Abstract
A wireless modem comprises an antenna, modem circuitry, a first galvanic isolation device, and a second galvanic isolation device. The antenna is configured to transmit and receive wireless signals and to communicate electronic transmit and receive signals. The modem circuitry is configured to convert transmit data from a data processing system to the electronic transmit signal for the antenna and to convert the electronic receive signal from the antenna to receive data for the data processing system. The first galvanic isolation device is configured to electrically isolate the electronic transmit and receive signals between the antenna and the modem circuitry. The second galvanic isolation device is configured to receive electrical power from the data processing system and supply isolated electrical power to the modem circuitry and to electrically isolate the transmit and receive data between the modem circuitry and the data processing system.
