RF (Radio Frequency)
Comprising of Free to Air TV, Reticulated Satellite TV, DVD and Camera signals provide content around the home using televisions or other displays.
While the speculation is that RF will die out as a content format over the next 20 years in the face of TCPIP and Streaming Content over the Internet, RF is finding a resurgence in the US at present for the provision of Hi-Definition content.
A massive bandwidth is available to broadcasters in the VHF and UHF bands compared to the limited capacity available on the IF (Satellite) Band. A smart home will make use of plenty of RF (coax) cabling to locations such as display positions, AV equipment positions, FM Tuner positions and broadband router locations.
