y hopping, dual band as well as Nokia GSM system specific features. GPRS and EDGE planning are key challenges for many operators. Radio Planner sup- ports packet-switched radio network capacity planning. With Radio Planner, you can cal- culate the needed GPRS and EDGE capacities in the network based on the selected quality of service criteria and data rates. Coverage can be calculated with the four included propagation models: Okumura-Hata, a Nokia version of Okumura-Hata, Walfisch-Ikegami, and Microcell. There is also an open interface to external propagation models, which means that you can utilise your own prop- agation models if needed. All of these models can be tuned with drive test measurements. Radio Planner also provides coverage planning and analysis support for dual-band networks (shown in Figure A.2). Capacity calculation is based on real network traffic imported from Nokia NetAct (Network Management System). You can distribute this real network traffic data on user- definable clutter or vector weights, enabling accurate capacity calculation, which is espe- cially important in dual-band and GPRS/EDGE planning. The frequency allocation tool minimises interference efficiently by optimising the sepa- ration cost and interference table cost. Allocation accuracy is based on allocation time. The progress of allocation can be followed with statistical or graphical views. The frequency allocation tool supports both RF and base-band frequency hopping. Information management is becoming increasingly important in radio network planning, especially in projects such as microcell planning, where the major part of planning activities can be carried out in the field.
