TV white space in London, UK: availability and maximum achievable capacity

The UK regulator Ofcom is holding an extensive pilot of TV white space (TVWS) technology in the UK. The Centre for Telecommunications Research, (CTR), London, is leading one of the largest trials within this pilot. On the basis of the UK´s TVWS framework and using the capabilities of the CTR regarding the pilot, how much white space is available in London and the capacity that can be achieved as an upper bound by aggregating all available white spaces are assessed.
