Detailed results from the Wi-Fi offload model
Figure B .25 shows a breakdown of the consumer and producer surplus from Wi-Fi offload, and Figure B .26 shows the results of the sensitivity analysis. The base case assumes that 95% of indoor traffic will be offloaded by 2021, while Scenario 2 assumes a lower estimate of 75%.

Broadcast TV model
We have built a new model to calculate the consumer and producer surplus from DTT and DTH satellite broadcasting. We have not considered analogue terrestrial broadcasting (since this will cease before the end of 2012) or cable TV (since this does not involve the use of radio spectrum). We have, however, included BT Vision Internet Protocol (IP) TV households in our consumer surplus calculation, since these subscribers still receive broadcast TV channels via DTT. Thus, two main TV segments are considered:
DTT (Freeview)136
DTH comprising free DTH (Freesat, including Freesat from Sky) and pay DTH (Sky).
The structures of the approaches used to estimate the consumer surplus from DTT and DTH are shown below in Figure B .27 and Figure B .28.

Key: HH = households, MUX = Multiplex

The structures of the approaches used to estimate the producer surplus from DTT and DTH are shown below in Figure B .29 and Figure B .30.
