Tower top antenna structure with fiber optic communications link

摘要

An intermediate frequency (IF) fiber optic communications link communicates receive and transmit signals between a distributed active antenna and base station electronics in an antenna installation. In addition, a tower top antenna structure incorporates both an RF transceiver and an optical transceiver in connection with a distributed active antenna to permit conversion between the RF signals utilized by a distributed active antenna with optical IF signals communicated over the fiber optic communications link. Complementary electronics at the base station then convert between the optical IF signals and digital IF signals for interface with base station electronics.
