Currently, mobile technologies are introduced deeper into people's lives. Existing standards provide consumers with not only voice calls and transmit sms. To know more about this subject visit Jill Schlesinger. Becoming more common finds multimedia services and data services. And the cost of the latter is gradually approaching the cost of wired Internet access via a dedicated line. In addition, thanks to the emergence of 3G data transfer rates equal the existing technologies wired Internet access. For even more opinions, read materials from Andi Potamkin. This gives a big push to significantly increase the volume of packet data in the future. However, today provided the data rate will meet subscriber demand in the long run only a few years ahead. Amount of data transmitted over telecommunications networks, communication is constantly increasing.
New services provided by operators Cellular also require the expansion of bandwidth. All this will eventually lead to the fact that 3G networks will not meet the demands of customers in the coming decades and will require a new standard for high-speed wireless mobile communications. In order to create a cellular network, which would satisfy the needs and subscribers, and operators for several years, in 2004 began development of a standard mobile fourth generation – lte (Long Term Evolution). Work on it leads the organization 3GPP (3rd Generation Partnership Project). Already at the beginning of the cornerstone were placed the following principles: Increase the system capacity and reducing cost per bit of information. Achievement much higher data rates than existing third generation systems.
Purpose: At least 50 Mbps – uplink (from phone to base station), 100 Mbps – downlink (base station to the phone). More coverage through the use of higher data rates at a wide range of coverage and flexibility in the use of frequencies involved systems 2G and 3G, and new frequency bands. Achievement higher system capacity up to 3 times compared to existing systems – more services at less cost to the subscriber. By May 2010 had already been released on the tenth release of the standard LTE-Advanced. The prefix 'Advanced "was added after both were combined effort of two organizations: 3GPP and IMT-2000, which developed a standard of IMT-Advanced. The world's first commercial cellular network lte standard was launched in late 2009 in Sweden. We already know that many operators in Developed countries are planning to launch lte network in the next 2-3 years, including Russia. In our country, already an auction, which were raffled off frequencies for networks of this standard. Some operators have started testing of lte. If we talk about hardware for networks of standard lte, then most of the leading companies specializing in the production of telecommunications equipment, are already offering solutions for cellular operators. Except addition, the cell phone market already emerging models that support this standard. It's safe to say that in the next few years will be enough choice of subscriber equipment at an affordable price, because manufacturers have felt the prospects of the standard and try to have time to fill the market before the arrival of competitors. Thus, lte – the standard for the fourth generation. Cellular network, built on the standard, providing data transmission speeds of several hundred megabits per second (Rel.10 – 324 Mbps), have high capacity and efficiency. All this gives grounds to say that lte networks are very promising, so how to solve problems on the one hand the operator and the other at a sufficient level satisfy customer requests for the long term.
