CelEnhancer™

Wireless systems are always implemented with some overlap between cells to allow spectrum reuse. The overlap aids call-handoff from one cell to another. CDMA and TDMA systems may benefit from this overlap through diversity. However, overlapping also increases interference and, consequently, may diminish capacity. This effect is very complex in CDMA systems and also affects TDMA systems. Achieving the proper amount of overlap while simultaneously minimizing interference is a very daunting task. Maintaining coverage while minimizing interference is an important step to significantly increase capacity. CelEnhancer™ automatically shapes cell footprints to simultaneously minimize interference (considering diversity effects), maintain the same coverage, and balance traffic.

Designers can shape cell footprints by adjusting one or more parameters.CelEnhancer™ analyzes all selected parameters on a sector-by-sector basis and chooses the footprint that minimizes the use of system resources.

In CDMA based systems, CelEnhancer™ allows minimization of system resources usage without affecting the quality of the existing system. This is achieved by reducing the hardware required to carry same amount of traffic, by reducing the network overhead for soft handoff without increasing system load, and by reducing the total transmission power required in the downlink. For systems using multiple frequency channels, CelEnhancer™ allows users to optimize cell footprints considering the frequency plan or not. This makes the tool extremely flexible as it offers carriers the opportunity of re-defining physical parameters of sites before or after making changes on the frequency plan.
