ABSTRACT:
A telecommunications system and method is disclosed for providing adaptive channel allocation for indoor cellular systems, which utilizes interference measurements on both the down-link channels and the up-link channels. This can be accomplished by using a Stand Alone Dual Channel Scanner (SADCS) to assist indoor cellular systems in allocating traffic channels on the basis of interference from external systems, which measures both the up-link and the down-link at the same time. A number of SADCSs can be placed at strategically located points in the building to measure interference on a channel by channel basis, and to communicate the results to the indoor base station, which can then allocate traffic channels with high confidence of maintaining a good speech quality.
