The Cel-Fi GO G32 is a highly effective repeater designed to improve Optus mobile voice, text, and data coverage. This model has been designed to improve both Optus 3G and 4G services in a matter of minutes.

Setting up the repeater to improve indoor mobile coverage is simple. The unit has an input connection and an output connection which are set up as follows:

  • Input connection: connected to roof mounted antenna by cable
  • Output connection: can either connect directly to an antenna, or can use one or more cables to distribute signal elsewhere.

The Cel-Fi GO G32 works by decoding and amplifying weak Optus signal detected by the roof mounted antenna. This signal is then boosted up to 100 dB using a linear amplifier and output through the antenna or series of antennas connected to the output port.

Unique to the GO G32, the repeater is IP66 ingress protection rated and built tough for use in outdoor and tough environments.

The Optus Cel-Fi GO G32  can operate on two frequency bands simultaneously, providing either 3G and 4G coverage, or 2C 4G LTE-Advanced for higher data speeds.
