802.11x COMMENTS
Distance is the primary problem with wireless. The farther away you are, the poorer the signal. Although 802.11a wireless access points are four times as fast as 802.11b hubs, they can send signals only about half the distance.
The Wired Equivalent Privacy algorithm (WEP), the 128-bit security protocol for 802.11b, offers minimal security for an office network because any user with an 802.11b connection can achieve certain levels of network connectivity despite WEP. The WEP algorithm is used to protect wireless communication from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless network; this function is not an explicit goal in the 802.11 standard, but it is frequently considered to be a feature of WEP.
