Product Description

Cel-Fi GO X is the only in-building cell phone signal booster brand and model that offers the highest 100 dB Gain allowed by FCC while operating on a single Carrier network at any time. However, this Cel-Fi GO+ X smart signal booster is switchable easily thru an app to work on any service provider including Verizon Wireless, AT&T Wireless, Sprint, US Cellular or T-Mobile.*

If your Carrier is not listed here, your service provider must be a MVNO. In that case, simply contact your service provider to ask which major carrier network they use in your area. Then set that one in the Cel-Fi Wave app to boost its signal.

CelFi Go X is ingenius cellular amplifier or repeater kit that boosts mobile reception over up to 15,000 sq. ft. inside any home, office, and building by up to 100dB Max Gain. Using the Cel-Fi Wave App, the boosted service provider network can easily be switched to the most desirable one based on circumstances. Therefore, this 100 dB Gain high power Sprint, AT&T, Verizon, T-Mobile signal booster can be used on any cellular network for best cell signal amplification - better than any other carrier-agnostic cell phone booster kit.

CelFi GOX signal booster does not require broadband home Internet service for it to work. It is a signal booster system that uses Nextivity's Cel-Fi Smart Signal Booster technology to increase data and voice coverage significantly using already existing signals outside building or house. It takes off-air donor signal from the Macro network and relays it into the building.

As it is not a simultaneous multi-carrier device, the FCC does not restrict its gain to 70 dB. Cel-Fi GO X Stationary signal booster is NEMA 4 rated weather resistant and does not interfere with other wireless devices. This multi-carrier solution (requires switch using a Smartphone App to use single carrier at a time) is ideal for use in commercial properties, government buildings, agricultural settings, small manufacturing operations, rural areas, businesses, and large homes. It provides additional 30 dB gain compared to all-carrier models making it ideal for buildings where outdoor coverage is weak (-80 dBm RSRP or less than 3 bars).

It is ideal for boosting 3G, 4G, LTE signals within urban residential and business structures like small buildings, apartment complexes, and skyscrapers with extremely poor or no signals inside. It is also ideal for housings in rural and remote places such as cottages and cabins with weak signals outside and inside.

Note: If no coverage outside (no service, no signal bars), a cell phone signal booster is not likely to help. A Distributed Antenna System (DAS), Small Cell Technology, Femtocell signal enhancing system or Picocell signal transmission system will be required in those instances when there's no cell phone service outside. In such circumstances, submit request for signal enhancing service by our professional enhancement system designers and installers.

Cel-Fi GO-X with +100dB gain for T-Mobile, Verizon, Sprint, US Cellular and AT&T.*

Easy-to-deploy, cost efficient, and boasting an additional 30-40 dB on similar signal boosters, the Cel-Fi GO-X from SignalBooster.com is the only 100 dB cell signal booster for Verizon, AT&T, and T-Mobile. This additional gain means improved cell signal strength, much faster data speeds, and a lot wider coverage area. It greatly enhances 3G, 4G, and LTE cell service for wireless devices in your home, office, or other building with up to 15,000 ft. indoor space. And there's better monitoring with the Cel-Fi Wave App for android and iOS devices, which makes installation and monitoring easy. With the Cel-Fi Wave App, users can connect to the device via Bluetooth to optimize and monitor the Cel-Fi GO-X and view diagnostic data, signal strength, signal quality, and gain.

The introduction of the Cel-Fi GO-X means no more frustration; being forced to put up with undelivered text messages, slow data rates, and dropped calls due to weak signal. Cell signal is amplified by the Cel-Fi GO-X cell signal booster for T-Mobile, AT&T, Sprint, U.S. Cellular or Verizon, only one carrier at a time - to deliver reliable and improved cell signal coverage. And, with the Cel-Fi GO-X there's no need for a wired internet connection, unlike the Verizon LTE Network Extender and the AT&T MicroCell.

