November 4, 2014 Development of Leaky Coaxial Cable (LCX) for MIMO


Development of Leaky Coaxial Cable (LCX) for MIMO



Fujikura Ltd. (Yoichi Nagahama, President and CEO) announces that it has developed Leaky Coaxial Cable (LCX) suitable for implementing 2×2 MIMO (Multiple Input Multiple Output).  It has been working on research on 2X2MIMO system, which uses a LCX that also serves as two antennas, in cooperation with Advanced Telecommunications Research Institute International (Yasuo Hirata, President) and Nara Institute of Science and Technology (Naotake Ogasawara, President). 


The data traffic through wireless communication such as cell phones or wireless LANs has been increasing. Consequently, shortages of radio resources caused by many users in places like stations or meeting rooms results in the lower data rate and poor connection.  Two LCXs are considered to be needed to double the transmission capacity of an LCX. The research, however, has theoretically enabled an LCX to have twice the transmission capacity. It is expected to be applied for responding to the increasing volume of transmission. 


The research was conducted under Strategic Information and Communications R&D Promotion Programme (SCOPE 135007001) by the Ministry of International Affairs and Communications.
