Abstract
A translating bi-directional packet repeater includes a first antenna and a second antenna for receiving a wireless signal, amplifying it, and retransmitting it on a different channel. The channel associated with each of the antennas is separated in frequency sufficiently to ensure good isolation between the wireless signals that are received and then retransmitted. The wireless signal is down converted to an intermediate frequency (IF) that is passed through a band pass filter, and the filtered signal is then up converted and retransmitted on the different channel. A controller responds to a wireless signal on one of the antennas in selecting a path through the bi-directional amplifier and the antennas used to receive and retransmit the signal. The isolation between the received wireless signal and the retransmitted wireless signal is sufficient to avoid interference, and the retransmission takes place almost instantaneously to minimize the delay incurred.
