Nominal cell planning can be performed using a pre-defined cell size based on the desired reliability level, cell overlap, subscriber penetration. Cellular Expert allows users to conveniently create frequency reuse plan.

Coverage prediction includes field strength and best server calculations. Cellular Expert supports the following prediction models for 2G/2.5G networks: Line of Sight type models for open area, Hata type models for urban and suburban areas, Walfish-Ikegami type models for city environment and Diffraction model for open areas with solitary obstacles. Walfish – Ikegami and Hata models can be combined with Line of Sight model and include correction factors like diffraction, clutter loss offset or building penetration. Cellular Expert has the ability to tune models by drive test data or implement additional prediction models. Best server prediction functionality includes th first and N best server calculations.

Cellular Expert has the capability to calculate total C/I and C/A interference coverage and coverage of interference for each channel. Channel Query tool allows users to perform a quick check of C/I interference without setting the frequency information. Interference Matrix tool calculates the interference level values between a carrier and the victim sectors.

A powerful set of drive test data processing, querying, prediction accuracy evaluation, reporting and visualization tools enables to analyze drive test data and use it for model calibration. Model tuning functionality allows users to achieve high precision results.

Automated cell planning allows you to calculate optimal number of sites and sectors, sector height, transmitting power, antenna type and orientation for required serving area.

Automated frequency planning tool for 2G/2.5G networks is used to find the minimum number of carriers required to serve defined area within a given interference threshold. The assignment of frequencies are based on metrics calculated from sector or cell traffic demand, number of neighbors, area of neighborhood and other parameters. As a result, new frequency plan, containing non interfering frequency channels for each sector or cell, is created.

The tool provides functionality for automated connection of customers to serving sites according to visibility or signal strength conditions. Optimal number of sites from all candidates is selected according to the signal quality requirements.

Live traffic data provided by network equipment can be imported to Cellular Expert and automatically linked to particular cells. Live traffic data spreading can be calculated using a weighted clutter and the best server rasters.  As a result, the traffic load for each sector/cell/site can be estimated.
