mbebs/RFTools ? reverse-engineered prompt

Build me a QGIS plugin for RF and wireless telecom planning that feels like a real engineer’s toolkit. I want a simple menu with tools for drawing and visualizing cell sites and sectors on the map, planning PCI and RSI values with conflict avoidance, optimizing azimuth and electrical tilt, predicting coverage as a heatmap, and checking interference between sectors. It should work with LTE and 5G data, read the needed fields from a layer, and write the results back into the layer or create a new output layer when that makes sense.

Please make the dialogs clean and easy to use, with sensible defaults and clear messages when fields are missing. If you need to look up current QGIS plugin patterns or docs online, do that. Also include the sample data or help text so someone can understand what fields they need without reading code.
