Non-Line of Sight
Reliable, High-Speed Connectivity
The route that RF signals take is a DIRECT route between two points and the whole basis of Microwave / Wi-Fi technology, even with specific masts, is to gain the advantage of less infrastructure, easier installation and maintenance and better reliability than using cables (either copper or fibre). Although this is true, Microwave’s reliance on line of sight means that when obstacles occur (trees, hills, houses) additional infrastructure (masts, towers, relays, or multiple paths) is needed to circumvent these obstructions and to re-route the signals and this becomes much more difficult with mobile devices.
TV White Space, on the other hand, uses a frequency range commonly used for television and this lower frequency UHF signal enables penetration of obstacles so that the DIRECT route is supported by a non-line-of-sight capability. Obviously, this reduces infrastructure requirements (and therefore costs) but, apart from the interference factor, the electrical characteristics of TV White Space enable the signals travel further than traditional Microwave / Wi-Fi or Bluetooth (10 kilometres instead of 100 metres), again reducing costs.
