Long Term Evolution, a new (fourth-generation) 4G mobile network, is likely to have fragmentation issues making it less attractive. A study of the development of the log term evolution by the group Wireless Intelligence, conducted around the world, showed we have 38 different frequency bands to support the LTE fourth generation 4G mobile network. The fragmentation of this new technology will ask eventually several problems.
First concern, operators will have to accept to be neck and neck on the frequency bands, whether old or recently purchased. “Conflicts” could arise, especially on the 700 MHz band. The case is cited, the United States, Verizon will take the band 746-787 MHz, while its competitor will operate the band 704-746 MHz, which could hamper the transition from one network to another. On a small scale, it is perfectly manageable by operators, but the support of 38 frequencies is more problematic.Second problem: roaming abroad. Indeed, if the phone only supports its 4G mobile network operator, it will be difficult to support all frequencies in all countries of the world using LTE with mobile phones. While this can be corrected in software in antennas for uniform frequency, what about the chips of mobile phones that are limited on the number of frequencies supported?
Finally, a recurring cost information: the frequencies of the LTE disrupt GPS signals and even those of TNT, which is not without many problems now. Because it is still anticipated that over 200 LTE networks in over 70 countries are to deployed by 2015. Hope that global regulation can be applied to standardize all this, otherwise the future of 4G mobile may be gloomy.
