Developed in Korea, Binary CDMA is a proprietary short-range wireless communication technology that combines the strengths of CDMA and TDMA to enable multimedia transmission, including video. Conventional wireless access technologies for industrial digital devices—whether commercially available or under development—have various issues, including radio interference, depending on the characteristics of each system. Binary CDMA is an innovative solution developed in Korea to overcome such limitations by combining the strengths of CDMA and TDMA. SMEC is developing diverse solutions powered by B-CDMA video and data transmission modems, expanding its presence in domestic and international markets across the security, IoT, and remote meter reading sectors.
B-CDMA is a solution being developed in collaboration with Innovid Co., Ltd.
