The worldwide approval status for 900 MHz and 2.4 GHz spread spectrum radio products

The use of spread spectrum radios utilizing the ISM bands (902-928 MHz, 2.400-2.4835 GHz and 5725-5850 GHz) is increasing dramatically. All sorts of ITE equipment and now even telecom equipment are using these reliable, high throughput radios. The rules governing these devices have been developing quite rapidly too. Most countries in Europe are going towards a single certification process in addition to the CE certification. The rules are being relaxed in the US as well, but there are always exemptions. This paper gives an overview of the regulations and technical requirements in different countries.
