Patent ID: 7609665

Claim:
A wireless repeater between first and second apparatuses communicating in a first bandwidth, including: a communication module for communicating with the first apparatus through a first communication line of the first bandwidth; a plurality of wireless communication units, each for communicating with the second apparatus through each of a bundle of second communication lines, where each second communication line is a wireless communication line of a second bandwidth and the bundle of second communication lines has the first bandwidth; and a band control unit for automatically recognizing one or more of the wireless communication units that are added during operation, or the wireless communication unit that is lost during operation, as a result of the recognizing, dynamically determining a number N of usable wireless communication units, and dynamically increasing or decreasing the capacity of the first bandwidth of the first communication line according to increase or decrease in the determined number N of the usable wireless communication units, through dividing data in the first bandwidth into the determined number N of the second bandwidths, and through N-fold-multiplexing data in the second bandwidths into the first bandwidth.