Everything you require for installation comes complete in the booster kit when you purchase a Cel-Fi GO-X cell phone signal amplifier from SignalBooster.com, and this includes extras like an antenna mount and a lightning surge protector, both of which will assist in getting your booster fully operational. The installation manual for the Cel-Fi GO-X cell phone signal booster is thorough and easy-to-understand, and in no time at all you will be enjoying the benefits of your new cell signal amplifier.

About the Cel-Fi GO-X Home and Office Indoor Signal Booster Kit.

With the CelFi GOX signal booster kit, cellular reception can be boosted in buildings of up to 15,000 ft.². The booster with two panel antennas allows for signal to be boosted in open-space buildings of up to 15,000 ft., or up to 3,000 ft. in up to two floors in an office or typical home situation. This powerful technology can dramatically improve data and voice coverage in up to 2 bands for LTE, 3G, and 4G. This signal booster kit has been designed specifically to improve both indoor cellular coverage when only one external signal bar is available.

The Cel-Fi GO-X is very cost-effective and easy for an installer to employ. And, with the Cel-Fi WAVE platform, this innovative signal booster is easily monitored and optimized; and it is simple to switch carriers. There is no need to be connected to Wi-Fi, and there are no monthly fees. Because the Cel-Fi GO-X is not a multicarrier broadband device, it is not restricted by the FCC to 70 dB gain, so this powerful device provides a gain of a whopping 100 dBs.

Important: Outdoor Signal Strength Required.

It is important to note that this kit does not require Internet access and does not use your Internet Service Provider (ISP) bandwidth. However, in order for the Cel-Fi GO-X cell phone signal booster from SignalBooster.com to work effectively, you must be able to access at least 1 or 2 bars of reliable outdoor signal. The Cel-Fi GO-X cell phone signal booster works by amplifying and bringing the signal indoors, resulting in the same signal strength indoors as outdoors. For areas that suffer from extremely poor outdoor signal, the new high gain Cel-Fi LPDA Antenna is available for purchase, separately.

Which parts do the respective in-building signal booster kits include?

Per Nextivity, Inc., the manufacturer of Cel-Fi, only original Cel-Fi antennas must be used. Therefore, SignalBooster.com offers authentic Cel-Fi exterior and interior antennas bundled with our kits as follows:

1st Option: Indoor Ceiling-Mounted Dome Antenna Kit.

This Cel-Fi GO-X cell signal booster from SignalBooster.com for Verizon, AT&T, Sprint, US Cellular and T-Mobile comes complete with a dome antenna, which is a ceiling mounted antenna that transmits signals in all directions. For this reason, the dome antenna should be installed as close as possible to the center of the coverage area. Because dome antennas do not support multilevel coverage, they should be installed throughout a building to ensure adequate coverage.

It is important to note that a dome antenna can only be used if the antenna can be mounted to the ceiling and you have access to the back side of the ceiling in order to run the cable and install the antenna. You will be able to do this if you have a loft or crawl-space above the ceiling or if the building has ceiling tiles. (If you don't have access to the back of the ceiling, we strongly recommend that you use a panel antenna). The powerful Cell-Fi Go-X cell phone signal booster is capable of covering up to 1,500 ft. on a single floor or up to 10,000 ft. in open space.

Everything you need for safe, easy, and complete installation is included in the Cel-Fi GO-X kit including exterior Yagi & interior Dome antennas, two (2) lengths of 30-foot ultra-low-loss cable, two (2) SMA to N-type adapters, lightning surge protector, grounding kit, and exterior antenna mounting pole.

Outdoor Directional Antenna + Mounting Pole.

All stated above Cel-Fi GO-X options from SignalBooster.com include a Cel-Fi Directional Outdoor Antenna and Mounting Pole. Pointing the directional outdoor antenna in the direction of the nearest tower will improve the signal quality and the signal strength.

Cel-Fi WAVE App.

By downloading the Cel-Fi WAVE App you can monitor and control your GO-X with your android or iOS device, giving you complete control over the signal booster. Besides viewing detailed diagnostic data, you can choose the bands to be amplified by the device and the carrier you wish to boost. You will, of course, need Internet access to be able to download the WAVE app.

