Mobile informatization
Mobile communication has wide covering, locating, long-time online etc. advantages.
With designs of terminals becoming rich and M2M development, mobile terminals can
also gather and process samples of temperature, humidity, human medical treatment,
environment monitoring and other information. Besides, the growing number of terminals
is already a source of innovation to mobile communication industry.

Proof of Concept
(2008.12-2009.8)
• 1~2 sites per vendor Field Trial on Technology Characteristics Verification.
Technology Test (2009.8 -2010.8)
• Indoor and Outdoor( 5~7 sites per vendors) on pre-commercial product functions and performance (Single System Test, IODT/IOT)
Large Scale Filed Trial (2010. 9- )
•Multiple Cities large scale (each above 100 sites) on commercial product functions and performance.
