@Gideon and @JetSetJim. Agree 100pct.
The 800MHz band has just been released by Ofcom for mobile broadband - LTE most likely. This and the GSM900 spectrum will NOT give high speed or very large capacity. It is needed for universal LTE coverage without inflating the cost, while the 1800, 2100 and 2600 MHz spectrum will ensure needed capacity and speed in populated areas.
The GSM900 will be phased out over time and Ofcom will of course modify the licenses for LTE (or some other 4G tech) as needed.
LTE tech will be released very soon into the market - faster than spectrum in the UK can be reallocated ? - and most new investments will likely be for 4G solutions.
It would - IMHO - be much better to allocate/auction the 800MHz band and even refarmed GSM900 spectrum - as a percent of total capacity and not as physical frequencies bands.
If - say - three telcos (A, B, C) should share the 800MHz band, each should not bid for 2 x 10 MHz, but for 33% of the total 2 x 30 MHz capacity. This will give a much more efficient utilisation of the limited and expensive bandwidth. If a particular 800MHz cell has few active customer from telco A and C, but many from B, then telco B customers can use the unused bandwidth of A and C for higher speed and more capacity.
Telco A,B and C will and must still compete for customers. But they will share the operation the physical network or outsource the net-operation to a third party.
