interference from high-voltage power line

Hi

I visited a small business today that is situated beneath a high-voltage power line

They have rubbish ADSL bandwidth and apparently they can’t benefit from satellite dish access because of the overhead power lines.

I would like to provide them with a higher bandwidth uplink via a point to point RF link (5GHz)
and equip their premises with Wifi access points (interior and exterior)

Is this feasible ? Or should I expect disappointment

thanks

I have only one experience with one user on power line converter from 100.000V to 10.000V terminal.
We provide internet as usual, on 5GHz i see no interferencies.
