Japan KDDI chooses LTE for its mobile network

This is not yet official, but there is agreement that the Japanese operator KDDI, which operates CDMA2000 networks, will switch in the camp WCDMA / LTE for its next mobile network, like its competitors NTT DoCoMo and Softbank Mobile
If they needed further proof of the excitement generated by technology LTE (Long Term Evolution), which must be followed to networks HSPA (High Speed Packet Access) currently deployed, it should be provided by the Japanese operator KDDI.
According to Kyodo News, the operator, which operates a mobile network broadband CDMA2000 for 3G, is expected to turn to the WCDMA standard competitor, and its evolution LTE, for its next generation network.
While the natural evolution of CDMA2000 tends rather to the standard UMB (Ultra Mobile Broadband) put forward by the American founder Qualcomm, KDDI could also be seen as Verizon Wireless in the United States and benefit from the migration of networks to very high flow to operate a toggle in the choice of technologies.
LTE is already established itself as the main standard broadband
It will be even easier than Motorola has announced a system to ensure a transparent transition (hand-off) of a CDMA EV-DO Rev. A (the equivalent of HSPA) LTE, and conversely, ensuring a smooth transition from one technology to another.
In tilting in the camp LTE, KDDI match its competitors NTT DoCoMo and Softbank Mobile, which will provide a mobile network very high speed using the same standard for the three main operators in the country, facilitating migration one to the other for subscribers.
This is favoured by the Ministry of Internal Affairs and Communications, which wants to ease restrictions imposed by the mobile operators more subscribers to change their mobile when they migrate to a new operator.
Japan will be one of the first, if not the first, to operate mobile networks LTE (known as Super 3G) by 2010, which should provide data rates of 100 Mbps descendants and amounts to 50 Mbps . NTT DoCoMo has recently announced that it had reached speeds of 250 Mbps descendants, a rate that could be applied to networks LTE later, pending the 4G.
