Abstract: A first repeater comprising an input node for receiving downstream signals and re-transmitting the data sent over these signals on a non-license frequency. The first repeater further comprising another input node for receiving upstream signals sent over another non-license frequency, and re-transmitting the data over the upstream channel. In another embodiment of the system a second repeater is wirelessly coupled with the first repeater such that the second repeater receives the downstream data over a first non-license frequency and re-transmits the data over the first non-license frequency. The second repeater is further capable of receiving the upstream data over a second non-license frequency and re-transmitting the data over the second non-license frequency.

Abstract: An apparatus and method is described for providing high-speed wireless upstream data transmission using cable-compatible modems. The data is modulated by a cable-compatible modem and upconverted to a wireless channel by a frequency translator. The average field strength of the transmitted signal is constrained by controlling the duty cycle, and may be more accurately constrained by additionally controlling the gain of the frequency translator through feedback. Limiting the average field strength permits transmission over unlicenced wireless channels.
