 air interface measurements, providing effective support in all analysis tasks including GPRS and EDGE network measurement analysis, for network planning organisations. PC compatibility with laptop computers enables field use and provides planning engineers with real mobility. Quality Planner has a common database with other NetAct Planner modules, thereby enabling seamless data usage between radio planning and optimisation. Drive test measure- ments can be analysed in the same map view as coverage, traffic or interference predictions, enabling a unique and accurate network analysis. Quality Planner also offers efficient prob- lem solving and diagnostic capabilities. The drive test replay functionality of Quality Planner enables a broad range of information to be displayed in the 2D map window during the drive test measurement analysis, including layer 3 messages, serving cell information, radio environment data, serving and neighbour graphs. Quality Planner supports a thorough analysis of radio network performance. The call suc- cess analysis is an important part of the field test measurements. This function summarises the status of each call made within the field trial measurements. Handover analysis pro- vides the ability to analyse cost-effective methods for both inter- and intra-cell handovers. The neighbour analysis performs a checking routine based on the real BSC neighbour lists. Possible missing or not measured neighbours are registered as problems. The signal INTEGRATED NETWORK PLANNING TOOL: NOKIA NETACT PLANNER level analysis clarifies the network field strength levels and the quality analysis co- and adjacent-channel interference levels. Quality Planner's Probe module is a network analysis tool that enables you to bench- mark the quality of your network and easily compare it against your own network's past performance. Whereas the analysis functionality of Quality Planner is designed to pinpoint specific problems and faults in the network so that you can locate and fix them, Probe gives a wider pictu
