n. Wireless networking that transmits over the unused spaces in the TV spectrum.

New devices including smartphones, tablets, and computers that know how to detect unused spectrum can use it to transmit wireless broadband signals, also known as “WhiteFi” or “Super Wi-Fi.” These frequencies are especially useful because they can carry a lot of data over long distances and reach indoors.

"We are also exploring new technologies like ‘White-Fi’, which is an evolving technology," he said.

We have built WhiteFi, a UHF white space wireless network that adaptively configures itself to operate in the most efficient part of the available white spaces.

The "white" part of White-Fi comes from the so-called white space spectrum: the unused UHF and VHF bands between 54 and 790 MHz. Officially known as 802.11af, and sometimes also called Super WiFi, the main advantages of White-Fi over regular WiFi are that it can transmit over longer distances and it has better wall penetration, making it a good choice for rural wireless transmissions.
