Re: How Much Speed Loss Due to Wireless Overhead?
My DSL package isn't capped, and with my lines and distance from the CO I can get about 4 Mbps down straight from the modem to the laptop. Via the wireless network without WEP enabled I get around 3.7 Mbps down, with WEP enabled I get between 2.7 and 3.2 Mbps. My main question is this: Compared to a wired network, about what percent of overhead loss will the average 802.11b show? |

| Well what you can do is download a program like qcheck and run it on 2 computers on your network. Do a test through your wired switch first, and then over the WLAN. On my network I have found net throughput on a 100Mbps switch to be around 90Mbps or so (10%), and on an 802.11b WLAN net throughput is around 4Mbps unencrypted, and on a .11g WLAN, 18 or 19Mbps unencrypted. So if you do the math for the 11Mbps you see about 36% and for 802.11g 33%. These are just what I have found in my network and seem to be about what I have read for others. WEP does provide overhead, again, just do some testing and see for yourself. |
