EDGE

Enhanced Data rates for GSM Evolution; effectively the final stage in the evolution of the GSM standard, EDGE uses a new modulation schema to enable theoretical data speeds of up to 384kbit/s within the existing GSM spectrum. An alternative upgrade path towards 3G services for operators, such as those in the USA, without access to new spectrum. Also known as Enhanced GPRS (E-GPRS)

EEPROM

Electrically Erasable Programmable Read Only Memory

EFR

Enhanced Full Rate; a alternative voice codec that provides improved voice quality in a GSM network (see codec)

EFR

Enhanced Full Rate (codec); an improved version of the standard voice codec used in GSM phones; offers improved speech quality without impacting on network capacity

EFT

Electronic Funds Transfer

EGSM

Extended (frequency range) GSM

EIR

Equipment Identity Register; a database that contains a list of all valid mobile stations within a network based on their IMEI

EIRP

EPOC

The mobile phone operating system developed by Symbian. Derived from epoch-the beginning of an era-EPOC is a 32-bit operating environment which comprises a suite of applications, customisable user interfaces, connectivity options and a range of development tools

EPROM

Erasable Programmable Read Only Memory

Erlang

A dimensionless unit of average traffic density in a telecommunications network

ERMES
