5G Telstra Update: Telstra has completed 5G tests using their repurposed 3G bandwidth frequencies within their network allowing 5G to operate in the low-band 850MHz spectrum. This will no doubt increase 5G Telstra coverage in areas across Australia making the 5G network accessible for more people. 

We have confirmation that the G31 CEL-FI GO mobile signal booster device will eventually get a firmware update which will theoretically allow 5G low-band to be available to consumers without the need to upgrade your existing cellular frequency antenna and/or G31 device. Other mid and high band 5G frequencies will not be available on the G31 for the foreseeable future.

Please note that 5G high-band frequencies are rarely available in remote areas where a CEL-FI GO is commonly used. The 4G network will still be the backbone of cellular data and communication in Australia for the foreseeable future even when the 3G network is eventually switched off by the end of 2024.

  • Low Bands - Under 1GHz (Telstra 850MHz)
  • Mid Bands - 1 GHz to 6 GHz (Telstra 3.5 & 3.6GHz)
  • High Bands - 24 GHz to 40 GHz

Buy with full confidence knowing that the G31 CEL-FI GO will still be relevant for many years to come!
