Binary CDMA which originated in Korea is the technology for the short range radio transmission, it has both advantages of CDMA and TDMA, and it enables the video transmission and multimedia transmission.
The wireless access technology which is released or developed by now contains some problems such as radio interferences and etc. In order to solve these problems, Binary CDMA is the unique technology, has the both CDMA's advantage and TDMA's advantage and it is the solution that has been developed in Korea.

SMEC is focusing to the development of solutions with use of video modem and data modem on the base of B-CDMA technology and is finding new market in security area, IoT area, AMR area and etc. in domestic and global.
