Maximise your mobile coverage


We are working with our Griffith mobile carriers (Optus and Telstra) to improve mobile signal coverage, but we need your help!

Do you encounter network coverage black spots where you experience call dropouts, low signal strength  (only 1 or 2 bars on your handset) or no signal at all?

The Network and Communications team can help!  Just complete the mobile coverage request  and we will relay this information to our carrier.

Did you know that by performing some basic troubleshooting checks on your device that you can improve your mobile coverage?

1. Update your carrier settings

Occasionally you will receive notifications on your device to install new carrier setting updates.  These updates can affect network, calling, cellular data, messaging, personal hotspots and voicemail settings, so make sure your device software and carrier settings are up to date.

For other devices, please refer to your manual.

2. Refresh your network connections.

If you have travelled out of network range then back onto the network, you may need to refresh your connection. To do this, power off your mobile device and then turn it back on again.

3. Check if your location is causing signal interference

The device or its signal reception may not work properly if you are in the following surroundings:

  • Inside a building or underground car park
  • Driving through a tunnel (such as Clem 7) or mountain range
  • Under a tin roof
  • In a forest or bushland
  • During a storm or heavy rainfall

If signal coverage is an issue inside a building on a Griffith campus, let us know (] as we may be able to install a repeater.  A repeater receives a signal and retransmits it at a higher level giving you better mobile coverage in buildings!
