It is no secret that at present there is an active construction of networks of third generation mobile communication. In our country – is primarily a network standard umts. They allow you to provide subscribers with a wide range of new services: video call, video streaming, positioning, online games, high-speed Internet access (up to 14, 4 Mbps), etc. It would seem that the days were numbered and gsm networks in the near future phones this standard will be found only in museums. But do not jump to conclusions. It's safe to say that the 2G for a long time will remain in the ranks. This is due to several factors: 1. Widespread networking standard 2G.

Already functioning networks are a major source of revenue for operators and bring good income. Naturally, no one will abandon them until such time until a credible alternative. 2. The number of subscribers devices that support the umts standard the total number of not so great. Until now, most sold handsets support only the gsm standard, and, abandoning the networks 2G, the operator immediately lose most of their subscribers.

3. gsm networks provide a wide range of conventional services to subscribers: voice connections, sms, mms, conferencing, voicemail and more. so many subscribers a set of services are quite satisfied, and the use of new standard and, therefore, purchase a new phone does not matter to them, nor any sense. The question then arises: why operators make huge investments in building new networks, if a gsm network can still bring benefit to the owner and address (although to a lesser extent than 3G) subscriber demand. The answer lies in the desire of mobile operators to increase the share of income from the so-called value-added services, which, just and true data transmission. This tidbit a long time does not sleep leading players of the mobile market. Existing in gsm data transmission technology such as gprs and edge do not meet current subscriber requests for speed (Up to 384 kbit / s), and umts networks to support hsdpa technology enable Internet access at speeds up to 14.4 Mbps. This compares with wired technologies like adsl, fttb, Ethernet. Thus, cellular communication can compete with dedicated Internet access service quality, and it promises no small income for the operators, which can be comparable with the income from basic services (voice transmission). So after all, what would be the coexistence of gsm and umts in the future? In First of all it will be good neighbors. Some operators initially build a 3G network specifically for data transmission, is prohibited in their voice calls, sms and so on, allowing only access to the Internet. So manner, while conserving valuable resources of the new network for the most significant trends. At the same 2G network unloaded due to the outflow of Internet users. Over time, the network of the second and third generations will coexist as equals. The subscriber can choose for myself used a network depending on their needs and capabilities of the phone. Say the same when it will begin withdrawal from service of gsm networks is still too early. The fact that it is often advantageous operate loss-making network, as well as the dismantling of telecommunications equipment requires large funds. Therefore, at least a few years nobody will think about how to turn off the gsm network in favor of a new generation. So it is too early to get rid of your gsm phone, but it is to choose a new – umts device.
