@David-TP have emailed to tech support. 0-30mhz as a start, floor rises on spec an (at distance) by 20 odd Db. Measured on a viavi spec an. Eg when floor raises broadcast reception is effected along with HF radio equipment. If looking from the equipment antenna perspective it's upwards of 45Db. Keeping in mind this is with the device reset or as a AP, thus VDSL frequencies (and stand to be corrected) should have no Tx for upstream.
In terms of the radio equipment - S1-3 floor changes to s9 floor - unusable within HF bands as a start.
The deco is located approx 20 meters away from equipment and 40-50 meters away from antenna. Keeping in mind the impact so far is on appropriate class license equipment, this is obviously a problem.
Cheers
