Problems with 800MHz in UK and Spectrum to be auctioned

Even though 800MHz provides far better coverage than 2.1GHz (as shown above), it is going to be difficult to rollout LTE on 800MHz in the short term. The main reason being that there are quite a few other devices that use the frequencies or the frequencies neighbouring the 800MHz band and the interference may stop them working. A chart of the users is shown below.

It would be interesting to see when the rollouts in 800MHz would happen.

According to Ofcom, the following spectrum will be available in the UK:

• 250MHz of spectrum:
    • 2x30MHz paired at 800MHz
    • 2x70MHz paired at 2.6GHz
    • 50MHz unpaired at 2.6GHz
• (Also 2x15MHz of 1800MHz spectrum to be divested by EE)
• Starts to become available from Jan 2013
    • 800MHz expected to be available across whole of the UK by end of 2013
    • 2.6GHz across majority of UK by end of 2013 with remaining areas asap thereafter

All these topics were recently covered in a Cambridge Wireless event on Mobile Broadband SIG: Mobile Broadband in Rural Areas. The presentations are available here to view and download.
