Portable wi-fi to support disaster-hit communities

Satellites and solar panels will hope to keep NSW communities connected as bushfire season approaches.

The state government is rolling out portable technology that will deliver back-up internet connectivity during natural disasters so communities and emergency responders can stay connected.

The technology includes trailer-mounted, solar-powered satellite internet stations that can provide wi-fi coverage to a roughly 500 metre radius.

There are four portable connectivity units on the way that can be combined to cover a larger area.

The units will also be available in Service NSW disaster recovery centres, alongside a satellite-equipped vehicle so the agency can set up temporary offices with internet access.

The supplied connectivity will also be handy for contacting family members, applying for government support and lodging insurance claims after disaster events.

"This technology will help people contact loved ones and stay connected in times of need," Premier Chris Minns said.

Emergency Services Minister Jihad Dib said the technology can be rapidly deployed.

"We already have a reliable radio communications system for first responders, but natural disasters can damage this infrastructure," he said.

The government is investing about $5 million in the new technology, which will be delivered this summer.
