Who Are NSW PSN Technicians?

NSW PSN technicians are field engineers, RF specialists, and infrastructure support personnel employed or contracted by the NSW Telco Authority, the agency responsible for managing the PSN. Their work ensures that emergency services have uninterrupted radio communications across the state.

• Employing Body: NSW Telco Authority

• Primary Role: Maintain and optimize the PSN infrastructure

• Coverage Area: Over 540,000 square km, with expansion targeting 85% of NSW land area

Technical Responsibilities

Technicians handle a wide range of tasks across the PSN’s Project 25 Phase II trunked radio system:

• Site Maintenance: Inspecting and servicing radio towers, antennas, and shelters

• RF Testing: Signal strength validation, coverage mapping, and interference mitigation

• Talk Group Maintenance: Activating and testing technician talk groups (TGIDs 11000–11099)

• Control Channel Setup: Ensuring correct control channel broadcasting for trunked site operation

• Equipment Installation: Deploying base stations, repeaters, and microwave links

• Firmware Updates: Applying software patches to network hardware

• Indoor Coverage Design: Implementing DAS (Distributed Antenna Systems) for buildings

Tools and Technologies

• Radio Standards: APCO-25 Phase II (TDMA)

• Frequency Bands: 403–430 MHz and 450–470 MHz

• Monitoring Tools: Spectrum analysers, signal generators, and network management software

• Vendor Partnerships: Motorola Solutions and other tech providers support infrastructure and software

Technician Talk Groups

Technicians use unencrypted talk groups in the 11000–11099 TGID range for coordination and testing. These channels are often active during site upgrades, fault investigations, or coverage validation.

• Example TGIDs: 11000 (Tech 00), 11001 (Tech 01), etc.

• Usage: Site-specific testing, RF diagnostics, infrastructure coordination

Expertise and Training

Technicians typically have backgrounds in:

• Radio frequency engineering

• Telecommunications infrastructure

• Digital trunked radio systems

• Emergency communications protocols

They may hold certifications in RF safety, P25 systems, and network design, and often collaborate with emergency services during major incidents or network expansions.
