UMTS radio network planning

The new Universal Mobile Telecommunications System (UMTS) is a 3rd
generation cellular system for mobile telecommunication. It is more
powerful, more flexible, and more radio spectrum efficient than its
predecessors. Unlike 2nd gneration systems like GSM and GPRS, radio
transmissions are not separated but instead superimposed in time or
frequency, separable only by means of their encoding, therfore called
code devision multiple access or CDMA, in short. For this to
work, a minimum ratio between radio transmission signal strength as
perceived by the receiver and the interference must be achieved. In
consequence, UMTS radio cell capacity and coverage are strongly
inversely coupled through system self-interference.

In this talk, we present the governing interference constraints for
UMTS radio network planning and introduce a mixed integer programming
model for UMTS radio network design. The scope of this model is to
configure base stations, heights, azimuths, and tilts as well as the
cell's dominance areas.
