On the last day spent at the Long Gully Tower I installed a Point-to-point to a home of BeWiFi enthusiast members. The link is approximately 4.8km's and the signal roughly -68dBm in a 20MHz channel. I have to go back to each point to line it up tighter and will expect a signal of about -56dBm. Currently in the 20MHz MIMO channel mode TCP/IP throughput is a steady 75Mbps however can expect 150Mbps+ in a 40MHz channel after the re-alignment.
