Patent ID: 7813451

Claim:
An apparatus for frequency shifting without any protocol conversion between a wireless signal in a wireless frequency band carried by a wireless medium and a wired signal in a wired frequency band carried by a wired medium, said apparatus comprising: an antenna for receiving and transmitting the wireless signal; a wiring connector for connecting to the wired medium; a down frequency shifter for down frequency shifting a signal from the wireless frequency band to the wired frequency band; an up frequency shifter for up frequency shifting of a signal from the wired frequency band to the wireless frequency band; an RF switch coupled between said antenna, said down frequency shifter and said up frequency shifter, said RF switch having first and second states, wherein in the first state said antenna is coupled to said down frequency shifter and in the second state said antenna is coupled to said up frequency shifter; and a wired frequency band switch coupled between said wiring connector, said down frequency shifter and said up frequency shifter, said wired frequency band switch having first and second states, wherein in the first state said wiring connector is coupled to said down frequency shifter and in the second state said connector is coupled to said up frequency shifter; wherein said apparatus is switchable into distinct first and second states, wherein in the first state of said apparatus, said RF switch is in its said first state and said wired frequency band switch is in its said first state for receiving the wireless signal from the antenna, down frequency shifting the wireless signal and transmitting the shifted wireless signal to the wiring connector; and wherein in the second state of said apparatus, said RF switch is in its said second state and said wired frequency band switch is in its said second state for receiving the frequency shifted wireless signal from said wiring connector, up frequency shifting to reconstruct the wireless signal and transmitting the wireless signal to the antenna.
