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
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.
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.
