All radio transmitters need to be licensed, regardless of power. For kids toys the ACMA will usually issue a class license that will cover all transmitters of a frequency under a certain power.Tyranus wrote:I'm not sure how this fits in with ACMA, they may not be concerned about anything under a certain power rating.
For example, the 433Mhz band is actually licensed under a number of class and apparatus licenses. What the ACMA calls the primary license holder is actually the military. They have final say over how the band is used and are guaranteed interference protection from everybody else.
The next tier down is the secondary allocation, which amateurs know as the 70cm band.
Underneath this still is a open class license. The ACMA allows any transmitter to operate on this band so long as it meets the requirements of the class license. In this case, it's a limitation in transmitter power.
So kids walkie talkies, wireless LAN and CB radios etc all have to operate with a license and most of these use a class license. With class licensing, individual users don't require their own license to operate, but the radio is still licensed by the ACMA under the appropriate class license.
