Lte Mobile

The mobile Internet booms. Particularly the paragraph of Smartphones rises strongly, whereby also mobile data services become ever more popular. One thinks e.g. of the many “Apps” (briefly for mobile applications) with the I-Phone and other Smartphones, whose number already exceeded the 200000. This development leads to a proper explosion of the data traffic in the mobile communications networks, which cannot be mastered with portable radio standards of the third generation (3G) like UMTS (universal mobile Telecommunications system) in the long run no more. Here LTE comes into the play. LTE stands for “Long term Evolution” and already the portable radio standard of the fourth generation (4G) one calls. 

LTE uses the frequency spectrum substantially more efficiently, saves thus costs of the network users and makes also many higher data rates possible than its predecessor standard UMTS. About 100 MBit/s with the download and 50 MBit/s are intended with the Upload with LTE. It goes however more. One of the LTE pioneers Ericsson already reached data rates of 144 MBit/s with the download, while with UMTS (with its extension HSDPA) in the comparison only up to 7,2 MBit/s can be achieved. But LTE does not only offer higher data rates, but also the response times of the net are substantially smaller. That is called that requesting of data, like e.g. a calling website or calling an email up goes, many faster. LTE combines techniques, which are used e.g. also with the digital terrestrial television, like OFDM (Orthogonal frequency division multiplex) and MIMO (multiple inputs multiple outputs). Thus the frequency spectrum the available can be used very efficiently. 

That is important, since the frequencies of many prospective customers hot contests are. In addition, LTE works in 2,6 the GHz frequency band, can be used within the range of the digital dividend, thus in no longer the frequencies between 790 MHz and 862 MHz, necessary by the digitization of the terrestrial television. LTE was developed as a pure communication procedure. Language services as with its predecessors UMTS and GSM (Global System for mobile Communications) will play no role during the introduction of LTE still. However momentarily specifications are developed, which make a speech transmission possible also over LTE. LTE still is in the starting hole. 

Momentarily there is world-wide only a commercial LTE net in Sweden and Norway von Ericsson and Telia Sonera. This started already 2009. Also the commercially available LTE receivers are still relatively limited and are limited first also only on USB sticks and PC maps. Later it in addition, LTE compatible mobile phones will give. In Germany LTE is not yet available. Still in this country only some compatibility tests and pilot projects take place. There could be at the end of 2010 or at the beginning of of 2011 then in addition, in Germany first LTE offers. The frequencies, in which LTE can be used, are already auctioneered.
