UMTS LTE instead: At the frequencies, set, go
The UMTS successor is right at the start to halt the LTE data-tsunami stop and finally bring broadband in rural areas. On 12 April will be auctioned the desired frequencies.
The fact that LTE could begin this year in Europe, the USA and some Asian countries, hold Arne Schälicke, Marketing Manager at Nokia Siemens Networks, for "absolutely realistic. He bases his assessment with the fact that several hundred million people currently use third generation mobile networks inspiron e1505 battery, ie UMTS and HSPA. For industry, this high number of participants creates a commercial incentive to upgrade to LTE.
Another reason is the LTE push through quickly, the expert looks at the data explosion, driven by smartphones, "By 2015 we expect an increase in mobile data traffic by 23 ExabytesEin exabyte is one billion gigabytes .." For this data hungry Lord of are the mobile operators focus on LTE. This will initially bandwidths of up to 150 Mbit / s can be achieved with the download. Users could then also look at high-resolution video streams on their smart phone or videoconference.
As a possible spectrum for LTE could be the so-called digital dividend is used. These are the frequencies that are the digitization of television has become vacant. On 12 April auction, the Federal Network Agency just this capacity. So far, the four major mobile operator T-Mobile, Vodafone, O2 and E-Plus advertised and the Stuttgart-based company Airdata to such licenses. The sixth candidate is so far unknown.
UMTS LTE is to offer other than the possible range of other key advantages: "There by about a third more efficient than UMTS thinkpad sl400 battery," explains Schälicke. That is, with the same number of masts that more users can be achieved.
This would not even have a completely new infrastructure be built, "the first manufacturer we supply since September of 2008 base stations via a software update LTE can be made compatible. Especially, these stations "still used for traditional cellular network, said Schälicke.
This and the high data rate, which makes LTE are particularly interesting for the broadband service in rural areas. Therefore requires the procurement procedures of the Federal Network Agency, the potential licensees and to use these frequencies for wireless broadband in rural areas. According to LTE should establish first in cities and towns with up to 5,000 inhabitants.
Problem case Germany
If experts assume that LTE in Germany at the end of 2010 or even before 2011 may be imported, other European countries are much further: In Scandinavia, in December last year launched the first commercial LTE networks. In Oslo and Stockholm, customers can now surf the mobile phone company Teliasonera already faster with USB adapters from Samsung, and Huawei mobile.
Although it is not so far in Germany, is the planned introduction of LTE, critics called on the plan. Sun experts fear the ZVEI Electrical and electronics industry for example, is that the television disturbed by the new mobile standard.
Evidence also provided an examination of the IRT Institute of Rundfunktechnikund ANGAVerband the German cable operators. The workshop showed that although not the cable network is affected, but the cable set-top boxes by the end consumer-LTE terminals can be disturbed when they send on the same frequency inspiron 1501 battery. The same goes for DVB-T boxes, said Jochen Mezger from IRT.
is "Our point of criticism that the Federal Network Agency’s strategy <We solve the problem on the Strecke> pursued," says Mezger. There is however already possible solutions, but these failed so far at the point of funding or are not specific enough.
