802.11. A group of wireless specifications developed by the Institute of Electrical and Electronics Engineers
(IEEE). It specifies an over-the-air interface between a wireless client and a base station or between two
wireless clients.
802.11a. Operates in the 5 GHz frequency range (5.125 to 5.85 GHz) with a maximum 54Mbit/sec. signaling
rate. The 5 GHz frequency band is not as crowded as the 2.4 GHz frequency because it offers significantly
more radio channels than the 802.11b and is used by fewer applications. It has a shorter range than 802.11g
and is not compatible with 802.11b.
802.11b. Operates in the 2.4 GHz Industrial, Scientific and Measurement (ISM) band (2.4 to 2.4835 GHz) and
provides signaling rates of up to 11Mbit/sec. This is a very commonly used frequency. Microwave ovens,
cordless phones, medical and scientific equipment, as well as Bluetooth devices, all work within the 2.4 GHz
ISM band.
802.11g. Similar to 802.11b, but this standard supports signaling rates of up to 54Mbit/sec. It also operates in
the heavily used 2.4 GHz ISM band but uses a different radio technology to boost overall throughput.
Compatible with the 802.11b.
A
Access Point. Provides a bridge between Ethernet wired LANs and the wireless network. Access points are
the connectivity point between Ethernet wired networks and devices (laptops, hand-held computers,
point-of-sale terminals) equipped with a wireless LAN adapter card.
Ad Hoc Mode. A wireless network framework in which devices communicate directly with one another without
using an access point.
API. An interface by means of which one software component communicates with or controls another. Usually
used to refer to services provided by one software component to another, usually via software interrupts or
function calls
Application Programming Interface. See API.
ANSI Terminal. A display terminal that follows commands in the ANSI standard terminal language. For
example, it uses escape sequences to control the cursor, clear the screen and set colors. Communications
