As annoying as this might sound, this is one of the

Relying on a TCN would yield very inconsistent results.

Couple of comments:
Regarding ISM spectrum sharing: the 2.4 GHZ band (2400-2500 MHz) and the
5.8 GHz (5725-5875 MHz) are certainly shared with ISM devices- microwave
ovens, induction heaters, etc. However, the 5.2 and 5.4 GHz unlicensed
bands (UNII) are not shared with ISM devices. However, th

For managing Canopy elements, Motorola Prizm is probably the way to go.
