*132. "Another missing infrastructure link for digital terrestrial TV is a return path for interactive services - a capability already provided on satellite, DSL and cable networks."* That's because it's a broadcast, not a peer-to-peer network. And this "return path" would be - oh yes, the internet.
Not necessarily, DVB-RCS and DVB-RCT are two return channel standards issued by DVB recently offering Return Channels via Satellite and Terrestrial transmissions
*101 ... higher mobile termination rates applied to T-Mobile and Orange have provided some compensation for the higher costs associated with poorer propagation properties.* Or, in English, "T-Mobile/Virgin and Orange (1800Mhz) phones don't work as well as Vodafone and O2 (900 MHz) ones, but cost more to call. "
I think they mean that to get similar coverage, more base stations are needed, which incurs a greater cost.
