| Term | Description |
| DAMA | Demand Assigned Multiple Access. |
| D-AMPS | Digital AMPS, a US wireless standard also known as IS-136. |
| DAN | DECT Access Node. |
| DB | Dummy Burst; transmitted as a filler in unusual timeslots of the carrier. |
| DCA | Dynamic Channel Assignment. |
| DCCH | Dedicated control channels; responsible for roaming, handovers, encryption, etc. (See SDCCH, SACCH and FACCH). |
| DCE | Data Communications Equipment. |
| DCH | Data Clearing House. |
| DCS1800 | Digital Cellular System at 1800MHz, now known as GSM1800. |
| DES | Digital Encryption Standard. |
| DFSK | Double Frequency Shift Keying. |
| DHCP | Dynamic Host Configuration Protocol. GSN Lite product contains a DHCP-client module, which interacts with the DHCP-server to allocate dynamic addresses while executing dynamic PDP context activation and deactivating contexts on explicit MS request or expiry of lease time for dynamic address so obtain. |
| Digital | A method of representing information as numbers with discrete values; usually expressed as a sequence of bits. |
| Downlink | The transmission path from the base station down to the mobile station. |
| DPCM | Differential Pulse Code Modulation. |
| DPSK | Digital Phase Shift Keying. |
| DS-CDMA | Direct Sequence DCMA. |
| DSP | Digital Signal Processing. |
| DSRR | Digital Short Range Radio; a UK standard for a low power, short range radio system designed for small voice and data networks. |
| DTE | Data Terminal Equipment. |
| DTMF | Dual Tone MultiFrequency; better known as a Touch Tone. The tones generated by touching the keys on the phone are used for a variety of purposes including voice mail systems and voice messaging. |
| DTZ | Discontinuous Transmission. |
| Dual Band | The capability of GSM infrastructure elements and handsets to work across both the 900 MHz and 1800 MHz bands. The capability to seamlessly handover between the two bands offers operators major capacity gains. |
| Duplex | The wireless technique where one frequency band is used for traffic from the network to the subscriber (the downlink) and another, widely separated, band is used for traffic from the subscriber to the network (the uplink). |
| EDGE | Enhanced Data rates for GSM Evolution. A technology that gives GSMA and TDMA similar capacity to handle services for the third generation of mobile telephony. EDGE was developed to enable the transmission of large amounts of data at a high speed, 384 kilobits per second. (It increases available time slots and data rates over existing wireless networks.) Also known as Enhanced GPRS (E-GPRS). |
| EFR | Enhanced Full Rate; an alternative voice codec that provides improved voice quality in a GSM network (see CODEC). |
| 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. |
| Encryption | cryptographic technique utilizing a digital key to scramble and hence "lock data in such a manner that it cannot be descrambled and decoded without the key. |
| 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, customizable user interfaces, connectivity options and a range of development tools. |
| ERLANG | A dimensionless unit of average traffic density in a telecommunications network. |
| ERMES | Enhanced Radio messaging System; a paging technology developed by ETSI that was intended to allow users to roam throughout Europe. Adopted by a number of European and Middle Eastern countries, ERMES, like paging in general, was overtaken by the ubiquity of GSM. |
| ERO | European Radiocommunications Office. |
| ERP | Effective Radiated Power. |
| Error correction | The process of correcting errors in data transmitted over a radio channel using forward error correction (FEC) techniques. |
| ESMR | Enhanced Special Mobile Radio; a US PMR variant (see SMR). |
| ESN | Electronic Serial Number; a 32-bit number that uniquely identifies a mobile phone. |
| ETS | European Telecommunications Standard. |
| ETSI | European Telecommunications Standards Institute the European group responsible for defining telecommunications standards. |
