PDF of this tutorialAMPS
advanced mobile phone service; another acronym for analog cellular radio
BTS
base transceiver station; used to transmit radio frequency over the air interface
CDMA
code division multiple access; a form of digital cellular phone service that is a spread spectrum technology that assigns a code to all speech bits, sends scrambled transmission of the encoded speech
DAMPS
digital advanced mobile phone service; a term for digital cellular radio in North America.
DCS
digital cellular system
E–TDMA
extended TDMA; developed to provide fifteen times the capacity over analog systems by compressing quiet time during conversations
ESN
electronic serial number; an identity signal that is sent from the mobile to the MSC during a brief registration transmission
FCC
Federal Communications Commission; the government agency responsible for regulating telecommunications in the United Sates.
FCCH
frequency control channel
FDMA
frequency division multiple access; used to separate multiple transmissions over a finite frequency allocation; refers to the method of allocating a discrete amount of frequency bandwidth to each user
FM
frequency modulation; a modulation technique in which the carrier frequency is shifted by an amount proportional to the value of the modulating signal
FRA
fixed radio access
GSM
Global System for Mobile Communications; standard digital cellular phone service in Europe and Japan; to ensure interpretability between countries, standards address much of the network wireless infra
Hz
hertz; a measurement of electromagnetic energy, equivalent to one wave or cycle per second
kHz
kilohertz; thousands of hertz

megahertz; millions of hertz
MS or MSU
mobile station unit; handset carried by the subscriber
MSC
mobile services switching center; a switch that provides services and coordination between mobile users in a network and external networks
MTSO
mobile telephone switching office; the central office for the mobile switch, which houses the field monitoring and relay stations for switching calls from cell sites to wireline central offices (PSTN)
MTX
mobile telephone exchange
NADC
North American digital cellular (also called United States digital cellular, or USDC); a time division multiple access (TDMA) system that provides three to six times the capacity of AMPS
NAMPS
narrowband advanced mobile phone service; NAMPS was introduced as an interim solution to capacity problems; NAMPS provides three times the AMPS capacity to extend the usefulness of analog systems
PCS
personal communications service; a lower-powered, higher-frequency competitive technology that incorporates wireline and wireless networks and provides personalized features
PSTN
public switched telephone network; a PSTN is made of local networks, the exchange area networks, and the long-haul network that interconnect telephones and other communication devices on a worldwide b
RF
radio frequency; electromagnetic waves operating between 10 kHz and 3 MHz propagated without guide (wire or cable) in free space
SIM
subscriber identity module; a smartcard which is inserted into a mobile phone to get it going
SNSE
supernode size enhanced
TDMA
time division multiple access; used to separate multiple conversation transmissions over a finite frequency allocation of through-the-air bandwidth; used to allocate a discrete amount of frequency ban
