ISM band

Industrial, Scientific, and Medical band. ISM bands are defined by the ITU-R in 5.138, 5.150, and 5.280 of the Radio Regulations. For the United States, the 902-928 MHz band is an unlicensed frequency band governed by FCC, Part 15. For the European Union, Dubai, and other locations, 865–880 MHz is used, and in Europe and some countries outside of Europe, ETSI is responsible for ISM band regulation.
