Interoperability PSN LMR
Mike Hunua made this Official Information request to New Zealand Police
This request has an unknown status. We're waiting for Mike Hunua to read a recent response and update the status.
From: Mike Hunua
Dear New Zealand Police,
How will the logistics of PSN LMR work between agencies? Will response agencies talk on each other's channels, or will there be dedicated liaison channels, and how will they be assigned in a major incident, given historically emergency services have had their own communications plans for only their own agencies and in such situations as the Mosque attack in Christchurch, that communications were confused and frantic as per the Royal Commission be prevented on the new system?
How will PSN fit with CIMS?
Will NGCC mandate the use of plain voice on PSN LMR, given that the prowords and radio voice code structure used by Police, Fire and Ambulance are all very different? How will NGCC ensure confusion will not occur when interagency communications are in use?
Will PSN LMR still allow interoperability with the likes of forestry companies, Civil defence, industrial and airports fire brigades, with FENZ, recognised community patrols with police and PRIME units with Ambulance?
Yours faithfully,
Mike Hunua
From: Ministerial Services
