Cel-Fi GO X: The Best Booster for Buildings With Weak Outdoor Signal

Waveform's 90-Day Money-Back Guarantee + Unlimited, Fanatical Technical Support

The Cel-Fi GO X is Single Carrier: That means it boosts signal for one carrier at a time. You can easily switch carriers using the WAVE app, but if you wish to boost signal for multiple carriers in your building, you may need a multi-carrier booster or multiple GO X systems.

Cel-Fi GO 5G DSS Support: The Cel-Fi GO X supports 5G DSS (Dynamic Spectrum Sharing) on bands 2, 4, 5, 12, and 13. These bands are primarily used for 5G by AT&T and Verizon. T-Mobile runs their 5G services on bands 41 and 71. Unfortunately the FCC has not yet updated rules to permit boosting of these bands. As a result, no booster sold to consumers in the US can legally amplify T-Mobile 5G signal.

The Intelliboost Chipset

It's What's Inside That Counts

Building a custom signal boosting ASIC allows breakthrough advances, but takes years of development and millions of dollars. Cel-Fi are the first and only company to have made that investment.

Unlike traditional "broadband" boosters made by other manufacturers, the GO X actively demodulates and digitally filters celllular signals.

Demodulation and narrowband filtering solve many of the problems that plague traditional devices and allow for much greater signal amplification.

How It Works

Sending the Right Signals

The GO X doesn't simply amplify the signal from outdoors and rebroadcast it inside the building.

With the power of the embedded IntelliBoost chipset, it also:

  • Filters the signal
  • Measures advanced signal metrics
  • Scans to determine the best bands to amplify
  • Controls uplink power to ensure network safety
  • Performs echo-cancellation to improve isolation
  • Adjusts amplification parameters for best performance

The result? The greatest coverage area and fastest data speeds possible with any consumer signal booster.

1. Which Outdoor Antenna Should I Purchase?

Choose the outdoor antenna type below

2. How Many Indoor Antennas Do I Need?

The GO X's coverage area depends on whether the space you're installing in is subdivided with walls.

We also recommend using at least one antenna per floor.

Frequently Asked Questions

Does the Cel-Fi GO X support 5G?

Yes and no.

The Cel-Fi GO X supports 5G "dynamic spectrum sharing," which is primarily used by AT&T and Verizon.

If you are AT&T or Verizon user and your phone shows 5G or 5GE (but not 5G+, 5GUW, or 5GUC), the GO X is 90% likely boost your signal.

The GO X does not support any 5G services for T-Mobile (see below for explanation).

More specifically, the GO X's supported bands are Band 2, 4, 5, 12, and 13. As a result, Verizon's 5G DSS on Band 2 & 5 and AT&T's 5G DSS on Band 5 are supported by the Cel-Fi GO X.

Unfortunately, FCC regulations prevent any consumer-grade signal booster from amplifying T-Mobile's two primary 5G bands: n71 and n41.

Will the Cel-Fi GO X improve my data speeds?

Very likely yes!

As long as you take the time to aim your outdoor antenna properly, you are likely to see much faster data rates once the GO X is installed.

Note: If you're using a Home Internet Gateway or cellular modem and want the absolute fastest data rates, you will see faster data rates using the right MIMO antenna kit.

Will the Cel-Fi GO X work outside the United States?

No.

The Cel-Fi GO X amplifiers we sell are configured to only work with US cell carriers. While the same bands are used abroad, the GO X amplifier is pre-programmed to work with a subset of carriers only. Try looking for a local reseller for a unit that will work in your country.

Note: If you are looking for a Cel-fi solution for use outside the US, we would recommend that you reach out to Cel-Fi's list of approved distributors to see what products are available for your region.

How much cell service do I need outdoors for the Cel-Fi GO X to work?

Even though the Cel-Fi GO X is much stronger than traditional wide-band cell booster, it's critical that you have at least 1 bar of usable signal outside or on the roof of the building you're installing the GO X in. If you don't have 1 bar, or if you're not sure, please give us a call or contact us for assistance via our Contact page.

Now, what do we mean by usable? Well, you need to be able to place a call and use data reliably when outside. When running a speed test, you should have decent upload and download speeds. Cell boosters can bring signals inside from outdoors, but if the signal outside your building isn't usable, the Cel-Fi GO X isn't going to help.

There are also other better measurements that can be used to determine whether your local cell service is usable by the Cel-Fi GO X. More specifically, the following cell signal measurements found in our "Field Test Mode for iPhones and Android" need to be within these ranges:

  • Signal Strengths (dBm RSRP) need to be better than -115 dBm (i.e. closer to zero)

  • Signal Qualities (dB SINR) need to be better better than 0 dB (i.e. more positive)

If you don't see these measurements on your phone or have any questions regarding the Field Test, please give us a call or contact us for assistance via our Contact page.

Can I use Cel-Fi GO X with a Cellular Router, Modem, or Gateway?

The GO X will definitely boost signals for a cellular router or modem, however:

  1. This version of the Cel-Fi GO X has a single outdoor antenna (SISO). We also sell a MIMO version of the Cel-Fi GO X as well that will offer an even greater increase in data rates.

  2. You might want to consider using MIMO antennas in place of a booster. MIMO antennas support a wider set of bands than the Cel-Fi GO X because, unfortunately, FCC regulations limit the number of frequency bands that can be amplified by consumer signal boosters.

Why should I buy the single-carrier Cel-Fi GO X over multi-carrier boosters offered by Wilson, SureCall, etc?

The Cel-Fi GO X has a number of features that are unlike any other consumer-grade cell phone signal booster. Specifically:

  1. The GO X has up to 100 dB gain and isn't not restricted to the maximum 70 dB gain like most multi-carrier boosters by the FCC.

    • This means that the Cel-Fi GO X can cover the same area with 1000x weaker signal than a multi-carrier booster, or can cover up to a 20x larger area.
  2. The GO X can be easily optimized and monitored by the Cel-Fi WAVE application for iOS and Android devices.

    • The WAVE app allows you to connect to the device over bluetooth, change settings such as carrier and band, and see detailed diagnostic information such as incoming signal strength (RSRP) and signal quality (SINR).
  3. NEMA 4 is weather-resistant and can be installed outdoors.
