interference, such as airplanes and hospitals.
There is no
means to shut off the Bluetooth and WLAN radios installed in the system.
For PAN environments, Bluetooth provides freedom from wired connections. By using this radio-based link,
computers, mobile phones, PDA and other portable handheld devices are able to transmit data to each other or
connect to Internet without a single cable.

The Bluetooth wireless technology and Wireless LAN (802.11b
/g) are complementary technologies. The Bluetooth
wireless technology is designed to replace cables between cell phones, laptops, and other computing and
communication devices within a 10-meter range. Wireless LAN is wireless Ethernet; it provides an extension or
replacement of wired networks for dozens of computing devices.

Issues do arise with the coexistence of both Bluetooth and Wireless LAN. Any time devices are operated in the same
frequency band, there is the potential for interference which results in a lower bandwidth
