UK - Analysys Mason has published reports on the spectrum now held by the various operators

Analysys Mason has produced a short report on spectrum for telecommunications in the UK.

Key: BT; H3G trades as '3'; O₂; UKBB = UK Broadband; VF = Vodafone; EE = Everything Everywhere.

As they point out:

These results are only illustrative, but they serve to indicate that O2 and Vodafone both possess more valuable portfolios than a simple analysis of the total bandwidth would suggest. Conversely, BT and UK Broadband's portfolios may have a lower value relative to those of the four main MNOs than the number of MHz held would suggest.

It has also produced maps of the spectrum.
