P2612HNU Fx Support Notes

What is 802.11n?

802.11n supports frequency in both 2.4GHz and 5 GHz and its data rate from 54
Mbit/s up to 600 Mbit/s in theory; in the 802.11n Channel Doubling technology witch
can double the bandwidth from 20 MHz to 40 MHz and effectively doubles data rates
and throughput. It adds MIMO feature, which using multiple transmission and
reception antennas to allow higher raw rate, and resolve more information using a
single antenna possibility. It also uses the "Alamouti coding" coding schemes to
increase transmission range.

Is it possible to use products from a variety of vendors?

Yes. As long as the products comply to the same IEEE 802.11 standard. The Wi-Fi logo
is used to define 802.11b compatible products. Wi-Fi5 is a compatibility standard for
802.11a products running in the 5GHz band.

What is Wi-Fi?

The Wi-Fi logo signifies that a product is interoperable with wireless networking
equipment from other vendors. A Wi-Fi logo product has been tested and certified
by the Wireless Ethernet Compatibility Alliance (WECA). The Socket Wireless LAN
Card is 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
