Dome Antennas are more popular because they project signal in all directions. Therefore, they are good for mounting on ceilings in central locations to project reception in 360 degrees fashion covering large square spaces.

Panel Antennas project signal in single direction. Therefore, they are good for installing on walls to cover rectangular areas like long corridors. They can be installed on ceilings to boost reception over multiple floors as they project reception downwards across multiple floors.

Expand indoor cellular coverage further by purchasing add'l in-building antenna kits that include required cables and splitter to connect to this booster kit.

Fusion7 by SureCall is an all in one consumer signal booster kit to help your indoor signal receptions that include cell phone, Wi-Fi, and HDTV! SureCall Fusion 7 consumer signal booster increases voice, text and 4G LTE signal strength for many simultaneous users in areas from 15,000 square feet to up to 20,000 sq. ft. This two in one cellular and WiFi signal catcher also works just the same for all cell phone brands like Apple iPhone, Samsung, LG, HTC, OnePlus, ZTE, Motorola (Moto), Google Pixel XL/ Nexus models, Kyocera, Blackberry, Microsoft Lumia, and Nokia.

It includes built-in Wi-Fi signal booster, along with a router that extends network coverage. Includes HDTV signal booster that brings locally aired HDTV television stations into large buildings. A Single Cellular + HDTV + Wi-Fi Signal Booster for up to 20,000 ft² (SureCall Fusion7) makes it easy to boost all types of signals without having to install and monitor multiple devices that clutter a home or office environment.

    Two Fusion7 kit configurations:

    1. A: SC-SEPTH/O-OD4-Kit: Outdoor Omni Antenna, 4 Indoor Omni Dome Antennas.
    2. B: SC-SEPTH/O-OP4-Kit: Outdoor Omni antenna, 4 Indoor Directional Panel Antennas.

    In the past when a person has had a weak signal for the phone or for the internet, the solution was to purchase either a cell phone signal booster for the home or to purchase a Wi-Fi booster. And while both of these products have proven to be effective in maximizing the signal strength, the problem that arises is that there is usually the need to purchase multiple boosters for a home. Commercial integrators have consistently complained about additional time, effort, and expense required for multiple wiring and additional equipment. If the cellular service is being blocked or weakened, then typically the internet signal will be blocked or weakened for the same reasons. Additionally, the technology trends and advancements signals on HDTVs are also a concern. SureCall has answered the demand of the public by offering the first all-in-one signal booster. This signal amplifier serves as a mobile as well as a Wi-Fi extender and booster to boost reception indoors for both those channels simultaneously! Currently, there're no other consumer grade wi fi boosters and extenders that do boosting of both such types of signals at the same time.

    Cellular Signal Specifics.

    The cellular phone signal allows for a signal boost of up to 10,000 sq. ft. with a weak outside signal of approximately 1 to 2 bars. It would offer signal boost to up to 15,000 sq. ft. with a medium signal outside of approx. 3 to 4 bars. It would offer boost in signal to up to 20,000 sq. ft. with a strong reception outdoors of approx. 5 bars.

    It is intended for all phones from all carriers including the latest 4G LTE phones. It also boosts 3G data and 2G voice plus texting which rely upon such signals. Fusion7 cell phone booster kit not only boosts, but it extends Wi-Fi for new and renovated buildings. The cellular uplink and downlink frequencies included make it compatible will all cellphones from all carriers such as Verizon, AT&T, Sprint, and T-Mobile in USA. These frequencies are:

    Uplink Frequencies.

    698-716/ 776-787/ 824-849/ 1710-1755/ 1850-1915.

    Downlink Frequencies.

    728-746/ 746-757/ 869-894/ 1930-1955/ 2110-2155.

    Supported Cellular Standards.


    Fusion7 incorporates the company's patent-pending seven-band technologies to deliver PCS and cellular frequency bands, AWS, and two LTE frequencies to support Verizon, AT&T and T-Mobile networks.

    Wi-Fi Signal Booster Specifics.

    Wi-Fi signals are based upon a number of factors; the signal booster works primarily by reading the signals within the 2.4-2.4835 frequency range. By combining the weak signals with the strongest signal and “reconditioning” that signal into a stronger band, the Wi-Fi is increased. There are a few specifications which should be noted. First, the Wi-Fi does not add to allotted data plans or service plans established in the contract between you and your internet service provider. Secondly, the device accessing the network must have the capabilities to access and function on the internet. For example: If a cell phone has minutes but does not have internet services activated in his or her plan, the person will not be able to access the internet. However, those which can access the internet can do so as long as the wi-fi is within the below specifications (which it is all across North America and elsewhere):

    Wi-Fi Standards.

