Location A Radio A Ant A 2 Km Location B Radio B Ant B A point-to-point wireless bridge needs to be set up between two sites A and B which are 2km apart. The received power Prx at the radio needs to be -64 dBm. The antenna gain at both locations needs to be the same. The transmit power (Ptx) is 11 dBm. Ignore the tree for now. Answer the following design questions. What is the value of antenna gain in dBi at each location? The radios are operating with N=108 data subcarriers, T=4us and S-1 spatial stream. What is the PHY rate of the radio in Mbps? HINT: See tables in Information Sheet. In the summer, tree leaves in the path add an additional loss of 6 dB. What is the new PHY rate in Mbps? A/