Features of the Cel Fi WAVE App:

  • Using the Cel-Fi WAVE app you get to choose the carrier to be amplified by your Cel-Fi GO-X signal booster; meaning you can switch between Verizon Wireless, T-Mobile, and AT&T Wireless.
  • You can help determine the ideal external antenna location by running an "Antenna Position Test".
  • You can clearly see how much the signal is being amplified by the Cel-Fi GO-X.
  • You will be able to see which bands the Cel-Fi GO-X has located signal on.
  • At any time you can view the diagnostic data relating to the performance of your Cel-Fi GO-X.
  • For troubleshooting help from our customer support team you can send a log of the performance of your signal booster.

Please note: Internet connectivity will be required on your phone during setup for AT&T because AT&T requires the registration of GO-X devices prior to operation.

*Carrier Compatibility:

The Cel-Fi GO-X cell signal booster is compatible with:

  • Verizon 4G, LTE (Data & VoLTE).
  • AT&T 3G, 4G, LTE.
  • T-Mobile 3G, 4G, LTE.
  • Sprint 4G, LTE Band 2 (Only Data)

The Cel-Fi GO-X cell signal booster is NOT compatible with:

  • Sprint 2G, 3G (Only Voice).
  • Verizon 2G, 3G (Voice).

Once again summarizing as stated above: The Cel-Fi GO-X cell signal booster does not support Verizon and Sprint 2G/ 3G service.

Important Note For Verizon & Sprint Users:

Please note that the Cel-Fi GO-X cannot amplify the older 2G and 3G services; however, it does amplify Sprint LTE & Verizon LTE signal if you have a usable and reliable outdoor signal. It is important to note, though, that unlike Sprint, the majority of devices released by Verizon over the past few years use Voice over LTE (VoLTE), which means that the 2G/ 3G network is not used and calls are already using the LTE network which will be boosted.

Important Note For Sprint Users:

Cel-Fi GO-X cell signal booster supports only 4G LTE Sprint network for data communications.

Important Note For T-Mobile and AT&T Users:

Providing you have usable and reliable 3G, 4G, or LTE outside signal, you should experience no problems at all using the Cel-Fi GO-X signal booster.

Testing Your Outdoor Signal.

With the Cel-Fi GO-X it is critical that you have one or two bars of usable, reliable outdoor cellular signal to be brought indoors and amplified. So, before you purchase the Cel-Fi GO-X cellular signal booster you should have your external signal tested. If you can achieve 1 to 2 bars of usable, reliable external cellular signal then that signal can be amplified by the Cel-Fi GO-X and brought indoors. It is highly unlikely that you will be able to achieve more bars indoors than you have outside. It is important to remember that signal bars are not just strength - they also show the quality of the signal. When you boost signal it increases the strength, but the quality is not increased.

With additional accessories and the downloadable Cel-Fi WAVE, this smart NEMA 4-Certified signal booster can also be used in a stationary vehicle such as a parked RV. The tough design of the Cel-Fi GO-X means this booster can handle outdoor installation because it is weather resistant against water, dirt, and dust.

How to Know Which Style of Indoor Antenna to Purchase.

  • Dome Antenna: Because a dome antenna spreads the signal equally in all directions it should be installed as close as possible to the center of the area you're trying to cover. Note that you need viable access to the back side of the ceiling surface in order to run the cable if you're going to install a dome antenna. This type of antenna will work if you have a crawl space, loft, or ceiling tiles.
  • Panel Antenna: With a panel antenna, the signal is directed in the direction the antenna is pointing, which means it can be installed on a wall. If you don't have easy access to the back side of your ceiling then a panel antenna can be used.

You can expand the coverage area by using the two interior antenna booster kit, as provided in option 3 and option 4.

Benefits of the Cel Fi Go-X Home and Office Cell Phone Signal Booster.

The coverage area of the Cel-Fi signal amplifier kit depends on the signal strength at the location where the outdoor antenna is positioned and the number of indoor antennas it is paired with.

Outdoor Signal Estimated coverage area
Strong (5 bars) up to 15,000 square feet
Medium signal (3-4 bars) up to 10,000 square feet
Weak signal (1-2 bars) up to 5,000 square feet

 

How many antennas are required?

