Cellular/Wireless LAN Repeater System by Wireless Optical Link with Optical Power Supply

Wireless markets such as cellular systems and wireless LAN, becomes huge and is still expanding. Since operational frequency and transmission bit rate are increasing, much more base stations or access points are necessary to overcome capacity and link budget problems. Most of the places suitable for the base station were already occupied by the existing systems. In the future, sometimes, new base station must be installed at the places where power supply or transmission cable is not available. The proposed repeater system is applicable for such case. The RF signals are fed to the repeater through the air by optical beams. And electrical power is fed by the optical beam, too.
