Radio Channel Migration from 25kHz to 12.5kHz

On this page you can find out more about the phase-out of 25KHz Analogue Land Mobile Channels in VHF and UHF Bands. 

What do you need to know about migrating from Wide Band to Narrow Band?

In November 2010 the Ministry of Economic Development – Energy and Communications Branch advised that there would be a phase out of 25kHz analogue land mobile radio (LMR) channels.

What is the Deadline for Migrating from Wideband to Narrowband in New Zealand?

The deadline for migrating from 25kHz channels to 12.5kHz channels is 1 November 2015.

What are the Options for Migrating from 25kHz to 12.5kHz?

You should consider your options in tandem with your plans, if any, for migrating from analogue radio to digital radio.

  • Users with an offset channel plan in the E band wanting to migrate to digital prior to 1 November 2015 can migrate to 12.5 kHz channels in the EE band (also in the VHF range) or other bands open for digital LMR licensing.
  •  

  • Users with an offset channel plan in the E band wanting to continue operating analogue service after 1 November 2015 can migrate to 12.5 kHz channels in the EN band (also in the VHF range) or any other band open for narrowband analogue LMR licensing.
  •  

  • Introduction of digital LMR in the EN and ENX bands can be considered on a case by case basis.
