Blocking Object Effect in Propagation Channel of Millimeter Wave Wireless Communication

We demonstrate experimentally short range, line-of sight (LOS) millimeter wave wireless communication in the 300 GHz carrier frequency based on optical frequency comb generator (OFCG) as its signal source. The transmitter was based on photonics system whereas the receiver was based on electronics. The data transmission test was generated using bit error rate tester (BERT) scope with a length of 2 ⁷ -1 and a data rate of 10 Gbit / s. Five different blocking objects have been employed to investigate the system performance in the propagation channel. The evaluation performance of the system is based on bit error rate (BER) at various positions in propagation channel for each object. The link distance can reach up to 8 cm with minimum BER is 0.864 E-03.
