Wired netowrks have very low overhead, typicly single digit percentages. > Wireless LAN speeds: 802.11b can reach 11Mbps max. 802.11g can reach > 54Mbps max. 802.11n can reach 540Mbps max. > > There is more noise on wireless connections so the "max" on wireless is > not as "max" as the "max" on the wired connections =P 802.11b feels > a lot like 5Mbps to me most of the time. WiFi has overhead of around 100%, and rates quoted are always the gross data rate including all overhead. 802.11n isn't a standard yet. Standards based 802.11g kit gets around 20 to 25 Mbps Also note that WiFi is half duplex and shared media; only one station can successfully transmit at once. Even worse, in managed mode (at least, with stardards complaint gear), client stations must communicate amongst each other through the Access Point; resulting in major speed decreases. There are a lot of things WiFi is good at, but being fast is not one of them. -- Ryan Castellucci - http://ryanc.org/ GPG Key: http://ryanc.org/files/publickey.asc _______________________________________________ vox-tech mailing list [email protected] http://lists.lugod.org/mailman/listinfo/vox-tech
