Thanks for jumping in, Peter, and for adding those data points, although I'll probably need to refer to the actual specifications in order to make full sense of them. In any case, I wasn't referring to packet size or compression algorithms, but rather the lower likelihood of encountering congestion, and the reduced likelihood of talkers stepping on one another. Are these misguided notions, in your opinion? Come back ... ------

Peter, I now see what you mean, after posting my earlier note, which the edit timer didn't permit me to change ;) ------

Hi Peter - Research revealed one aspect of .11n where an exception was made for mobile devices because of the additional power drain conferred by MIMO. "But the Wi-Fi Alliance (WFA) has waived the MIMO requirements for handsets, allowing 802.11n certification for single-radio devices. So none of these increases in power dissipation needs to apply to handsets. Single-channel 802.11n still requires more processing than single channel 802.11g, because of advanced features like STBC and LDPC, but STBC and LDPC are amenable to hardware implementation (which reduces their power demand), and these and other advanced features of 802.11n improve “rate at range,” meaning that the transmitter is active for shorter times, and can transmit at lower power" wirevolution.com Jim
