When your mission is critical

How comprehensive communications capabilities support public safety.


This is the scene:

Officers are hot on the heels of a speeding driver. He crosses the border into a neighbouring country, where local officers join the chase.

But the pursuit ends in disaster as the reckless driver enters a tunnel and crashes. The confined space and thick smoke make any rescue attempt much more difficult.

Such a complex situation calls for all-round, seamless co-operation between several different agencies and information systems in control rooms. Here's how it would work: 

In the control room …

A call comes in about reckless driving. The dispatcher locates the incident and identifies the nearest available response units using a mapping application. The map also shows which fire engines and ambulances are in the area. 

The dispatcher sends officers to pursue the suspect vehicle, which is heading for the border. The officers' status switches to show they’re on a mission.

In the vehicle …

An officer presses the “start pursuit” button on his touch-screen panel, and away they go. The on-board camera tracks progress and streams video footage back to the control room.

With the suspect vehicle in their sights and visible to the on-board image capture system, the officers run a vehicle check at the touch of a button.

Sure enough, the car is stolen. 

Behind the scenes …

The border is coming up fast, and the officers will need support from the neighbouring force. The Inter-System Interface (ISI) between the neighbouring TETRA networks makes it possible for the command and control and field officers to communicate with their counterparts across the border.Local officers join the pursuit as it crosses the border.

At the crash site …

The suspect is speeding through a tunnel when he loses control of the vehicle and crashes.

Officers open a new traffic incident in a special command and control application, which results in a call for backup from fire fighters and medics. The dispatcher forwards a copy of the tunnel floor plan, together with a photo of the crashed vehicle taken from CCTV footage in the tunnel.

The officers grab their TH9 handheld radios and head into the tunnel on foot. It’s a long tunnel and they lose touch with the radio network. They can still talk to one another in Direct Mode.

Even in this hazardous and confusing situation, the officers are confident that if any of them stops moving for too long, the Lifeguard function on their radio will alert the rest of the team that they may need help.

A fire engine arrives at the tunnel entrance with a TB3p mini base station on board. Once it’s activated, the officers in the tunnel can leave Direct Mode to communicate with the control room via the network again.

Police officers and fire fighters manage to rescue the driver. He seems unhurt, but the paramedics check him over. Officers use a handheld scanner to read the driver’s license and pull up his records so they can be sure whom they’re dealing with.

The officers head back to headquarters as the paramedics rush the driver to the hospital.

This imaginary scenario is an example of how comprehensive communications capabilities can support public safety. Vehicles are on the way of becoming mobile offices where professionals can do their jobs faster, more safely and more efficiently.
