A great many consumers are wondering what is LTE. This emerging technology is officially called 3GPP Long Term Evolution for Universal Mobile Telecommunications System (3GPP UMT LTE). The wifi broadband technology is designed to grant roaming internet access for handheld devices, like mobile phones, tablets and laptops. It has been developed with a number of enhancements over the previous mobile communication standards. The forum accountable for its evolvement and uniformity is the Third Generation (3G) Partnership Project.
The 3GPP was founded during December of 1998. Its participants belong to internationally based telecommunications associations which are known as the Organisational Partners. The first remit of the 3GPP was to evolve 3G mobile phone systems which were universally applicable. Since its launch, the scope of its duties have increased.
At the moment, 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 simply and can supply fast data rates with low latencies across great distances. Known as 4G (fourth generation), it is better over 3G systems. For instance, preliminary results show the 4G network can easily reach data download speeds of almost 16 Mbps, compared 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 easier to make use of than its predecessors. Its network architecture is considerably simpler because it is only a network that is packet switched. The system does not possess the capability to handle text messages and voice calls natively. Those kinds of services are mainly handled by networks that are circuit-switched, such as CDMA (Code Division Multiple Access) and GSM.
The Simplified Architecture Evolution (SAE) of the LTE is basically a simpler version of the architecture which is currently used by the Universal Mobile Telecommunications Systems (UMTS). The UMTS dictates a comprehensive network system which includes the Universal Terrestrial Radio Access Network (UTRAN), along with the core Mobile Application Part (MAP) network. It also authenticates users through their Subscriber Identity Module (SIM) cards.
The recent 4G system is dependent upon two kinds of radio links. The downlink travels from the tower to the device, and the uplink travels from the device to the tower. Because two separate types of interfaces are used, 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 used since 1990. The newly developed radio interface is known as the Orthogonal Frequency Division Multiple Access (OFDMA). It mandates that multiple in-multiple out (MIMO) technology is utilised. This means a device has several connections to each cell, which enhances the stability of each connection and lessens its latency hugely.
For the uplinks, a project known as DFTS-OFDMA (Discrete Fourier Transform Spread, Orthogonal Frequency Division, Multiple Access) is used. It produces a superior Single Carrier Frequency (SC-FDMA) signal. Among other elements, 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 more usual type is the FDD. It relies on different frequencies for uplinks and downlinks in the form of band pairs. As a consequence, each band supported by a phone comprises of two different frequency ranges. The TDD variation depends upon a single frequency range inside a band. This band is divided into pieces in order to assist both the reception and transmission of signals within its single frequency range.
Wimax is an older technology which relies upon underlying wireless (wi-fi) networks. In contrast, within the UK, LTE is founded upon the same type of technology that is presently used by the country's 3G network. For this reason, the UK plans to utilise the 4G LTE technology instead of Wimax.
To comprehend what is LTE may help people make wise purchasing choices. Selecting new devices that support 4G networks are educated decisions. This technology is anticipated to command worldwide telecommunications for years to come.
