First, let's take a look at the speed comparison between GPRS and edge:
Network |
Speed |
Stability |
Theoretical speed |
Theoretical download speed |
Edge |
384-473kbps |
60kb/s |
Very stable |
GPRS |
171.2 kbps |
20kb/s |
Average |
From the above Parameter comparison analysis, the edge network speed is much higher than the current GPRS. In theory, the fastest speed of GPRS can reach 171.2 kbps, And the download speed is 20 kb/s. This is only a theoretical value. In practice, it is subject to restrictions and far from reaching the ideal value, so the current GPRS to cope with E-MAIL, browse WAP web page, QQ, MSN these data throughput small application feel speed is acceptable, but to use big data business, GPRS is not competent, such as browsing WWW webpages, online video on demand, video calls, data exchange, and so on.
Edge makes full use of its advantages. EDGE network theory can achieve the fastest speed of 473 Kpbs, which can basically be kept at 384 Kpbs, and the theoretical download speed can reach 60 kb/s, in terms of data, edge is three times that of GPRS. In addition, people who often use the GPRS Service experience it. When the GPRS throughput data volume is large, it is easy to cut off or even cut off, while edge stability is much more stable than GPRS.
It is worth mentioning that the uplink and downlink speeds of GPRS are the same, both of which are 20 kb/s, while the uplink and downlink speeds of edge are different, edge download speed is about 2.5 times faster than the upstream speed. For devices like mobile phones, the uplink speed is seldom mentioned, because mobile phones are not suitable for uplink use, and generally there is little data going up.
The speed of the edge network is close to that of the current 512 k adsl. for mobile phones, it can already meet the current business application requirements. In addition, edge greatly enhances the stability of data exchange.
What is the difference between actual use and theoretical value? Check out comments from netizens:
User 15: edge pull is used in Guangdong province, and atom is used. If you download a movie through the mobile phone, it will be 24-27kb/s! Accessing the Internet through ucweb is as fast as using ADSL! Generally, it takes only 5 seconds to open a page.
Netizen 19: The speed is very fast, with an average of 14 ~ 20 k per second, download fast! The maximum value is KB per second!
From the two netizens leave a message, the speed of edge network is indeed much faster than GPRS, download speed is about 30kb/S-40KB/s, although there is still a gap from the theory of 60 kb/s, it is very gratifying compared with GPRS.
Some netizens reported that although EDGE network access was used, the speed was similar to that of GPRS, and there was no obvious difference or how fast it was. Xiaobian has also tried surfing the Internet in EDGE networks. The speed is indeed not much different from that of GPRS, as reflected by many netizens. In fact, edge uses a new modulation method in the GSM system, which can be expanded from 2 to 8, and the speed will change according to the modulation, although the network has been switched to the edge network, the speed is not adjusted, so the speed will be similar to the current GPRS.
To put it simply, EDGE networks have a faster transmission speed than GPRS, almost three times that of GPRS, which can meet the requirements of current information exchange, Web browsing, online video on demand, and video calls, data sharing and other high-throughput data services.
