Register a radiocommunications device under a spectrum licence

You must register any transmitter you will use under a spectrum licence, unless it is exempt. 

Devices you need to register

You must register these if you will use them under your spectrum licence:

  • transmitters
  • groups of transmitters

You must register transmitters because it helps us manage interference. 

Devices you do not need to register

You do not need to register:

  • transmitters that your spectrum licence specifies are exempt from registration. This can differ from band-to-band. It typically includes mobile devices, small cells and other low power devices
  • receivers

While not required, you may wish to register receivers, this may help with managing interference.

How to register your device

You should register devices when you design your radiocommunications system, in case we don't allow them.

If we do allow them, we will give you a certificate. This is called an interference impact certificate (IIC).

Rules for IICs are set out in the Radiocommunications (section 145(3) Certificates) Determination 2012.

We will also add a record to the Register of Radiocommunications Licences.

To register a device you can:

You shouldn't register a device if you don't plan to use it.

For more information read Registration of radiocommunications devices under spectrum licences.

If we don't allow your device

We may not allow your radiocommunications device if it:

  • breaks the main conditions of your licence
  • is located outside of your boundary
  • does not meet the restrictions for how you can set up a device


  • it could cause interference outside your boundary
  • you don’t have permission from affected licensees to accept potential interference

There are a number of ways to calculate your boundary and the expected interference.

Change details on the register

You must tell us if you:
