1. What Is Technology
Technology is the technical means
people use to improve their surrounding.
It is also the knowledge of using the tools and
machines to do task.
2. What Is EDGE
Edge (Enhance data rate for GSM evolution) is a
radio signaling technology for 3G mobile
networks.
EDGE use for mobile service such as
downloading of video and music clips full
multimedia messaging high-speed colors
internet access and e-mail on the move.
3. Introduction Of EDGE
Enhance data rate for GSM evolution (EDGE) is
a digital mobile phone technology.
It is generally classified as a 2.75G network
technology.
EDGE has been introduced into GSM network
around the since world since 2003 initially in
North American
4. It can be used for any packet switching
application such as an internet connection.
EDGE circuit switching is a possible for future
development.
6. Increase data rates up to 384 kbps
Introduces a new modulation technique (8PSK)
and channel coding.
7. Transmission techniques
In addition to Gaussian minimum-shift keying
(GMSK), EDGE uses higher-order PSK/8 phase
shift keying (8PSK)
EDGE produces a 3-bit word for every change in
carrier phase.
9. EDGE
Measurement accuracy
It is done by measuring bit error rate ,carrier
strength …etc.
It has done by quickly to select the right coding
scheme.
10. EDGE
Edge link controlling function
It uses a combination of 2 functionalities :
1. Link adaptation
2. Incremental redundancy
11. HOW DOES EDGE WORK ?
Edge work by improving the signaling interface
used to communicate over the radio wave.
Typically edge enhance thee time the
performance of GPRS achieving an data rate 80
to 160 kbps per user with mobile terminals.
12. EDGE
EDGE benefits:
Short-term benefits: Capacity and performance
1. Easy implementation on a GSM/GPRS
network.
2. Cost effective.
3. Increase the capacity and triples the data rate
of GPRS.
4. Enabling new multimedia services.
Long-term benefit: Harmonization with WCDMA
