EDGE: Enhanced Data Rate for Global Evolution is an evolutionary step in the GSM-development path for faster delivery of data, delivered at rates up to 384 Kbps. The standard is based on the GSM technology platform and uses the TDMA approach (see TDMA, below).
 
ESMR (Enhanced Specialized Mobile Radio): A single wireless device that combines a two-way radio, phone, mobile dispatch, radio paging and Mobile data capabilities, and operates on digital networks.   Examples of ESMR service providers include Nextel Communications, Nextel Partners, and Southern LINC Wireless, among others.
 
ESN (Electronic Serial Number): The unique serial identification number programmed into a wireless phone by the manufacturer. Each time a call is placed, the ESN is transmitted to a nearby base station so the wireless carrier can validate the call.  The ESN differs from the Mobile Identification Number, which identifies a customer’s wireless phone number.  MINs and ESNs are electronically monitored to help prevent fraud.

Evolution-Data Optimized (EV-DO): A wireless radio broadband data standard adopted by CDMA mobile service providers in United States, and other countries.  EV-DO is aimed at delivering maximum downlink speeds of 3.1 Mb/s.

Federal Regulatory Fee: Annual communications regulatory fees as mandated by Congress.  The fees require the FCC to recover the regulatory costs associated with its enforcement, policy and rulemaking, user information, and international initiatives.
 
FDD (Frequency Division Multiplexing): Frequency-division multiplexing is a method in which numerous signals are combined for transmission on a single communications channel. Each signal is assigned a different frequency (subchannel) within the main channel.
