Computer Networking: Bluetooth Wireless
BlueTooth Wireless Networking
Bluetooth is an alternative wireless network technology
that followed a different development path than the 802.11
family of standards. Bluetooth offers more flexibility
than 802.11b but on a smaller range and speed. Its bandwidth
is only 500Kbps, and its range is only 10 meters (30 feet).
Devices with a Bluetooth radio and an antenna can speak
to each other with little or no preparation. For example,
conference attendees can readily transfer files across a
table using their Bluetooth-enabled notebooks. You can also
send a file to a Bluetooth-enabled printer without downloading
drivers. Bluetooth may soon be a standard interface on many
cell phones, handheld computers, and even home appliances.
However, it is going to take sometime before the hardware
and software issues are resolved completely. Bluetooth operates
at 2.4GHz, and is subject to the same interference problems
as 802.11b and 802.11g. Compare the WLAN technologies.
