The short-wave relay station, which will be built in the desert's Arava Valley, will have 16 transmitters with a broadcast capacity of 500 kilowatts each, making it the world's second-largest Voice of America transmitter, after one outside Manila.
Our broadcast offer on Freeview and YouView will be slightly different owing to long-standing broadcast capacity constraints.
The interim broadcast capacity for CBBC HD will have less coverage in the UK than the existing capacity.
Here, we do not consider the general broadcast capacity region but rather focus on maximizing the bottleneck link rates.
"In a broadcast capacity, satellites are by far the most efficient infrastructure you can have," says Kidd. "But in point-to-point, a satellite does not have a lot of capacity; you have to spread the capacity cost over a smaller number of subscribers, making the services more expensive".
After the Olympics period, we'll be returning things back to normal – whilst CBeebies HD and BBC Four HD will also be moving to a different slot of broadcast capacity from where they are now, and so may require a retune, for the majority there should be no material impact from the current Freeview reception of these channels.

We present both an analytical evaluation of the broadcast throughput capacity that can be achieved by using the VBN mechanism and a simulative analysis based on the IEEE 802.11p CSMA/CA MAC protocol, standardized for VANET.
Dirty paper coding (DPC) is non-causal and thus impractical, although it achieves the MIMO broadcast channel capacity [14].
An achievable rate region with structural properties satisfied by the two-user additive white Gaussian noise broadcast channel capacity region is assumed.
In [2] Liu and Shamai propose a more information-theoretic approach using the enhancement concept, originally presented by Weingarten et al. [7], as a tool for the characterization of the MIMO Gaussian broadcast channel capacity.
Dirty paper coding (DPC) was first proposed in [11] to achieve broadcast channel capacity for single-cell MIMO systems, and it was extended to solve the non-convex sum-rate maximization problem for multicell systems [12].
