communications technology, introducing
digital voice encoding. Low speed data
services are supported.
CDMA – Code Division Multiple Access
A general term describing mobile air interface
technologies based on “spread spectrum”
digital radio access methods, offering benefits
including increased capacity, quality and
security. CDMA is fundamental to 3G mobile
systems.
3G – Third Generation

wireless clients. Available channels depend
on region specific regulations.
ALG – Application Layer Gateway
An ALG provides a translation and
transportation service for an Internet
application.
CHAP – Challenge-Hanshake
Authentication Protocol
CHAP is an authentication scheme used by
PPP servers to validate the identity of remote
clients. CHAP periodically verifies the identity
of the client by using a three-way handshake.
This happens at the time of establishing the
initial link, and may happen again any time
afterward. The verification is based on a
shared secret (such as the client user’s
password). See also PAP.
AES – Advanced Encryption Standard
An encryption method used by WPA2. AES
offers a high level of security and is approved
for sensitive corporate and government data
transmission.
AP – Access Point
An Internet device that seamlessly connects
wired and wireless networks. Access points
attached to a wired network support the
creation of multiple radio cells that enable
roaming throughout a facility.