In general, the coverage area of a system increases with the number of antennas used. Signal does not pass through walls and air that easily, so adding antennas helps expand the coverage of a signal amplifying kit.

As a general rule, one antenna should be installed for every 750 to 1000 square feet of space in a typical office or home that is split into smaller spaces. For more open environments, including warehouses or open office floors, one antenna is needed for every 1,500 to 2,000 square feet.

Questions & Answers

QUESTIONS & ANSWERS

Ask a Question
  • My company of approximately 70 employees needs a signal booster for Verizon, AT&T and T-Mobile devices that will not require any roof installation. We're looking for devices with simple installations that just need to be attached to a wall somewhere within the building. Would you provide list of links to your devices that fit this description?

    Yes, there's an option that is plug and play as well as does not require outside antenna installation. They are called Cel-Fi PRO & DUO+ kits depending on the Carrier you need for improving network coverage. 

    They consist of two back boxes - one (network unit) to be placed at best signal location on the floor (usually near a window because best signal strength is usually found where there're least building construction materials) so it can catch maximum signal to amplify, and one (coverage unit) to be placed farthest away to provide maximum conical range coverage.   

    Both simply need to be plugged into a power supply and they configure themselves automatically. They do not need Internet connection, either. Therfore no ethernet cables need to be connected to these devices. They are considered over-the-air (OTA) whereby network unit catches signals from outside, over the air...

    However, it is very important to note that these devices are set to program with only a single Carrier. You cannot change the carrier on them like the Cel-Fi GO X kits. Secondly, they require good signal strength indoors atleast at that one spot where you can place network unit. If not, unfortunately, Cel-Fi GO X with exterior antenna installed will be your only option.

    Since these Cel-Fi DUO+ and PRO plug and play kits work only with a single Carrier, you would need to buy three sets of them (one for each service provider - AT&T, Verizon, T-Mobile) as needed.

    Each can cover up to 15,000 sq. ft. indoor space. Therefore, depending of areas to be covered for better cellular coverage, you may need to buy additional sets of those three.

    Please contact is if you have any questions or concerns.

  • Can Cel-Fi GO boost the signal of multiple cellular networks at once?

    Cel-Fi signal boosters are operator specific, and will only boost one operator at a time.

    Being operator specific is one of the main reasons that we are network safe and can provide 100 dB of signal gain, and why we are the only signal booster approved by a growing number of operators.

  • No bars - My unit is not finding the cellular signal.

    If you have no bars, your unit may still be trying to find the cellular network.

    Your unit may display a blinking green power indicator, this can sometimes take more than a few minutes.

    If you have bars of service on your phone at the location of your donor antenna but not at the server antenna, after 60 minutes try a simple restart.

    To restart your unit simply unplug it for few seconds and then plug it back in.

    If the restart does not solve the issue please reach out to your point of sale for support.

  • Why do I have to register my Cel-Fi?

    Why is this being done?  

    Because cellular systems are protected assets of the Operators that own them.  

    Many boosters in the market cause problems for those networks (which means all of us using the networks too).  

    New FCC/Operator approved boosters are better and don't cause problems, and Cel-Fi is the only booster in a special class of boosters that allows 100 dB of signal gain (30 dB or 1000x the gain of all other boosters).

  • How do I register my Cel-Fi system?

    The process is very simple and just takes a minute by following the link below to your Operator’s Registration site.  

    If your system was provided by your Operator it may be preregistered (see product box insert).   In USA:   If your operator is T-Mobile, MetroPCS, TruPhone, or another T-Mobile network operator, please register your booster at: Register T-Mobile Signal Booster
    If your operator is AT&T, Aio, or another AT&T network operator, please register your booster at: Register AT&T Signal Booster

  • No LTE - My phone still does not have LTE.

    There're a few reasons why your phone would experience an issue with the LTE service. You may not have LTE in your area, your Cel-Fi system may have lost the LTE signal due to intermittent network outages, or your phone may not support LTE. Check to see that your phone shows an LTE signal in the location of your donor antenna.

