There's no restriction on encryption in the commercial/business bands.

> assuming that you got them tested and licensed

This one is the kicker - it costs about $10-20k to get a device FCC certified, at least for part 90 devices, which is the industry I work in. A license to operate the devices runs around $500 (for ten years).

Interesting, thanks! That's for part 15 devices, which are exclusively devices operated without a licence, generally at low power.

Part 90 is a different beast, operating with licences, and at higher power limits. It doesn't surprise me the equipment licencing requirements are more intense.
