Some Terminology

MobileQuests GlossaryThey really have it all

Ziff-Davis Webopedia Communication Technology

CDMA Short for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use time-division multiplexing (TDM), CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence.

• CDMA2000 \ CDMAONE The IS-95 CDMA standard developed by Qualcomm Inc, it is a third generation wireless technology
• W-CDMA Wideband Code Division Multiple Access The third generation standard offered to the International Telecommunication Union by GSM proponents

COLT Cell site on light truck(OBSCURE) A mobile site on a vehicle placed at a location to fill in or increase coverage

COWS Cell site on wheels(OBSCURE) man I'd like to get my hands on one of these.

DISCO II FCC proceeding on domestic-international satellite service consolidation. (Sorry to confuse you with useless facts, but I had to include this one.)

EDACS Enhanced Digital Access Communications System(OBSCURE) A private radio or specialized mobile radio network designed by Ericsson Inc.

ESN Electronic Serial NumberThink of this as the fones unique serial number coded at the manufacturer. Each time a call is placed, the ESN is automatically transmitted to the switch so the carrier can check the call's validity. The ESN differs from the Mobile Identification Number, which is the carrier's identifier for a phone in the network.

FLEX A Motorola Inc.-licensed protocol that gives carriers more capacity on their networks and faster transmission times. Also refers to the FLEX family of protocols: FLEX, InFLEXion and ReFLEX. (Flex-paging?)

• InFLEXion The narrowband PCS technology developed by Motorola Inc. that allows for voice paging. It has been adopted by carriers such as Paging Network Inc. and Conxus Communications Inc.
• ReFLEX 25 Narrowband PCS technology that allows for two-way text messaging.
• ReFLEX 50The proprietary two-way system implemented by SkyTel Communications Inc.

FHMA Frequency Hopping Multiple Access(OBSCURE) A spread-spectrum technology used in Geotek Communications Inc.'s specialized mobile radio network.

GSM Short for Global System for Mobile Communications,popular in europe one of the leading digital cellular systems. GSM uses narrowband TDMA, which allows eight simultaneous calls on the same radio frequency.

• GSM-Plus An enhanced version of GSM that will be developed to meet third generation international requirements.
• GSM-R Global System for Mobile Communications for Railway uses standard base station and switching infrastructure to provide fast data transmission for railways.

HDML Handheld Device Markup Language Text only markup language, similar to HTML, (I.e. SPRINTs "Wireless Web") One version of HDML is Unwired Planet Inc.'s UP.Link.

MIN Mobile Identification Number This is a unique ID number for the network (assigned by the access carrier)

MTSO Mobile Telephone Switching Office

NAMPS Narrowband Advanced Mobile Phone System Hybrid AMPS systems and adding functionality. Digital over analog.

NCIC National Crime Information Center What the police acess in their patrol cars over CDPD.

OTASP Over The Air Service Provisioning The ability to upgrade a fones software functionality over the airwaves, possible security issue.

PCS Personal Communications Service Second generation of cellular. The U.S. Federal Communications Commission (FCC) term used to describe a set of digital cellular technologies being deployed in the U.S. PCS includes CDMA (also called IS-95), GSM, and North American TDMA (also called IS-136). These systems operate soley digital at the 1900 MHZ range.

POCSAG Post Office Code Standards Advisory Group This acronymn references a paging system "beepers." U.K. in origin.

RF Fingerprinting A process that identifies a cellular phone by the unique "fingerprint" that characterizes its signal transmission. RF fingerprinting is one process used to prevent cloning fraud, How often is this employed? What if you use the same model fone, what about a digital signal?

SIM \ SMART CARD Subscriber Identity Module Synonymous with smart card, these systems use a PIN as another security measure.

• Smart card A plastic card containing important data about a person's identity to allow access to a network or premises. Also, a card containing subscriber information, often inserted into GSM phones for roaming to different countries.

TDMA Short for Time Division Multiple Access, a technology for delivering digital wireless service using time-division multiplexing (TDM). TDMA works by dividing a radio frequency into time slots and then allocating slots to multiple calls. In this way, a single frequency can support multiple, simultaneous data channels

• D-AMPS (digital AMPS) (AMPS= Advandced Mobile Phone Service) Used by Ericsson Inc. to describe IS-136 TDMA.
• IS-54 First generation TDMA
• IS-136 Current version of TDMA