  • I have installed Cel-Fi but I do not see more bars on my phone.

    There could be several reasons for this:   First try toggling airplane mode on your phone near the server antenna, this will allow your handset to have a fresh look at the available channels.

    Also verify that your phone is compatible with the channels that your Cel-Fi system is boosting (maybe your handset is "unlocked" and actually does not fully support all your current operator's channels).

    iPhones can also show fewer "bars" of signal if the network is heavily loaded.

  • My Status Indicator is solid red.

    There're several reasons why your status light would be flashing red. The best way to determine the specific reason for your flashing light is to use the WAVE Mobile application while connected to your device. For more information about Cel-Fi WAVE please visit www.cel-fi.com/wave.

  • My Status Indicator is flashing red.

    There are several reason why your status light would be flashing red. The best way to determine the specific reason for your flashing light is to use the WAVE Mobile application while connected to your device. For more information about Cel-Fi WAVE please visit www.cel-fi.com/wave.

  • My Status Indicator is solid green but my phone still has poor signal at the donor antenna.

    If your Cel-Fi GO has a solid Status Indicator light in either yellow or green, the system is fully functional.   If your system has a solid (non-red) status light but your phone is not picking up a stronger cellular signal you might need to check the server antenna, make sure that your server antenna is fully functional.

    Try swapping out your server antenna with another antenna.

    If the issues persists please reach out to your point of sale for support.

  • My Status Indicator is blinking green but my phone still have poor signal at the donor antenna.

    A blinking green status light indicates that your Cel-Fi GO is still in the startup process. Depending on the complexity of your cellular network, this process can take some time. If the units is still blinking for more than 30 minutes please attempt a restart. This is not something that should continue, but if it occurs frequently please reach out to your point of sale for support.

  • No Power - The unit is not lighting up.

    When your system does not power up, one of the following things could be happening. You could have a power adapter failure, a hardware failure, or the system could need a simple restart. Make sure that you power source is a functional outlet. Test something else, that you know works in the same outlet, or try moving the Cel-Fi GO to another outlet that you have confirmed has working power. Still Not Working? It is possible that you have a bad power supply, or malfunction of your Cel-Fi GO hardware. This is not something that should continue, but if it occurs frequently please reach out to your point of sale for support.

  • Can you use AT&T carrier today and tomorrow change to Verizon and vice versa by changing a setting in the unit or not?

    Yes you can, by opening and setting the respective Carrier in the Cel-Fi Wave app that can be installed in your smartphone. Usually, for efficiency and cost savings, all carriers get together and put their transmitters on the same cell tower so your signal should be great on any carrier you choose. However, in an instance when your new carrier's signal is not boosted strong enough after changing, you may need to tilt exterior antenna to point in different direction to point to new carrier's cell tower and then you would be all set.

  • My house has Verizon and Visible (Verizon MVNO) - will one kit work for both?

    Yes, the Cel-Fi GO X will work with Visible Wireless because it is a MVNO of Verizon Wireless. As long as you have 3G, 4G or LTE service on Visible mobile network, you can set the carrier to "Verizon" in the Cel-Fi Wave App's settings. Boosting Verizon Wireless network will also boost Visible phone signals because it is the same cellular network.

  • Does this signal booster work with Cricket?

    Yes, the Cel-Fi GO X will work with Cricket because it is a MVNO of AT&T. As long as you have 3G, 4G or LTE service on Cricket, you can set the carrier to "AT&T" in the Cel-Fi Wave App's settings. Boosting AT&T Wireless network will also boost Cricket Wireless signals because it is the same cellular network.

  • What is the longest distance I can mount antenna from the cel-fi unit? I live in a valley and considering mounting atop the hill behind my home.

    Technically, you can go as long as you need depending on the strength of the donor antenna signal you can get. The longer your cable run, the more signal loss you will incur but it may be worthwhile if you have no signal at any shorter distance. If you go longer than 100 ft., we would recommend thicker lower loss LMR-600 cable. Even with LMR600 cable, going farther than 200 feet may negate any Gain received, but it truly depends on how strong of a signal you get atop the hill. If strong enough, it may easily offset the signal loss incurred by the extra long cable. Depending on the frequency, attenuation or signal loss ranges from 4 to 7 dB per 100 ft. for LMR400 equiv. cables and 3 to 5 dB per 100 ft. For LMR600 equiv. cables.

