802.11b's low cost of entry is what makes it so attractive. However, inexpensive equipment also makes it easier for attackers to mount an attack. "Rogue" access points and unauthorized, poorly secured networks compound the odds of a security breach. The 802.11b standard shares unlicensed frequencies with other devices, including Bluetooth wireless Personal Area Networks (PANs), cordless phones, and baby monitors.

An approach to WLAN security using Pseudo Random codes promises to address such shortcomings.
