One of the most revolutionary smart booster in the world

Introducing the 4th generation Smart Cellular Coverage Solution

for small businesses and residential areas.

  • 100 dB max signal gain covering an area of 16,000 ft² / 1,500 m² per unit
  • Quick and easy setup and installation
  • Boosts both 3G and 4G signal coverage for MTN, Vodacom, Telkom, Cell C, Virgin, Rain and all other networks across Africa under the Network of your choice
  • Easily switch between boosting Vodacom, MTN, Cell C or Telkom signal using the WAVE App


CelFi Pro Installation


Cel-Fi PRO improves 3G, 4G, and LTE cellular service by eliminating dead zones and dropped calls. With 100 dB of gain, the PRO will not only improve cellular service across four (4) concurrent bands, it will also reduce your cell phone’s power requirements and extend its battery life. Cel-Fi PRO covers up to 13,000 ft2 (1,200 m2) of indoor space per system. The system features an LCD color interface, is fully self-contained and self-configuring, and requires no external antennas or wiring. Simply plug it in to boost indoor cellular coverage.

Cel-Fi PRO is ICASA approved. It has been approved by numerous mobile operators and regulatory bodies globally.

Cel-Fi PRO EXA variants feature an external antenna connector. An external Donor antenna can therefore acquire an outside signal, allowing it to be used in applications where no indoor signal is present (i.e. cement, metal walls, etc.). This enables cellular coverage in hard to reach places by allowing the Network Unit to be placed where no service exists. This opens up new opportunities for using Cel-Fi PRO when other solutions fail.

Move the CU further away from the NU to maximize coverage.

The total coverage area equals twice the distance between the NU and the CU. The maximum distance is up to 100 dB path loss.

  • Licence exempt and fully meets
  • Quick and easy setup and installation
  • 100 dB max signal gain covering an area 16,000 ft2 / 1,500 m2 per unit
  • Available for all South Africa Networks
  • Can easily switch between mobile networks via the Cel-Fi WAVE app
  • Boosts both 3G and 4G signal coverage simultaneously
  • Smart Signal Booster with IntelliBoost© Chipset – Unconditionally Network Safe
  • Remote monitoring and management with the Cel-Fi WAVE app

The system needs to detect a minimum signal outside of the building to operate.

Quick Installation: The Cel-Fi Pro comes with a Cel-Fi Whip Antenna and Cel-Fi Patch Antenna. These can be used to get a system up and running in minutes.
Advanced Installation: If you need a more powerful donor antenna you can connect the Cel-Fi Pro to an outdoor Wideband Directional Antenna. If you need to get coverage to more areas of your building, you can use Splitters and connect to multiple Server Antennas


Simultaneously supports multiple channels with bandwidths from 5 to 20 MHz

Total system relay bandwidth of 60 MHz

Relays three (3) channels simultaneously (up to 20 MHz each)

Peaceful coexistence with adjacent Wi-Fi (2.4 GHz & 5 GHz), femtocells, and mobile devices

Automatic Gain Control (AGC) based on fast real-time echo-cancellation

Dynamic gain control always ensures maximum gain, best coverage in ever changing RF environments, without user intervention
