A system is described for distributing over the air (OTA) channels within buildings and homes. The system can implement one or more active multi-mode antennas for improved performance and reliability. The system can be configured as a mesh network where multiple nodes are distributed to improve the probability of channel capture across the VHF and UHF frequencies used for over the air TV distribution. A node consists of a beam steering antenna that operates at the VHF and UHF frequencies for TV signal reception, a receiver and demodulation circuit, a transcoder to convert the received information for re-distribution, and a transceiver capable of operation at a secondary frequency band for use in re-distributing the information to communication devices in proximity of the node. The secondary frequency band can be the common WLAN (Wireless Local Area Network) system such as Wi-Fi, with the Wi-Fi transceiver also containing beam steering antennas for improved in-building propagation of the re-distributed information.

RF system for distribution of over the air content for in-building applications

An antenna system for use with a media device is provided. The antenna system includes a multi-mode active antenna configurable to operate in a plurality of modes. Each mode of the plurality of has a distinct radiation pattern. The antenna system includes a supplemental tuner that is separate from a primary tuner associated with the media device. The antenna system includes a switching device movable between at least two positions to selectively couple the active antenna to the supplemental tuner. When the switching device is in a first position, the active antenna is coupled to the supplemental tuner. When the switching device is in a second position, the active antenna is coupled to the media device.

Host-independent VHF-UHF active antenna system

Example aspects of the present disclosure are directed to front end modules for use in communication systems. In one example aspect, a front end module can include a receive path. The receive path can include a low noise amplifier. The receive path can include an analog to digital converter (ADC) circuit operable to receive an analog signal from the low noise amplifier and convert the analog signal to a digital RF receive signal. The receive path can include an ADC post processing circuit operable to process the digital RF receive signal in the digital domain. The front end module can include a transmit path. The transmit path can include a digital to analog converter circuit operable to convert the digital RF transmit signal to an analog RF transmit signal. The transmit path can include a power amplifier.
