Abstract :
The basic cellular architecture for maximizing independent mobile multiple accesses was conceived over 50 years ago. The cellular architecture is revisited as it is now applied to the CDMA air interface and in view of changes in the paradigm of the service from coverage-limited mobile traffic to a mix of urban pedestrian and in-building usage and from voice-only to a mix of data services. The salient features of CDMA, different from those of narrowband communications, provide opportunities for enhancement and optimization of the service by modifying the air access topology and control. These are reviewed, along with relevant experience.
