Short-Range Full-Duplex Real-Time Wireless Terahertz Link for IEEE802.15.3d Applications

This paper presents experimental results of a shortrange real-time full-duplex wireless link operating at frequencies between 285 and 315GHz. Using modems with integrated E-band frontends in conjunction with H-band transmitters and receivers a super-heterodyne link architecture is implemented. Over a line-of-sight distance of 0.5 meter a maximum troughput of 11.09Gbps is achieved using complex modulation formats as high as 64-QAM. The wide LO input frequency tuning range of the H-band transmitter and receiver modules from 70 to 76.5GHz as well as the availability of multiple modem channels with up to 2GHz bandwidth enable the compatibility of the link with the IEEE802.15.3d frequency standard and its channels 15 through 28. The testbed is operated with two standalone PCs generating, sending, receiving and processing real traffic data over a 10Gbps Ethernet connection to the modems.
