| EDGE (Enhanced Data rates for GSM (Global) Evolution) |
EDGE is a faster version of GSM wireless service. EDGE
enables data to be delivered at rates up to 384 Kbps on
a broadband. The standard is based on the GSM standard
and uses TDMA multiplexing technology. |
| EMS (Enhanced Messaging Service) |
EMS adds the ability to attach simple graphics, pictures,
animations and sound to SMS messages. |
| E-Mail |
The electronic transfer and storage of written messages. |
| E-OTD (Enhanced Observed Time Difference) |
E-OTD is a method used for determining mobile station
location in terms of universal latitude and longitude
coordinates. The E-OTD positioning method is calculated
by the differences in arrival time of signals from nearby
pairs of mobile phone towers. |
| Electronic Lock |
When activated the mobile phone will automatically lock
each time it is turned off to help prevent unauthorized
use. |
| Electronic Scratchpad |
Allows users to use their phone keypad to type and save
numbers into their phone during a call and to also save
that information. |
| ESN (Electronic Serial Number) |
ESN is a unique unchangeable number that is built into
the phone and is transmitted by the phone as a means of
identifying itself within the system. |
| Emergency One-Touch Dialing |
A memory location reserved for storing an important
number. The number can be accessed and called even if
the phone is locked. |
| Error Correction |
Digital technology's ability to verify the validity
of the transmitted information and to automatically correct
errors caused by interference. |
| Feature Menu |
Allows easy access and activation of frequently used

a Push To Talk session. |
| Fold-Down Antenna (transportables); |
The design of the transportable's antenna allows it
to swivel 360 degrees and fold flat in any direction,
providing convenient storage. |
| Frequency Reuse |
Technology that allows frequencies to be reused after
they have been vacated by a cellular user leaving that
particular cell. One measure of a system's effectiveness
is how far the initial user of a specific frequency must
travel away from the cell site before the frequency may
be reused.
Fringe Area The outermost range of a cellular system where
cellular signals may be weaker.
Full Duplex Incoming and outgoing audio can occur simultaneously,
so user can speak and listen at the same time.
Function Keys The non-numeric keys on your phone used
to access and navigate menu features, as well as perform
memory functions.
