How Do I Deploy a Wireless LAN?
Wireless Network Speeds
Having to accommodate multiple standards due to older or incompatible routers and NICs is just one of several factors that can slow down a wireless LAN. Another is the distance you anticipate your wireless computers and resources will be from your access points and routers. Radio frequency (RF) interference is another factor that can significantly impact your wireless network's speed.
Wireless networks that operate in the 2.4 GHz frequency band (802.11b and 802.11g) will be working in the same frequency range as cordless phones, Bluetooth devices, wireless video cameras, microwave ovens and baby monitors, all of which can cause significant interference with your wireless network and degraded performance as a result. Wireless LANs that operate in the 5 GHz frequency band (802.11a and 802.11n, which utilizes both the 5 GHz and 2.4 GHz frequencies) may find RF interference in the form of newer cordless phones and other devices.
