White Fi

White Fi is a term used to denote low-cost devices that deliver long range wireless connectivity to the internet over white spaces of spectrum between the TV channels.

White Fi is designed in such a way that it senses the frequency usage in his environment. This sensing information is shared with other devices in the area to improve the sensing information. One of the most difficult questions in the development of the devices is the correct sensing of wireless microphones which also make use of the white spaces in the TV bands. Interference to the wireless microphones will have to be prevented.
