That would be the US ISM band.

Since I actually do wireless work I'll make another comment.

There are research and development exemptions to the licensing requirements.
Ergo I can build, test or modify any radio I want for research purposes no license
required.

What I can't do is deploy or sell them.

Even with licensed devices changes to the hardware or firmware are
allowed as long an an engineer believes that the changes will not have
any effect on the radio's meeting the applicable standards.

Also for radios operating on the cellular band there are really two
licenses. One is the regulatory license. The other is the carriers
certification.
