It limits power, emissions, identification, and repeater behaviour to prevent harmful interference and protect critical channels (notably UHF 476.525 MHz).\n\nIt affects radio network operators, emergency services, businesses and equipment manufacturers by enforcing spectrum-efficient use, reliability limits, and safeguards for public safety communications."}},"importantCases":[],"_links":{"self":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025","history":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025/history","analysis":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025/analysis","conflicts":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025/conflicts","importantCases":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025/important-cases","documents":"/api/acts/radiocommunications-licence-conditions-land-mobile-licence-determination-2025/documents"}}
