Evolution of NTT high-capacity land mobile communication system
K. Watanabe, Kuniyasu IMAMURA · 2003
The development of a land mobile communication system, MCS-L2 which is Japan's second-generation analog cellular system is presented. The system operates in the 800-MHz band, and service commenced in May 1988 by overlaying it on the first-generation system, MCS-L1, sharing the 15-MHz*2 frequency resources. The field trial results are described. Techniques for increasing the frequency spectrum utilization such as radio zone sectorisation, flexible channel assignment and radio channel interleaving further intended to be applied to MCS-L2 are also discussed. Techniques established by MCS-L2 are basic techniques for digital mobile radio systems.>
