After collecting the necessary information, you should fine tune signalling and radio resource sharing
parameters. Network optimisation is a continuous process during and after the launch of the network.
For example, if it is found that an area within a building has low signal level. There should be an immediate
scrutiny of base station and/or repeater locations, heights and tilts. The problem is sorted out by moving
the relevant devices and altering the tilts of these devices.
For buildings/halls constructed with high signal attenuation materials, deploying additional base stations
will be one of the solutions.
