But, we are facing what we do not suppose…


LTE Deployment Plan in 2012

3 frequency bands are available

800 MHz band

1.5 GHz band

2.0 GHz band

High quality LTE

Down link: 75MHz (max.)

Rapid implementation

Actual population coverage is aiming at

96% on March 2013


Planned launch of LTE in 2012, but…

au WiFi: The public WiFi for data offloading

WiFi is a LAN technology, so several artifices must

be implemented for WiFi offloading as AP in WAN.

Battery life

Turing of beacon receiving: x2 longer

Ease of setting / switching from cellar

Purpose-built application / Smart Switching (3G <-> WiFi)

Public access point

Nation wide >100,000 APs (2012 March)

~50% of APs are connected by WiMAX

Summary

KDDI's 3M strategy

Multi-device, -network and –use are providing

various choices for customer

Data explosion in mobile networks

Caused by smartphones and other data communication devices

Is a dead-certain phenomena

Data offloading and multi-access networks

WiFi Artifices are needed for better use

WiMAX Methodologies for faster and wider solutions for offloading
