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.

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.

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

1.It can be used for any packet switching application such as an internet connection. 2.EDGE circuit switching is a possible for future development.

EDGE (Enhanced Data Rate for GSM

Evolution)

Increase data rates up to 384 kbps

Introduces a new modulation technique (8PSK) and channel coding.


Evolution)

EDGE modulation technique

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.


Evolution)

Coding schemes (modulation coding schemes)


Evolution)

Measurement accuracy

It is done by measuring bit error rate ,carrier strength …etc.

It has done by quickly to select the right coding scheme.


Evolution)

Edge link controlling function It uses a combination of 2 functionalities :

1. Link adaptation

2. Incremental redundancy

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.


Evolution)

EDGE benefits Short-term benefits: Capacity and

performance Easy implementation on a

GSM/GPRS network Cost effective Increase the capacity and triples

the data rate of GPRS Enabling new multimedia services

Long-term benefit: Harmonization with WCDMA


Evolution)

Impact of EDGE on existing GSM/GPRS networks

Hardware upgrade to the BSS (new transceiver in each cell)

Software upgrade to the BS and BSC No change in the core networks New terminals - Terminal which provides 8PSK in the

uplink and the downlink - Terminal which provides GMSK in the

uplink and 8PSK in the downlink

(And more economical)

ADVANTAGES OF EDGE

1. Faster data transfer rates up to 384 kbps

EDGE TECHNOLOGYTODAY TECHNOLOGY

Higher data throughput
