Radio network optimization is core to network operations today. TEMS Investigation captures the RF parameters in downlink and reports them in the customized format. These reports are used for optimizing the networks. In addition to traditional RF data, L2/L3 messages, and IP information collection and together with support for a wide range of services, makes TEMS Investigation the ideal choice for network operators.

Designing a network isn't easy. You have to conside terrain, clutter and anything else that may block RF signals and inhibit coverage. The purpose of RF planning is to maximizing coverage, increasing capacity and minimizing capital expenditure throughout the life of a network. The tools helps in Radio propagation analysis, network. The tools helps in Radio propagation analysis, Automated frequency allocation, Capacity and coverage, Interference mitigation, Throughput and grade of service analysis, Analysis of networks running multiple technologies.
