Transmission over hundreds of meters and line rates exceeding 100 Gbit/s were demonstrated [5]-[10]. Typical atmospheric losses are 0.2 dB/100 m at 0.2 THz, 0.5 dB/100 m at 0.3 THz, 1.5 dB/100 m at 0.4 THz, and 5 dB/100 m at 0.9 THz. For transmission over a 100 m-distance, however, the unity-gain free-space propagation loss a L=100m dB = 10lg(4pL/l) 2 = 120dB (l = 1mm, f = 0.3THz) dominates. To combat this propagation loss, multiple directional antennas with a high gain per sector can be employed at the base station to boost the reach and the data throughput on transmission and reception.en621Wireless terahertz communicationsconference paper
