Interference to remote-operated devices

The ACMA is the correct body to report issues of interference. However the ACMA does not investigate interference in all instances.

A large number of short range radio transmitters share the frequency spectrum and operate under the Radiocommunications (Low Interference Potential Devices) Class Licence 2000. More details about this class licence are available here.

These devices operate on an uncoordinated basis—they share the spectrum with other devices. The potential for interference between devices has been managed by placing limits on the operating parameters of devices (such as the type of device, radiated power levels, and areas and frequencies of operation).

Although low impact potential devices can be used for radio applications with commercial or safety-of-life implications, users of such applications are encouraged to pay particular regard to the suitability of operating under this class licence for their radiocommunications needs.

If interference occurs, the onus is on the user of a device to take measures to resolve that interference, for example by retuning or ceasing to operate the device. Some devices have the capacity to be retuned in order to assist the user in avoiding local interference.

If you believe that there is an interference problem, you might start looking for other devices which may be in your close proximity. Such things may include:

  • wireless doorbells
  • wireless fan systems
  • wireless headphones
  • garage door openers
  • car remote controls
  • interior WiFi systems
  • LED down lights etc.

If you have isolated all other wireless devices under your control and the problems still persist, it may be necessary to speak with your neighbours to identify if they have wireless devices that operate on the same frequency. The problem may be from another device using the same frequency located near to your house.

The suggested approach is to first switch off the power to your house. If this resolves the problem then the device is something inside your property. If this does not resolve the issue then you will need to engage the assistance from your neighbours. This will involve them switching off their power and if the problem goes away then the problem at least has been isolated. Should they not want to turn off the power at least ask them if they have any of these devices listed above and check to see if they are working properly. A faulty contact in a wireless door bell can cause your problem.

Should you still have problems in resolving this matter then you may wish to contact providing your full address contact telephone number and name. The ACMA may be able to provide some further advice or, if in the area, provide onsite diagnostic capability. The response time cannot be guaranteed.
