E-UTRAN - Evolved UMTS Terrestrial Radio Access Network - A new radio interface specified by the 3GPP consortium and introduced with LTE in 2008. It was designed to meet ever-increasing data transfer rates while reducing the radio operation latency.
EIRP - Effective Isotropic Radiated Power - An IEEE standardized definition for the measurement of the radiated power of an antenna in a specific direction.
eLTE eNB - An evolved 4G eNodeB (or eNB) that can support connectivity to the 4G evolved packet core (EPC) as well as the 5G next- generation core network (NGC or NGCN).
eMBB - Enhanced Mobile Broadband - One of three primary use cases defined in the IMT-2020 vision. Enhanced Mobile Broadband refers to target 5G peak and average data rates, capacity, and coverage as compared to conventional mobile broadband (MBB). eMBB specifies a 5G design capable of supporting up to 20 Gbps in the downlink, and 10 Gbps in the uplink.
EN-DC – E-UTRAN New Radio – Dual Connectivity - A term for the simultaneous 4G LTE and 5G NR connectivity prescribed by 3GPP Release 15. EN-DC enables user equipment to connect simultaneously to an LTE base station and a 5G base station.
eNB - Evolved Node B - An Advanced Base Transceiver Station (BTS) with an integrated controller, allowing for faster response times
EPC - Evolved Packet Core - The core network of the 4G LTE system, the EPC features a flat architecture to handle voice and data efficiently. It requires a few network nodes to be involved in the handling of traffic. EPC serves as an anchor in initial implementations of 5G fixed wireless access (FWA).
EPS - Evolved Packet System - Evolved end-to-end-architecture composed of the base station and evolved packet core (EPC) that enables 4G mobile communication.
ERAN - Enterprise Radio Access Network - RAN consists of small cell network platform used to densify carrier networks
ERTA - Extended Range Transmission Analysis - A technique used to measure the scalar transmission gain or loss of an RF system.
EVM - Error Vector Magnitude - Error vector magnitude is a measurement used to quantify the quality of a digital radio signal. The measurement is a representation of how far the actual signal deviates from an ideal representation of that same signal.
