    In laser interferometer gravitational wave detectors, local control relative to vibration isolated parts of a suspension chain may introduce noise through wires. In this paper we present a feasibility study of a wireless signal transmission method for control systems. A prototype system provides a wireless two-way signal transmission over short distances at more than 800 kbits s(-1). Wireless electric power for the system may be provided using a diode laser and solar cells with up to 33% conversion efficiency.
