualcomm's Media FLO technology (you could buy an adapter for Android and other devices that was a radio receiver and some decode bits that allowed you to watch Media FLO channels on your phone).

What this means for the UK is still uncertain, as Qualcomm paid a considerable fee for a national license to run their Media FLO services.

Now Qualcomm are pushing to utilise the spectrum for data offload from existing mobile networks and this may be a winning strategy, though in Europe there's already spectrum coming available in 2.6GHz (a BUG chunk) as well as the old TV channels etc.

Qualcomm invested heavily in Media FLO technology and buying spectrum, which many believed was a white elephant and has been proved to be so. There's probably going to be a fire-sale of spectrum now.

T-Morange to build new network?

The new company that is the merged T-Mobile and Orange is thinking about building a brand new network in the UK. This will use equipment from Nokia Siemens Networks and Huawei and will support the frequency range from 900MHz to 2.6GHz (2600MHz).

This will allow the company to take advantage of new or refarmed spectrum that may become available in 2012, it will also allow rapid roll-out of new services based on GSM, UMTS (3G) and LTE (4G).

Neither T-Mobile nor Orange have any spectrum in 900MHz, but they're lobbying Ofcom that Vodafone and O2 should give up some of their spectrum when GSM spectrum can be used for 3G services. Currently the combined spectrum that T-Mobile and Orange own exceeds the license limitations for any single operator.

Ofcom have not yet auctioned 2.6GHz which initially was reserved for IMT-2000 use (the technical name for 3G) and due to various legal issues brought against Ofcom by the mobile operators wont be available now until at least 2012. There's likely to be a lot of interest in this band as it offers the potential high data rates (there's 190MHz of spectrum available). It's likely BT will bid for it as they can use it for WiMAX or other wireless broadband technology in rural areas and 3G services in urban areas as they've wanted to offer business mobile services for a while.

Sprint announced FemtoCell Airwave service

Sprint has announced its long awaited Airwave service using FemtoCells from Samsung (CDMA).

These are used in the home and utilise broadband for backhaul to Sprints network. When a user's Sprint mobile is in the vicinity of the cell it will use that instead of Sprint's main cell sites. Calls will be heavily discounted or free when in range of the femto cell.

More networks will adopt femto cells as they allow cheaper calls to be offered and high data rate services. The main issue with femto cells is they need licensed spectrum which is scarce in lots of countries.
