The 4 G, born dead mobile network?

The LTE, Long Term Evolution, new fourth generation mobile network, could have problems of fragmentation, making it less attractive.

In a study of the development of the LTE group Wireless Intelligence, carried out in the world, we will have 38 different bands for LTE, fourth generation of mobile network support. The fragmentation of this new technology can pose several problems ultimately.

Fragmentation of the LTE frequencies between 2011 and 2015

First concerned, operators who will have to accept to be elbow to elbow on the frequency bands, they are historically acquired or recently purchased. "Conflicts" may occur, primarily on the 700 MHz band. Is cited the case in the United States, of Verizon who will take the band 746 to 787 MHz while its competitor will operate the 704-746 MHz band, which could make more difficult the transition from a network to another. A small scale, is fully manageable by the operators, but the support of 38 frequencies is more problematic.

Second problem: roaming abroad. Indeed, if the phone supports only the operator its 4 G network, it will be difficult to support all the frequencies of all the countries of the world with the LTE with this mobile phone. Even if this can be corrected at the level of software in the antenna relay for the standardization of frequencies, what chips for mobile phones which are limited on the number of frequencies supported?

Finally, a recurrent information returns: the LTE frequencies would disrupt the GPS signals, even those of the TNT, which is not without many problems currently. Because it is still expected that more than 200 LTE networks in more than 70 countries are deployed by 2015. Hope that a global regulation could be affixed to all this, without which the future of 4 G might darken...
