Band 28 is a low-frequency LTE band (700 MHz) widely deployed by Australian carriers.

From a radio perspective:

  • Lower frequency → longer range
  • Lower frequency → better penetration through walls and terrain

It forms the coverage layer of LTE networks.

If a tracking device doesn’t support Band 28, it will eventually lose connectivity in Australia – which has enormous regional/rural areas as well as incredibly long and deep tunnels like those under metropolitan Sydney. That’s why Freematics ONE+ now ships with SIM7670G (B28 supported) for reliable Australia deployments.

1) Nationwide coverage backbone

Australian networks use a layered approach:

LayerBandPurpose
CoverageB28 (700 MHz)Wide-area, reliable signal
CapacityB3 (1800 MHz)General traffic
High capacityB7 (2600 MHz)Dense urban speed

Without B28, devices rely on higher bands with shorter range and weaker coverage.

2) Critical after 3G shutdown

With 3G retired in Australia:

  • Legacy low-frequency coverage is gone
  • B28 now fills that role

Devices without B28 lose their fallback coverage layer.

3) Real-world impact

In practice, lack of B28 leads to:

  • Dropouts in suburbs
  • Poor performance in tunnels and indoor parking
  • Weak signal on highways and regional roads

For telematics and IoT:

  • Missing data points
  • Unstable connections
  • Increased reconnections