  • Can I use this cell phone signal booster in my RV?

    Yes, you can use the single panel antenna version in a stationary RV providing up to 100 dB Gain. For mobile RV version, we carry Cel-Fi Go M kit providing up to 65 dB Gain. It is bundled with RV antenna that can be permanently installed so you need not worry about installing it every time you park and uninstall when leaving. Amazingly, both GO-X and GO-M can be switched back and forth for "mobile" or "stationary" mode via the Cel-Fi app.

  • Can I use the cel-fi go x with multiple phones and tablets at the same time?

    Yes, if they are all on the same mobile network such as AT&T, Verizon or T-Mobile. It works for only one carrier at a time, but any number of cell devices like Androids, iPhones, etc. on that same network will pick up the boosted signal.

  • When switching the carrier to boost via cell phone app called WAVE, do you have to be at the site within range of cellular amplifier, or can it be changed remotely?

    Sorry, you will have to stay within range of the cellular booster main unit to be able to adjust the settings. The reason is that it uses local Bluetooth wireless technology to connect your smartphone to the booster versus using the phone network to connect to the booster. There's no remote access tool as of yet but that can change in very near future because we can see that this feature would help many.

  • How many cell phone users can it extend cellular coverage for? Our church can have 50 to 100 phones at a time depending on the number of people attending.

    There is no set limit of how many users can enjoy the benefits of the booster because it depends on the strength of outside signal. Stronger the signal outside, the more stronger the coverage bandwidth inside. Up to one hundred users should all work fine but bear in mind that it will boost signal for only one carrier you choose with the WAVE app. If you want to cover multiple carriers simultaneously, you will need to buy multiple Cel-Fi GO Xs and set each to boost different carrier network that you need to cover.

  • Will this signal booster work with Straight Talk?

    Yes, but StraightTalk uses different major carriers in different parts of the country. Therefore, you will need to use WAVE app and choose the major carrier that StraightTalk is using in your area. Simply choose one by one and see which one boosts your signal and you will know for sure because signal bars will jump and increase in number:)

  • Will it work to boost AT&T Nighthawk LTE mobile hotspot router (MR1100)?

    Yes, just like cell phones, mobile hotspot router antennas look for signal to catch to improve connectivity. With better signal inside the house, its wireless connectivity will improve like it will improve for smartphones in the house. For best results, place your ATT Nighthawk LTE mobile hotspot router (MR-1100) as close as possible to your interior antenna.

  • Can we use more than 4 antennas? What are advantages and disadvantages?

    There's no limit but usually we recommend up to 4 as kitted in this listing. You can buy additional 50 ohm interior antenna expansion kits if you have more far flung areas that need better signal, but those antennas will reduce coverage of initial 4 antennas gradually depending on outside signal strength. If signal strength is not strong outside to begin with, we do not recommend more antennas. If signal strength outside is very strong, you can easily add more interior antennas to spread the signal more efficiently than it would otherwise spread, trying to go through multiple walls and other obstructions in the house. However, we recommend using combination of splitters and directional couplers or distribution taps to make up for signal loss caused by longer cabling that may be needed, or by sending more signal towards a long line of daisy-chained interior antennas.

  • Using Verizon hotspot for our internet as no cable and have metal roof so service is terrible. What can you recommend?

    We recommend the most powerful Cel-Fi GO X 100 dB gain cellular amplifying system that will help maintain connectivity of your Verizon cellular modem to the nearest Verizon tower, consistently.

