Product Description

Customize your ProWay Cel-Fi C2 multi-carrier cell signal booster system

Features of the ProWay Cel-Fi GO C4 four-carrier system

  • Powered by Cel-Fi GO technology, with an industry-leading 100 dB of gain—the highest gain of any carrier-preapproved cell signal amplifier.
  • Carrier-based solution: Choose the four carrier networks you want amplified in your building. (More info on carrier choices.)
  • Your choice of one to four inside antennas for one or multiple zones of indoor coverage.
  • Improves coverage in offices up to 100,000 square feet with four antennas and strong outside signal.
  • Carrier-approved and ready to install; no contracts or licenses required.
  • Completely automatic: Each amplifier selects the tower with the best signal.
  • Unconditionally network safe: Will not interfere with WiFi or other wireless transmissions.
  • Amplifiers housed in a commercial-grade, wall-mounted metal box (24″ × 18″ × 4″) for clean and easy installation.

The ProWay Cel-Fi GO C4 system is a four-carrier Cel-Fi solution that provides up to 100 dB of signal gain for each network. With the C4, you can have the strongest carrier-preapproved cellular booster available with coverage for your choice of four networks—no licensing or carrier contracts needed.

With strong outside signal (−95 dBm RSRP or greater), the Proway Cel-Fi GO C4 can provide up to 25,000 square feet of indoor cellular coverage per antenna. With four antennas and strong outside signal, the C4 can cover up to 100,000 square feet indoors. With weak outside signal (−115 dBm RSRP), a one-antenna C4 system can cover up to 11,000 square feet.

Cel-Fi GO technology is fully automatic and does not require any adjustment. At power-up, each amplifier analyzes its assigned carrier network to determine signal strength and quality, then it selects the best cellular band for that carrier.

Who is the ProWay Cel-Fi GO C4 for?

  • Those who have heavy cellular user and data loads.
  • Those who need improved signal just for specific carriers.
  • Rectangular, L-shaped, long, and tall buildings.
  • Warehouses, manufacturing plants, office buildings, parking structures, government facilities, retail locations, or any other large building.
  • Large custom homes and small offices in areas where cell service is poor
  • Buildings in urban locations with building materials that block outside cell signal (steel, glass, concrete, plaster, etc.).
  • Large areas below ground level, and other places where inside cell reception is poor.

Get more features with the Cel-Fi WAVE app

The Cel-Fi WAVE app for smartphones and desktop computers allows you to interact with your Cel-Fi GO X Smart Signal Booster and access advanced and supplementary features, including:

  • Dashboard: An overview of the state of your Cel-Fi booster systems, including the signal strength, network operators (carriers), and frequency bands in use and the type of coverage (4G/3G).
  • Settings: Change the default network operator for each signal booster, name each booster, and more.
  • Advanced Mode: Get real-time technical overview for troubleshooting devices.
  • Booster Updates: Keep your Cel-Fi booster up to date as new software versions are released.

Download the Cel-Fi WAVE app from the iOS App Store, Google Play, or the Cel-Fi website.

Optional plenum air coax cable upgrade

The ProWay Cel-Fi GO C4 includes 400-type coax cable to connect the amplifiers to the inside antenna(s). If your building requires fire-rated cable in plenum spaces, please ask us about upgrading to ½-inch plenum air coax. Plenum cable fully meets state and federal building codes.

Plenum cable also has nearly half the signal loss per foot of cable compared to 400-type coax cable, delivering stronger signal from the Cel-Fi amplifier to your phones and other cellular devices.

(Plenum air cable is available at additional cost. Call Powerful Signal at 866-912-3444 for details.)

How the ProWay Cel-Fi GO C4 works

Using Nextivity’s IntelliBoost signal processing, the Cel-Fi GO X amplifiers receive outside cell signal from four carrier networks, amplify it, and rebroadcast it inside your building through one or more antennas. This allows you to stay connected when your building’s construction materials block signals from the local cell tower or when outside cell signal is poor.

Works with your choice of four major cellular carriers

The ProWay Cel-Fi GO C4 works with six cellular networks. From that list you may choose any combination of four carriers that you want to support in your building.

  • Verizon 5G/4G (bands 2, 4, 5, 13)
  • AT&T 5G/4G/3G (bands 2, 4, 5, 12)
  • T-Mobile 5G/4G/3G (bands 2, 4, 12)
  • Sprint 5G/4G/3G (band 2)
  • U.S. Cellular 5G/4G/3G (bands 2, 5, 12)
  • GCI Alaska 5G/4G/3G (bands 2, 4, 12)

The four individual Cel-Fi GO X amplifiers are each assigned to an individual carrier. Each amplifier analyzes the qualify of its carrier’s signal and chooses the two highest-quality channels available.

How much area will the ProWay Cel-Fi GO C4 cover?

This system includes flat dome antennas that each broadcast improved cellular signal in a sphere. The radius of that sphere depends on many factors, including:

  • Outside cell signal strength received by the donor antenna.
  • The number of antennas you select for your system.
  • Inside building materials. (Cellular frequencies pass through wood framing and drywall more easily than through steel and concrete.)
  • Cellular frequencies used by the carrier. (Lower-frequency SMH and CLR signals travel farther than higher-frequency AWS and PCS signals.)

In general, the stronger the outside cell signal, the greater the interior broadcast distance.

Under optimal conditions, you can expect the following coverage areas, based on outside signal strength and number of antennas:

 Outside signal strength
1 indoor antenna
2 indoor antennas
3 indoor antennas
4 indoor antennas
Outside signal strength −95 dBm RSRP (5 bars)
1 indoor antenna: 30,000 ft²
2 indoor antennas: 50,000 ft²
3 indoor antennas: 75,000 ft²
4 indoor antennas: 100,000 ft²
Outside signal strength −105 dBm RSRP (3 bars)
1 indoor antenna17,000 ft²
2 indoor antennas: 35,000 ft²
3 indoor antennas: 50,000 ft²
4 indoor antennas: 70,000 ft²
Outside signal strength −115 dBm RSRP (1 bar)
1 indoor antenna10,000 ft²
2 indoor antennas: 18,000 ft²
3 indoor antennas: 23,000 ft²
4 indoor antennas: 30,000 ft²
