Re: How Much Speed Loss Due to Wireless Overhead?
All these radio technologies are inherently half-duplex. So it's better if you compare them to a 10 or 100 connection with both ends set to half, than to your typical modern setup with everything at full duplex. There is significant overhead anytime you have to stop receiving to transmit back acknowledgements and send next packet. Also, just the nature of the radio designs involves much more overhead. 11 megs is never 11 megs, maybe half that. I should toss in that the lower-end wireless AP's will not have enough processing power to do WEP-128 without impact. Later units with an ARM9 chip for example the WEP degradation should be less noticable.
Like someone else said, your best numbers are gotten by doing experiments on local LAN first to isolate the numbers. |
