A 143 GHz InP-based radio link characterized in long-term outdoor measurement

Paper in proceedings, 2019

This paper reports on a 143 GHz radio link, evaluated in long-term outdoor measurements over a 200 m hop-length. The link has been characterized with a variable attenuator in a back-to-back configuration. For the outdoor tests the received power level and signal quality have been monitored for two months under various weather conditions. The radio link shows a highest throughput of 5.3 Gbps using 64 QAM and 1 GHz carrier bandwidth. The corresponding mean squared error of the demodulated signal is-25 dB, and the receiver sensitivity level is-42 dBm with 3 dB penalty compared to the theoretically calculated value for this setup. The long-term outdoor test is run at QPSK and 125 MHz carrier bandwidth.
