Tools for (E)GPRS Planning

NetAct Planner

5 © 2006 Nokia 13-467422 v.1.0

Tools for (E)GPRS Planning

• NetAct MultiRadio Planner• Data service area and throughput analysis

• Coverage analysis for both GMSK and 8-PSK modulations • The service area analyses are based on the interference levels in the network

and on the selected coding scheme• C/I is calculated as an average interference in the network• Data rate/TSL depends on the interference ratio and it is shown in each pixel• Link Adaptation and Incremental Redundancy included• Frequency Hopping utilization• User-editable C/I vs. throughput dependency table

• User editable Coding Schemes• GPRS (4), EDGE (9)
