Wi-Fi certified, and that means that it will work (interoperate) with any brand of
Access Point that is also Wi-Fi certified.
What types of devices use the 2.4GHz Band?
Various spread spectrum radio communication applications use the 2.4 GHz band.
This includes WLAN systems (not necessarily of the type IEEE 802.11b), cordless
phones, wireless medical telemetry equipment and Bluetooth™ short-range wireless
applications, which include connecting printers to computers and connecting
modems or hands-free kits to mobile phones.
Does the 802.11 interfere with Bluetooth devices?
Any time devices are operated in the same frequency band, there is the potential for
interference.
Both the 802.11b and Bluetooth devices occupy the same2.4-to-2.483-GHz
unlicensed frequency range-the same band. But a Bluetooth device would not
interfere with other 802.11 devices much more than another 802.11 device would
interfere. While more collisions are possible with the introduction of a Bluetooth
device, they are also possible with the introduction of another 802.11 device, or a
new 2.4 GHz cordless phone for that matter. But, Bluetooth devices are usually
low-power, so the effects that a Bluetooth device may have on an 802.11 network, if
any, aren't far-reaching.
Can radio signals pass through walls?
Transmitting through a wall is possible depending upon the material used in its
construction. In general, metals and substances with high water content do not allow
radio waves to pass through. Metals reflect radio waves and concrete attenuates
radio waves. The amount of attenuation suffered in passing through concrete will be
a function of its thickness and amount of metal re-enforcement used.
