Acronym or term Definition
DCE Data Communications Equipment
A device that sits between the data terminal equipment (DTE) and a data
transmission circuit. Usually the DCE is a modem.
Diversity Antenna diversity, also called space diversity, is a scheme that uses two or more
antennas to improve the quality and reliability of a wireless link.
Often, especially in urban and indoor environments, there is no clear line-of-sight
(LOS) between transmitter and receiver. Instead the signal is reflected along multiple
paths before finally being received. Each bounce can introduce phase shifts, time
delays, attenuations, and distortions that can destructively interfere with one another
at the aperture of the receiving antenna.
EDGE Enhanced Data rates for GSM Evolution
A digital mobile phone technology that allows improved data transmission rates as a
backward-compatible extension of GSM. EDGE is considered a pre-3G radio
technology and is part of ITU's 3G definition.
Also known as Enhanced GPRS (EGPRS), or IMT Single Carrier (IMT-SC), or
Enhanced Data rates for Global Evolution.
EIA Electronics Industry Association
EIA was a standards and trade organization composed as an alliance of trade
associations for electronics manufacturers in the United States.
They developed standards to ensure the equipment of different manufacturers was
compatible and interchangeable. The EIA ceased operations on February 11, 2011,
but the former sectors continue to serve the constituencies of EIA.
EMC Electro Magnetic Compatibility
The branch of electrical science which studies the unintentional generation,
propagation and reception of electromagnetic energy with reference to the unwanted
effects (Electromagnetic interference, or EMI) that such energy may induce.
EMI Electro Magnetic Interference
The disturbance that affects an electrical circuit due to either electromagnetic
induction or electromagnetic radiation emitted from an external source.
ERP Effective Radiated Power
A standardized theoretical measurement of radio frequency (RF) energy. It is
determined by subtracting system losses and adding system gains.
ESN Electronic Serial Number
The unique first-generation serial number assigned to the LS300 for use on the
wireless network. Compare to MEID.
Ethernet Computer networking technologies for local area networks (LANs).
EU The European Union Organization of European countries.
