Whats the frequency Kenneth?
Its more like the 2.4 GHz ISM (industrial, scientific and medical) band that 2.6 GHz. 2.6 GHz is typically being rolled out for small cells in urban areas for capacity.
2.4 GHz is one of the bands your microwave in the kitchen can use to nuke your Marks and Spencer ready meal and is typically on a shared basis. So any user (RPAS included) has to accept interference and deal with it. What the RPAS does with the loss of command and control likely varies between manufacture.
A spot of GPS spoofing (at a technical level) would offer another level of interruption to RPAS in flight. Maybe spoofing the white house geo-fence for starters would be a plan?
