Federal law prohibits the marketing, sale, or use of a transmitter (e.g., a jammer) designed to block, jam, or interfere with wireless communications. See Communications Act of 1934, as amended, 47 U.S.C. §§ 301, 302a(b), 333.
Section 301 of the Communications Act: No person shall use or operate any apparatus for the transmission of energy or communications or signals by radio
except under and in accordance with [the Communications] Act and with a license in that behalf granted under the provisions of this Act. 47 U.S.C. § 301.
Section 302(b) of the Communications Act: No person shall manufacture, import, sell, offer for sale, or ship devices or home electronic equipment and systems, or use devices, which fail to comply with regulations promulgated pursuant to this
section. 47 U.S.C. § 302a(b).
Section 333 of the Communications Act: No person shall willfully or maliciously interfere with or cause interference to any radio communications of any station licensed or authorized by or under [the Communications] Act or operated by the
United States Government. 47 U.S.C. § 333.
Jammers cannot be marketed or operated in the United States except in the very limited context of authorized, official use by the federal government.

United States Federal Communications Commission issued its largest fine ever - $34.9 million against a Chinese company that makes and sells signal jammers.

Indeed, the FCC is asking that Humphreys pay $48,000 for unauthorized operation of a jammer, use of an illegal device and causing intentional interference.
Hopefully you aren't connected to these companies as this would constitute advertising, which also violates federal law.
