Can the enhanced edge extend the GSM long tail?

Recently, a well-known consulting company revealed that Sony Ericsson will be in Barcelona MWC2010 on the introduction of enhanced edge mobile phones, domestic operators are already doing related network testing.　　The person is also very optimistic about the enhanced edge of the mobile phone in the domestic market prospects. According to the reporter understand, because of the rapid development of 3G, foreign operators do not have much to do with this technology, and China Mobile has started testing the enhanced edge network in some areas, the network rate has been greatly improved, but this conclusion does not apply to all, the technology that matured two years ago,　　Whether to start a new round of development in China is still unknown. The speed can be comparable with the 3G enhanced edge is further deepened in the GSM network, the greatest advantage of this technology is no need for network architecture changes, only to be in the wireless side of the corresponding upgrade, without increasing the burden of the original GSM network, can reach up to 1~6mbit/s air interface rate. According to the introduction, as a mobile data communication technology of GSM to LTE, the enhanced edge technology introduces 3G part of technology to 2G network, the data rate is more than the existing GSM network, the network delay, the service quality (QoS) and so on have been greatly improved, and the user experience has been greatly enhanced. In the near future, most of the existing 3G data services can be in the edge network to get good support.　　and enhanced edge so that the original GSM network can continue to deepen development, greatly protect the existing operators and users of resources, can be used as 3G and 3.5G technology to supplement the effective and from GSM to LTE transition technology. Recently, Huawei announced its use of edge+ technology to refresh the GSM network data rate of the fastest record, the average rate reached 564kbit/s, is the current edge network rate of twice times, reached the level of the early 3G.　　Ericsson also said to the Economist, Ericsson and China Mobile in Guangdong, the Enhanced Edge Network test has been completed, through software upgrades, the rate has reached more than 550kbit/s, with further upgrades, the expected rate of 1mbit/s. Can effectively complement TD terminal needs to be updated it is reported that Huawei and Ericsson have been with China Mobile for enhanced edge network related testing and verification. "But large-scale business also needs the operator's clear stance." "A certain device trader said. In other words, China Mobile has not yet a clear attitude towards the wider deployment of enhanced edge. The person said that the GSM network upgrade to the enhanced edge, technology is not a problem, the first phase is a software upgrade, the follow-up may need to make some changes to the hardware, for operators, the current 2G investment gradually decline, 3G investment is the focus,　　Therefore, the prerequisite for the large-scale deployment of enhanced edge is to coordinate the relationship between the cost of network upgrades and the benefits. "We validated the deployment of enhanced edge at the end of 2009," said a local mobile company.From the results, the higher the cost, so the suspension of the relevant research, the next plan also depends on the planning of China Mobile headquarters.　　"It is understood that the area of GSM network equipment is older, only through software upgrades to reach the requirements, hardware must be replaced, so you can not guarantee the benefits of the network upgrade." In addition to network problems, the terminal is another big problem, users must replace the terminal to be used in the enhanced Edge network, which is a huge expense to users and operators.　　At the same time, the type of enhanced edge terminals is relatively small, it is understood that only the BlackBerry and Sony Ericsson launched the corresponding terminals, other manufacturers are still watching. In addition, during the interview, most experts agree that China Mobile's deployment of enhanced edge is a useful complement to TD. The above equipment business people think, from the current TD user development situation, it is necessary to develop enhanced edge. Ericsson said that enhanced edge and TD can promote each other, and can improve business fluency and continuity, effectively improve the user experience.　　A Telecommunications Research institute also said that China Mobile wireless resources are relatively rich, and TD's data has yet to be upgraded, enhanced edge is a very sophisticated technology, speed and TD comparable, therefore, enhanced edge for TD is a good remedy. Links: Enhanced Edge Evolution Route edge The first phase of the standardization work EDGEPhase1 included in the 3GPP R99, followed by the GSM standardization work moved from ETSI to 3GPP.　　Edge Phase II (included in 3GPPR4, R5) further improve and improve voice and data services. Starting from R7, 3GPP began to discuss the way of using WCDMA to introduce HSPA to further strengthen GSM's data service support capability. April 2007, R7 involves strengthening the edge of the key technology to determine.　　At the end of 2007, R7 version of the freeze, marking the enhanced edge of the standard has become mature. Beginning in 2008, R8 version began to explore the edge of long-term evolution (Geranlte).