  • Hi, I am thinking about purchasing the cel-fi go-x cell booster. It says it is limited to 1 carrier. If someone with another carrier tries to make a call, will their phone simply roam on the carrier it is set on or will they show 0 bars at all? Currently i am running the Wilson ag pro 75 which is a multi carrier but does not run on 700mhz for LTE so I am looking for a better set up but I do not want to be limited to only me using the cell signal and no visitors can ever use there phones unless they are on the same provider as me. I don't want to switch it back and forth an always someone not be able to use there phone. Hopefully your response is positive and I can purchase this booster from you. Thank you

    You seem to have understood correctly. You can set this booster to your Carrier's network through its app in your phone, and you would technically experiance up to +100 dB Gain in your home which will give you great reception for talk and data.

    However, we want to make sure that you understood that your visitors on another Carrier network will not be affected adversely - They will simply continue to receive signal from their Carrier's network as if the booster is not there.

    Secondly, we would like to point out that changing the Carrier is much easier that you seem to think. All it takes is for you to open its app in your smartphone and choose the Carrier you want to boost - and then you can change it back after they no longer need better coverage inside your house.

  • The HiBoost 10K system I bought definitely works, but we have such a weak signal where we live. I was wondering if the Cel-Fi GO X might be a better option? Do you think we would see a significant difference with that model instead? If so, I would be interested in getting that model and returning this one for a refund. Please let me know. I'm happy to discuss on the phone too, if that is better.

    Yes, Cel-Fi Go-X is definitely more powerful providing up to 100 dB Gain increase versus up to 70 dB Gain increase that HiBoost kit provides. That is a huge difference. But the cost of Cel-Fi is considerably higher too. It is your choice. Yes, you can order the Cel-Fi now to try and see if it is worth the cost. If it is, then you can return HiBoost within 60 days of purchase for a full refund.

  • I presently have a parabolic directional grid antenna on a 40 ft. tower and a weboost booster. I use it to receive my wifi from AT&T tower. Will the Cel-Fi indoor outdoor cell booster work with my setup?

    Sorry, you can only use the complete Cel-Fi kit instead of the complete weBoost kit. Additionally, there may be impedance mismatch because some weBoost models require 75 Ohm exterior antennas because they have 75 Ohm exterior antenna ports whereas Cel-Fi kits require 50 Ohm antennas as they have 50 Ohm exterior antenn port.

    Per FCC regulations, we cannot sell you just the main Cel-Fi amplifier unit for use with your current grid antenna and cables set-up with weBoost amplifier. You must install any complete FCC certified cellular amplifier kit as packaged and sold. The reason is that entire system is calibrated to provide max output that is safe and legal per current wireless telecommunication laws. It is for our health and safety as well as to protect wireless networks from getting damaged.

    If that is not what you were asking, please contact us and provide more details and we will be glad to help. Thank you.

  • I ordered model CELFI-GOX-1D today and wanted to check what the difference is vs. the AT&T specific model since I will be using an AT&T service.

    Thanks for your purchase. You should see no difference between the two boosters as you can select the carrier on the booster through the Cel-Fi wave app. In fact if you purchased the "carrier specific" product, you still could change the carrier in the setting of the app.

  • Going to check with AT&T and make sure they won't object to using device and permit register. Using a Mofi4500 modem / router with AT&T sim using band 2, 4, 5, 12, 17 and 30. I have tested and already have RSRP / SINR info for my site location. Mofi 4500 set up with dual mimo yagi antennas - can send info. Will the separate booster Cel-FI Go X external antenna and internal antenna help my stand-alone separate Mofi modem / router reception for data transfer rates for Internet? Internet works but data transfer rates are not reliable especially given inclement weather. Everything else already works for voice and data on iphones.

    Yes, the Cel-FI Go X cell phone signal booster with exterior and interior antenna will help increase speed of your standalone separate MoFi modem or router reception for wireless data transfer.

    All major carriers allow registration of cell signal boosters as stated in our registration guide at https://www.signalbooster.com/pages/register-cell-phone-signal-booster per respective Carrier's simple registration process as detailed at their respective websites. Therefore, this implies that all major carriers that own their own wireless networks allow use of only FCC registered signal boosters which is all we carry, on their network. Please read following information for confirmation of the same from the respective major service providers:

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles of your home / building. Please check outside signal level in decibels before ordering. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

If it is too weak, submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

Please note: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
