- Link budget and propagation model definition and selection.
- Market level coverage designs including model tuning, coverage maps, cell counts, and CW drive testing.
- Search ring release and coordination with site acquisition and other teams.

For a major equipment manufacturer, we developed and implemented a proof-of-concept business intelligence solution, providing near real time access to key network deployment data and statistics, ultimately paving the way to reduced reporting costs, increased operational effectiveness, and accelerated network deployment. Highlights of our solution included:

- Integration of multiple data sources covering hundreds of data types (activity, schedule, equipment, resources, etc.) and near unlimited number of data points for a national LTE deployment.
- Development of interactive dashboards with browsable access to data and statistics, including historical and trending analysis.
- Drill-down access to low level data (e.g. cluster and site).
- Simplification and reduction of reporting requirements via access to historical and current data.
- Intuitive forecasting via user-manipulated click-to-view data analysis.
