   So from what I have been able to put together so far the advertised throughput is directly related to the type of network you are talking about. Wired vs Wireless. 100BaseT vs 802.11N

   The 100BaseT spec advertises 100Mbps but that is a half duplex advertisement. If you run Full Duplex then it becomes 100Mbps in both directions at the same time for a total throughput of 200Mb in one second correct?

   What I am being told is that 802.11N does it completely different. The manufacturers advertising of 150Mbps is a Full Duplex advertisment. 75Mbps in both directions at the same time (Full Duplex). A total of 150Mb in one second. FYI it is low because it is in the 5Ghz band over a really long distance.

   You can carry this 802.11N "advertising" to what most wireless manufactures advertise as 300Mbps. It is really 150Mbps in each direction at the same time for a total throughput of 300Mb in one second.

   So the long and short of it is 100BaseT is advertised in Half Duplex numbers and 802.11N is advertised in Full Duplex numbers. Can anyone confirm of deny my understanding?
