US 5,848,062 A · Wireless communication equipment for remote station

Abstract

Wireless TDMA communication equipment for a remote station which does not require inner temperature control circuit in order to control the temperature, comprising battery saving control circuit wherein the signal indicating whether or not a signal from a two-wire/four-wire converter exists and an output from a temperature sensor is received, when the signal to be transmitted to the wireless communication equipment does not exist, a time for intermittently operating the power source supplied to the wireless communication equipment is changed according to the output from the temperature sensor, and a temperature control portion having data rate control circuit wherein when the signal to be transmitted exists, the battery saving circuit is stopped, so that a coding rate of the wireless communication equipment and a transmission burst time are changed according to the temperature detecting circuit.
