EDGE

An EDGE over GPRS…
The EDGE
EDGE, or the Enhanced Data Rate for Global Evolution, is the new mantra in the Global Internet Connectivity scene. EDGE is the new name for GSM 384. The technology was named GSM 384 because of the fact that it provided Data Transmission at a rate of 384 Kbps. It consists of the 8 pattern time slot, and the speed could be achieved when all the 8 time slots were used. The idea behind EDGE is to obtain even higher data rates on the current 200 KHz GSM carrier, by changing the type of the modulation used.

Now, this is the most striking feature. EDGE, as being once a GSM technology, works on the existing GSM or the TDMA carriers, and enables them to many of the 3G services.
Although EDGE will have a little technical impact, since its fully based on GSM or the TDMA carriers, but it might just get an EDGE over the upcomming technologies, and ofcourse, the GPRS. With EDGE, the operators and service providers can offer more wireless data application, including wireless multimedia,e-mail (Web Based), Web Infotainment, and above all, the technology of Video Conferencing.
Now all these technologies that were named earlier, were the clauses of the IMT-UMTS 3G Package. But, with EDGE, we can get all these 3G services on our existing GSM phones, which might just prove to be a boon to the user.

The Big Fight…
The current scenario clearly states that EDGE will definitely score higher than GPRS. The former, allows its users to increase the data speed and throughput capacity, to around 3-4 times higher than GPRS.
Secondly, it allows the existing GSM or the TDMA carriers to give the sophisticated 3G services. And with 1600 Million subscribers of GSM in over 170 countries, offer the full Global Roaming, anywhere between India to Japan and to San Fransisco.
Based on an 8 PSK modulation, it allows higher bit rate accross the air Interface.
One Symbol for every 3 bits. Thus, EDGE Rate = 3x GPRS Rate.
_________________________________
If one looks at these features, the thinking can’t be stopped that really, EDGE is over GPRS, but this is the time where the IMT-UMTS come into action. The technology that is providing Always On feature of the Internet, and an excellent billing sub-system, clearly shall be preferred for 3G. The technology has to change, and its a matter of time, when it takes over. Thus, the point here is that GSM has to go, and we must be ready for the final Adieu!

What is EDGE?
EDGE (Enhanced Data Rates for Global Evolution) is a technology allowing fast data transfer within GSM network. GRAMEENPHONE network configuration ensures EDGE with the speed of up to 236 kbps, which is 3 times faster than data transfer rate offered by GPRS technology. EDGE can be considered as a transition to 3G technology, which in its turn, offers the subscribers of mobile networks the possibility to benefit from certain 3G services, as for instance, high speed access to Internet, audio/video streaming, video file download, etc. Many mobile telephony operators consider EDGE an economic alternative for 3G technology.
What advantages are offered by EDGE?
The biggest advantage of EDGE technology is the possibility of rapid data transfer execution, which ensures a convenient, efficient, and rapid access to Internet and WAP, as well as fast sending/reception of MMS messages, thus offering the subscribers the opportunity of reaching a higher level of mobility and productivity. In addition, EDGE offers GRAMEENPHONE clients the opportunity of using the most advanced services like: audio/video streaming, video files download, etc. For the owners of EDGE-compatible phones who use GPRS services the churn to a new technology will be an easy and smooth process. These models of phones turn to the new technology automatically within the existing EDGE network without the need of supplementary settings.

Several examples of different file types downloaded by means of GPRS and EDGE are presented below:

…………………………….Size                                GPRS                                                 EDGE
E-mail Message            10 KB                            1.5 sec                                                0.5 sec
Web Page                       8 KB                              1.2 sec                                                0.4 sec
Text File                        40 KB                               6 sec                                                    2 sec
Word/Excel File           2 MB                                 5 min                                                   1 min 40 sec
Video/MP3 File            4 MB                               10 min                                                  3 min 20 sec

Note: The download speed may vary due to the terminal restrictions or network availability.
Who can benefit from EDGE?
Any GRAMEENPHONE subscriber owning an EDGE-compatible phone set up for GPRS and being in EDGE coverage area can benefit from this service.

What is EDGE coverage?
You can check the availability of EDGE by activating CELL INFO on your mobile phone. In the region covered by EDGE, the GPRS/EDGE sign will be indicated on the screen of your mobile phone.
I have an EDGE-compatible phone. Do I need to make additional settings?
In case your phone is set for GPRS, you do not need to make any other additional settings.

Is my phone EDGE-compatible?
You can find the list of EDGE-supporting terminals below. Additional information can be found in the User’s Guide of your phone or on the provider’s web site.

What transfer speed can be achieved by means of EDGE-based services usage?
EDGE speed is approximately 3 times higher than the speed of GPRS and can reach up to 236 kbps. The actual connection speed may be lower due to telephone characteristics and network availability.
What EDGE-based services can I benefit from?
By means of EDGE you can benefit from WAP, MMS, and MMI, content download (melodies and logos), which are also available by means of GPRS.
How is EDGE charged?
There are no additional tariffs for EDGE usage. Internet and WAP via EDGE is charged the same way as via GPRS.
MMS is charged on a per-message basis. EDGE is a supplimentary platform for GPRS (EDGE being sometimes called accelerated GPRS) and therefore, all services are available for EDGE phones without any tariff charge. Thus, you have more advantages for the same money.
