Abstract :
Significant statistical trunking gains can be achieved by dynamically sharing a number of channels between adjacent cells to take advantage of their noncoincident busy hours and the nonuniformity of their distribution of users. However, because channels are now shared between adjacent cells, frequency reuse distances are violated. The use of switched-beam smart antennas and other techniques helps to mitigate the co- and adjacent channel interference into surrounding reuse sectors so that call drop rate can be maintained or even improved while the call blocking rate is reduced, equivalently achieving a gain in capacity. This solution offers a simple and effective way of squeezing more capacity, and thus revenue, from an otherwise capacity-limited network
