摘要： A Cellular network system wherein the physical layer as defined in 802.16a includes means for its optimization for mobile operators for improved reliability, coverage, capacity, user location, fully scalability, and mobility from 2-6 Ghz, while working in a reuse of 1. The same RF frequency is allocated to all sectors in the cell. The system further includes means for its operation in a Coordinated Synchronous mode, wherein permutations, collisions and averaging interferences from other cells cause limitations on the use of high QAM modulations, which sometimes can increase capacity up to three times (64 QAM instead QPSK).
