802.11
A group of wireless specifications developed by the IEEE. It details a wireless
interface between devices to manage packet traffic.
802.11a
Operates in the 5 GHz frequency range with a maximum 54 Mbit/sec signaling
rate.
802.11b
Operates in the 2.4 GHz Industrial, Scientific, and Measurement (ISM) band.
Provides signaling rates of up to 11 Mbit/sec and is the most commonly used
frequency.
802.11g
Similar to 802.11b but supports signaling rates of up to 54 Mbit/sec. Operates in
the heavily used 2.4 GHz ISM band but uses a different radio technology to boost
throughput.
802.11i
Sometimes Wi-Fi Protected Access 2 (WPA 2). WPA 2 supports the 128-bit and
above advanced encryption Standard, along with 802.1x authentication and key
management features.
802.11n
Designed to raise effective WLAN throughput to more than 100 Mbit/sec.
A
Access Point
A generic term for an 802.11 radio that "attaches" other 802.11 radios (clients) to
a wired network. Some APs can also bridge to one another.
Ad hoc Mode
Wireless network framework in which devices can communicate directly with one
another without using an AP or a connection to a regular network. RLX2 radio
products do not support Ad hoc mode.
AES
