An In-Depth Look at Nextivity Cel-Fi 4G/5G GO Booster Kits

From work-from-home video calls and EFTPOS terminals to simply staying connected with family, we depend on our devices. Yet, we all know the frustration of the "one-bar" blues, especially in large homes, dense office buildings, or regional areas.

Dropped calls, spinning load wheels, and "Message Send Failure" notifications are more than just annoying; they're a barrier to productivity and safety. This is where Nextivity's Cel-Fi GO booster kits come in.

What is a Cel-Fi GO Booster?

Unlike a cheap, illegal repeater you might find on a third-party marketplace, a Cel-Fi GO is a carrier-grade, 100% legal, and ACMA-approved smart signal booster.

Here’s the simple version of how it works:

  • An External Antenna (often a high-gain LPDA antenna) is placed on your roof, where it can capture the strongest available signal from the nearest mobile tower.
  • This signal is sent via a cable to the Cel-Fi GO Repeater Unit, a powerful smart box that "cleans up" and amplifies the signal by up to 100 dB (which is 1000x stronger than a simple passive antenna).
  • The boosted signal is then sent to one or more Internal Antennas (like ceiling domes or sleek wall panels) which re-broadcast the strong, clear 4G and 5G signal throughout your building.

The result? You go from one bar of unusable signal to five bars of crystal-clear calls and fast data speeds.

Understanding Single vs Multi-Carrier Kits

The key to choosing the right kit is understanding your needs. The main difference comes down to boosting one carrier at a time versus boosting all of them simultaneously.

1. The "Carrier-Switching" Solution: Cel-Fi GO G41

This is the most popular and flexible solution for most homes and small-to-medium businesses. A single Cel-Fi GO G41 repeater can be set to boost one carrier at a time (Telstra, Optus, or Vodafone). You simply select your preferred carrier using the Nextivity WAVE app.

This is perfect if everyone in your home or office is on the same network (e.g., everyone uses Telstra).

We carry G41 kits tailored for different building layouts:

  • G41 Pulse Ultrathin 2-Antenna Pack: Ideal for a standard home or small office. This kit includes the powerful G41 repeater, a wideband LPDA external antenna, and two discreet, ultra-thin internal antennas to provide coverage across different rooms or a small floor.

  • G41 Pulse Ultrathin 4-Antenna Pack: Need to cover a larger, multi-storey house or a complex office layout? This kit upgrades to a high-performance Blackhawk LPDA antenna and provides four internal antennas, allowing you to flood a significant area with a strong signal.

2. The "All-in-One" Multi-Carrier Solution: G51 & G32 Install Kits

What if your business has staff on Telstra, clients on Optus, and contractors on Vodafone? Or what if your family members are all on different plans? You need a solution that boosts everyone, all at once.

This is where multi-carrier install kits come in. These are professional-grade bundles that use multiple, dedicated repeaters—one for each carrier—running in parallel.

  • 4G Multi-Carrier Kit (G41 + G32s): This pack includes three repeaters (a G41 for Telstra, and two G32s for Optus and Vodafone), three external LPDA antennas, and three internal ceiling dome antennas. It’s a comprehensive solution for total 4G coverage (with 5G NSA) for all three major networks.

  • 4G/5G Multi-Carrier Kit (G51 + G32s): This is the flagship solution. It features the cutting-edge Cel-Fi G51 for Telstra, which specifically boosts 5G (including the n78 3600MHz band) alongside 3G/4G. Paired with G32 units for Optus and Vodafone, this kit ensures the best possible 4G and 5G performance for everyone, simultaneously, over a massive area (up to 3000 m2).

Which Cel-Fi Kit is Right for You?

  • For Homes & Most Small Businesses: A Cel-Fi GO G41 Kit is the perfect, flexible choice. Just pick the 2-antenna or 4-antenna pack based on your building's size.

  • For Commercial Buildings, Large Enterprises, or Households with Multiple Carriers: A Multi-Carrier Install Kit is the ultimate investment, providing a dedicated, simultaneous boost for Telstra, Optus, and Vodafone.

Stop walking to the window to send a text. Stop apologising for "bad reception" on calls. It's time to take control of your mobile signal.
