Re: A small proposal
Geolocation of a mobile in 3D is very tricky as all the signals the mobile is measuring are effectively at ground level. Even if you had pure line of sight and excellent timing resolution or perfect power control, the differences in signal measured needed between heights would be tiny, and the standards don't allow that - measurements are basically a short int for signal power and/or quality for each cell reported.
Our you could mandate phones use GPS to work it out and report to the base station. Also bad, as it won't work indoors.
None of the above stops the mast from radiating a bit into the air, anyway. You'll not be able to stop that (and most masts are already directional) as the signal just bounces off everything.
The solutions are either to widen the guard band, mandate a better cutoff on used frequencies (for all devices concerned), make better altimeters or keep everything suitably far apart to avoid the issue (assuming tests show there is interference).
