Experimental research of intra-corporate network radio-mobile segment based on Radio-over-Fiber technique

This work proposes solution for intra-corporate network radio-mobile segment realization based on Radio-over Fiber (RoF) technique. Results of developed prototype experimental researches are represented. Here radio-mobile network 300 MHz band was used. Yagi-Uda antennas with power gain 11 dB were used for base station (BS) and remote antenna units (RAU). Experimental tests were performed over typical urban area. Central station (CS) as well as BS were situated in industrial building, whide RAU was placed in office building over 400 m distance from BS. Antenna suspension heights were set therefore line-of-sight was block by adjacent buildings and constructions. There was various operating manufactory and industrial equipment near BS that causes strong distortions over radiofrequency band. Electric transport aerial contact wire lines installed near RAU were additional distortion source. This work presents results of experimental measurements that contained channel quality estimation by two telephone sets been connected to CS and RAU, BER measurements during modem connection performed by conventional utility Hyper Terminal, time delay and packet loss measurements under remote connection according to method RFC-2544.
