Comfortable communication by combining WiMAX, LTE, 3G etc, and "multi-network" promoted by KDDI?

NTT DoCoMo, Softbank Mobile, eMobile are looking for the full-scale introduction of LTE (Long Term Evolution) at the end of the current third generation mobile phone (3G), but while looking at LTE like other companies, WiMAX KDDI is also showing its own movements, such as focusing on.

An overview of "multi-network" promoted by the company was displayed at the Wireless Japan 2011 venue.

Details are as below.
Wireless Japan 2011A multi-network corner located at the KDDI booth.

Prototypes of terminals compatible with both LTE and CDMA 2000 networks scheduled to be introduced in 2012 by KDDI were on display.

Supports three communication methods: LTE, CDMA 1x, EV-DO

Demonstration of LTE.

"L" indicates LTE, "1X" indicates CDMA2000 1x, "E" indicates EV-DO, and it is currently in LTE communication.

The content of the demonstration is like this.

Downstream 70 Mbps, Upstream 23 Mbps performance was realized.

With multi-network such as LTE, WiMAX, optical fiber, 3G, Wi-Fi, CATV, multi-use of content and service becomes possible with various multi-device ... That's why.

When asked about the future use of the network from the staff of KDDI, LTE has high affinity with current 3G, seamlessly realize communication with 3G and LTE switched, basically, 3G, although the data communication part is used in the form of LTE ... ..., WiMAX has the advantage of high speed and large capacity and the cost of network cost can be finished, so if you select the optimum network according to the application doing.
