Incremental capacity gains for high blocking sites using dynamic channel sharing

Significant statistical trunking gains can be achieved by dynamically shari ng a number of channels between adjacent cells to take advantage of their n oncoincident busy hours and the nonuniformity of their distribution of user s. However, because channels are now shared between adjacent cells, frequen cy reuse distances are violated. The use of switched-beam smart antennas an d other techniques helps to mitigate the co- and adjacent channel interfere nce into surrounding reuse sectors so that call drop rate can be maintained or even improved while call blocking rate is reduced, equivalently achievi ng a gain in capacity. This solution offers a simple and effective way of s queezing more capacity, and thus revenue, from an otherwise capacity-limite d network.
