Symbols & Numeric
802.11
A group of wireless specifications developed by the IEEE. It details a wireless interface
between devices to transport packet traffic.
802.11a
Operates in the 5 GHz frequency range with a maximum 54 Mbit/sec signaling rate.
802.11b
Operates in the most commonly used 2.4 GHz Industrial, Scientific, and Measurement
(ISM) band. Provides signaling rates of up to 11 Mbit/sec using CCK modulation.
802.11g
Similar to 802.11b but supports signaling rates of up to 54 Mbit/sec using OFDM
modulation. Operates in the heavily used 2.4 GHz ISM band.
802.11i
Sometimes called Wi-Fi Protected Access 2 (WPA 2). WPA 2 exclusively uses the 128-
bit and above Advanced Encryption Standard (AES), along with 802.1x authentication
and key management features.
802.11n
Uses higher modulation rates and packet aggregation 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 (clients) to a wired
network. Some access points (APs) can also bridge to other APs.
Ad hoc Mode
Wireless network framework in which devices can communicate directly with one
another without using an accesspoint or a connection to a regular network. RLX2-IHx
series radio products do not support Ad hoc mode.
AES
Advanced Encryption Standard. New standard for encryption adopted by the U.S.
government for secure communications.
Amplifier
A device connected to an antenna that increases the signal strength and amplifies weak
incoming signals.
Antenna
A device connected to a wireless transceiver that concentrates transmitted and received
radio waves to increase signal strength and thus the effective range of a wireless
network.
