Attorney, Agent or FirmInternational ClassesH04Q 007/20H04Q 007/36 AbstractA telecommunications system and method for a frequency re-use plan is disclosed which reduces the adjacent channel interference between cells, while maintaining good co-channel interference in a four cell frequency reuse plan with a center-excited three sector directional pattern. This can be accomplished by structuring the four cell frequency reuse plan such that no adjacent cells use adjacent channels. As a result, the adjacent channel interference can be minimized, the radio coverage can be extended and in-building penetration can be improved. | |
