Design and Investigation of Photonic Remote Antenna Units for Bidirectional Transmission in the Last Mile Wireless over Fiber System

摘要

In the article three different photonic Remote Antenna Units (RAU) in the last mile Wireless over Fiber links are presented. For construction of RAU commercially available optoelectronic devices were used. The solutions differ from each other by the method of ensuring isolation between transmitting and receiving modes of operation. All RAUs were designed, realized and measured in various scenarios. The results prove that all propositions can be successfully applied to uplink and downlink IEEE 802.11b/g wireless LAN systems, employing Wireless over Fiber technique.
