FCC Radio Regulations

It's not specifically not allowing these devices, it's broadcasting on a restricted frequency without the proper license. The FCC regulates who can broadcast on which frequencies. Getting a ham license can open it up a bit, but there are still regulations to follow.

Not at these frequencies. It's prohibited by the FCC. See some explanations from an insider above.

Using wrong spectrum and jamming communications of others can be illegal without forcing proprietary firmware. It's like making all cars illegal, because someone blocks access roads for a fire brigade.

Pretty sure OP was talking about using the 2.4Ghz/5Ghz unlicensed spectrum. Obviously allowing user transmissions on licensed bands is a bad idea.

From the github repo readme:> In most countries, transmitting radio waves without a state-issued licence specific to the transmission modalities (frequency, power, bandwidth, etc.) is illegal.

This might well violate FCC rules. It's equivalent to jamming a communications channel.

Would probably break the FCC 'will not interfere and will accept interference' thing for unlicensed devices.

what stops the users from broadcasting on that band anyway?

The use-case doesn't really matter; it's against the regulations for that radio band to interfere with other people's usage. Even if you think they're attempting to commit fraud.

If it interferes with radio transmissions, an fcc (or equivalent for your country) complaint is in order?
