TV White Space Allows Internet Connectivity To Reach Remote Areas
TV White spaces are unused frequency spaces deliberately put in place to ensure that channels that broadcast in analogue on allocated frequencies do not interfere with each other. Transmission through these TV White spaces can travel over long distances. They can go through barriers, including buildings and vegetation. In Kenya, as much as other parts of Africa TV White Space does have an excellent use. They can complement or extend the standard methods of Internet transmission, like cellular networks and WIFI.
The Wifi and cellular connection as a means of transmitting high-frequency internet connection need costly infrastructure to set up. These are still subject to interference and have limited reach. The TV white space tech, however, comes with its own set of challenges. The first downside of this technology is that the base stations needed to connect remote regions to town centres need to be set up as close as possible to the remote users. Another difficulty is the inconsistency as a result of lack of stable electricity.
The more poignant challenge has been the slow process it is taking convince governments to allow these frequencies, which has hitherto remained unused, to be converted and used for data connectivity.
