Fixed cell assignment for forward link in broadband wireless networks
Jae Deok Lim, Harold P. Stern · 2005
This paper proposes a new allocation method, called the fixed cell assignment, which provides wireless Internet access by employing time division multiple access transmission for the forward link in broadband (10 Mbit/s) wireless networks. The system is configured with directional base station antennas and omnidirectional mobile antennas, with each cell divided into six sectors, and sectors numbered in the same order for every cell. Access is controlled based on availability and sector number, and half the sectors in each cell reuse the same spectrum with power control mitigating the effects of co-channel interference. Performance is evaluated using both analytic techniques and computer simulation for the maximum capacity tradeoffs.
