Enhancements in Releases R’98 and R’99 meant that GPRS could theoretically reach downlink speeds of up to 171Kbps. EDGE… almost 3G In view of this, it is found that when the signal is poor GMSK can be more effective than 8PSK, and as a result, the overall EDGE modulation scheme is a mixture of GMSK and 8PSK. GSM EDGE time slots EDGE, GPRS and GSM have to all operate along side each other in a network. Hello friends, here is the link to my new UDEMY Course on 5G Technologies, Architecture And Protocols and all other courseshttps://drmoazzam.com/udemy-course EDGE, also known as Enhanced Data for Global Evolution or Enhanced GPRS, is a backward-compatible extension of GSM introduced in the market in 2003. Built upon the GSM network, EDGE is faster than its older version GSM. GSM network is classified as 2G network, while EDGE is known as 2.75G although it completes the requirements of 3G network. EDGE (Enhanced Data Rates for GSM Evolution) enhances the GSM standard with a new modulation format (3 /8 8PSK) and filtering designed to provide higher data rates in the same spectrum. EDGE has also been adopted as the basis for IS-136HS (NADC).
Edge, compared to standard GSM and. TDMA/136 modulations (Box B, Equations. , and the results indicate that EDGE can share the same spectrum as GSM/GPRS with good quality for both types of users.

In EDGE packets are addressed up to 2048 and window size to 1024. In GPRS packets were numbered from 1 to 128 and addressing window size was 64. This page GSM versus GPRS describes difference between GSM and GPRS technologies. • Air interface is same TDMA/FDMA. • In GPRS multiple timeslots are allocated to one UE while in GSM one timeslot is allocated to one UE. • In GSM signaling and traffic follow different multi frame structure. 51 frame MF is used for signaling and 26 frame MF
GPRS is an upgrade over the basic features of GSM. It allows mobile handsets to obtain much higher data speeds than what standard GSM can offer.

GSM and GPRS are inter-related technologies.
EDGE followed GPRS and increased the maximum download speed to 384 kbps. When the original GSM (Global System for Mobile Communications) networks were launched in the early 1990s, they only had the circuit-switched (CS) capability.

While considering the communication rates in both networks, GPRS offers cheap data charges than GSM. GSM allows only short messages for communication
384 kbit / s) than with the wireless standard of the second generation (2G ), the GSM standard (up to 220 kbit / s in EDGE;.
