AIM OF THE PRESENTATION

To familiarize the audience what EDGE

TECHNOLOGY is all about.

To explain its advantage over other technology.

FUTURE SCOPE of the existing technology.

EDGE TECHNOLOGY:

What is Edge?

How is EDGE related to mobile phones ?

3rd generation mobile communication.

EDGE Technology

Evolutionary path to 3G services for GSM and TDMA

operators

Builds on General Packet Radio Service (GPRS) airinterface and networks

Phase 1 (Release99 & 2002 deployment) supports best

effort packet data at speeds up to about 384 kbps

Phase 2 (Release2000 & 2003 deployment) will addVoice over IP capability

EDGE Airlink

Extends GPRS packet data with adaptive

modulation/coding

2x spectral efficiency of GPRS for best effort data

8-PSK/GMSK at 271 ksps in 200 KHz RF channels supports8.2 to 59.2 kbps per time slot

Supports peak rates over 384 kbps

Requires linear amplifiers with < 3 dB peak to average

power ratio using linearized GMSK pulses

Initial deployment with less than 2x 1 MHz using 1/3 reuse

with EDGE Compact as a complementary data service

Requirements on EDGE

EDGE- and non-EDGE-capable mobile stations should beable to share one and the same time slot.

EDGE- and non-EDGE-capable transceivers should be

deployable in the same spectrum.

A partial introduction of EDGE should be possible.

It was so decided that two classes of terminals should be

supported by the EDGE standard:

A terminal that provides 8PSK capability in the downlink

only, and

A terminal that provides 8PSK in the uplink and downlink.

Advantages Balanced improved bit rate at all radio conditions

No hardware, software change to GSM core networks

Supports download various file types

ABHIRAM 13


14/18

Handle four times the traffic of standard GPRS

Smart & adaptive antennas

Triples gross data rate by GSM

Circuit-switched and packet-switched traffic coexist

ABHIRAM 14


15/18

Rapid Internet and WAP access

Service available for EDGE phones without tariff charge

Avoids creating new system

ABHIRAM 15


16/18

DISADVANTAGES: EDGE requires base station modifications

Extra mobile terminal hardware and software required

Frequently referred to as 2.75G

ABHIRAM 16


17/18

CONCLUSION: EDGE technology has succeeded the technology

previously used in mobile phones.

Low risk of investment thanks to the dual mode of

GSM/EDGE (Slot by slot) It support the same technology as GPRS but it has got

higher data rates of more than 400kbits/sec

EDGE allows the delivery of advanced mobile services

such as the downloading of video and music clips, fullmultimedia messaging, high-speed Internet access ande-mail on the move.
