Multi-hop booster
First Claim
1. A repeater that mediates traffic between a network transceiver and a user transceiver in a cellular wireless communication network, the repeater comprising:
- a network unit having at least one wireless receiver and at least one wireless transmitter, the network unit being configured to communicate with the network transceiver;
a user unit having at least one wireless receiver and at least one wireless transmitter, the user unit being configured to communicate with the user transceiver;
a two-way communication path between the network unit and the user unit to communicate signals between the network transceiver and the user transceiver in autonomous hops comprising between the network transceiver and the network unit, between the user transceiver and the user unit, and between the network unit and the user unit;
the hop between the network unit and the user unit being wireless for communicating a signal, and including each of wireless receivers of the user unit and the network unit using at least one channel equalizer to reduce propagation channel time dispersion and fading on the signal; and
at least one of the network unit and the user unit being further configured to repeatedly transmit a training sequence to other unit of the network unit and the user unit to train the at least one channel equalizer of the other unit, the training sequence being transmitted in a guard time of a time division multiplexing communication on the hop between the user unit and the network unit, the guard time being between timeslots of the time division multiplexing communication.

Abstract
A two-way wireless repeater and booster system and method with watermarking of uplink signals are disclosed. The repeater includes a network unit having at least one wireless receiver and at least one wireless transmitter, the network unit being configured to communicate with the network transceiver. The transceiver further includes a user unit having at least one wireless receiver and at least one wireless transmitter, the user unit being configured to communicate with the user transceiver, and a two-way communication path between the network unit and the user unit to communicate signals between the network transceiver and the user transceiver in autonomous hops comprising between the network transceiver and the network unit, between the user transceiver and the user unit, and between the network unit and the user unit. The network unit and/or user unit is further configured to repeatedly transmit a training sequence to the other unit to train the at least one channel equalizer of the other unit.
