A considerable number of people are wondering what is LTE. This progressive technology is officially called 3GPP Long Term Evolution for Universal Mobile Telecommunications System (3GPP UMT LTE). The wireless broadband technology is designed to permit roaming internet access for handheld devices, such as mobile phones, tablets and laptops. It has been developed with many improvements over the former mobile communication standards. The forum responsible for its growth and standardisation is the Third Generation (3G) Partnership Project.
The 3GPP was established during December of 1998. Its participants belong to worldwide based telecommunications companies which are known as the Organisational Partners. The first remit of the 3GPP was to develop 3G mobile phone systems which were universally applicable. Since its inception, the scope of its duties have grown.
Presently, the 3GPP is responsible for maintaining and developing three main technological areas. Among them are the GSM (Global Systems for Mobile Communications), which includes the evolution of radio access technologies. It is also accountable for the evolved 3G and beyond mobile networks which are based upon the 3GPP core systems. The group also supports evolved IMS (IP Multimedia Subsystems) which are access-independent.
The LTE technology can be put to use with ease and can supply high data rates with low latencies across very long distances. Known as 4G (fourth generation), it is superior over 3G systems. For instance, initial readings show the 4G network can easily attain data download speeds of nearly 16 Mbps, as opposed to just over 1 Mbps for 3G connections. The mean upload speed for the 4G system is about 1.5 Mbps, compared with 0.7 Mbps for the 3G.
LTE networks are much simpler to make use of than its predecessors. Its network architecture is considerably simpler because it is merely a network that is packet switched. The system does not possess the ability to handle text messages and voice calls natively. Those types of services are usually controlled by networks that are circuit-switched, such as GSM and CDMA (Code Division Multiple Access).
The Simplified Architecture Evolution (SAE) of the LTE is essentially a simpler version of the architecture which is currently utilised by the Universal Mobile Telecommunications Systems (UMTS). The UMTS dictates a comprehensive network system which encompasses the Universal Terrestrial Radio Access Network (UTRAN), along with the core Mobile Application Part (MAP) network. It also certifies users through their Subscriber Identity Module (SIM) cards.
The new 4G system is dependent upon two kinds of radio links. The downlink moves from the tower to the device, and the uplink moves from the device to the tower. Since two separate kinds of interfaces are utilised, wireless communications in both directions are optimised.
The downlink technology is considerably more advanced than both the CDMA and the TDMA (Time Division Multiple Access), which have been in use since 1990. The recently developed radio interface is known as the Orthogonal Frequency Division Multiple Access (OFDMA). It orders that multiple in-multiple out (MIMO) technology is utilised. That means a device has multiple connections to each cell, which enhances the stability of each connection and reduces its dormancy greatly.
For the uplinks, a scheme known as DFTS-OFDMA (Discrete Fourier Transform Spread, Orthogonal Frequency Division, Multiple Access) is utilised. It produces a superior Single Carrier Frequency (SC-FDMA) signal. Among other things, it has a greater power ratio for uplinking.
There are two subcategories within the LTE technology: the TDD (Time Division), and the FDD (Frequency Division. The most common variation is the FDD. It relies on separate frequencies for uplinks and downlinks in the form of band pairs. As a result, each band supported by a phone consists of two different frequency ranges. The TDD variation depends upon a single frequency range within a band. This band is divided into segments in order to support both the reception and transmission of signals in its single frequency range.
Wimax is an existing technology that relies upon underlying wireless (wi-fi) networks. By contrast, within the UK, LTE is founded on the same type of technology which is currently used by the UK's 3G network. For that reason, the UK plans to utilise the 4G LTE technology instead of Wimax.
Understanding what is LTE can aid consumers make educated buying choices. Selecting new devices which support 4G networks are wise decisions. This technology is expected to command worldwide telecommunications for many years.
