EDGE FULL FORM

Full Form of EDGE: Enhanced Data Rates for GSM (Global System for Mobile) Evolution

What is the full form of EDGE ?

No:1. EDGE is an enhanced version of GSM and offers high speed 3G built on GSM.
No:2. It is type of data system use on GSM network used to allow improved data transmission rates.
No:3. It can transmit three times more bits than GPRR in the same length of time.
No:4. EDGE is an “add-on” to GPRS, it cannot work alone. It was deployed on GSM networks by AT&T in 2003 in the United States.

Data Speed

No:1. EDGE has successfully replaced GSM without disrupting the existing frequency reuse scheme.
No:2. Technically, EDGE provides a speed of 384kbps (which is much higher than data rate of GPRS) but labeled as 2.75G by industry.

Key Elements added in EDGE

No:1. Use of 8PSK: Modulation format has been changed to 8PSK which provides the advantage to convey 3 bits per symbol.
No:2. Base station: Some small changes have been made in the base station.
No:3. Upgrade to network architecture: It offers IP based transfer rate which makes it necessary to add some more network elements.
No:4. Mobile stations: To use EDGE facilities, it is mandatory to gave a GSM EDGE handset because each and every set can’t be upgraded.

Features

No:1. Provide increase data rate, e.g. high speed on GSM radio carriers as provided by broadband.
No:2. It can retransmit a packet with more robust coding which means re-segmentation is possible.
No:3. In EDGE packets are address up to 2048 while in GSM it is from 1 to 128.
No:4. Similarly EDGE has a window size of 1024 and GSM window size was 64.
No:5. EDGE reduces the number of bursts to retransmit when error occurs.
No:6. It allows multimedia file transfer, web browsing and video conferencing through wireless terminals.
No:7. It enables operators to triple the data rate of subscribers and provide extra capacity to their voice communications.
No:8. It requires less radio resources to support the same traffic as supported by GSM networks.
