Chapter 22 – CDMA
Second Generation. This is an all digital cellular systems developed to replace the first
analog cellular systems. (GSM and CDMA).
Third Generation. This is the next generation digital cellular systems designed to have
high-speed data access and higher voice capacity (CDMA & CDMA2000).
Advanced Forward Link Trilateration. A type of handset-based position location
technology. GPS satellites are not used to determine location. To determine location
using AFLT, the phone takes measurements of signals from nearby cellular base stations
(towers) and reports the time/distance readings back to the network, which are then used
to triangulate an approximate location of the handset. In general, at least three
surrounding base stations are required to get an optimal position fix.
CDMA (Code Division Multiple Access). CDMA is a spread spectrum, digital cellular
modulation scheme for cellular communications systems. It has approximately 3 times
the voice capacity of GSM networks. See IS-95, IS-95B, IS-2000.
cdmaOne is a brand name, trademarked and reserved for the exclusive use of the
CDMA Development Group (see their Web site at cdg.org). cdmaOne describes a
complete cellular system that incorporates the IS-95 CDMA air interface, the ANSI-41
network standard for switch interconnection and many other standards that make up a
complete cellular system.
cdma2000 is a third generation (3G) cellular system. It contains a significant increase in
voice capacity and high-speed data rates. It is backward compatible with IS-95B and IS-
95A.
"1xRTT" stands for 1 times Radio Transmission Technology and is used to identify the
version of CDMA2000 radio technology that operates in a pair of 1.25-MHz radio
channels (one times 1.25 MHz, as opposed to three times 1.25 MHz in 3xRTT). Although
theoretically capable of higher data rates, most carrier implementations have limited the
peak data rate to 144 kbit/s. While 1xRTT officially qualifies as 3G technology, 1xRTT is
considered by some to be a 2.5G.
Data Communications Equipment. This is the modem in the traditional serial
communication paradigm of a computer connected via two modems to another computer.
Data Terminal Equipment. This is the computer in the traditional serial communication
paradigm of a computer connected via two modems to another computer.
Dual Tone Multi-Frequency: A pre-defined set of tones sent over the air when keys are
pressed on the keypad.
"ESN" stands for Electronic Serial Number. It is a 32-bit binary number that identifies
each cellular phone.
Handset (Path). This is the audio path (microphone & speaker) that connects to a
traditional hand held telephone receiver, usually dual balanced electrical lines.
Headset (Path). This is the audio path (microphone & speaker) that connects to an
earpiece with a microphone, usually single electrical lines.
International Mobile Station IS. This is an international 15 digital phone number that
uniquely identifies a mobile. IMSI=MCC + MNC + MIN.
IOTA stands for Internet Over The Air.
