1. EDGE TECHNOLOGY
AN EVOLUTION IN MOBILE TECHNOLOGY PRESENTED BY KIRAN KUMAR

2. AIM OF THE PRESENTATION
To familiarize the audience what EDGE
TECHNOLOGY is all about.
To explain it’s advantage over other technology.
FUTURE SCOPE of the existing technology.

3. EDGE TECHNOLOGY: What is Edge?
Enhance data rate for GSM evolution (EDGE) is
a digital mobile phone technology.
It is generally classified as a 2.75G network technology.

4. How is EDGE related to mobile phones ?
EDGE has been introduced into GSM network around the since world since 2003 initially in North American.

5. HISTORY
EDGE was adopted by UWCC in January 1998 as the outdoor component of 136HS to provide 384 kb/s data services.
This was in support of the technology evolution for GSM and TDMA/ 136 systems.
EDGE is a technology that gives GSM Networks the capacity to handle services for 3G EDGE was developed to enable the transmission of large amounts of data at peak rates of upto 472 kbps.

6. Users should experience average speeds of 80 kbps to 130 kbps
Users should experience average speeds of 80 kbps to 130 kbps. EDGE deployment will begin in 2003 with full deployment finishing in 2004.
EDGE devices are backwards compatible with GPRS and will be able to operate on GPRS networks where EDGE has not yet been deployed.

7. INTRODUCTION
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 on the move.

8. It can be used for any packet switching
application such as an internet connection.
EDGE circuit switching is a possible for
future development.
It increase data rates up to 384 kbps.
Introduces a new modulation
technique (8PSK) and channel coding.

9. HOWDOES 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 to160 kbps per user with mobile terminals.

10. ARCHITECTURE
EDGE is an improvement to the GPRS air interface that enables higher user bit rates and greater system capacity by enhancing the physical layer.
The higher bit rates place extra demands on parts of the GPRS network The core GPRS nodes, SGSN and GGSN, are more or less independent of user bit rates and no new hardware is required.

11. In the radio network, base station transceivers need to be EDGE-capable, and base station and BSC/PCU software needs to be updated.
EDGE improves the situation by employing a new modulation method and link quality control. 8-PSK is a high-level linear modulation method that carries three times more information through an extended signal constellation.

12. Impact ofEDGE on existingGSM/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

13. 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.

14. Coding schemes (modulation coding schemes

15. Measurement accuracy It is done by measuring bit error rate ,carrier
strength etc.
It has done by quickly to select the right
coding scheme.

17. DATA TRANSMISSON IN EDGE
The current GSM standard provides data services with user bit rates up to 14.4 kb/s .
Higher bit rates can be achieved with multislot operation, but since both high-speed circuit-switched data (HSCSD) and General Packet Radio Service (GPRS) .
EDGE provides high data services with user bit rates up to 59.2 kb/s.

18. EDGE modulation technique

19. Edge link controlling function
It uses a combination of 2 functionalities :
1.Link adaptation
2.Incremental redundancy

20. FUTURE OF EDGE

21. ADVANTAGES Balanced improved bit rate at all radio conditions
No hardware, software change to GSM core networks
Supports download various file types

22. Handle four times the traffic of standard GPRS
Smart & adaptive antennas
Triples gross data rate by GSM
Circuit-switched and packet-switched traffic coexist

23. ADVANTAGE OF EDGE

24. Rapid Internet and WAP access
Service available for EDGE phones without tariff charge
Avoids creating new system

25. DISADVANTAGES EDGE requires base station modifications
Extra mobile terminal hardware and software required
Frequently referred to as 2.75G

26. 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

27. EDGE allows the delivery of advanced mobile services such as the downloading of video and music clips, full multimedia messaging, high-speed Internet access and on the move.
