Radio Network Tuning and Optimization UMTS
•For network tuning, we need to relay on field measurements which require extensive drive tests
•Finding the best possible configuration for antenna heights, tilts, azimuths and parameter setting for
all the present cells/sectors in the network and also for any new sites that might be needed to improve
coverage
•Power adjustment can also be used for network tuning but can become complicated and result in poor
network performance
•Use of Remote Electrical Tilt (RET) Antenna is preferred over mechanical tilt antenna
•Neighbour definition is of prime importance in UMTS network (Soft handover gain and interference
reduction). Keep neighbour list upto 20.
•Automated tools are needed that could suggest the best possible neighbour relations, antenna heights and
tilts by using both the field measurements and the propagation models & simulations
•Skilled people, right methods and advanced tools are needed to perform
3G tuning and optimisation
