Home What we do Critical Communications

NSW Government Radio Network

The Australian state of New South Wales (NSW) has one of the world’s largest public safety radio networks, covering about 266,000 km2. More than 40 emergency services agencies, including ambulance, police, and fire and rescue forces, as well as transport, energy and environment service providers, rely on the network, using around 44,000 terminals to stay in touch.

Keeping the Government Radio Network (GRN) accessible at all times is a big task, one that the NSW Telco Authority (responsible for the overall coordination of radio telecommunication services for the NSW Government) has entrusted to BAI Communications.

Network Operations Control Centre

The Network Operations Control Centre is the hub of the GRN, where BAI Communications controls and monitors the network, activates individual services, locates faults and restores services. Support for users is available through a helpdesk operating 24 hours a day, seven days a week. The network currently involves BAI in managing 194 sites which handle on average some 35,000 voice calls and over 100,000 data calls daily.


In Hong Kong, we work closely with the government on diverse communications projects – including the design and upgrade of the police TETRA radio system, installing communications equipment in critical tunnels and designing and building radio systems for Hong Kong’s central government complex.
