Abstract:
1. A wireless enhancer comprising a first antenna for receiving an incoming signal; a receiver sub-system that amplifies and converts the incoming signal from the first antenna to a first predetermined frequency band; a demodulator coupled to the receiver sub-system for demodulating the converted signal, and detecting timing information thereof; a transmitter sub-system operable with the receiver sub-system that converts the signal from the receiver sub-system to a second predetermined frequency band and amplifies the signal; a second antenna for further transmitting the amplified signal from the transmitter subsystem; and a switch matrix that controls connection switching among the first antenna, the second antenna, the transmitter sub-system, and the receiver sub-system, wherein the connection switching of the switch matrix is made based on the timing information detected by the demodulator and based on whether the incoming signal comes from a terminal or a base transceiver station (BTS) of a wireless communication network, wherein the switch matrix is a transfer switch with four ports, the first port being connectable to the receiver sub-system, the second port being connectable to the transmitter sub-system, the third port being connectable to the first antenna, the fourth port being connectable to the second antenna wherein the first antenna and second antenna each operating with a radio frequency (RF) filter, the two RF filters having non-overlapping pass bands for improving isolation between the transmitter sub-system and receiver sub-system.
