 power drain. Adding other bands introduces additional switch paths that introduce insertion loss and poor isolation. The link budget gain of working at 700 MHz or 800 MHz is about 8 or 9 dB when compared to 1800 or 1900 MHz, and rather more when compared to 2600 MHz. This is a function of reduced propagation loss. Inbuilding penetration in particular should be notably better and should translate into improved coverage and/or higher average data throughput rates. However, these gains are academic if offset by RX and TX efficiency losses in the user's device. The form factor of an iPad or net book or lap top provides some extra space but this advantage can be offset by higher noise floors generated by display drivers or other proximate processor activity. Additionally, the decision has to be made as to whether the TV receiver should be expected to work simultaneously with broadband cellular. This would mean additional parallel processing Terrestrial Broadcast/Cellular Network Integration but more importantly would also require careful implementation to avoid desensitisation of the TV receiver by the LTE transmit path. Commercially, it would seem that this is a problem worth solving. Online connectivity viewed in parallel with broadcast content could provide the basis for a whole new genera- tion of interactive two-way content coupled with real-time peer-to-peer or peer-to-multipeer communication. Technically, this is a nontrivial challenge. The assumption is often made that this kind of dual functionality will become easier to deliver as software-defined radios and/or cognitive radios become more pervasive. Unfortunately, this is only partly true. Cellular transceivers today still route band-specific signals through band-specific filters and band specific power and low-noise amplifier compo- nents. All of these devices have individual matching components. Getting acceptable performance from a TV receiver integrated with a cellular multiband transceiver would probably also require discrete low-, mid- and high-band
