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.
