Hi Frank: When I looked at the specs of WMUX's gigabit Ethernet wireless Tsunami radios, it looked like they needed 100MHz (as indicated by transmission). So, at a 720Mb/sec, this suggest about 7bits/Hz/sec. Since some excess bandwidth is needed, we are probably talking about at least 256 QAM, and probably 512-QAM. A few months ago, Rob Preuss posted a detailed analysis of bit/Hz/sec performance of current and forthcoming STXN's Altium radios. Best regards, Bernard Levy
