  • For areas with poor outdoor coverage, this model has an external antenna connector to allow the connection of a larger antenna

  • Once set up, the unit will rebroadcast signal throughout the building allowing nearby mobile phones to automatically receive stronger signal - no pairing, no fiddling about


This is a complete 3G + 4G repeater system kit


  • The moderate gain 11-12dBi antenna is ideal for most semi-rural, hilly, and urban areas, and is connected to the repeater via 10m of super low loss LMR400 cable and an SMA patch lead for connecting to the repeater

  • The super low loss LMR400 cable helps compensate for the lower antenna gain by ensuring maximum signal transfer

  • We also provide similar kits for suburban and metro areas with poor coverage indoors despite good signal outdoors, and kits with an upgraded 16dBi (2.3m length) antenna for remote outback areas.

Maximum coverage and network friendly


  • Many mobile service providers do not support the use of personal repeaters on their network, this is due to incorrect set-up or the interference they can cause when connected to the network

  • The Cel-Fi system is the only personal repeater that is widely approved by carriers around the world

  • The Smart Repeater system is very different to a standard repeater, as it is designed to provide maximum coverage, be network friendly and can be easily installed by the end user.


How does it work?


The Cel-Fi system:

  • continuously monitors power levels of the cell tower it is connected to, constantly adjusting its output power to suit

  • amplifies and disburses a particular carrier’s mobile signal, operating within a set frequency band - this means the service provider can shut down the repeater remotely if needed by using a signal from the base station

  • does not interfere with the carrier’s network or other users on the network

  • has a unique installation process to eliminate feedback into the mobile network.


Optus Requirements - Mobile Smart Repeater


  • This is an actively boosted radio transmitter and is subject to regulatory requirements

  • Each unit is registered and locked to a particular country, network, and operation frequency.
