The term 'unlicensed spectrum' is interpreted to include frequency bands in which the FCC allows sharing with licensed services as well as proposals for possible future unlicensed frequency allocations. Any person or entity may use unlicensed spectrum for either private or public purposes so long as the user's equipment is certified by the FCC and operated in conformity with Part 15 of the Commission's rules. In contrast with most licensed spectrum use, unlicensed spectrum users enjoy no regulatory protection against interference from other licensed or unlicensed users in the band.

Both commercial and non-commercial entities use unlicensed spectrum to meet a wide variety of monitoring and communications needs. Suppliers of wireless devices must meet requirements for certification to operate on frequency bands designated for unlicensed use.
Examples of unlicensed use include garage door openers and WiFi communications.
