Mobile Technologies

Currently, mobile technologies are being introduced more deeply into people's lives. Existing standards provide consumers with not only voice calls and transmit SMS. There is a growing multi-media services and are data services. And the cost of the latter is gradually approaching the cost of wired Internet access via leased lines. Also, thanks to the emergence of 3G data transfer rates equal the existing technologies to the wired Internet access. (A valuable related resource: Bobby Green). This gives a big boost to a significant increase in volumes of packet data in the future. However, today provided the data rate will meet subscriber needs to 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 greater bandwidth. All this will eventually lead to the fact that the 3G network will not meet the needs 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 in the next few years, in 2004 began development of a standard mobile fourth generation – LTE (Long Term Evolution). Work on it is an organization 3GPP (3rd Generation Partnership Project). At the very beginning of the cornerstone principles were as follows: Increase the system capacity and reducing the cost per bit informatsii.Dostizhenie much higher data rates than existing third-generation systems. Target: At least 50 Mbit / sec – uplink (from phone to base station), 100 Mbit / sec – downlink (from base station to the phone).

More coverage due to the use of higher data rates to a broader area of coverage and flexibility in the use of frequencies involved systems 2G and 3G, and new frequency diapazonov.Dostizhenie higher system capacity, up to 3 times compared to existing systems – more services at less cost to the subscriber. By May 2010 have been released tenth release standard LTE-Advanced. The prefix 'Advanced' was added after were combined efforts of two organizations: 3GPP and IMT-2000, which developed a standard of IMT-Advanced. The world's first commercial cellular network was launched LTE standard at the end of 2009 in Sweden. It is already known that many operators in developed countries are planning to launch LTE network in the next 2-3 years, including Russia. Our country is an auction, which were raffled off frequency for the standard networks. Some operators have started testing LTE. If talk about the equipment for networking standard LTE, most of the leading companies specializing in the production of telecommunications equipment, are already offering solutions for cellular operators. In addition, the market Cell phones are emerging models that support this standard. It's safe to say that in the next few years appear adequate choice of subscriber equipment at an affordable price, because Manufacturers have felt the promise of the standard and try to fill in time before the arrival of market competition. Thus, LTE – a fourth-generation standard. Cellular network, built on the standard provide data transmission at speeds of several hundred megabits per second (Rel.10 – 324 Mbit / sec) have a high capacity and efficiency. All this gives grounds to say that LTE networks are very promising, as one solve the problem of the operator and the other at a sufficient level satisfy the needs of customers for the long term.
