The Mobile Booster Technology behind Cel-Fi and Cel-Fi Go:

All Cel-Fi and Cel-Fi Go kits come with 3 components to provide voice and data signal boost on mobile networks. We sell full kits or separate parts: 

  • A Donor Antenna: this can be an indoor or outdoor antenna depending on the application, and is used to capture the signal from the main carrier network (Telstra, Optus or Vodafone). This will be either a 3G or 4G signal;
  • A Repeater or Booster: this is the main component, it captures the signal from the donor antenna and boosts it up to 100dB (building models) to a service antenna;
  • A Service Antenna: this will re-transmit the now strong signal at full capacity (five bars). As you distance your mobile phone from the service antenna, the signal strength may diminish. Large buildings may require more than one service antenna to promote full coverage of indoor and outdoor areas.

You can operate Cel-Fi and Cel-Fi Go easily via the Cel-Fi WAVE APP on your smartphone.
