On 10Gbps Terahertz wireless communication systems

In order to increase the short range wireless communication to 10 Gbps, a Terahertz wireless communication system combing electro-optical technology with THz band (125 GHz) for carrier was build, which adopted 125 GHz optical THz generator, UTC-PD module, HEMT module and cassegrain antenna (CA) or Gaussian optic lens antenna (GOA) to improve system performance. It gives the researches about theoretical analysis and simulation results on output power, noisiness, relation between communication quality and antenna, data transmission feature, maximum transmission distance and so on. Experimental result shows that: the carrier to noise ratio of emission signal meets error-free transmission demand, 125 GHz waveband wireless communication supports OC-192 network interface and 10 GbE network interface. So, it´s feasible to realize 10 Gbps wireless communication using electro-optical technology.