    IEEE 802. 1 1b, IEEE 802 1 1g, IEEE 802. 1 1n.

    Wi-Fi Browsers Supported.

    Internet Explorer, Google Chrome, Mozilla Firefox, Safari, and others that exist.

    Security Specifications,

    WEP, WPS, WPA, WPA2, WPA2 Mixed.

    As you can see, most internet services, monitors, and providers will fall within this range. On the rare occasion that your Wi-Fi falls outside of the specifications above, contact your technician or cell phone signal boosters to ensure that the device will work properly. Also, before activating or installing your device check with your internet service provider about any restrictions to the network that the Fusion 7 booster may have, which is very unlikely.

    NOTE: Even though the signal is being boosted, the internet speeds will still be based upon the Wi-Fi data rate. Where the device can boost the rate to 150 Mbps (2.4 GHz), if the monitor and the service plan you have does not allot for this data rate, you may need to upgrade your plan in order to maximize the potential of the all-in-one signal booster.

    HDTV Signal Booster Specifics.

    The signal in the HDTV and the internet seem to be considered by most people the same thing, but they are not. The frequency range is different as well as the methodology in which a signal is gained and sent to the device. As such, a simple Wi-Fi booster would not be too effective (though you may see a slight increase in the signal) in most cases. Again, you will need to have a model specifically intended for HDTV service. Even if the device has a LAN or WAN port and a HDMI connector does not mean that the device is compatible with HDTV services. Therefore, this device boosts reception for up to 35 television set antenna’s over-the-air (OTA) HDTV signals to boost reception for TV channels and networks like PBS, ABC, NBC, Fox, and CBS. HDTV specifications are as follows:

    HDTV Supported Frequency Ranges.

    54-72/ 76-88/ 174-216/ 470-608/ 614-698.

    Maximum Output Power.

    3 Watt EIRP.

    Consumer Booster Installation Notice.

    This is a consumer device. Per FCC, you must register with your carrier after purchase.

    Soft Installation.

    Prior to committing to the installation of your Fusion 7 system, we suggest that you perform a soft installation. The soft installation involves setting (but not mounting) the device in the intended locations and then checking the signal coverage and strength.

    When performing your soft install, consider the placement and the number of antennas needed. Exterior and interior antennas should have a positive gain, preferably around +3. Generally, the OSL or outside signal level will between -50 and -100dBm. The signal will always be in the negatives in terms of the dBm. Where the dropped calls and signal strength is at is weakest is between the -85 to -100 dBm levels. So, if your antenna has a +3 gain which results in a -82 dBm you may want to consider another antenna or better placement.

    Interior placements should be at ceiling levels or high levels which are not obscured. Ensure that you have a 110 VAC outlet nearby and that the outlet is properly grounded. The device should NOT be placed within a tightly enclosed area or in areas which receive an abundance of heat (such as in the kitchen or the food court where the steam and heat could effect it). Once the strongest signal and position for the device has been established, have the device hard installed (mounted).

    Mounting the Booster.

    The booster amplifier or repeater is the core of the Fusion7 All-In-one Cellular, Wi-Fi, and HDTV booster. As such, it is important that the device is mounted in the best manner to maximize the signal boosting capabilities of the device. After detecting where the strongest signal is located, position your antennas accordingly. Prior to your hard install, mount the booster and test the system. The booster should be mounted by:

    • Using the mount screws provided and tightening them to a firm secured position. Do not use any screws which are not included with the device as they may go too far and damage the system. Do not overtighten the screws.
    • Use plywood of at least ¾” thickness mounted to the studs to secure the booster. Plywood must be level with the lights facing away from the wall/ceiling.
    • Connect the antenna cables for both the exterior and inside antenna at the specified ports.
    • After all cables are connected to the booster and to their appropriate antennas connect the powers.

    Testing the All-In-One Booster.

      The specific sectors of HDTV, Cellular, PCS, AWS, Wi-FI, etc. will be indicated on the device below the power button. Each sector has its own light which will indicate if that function is on and working properly. 

      NOTE: When you first turn on the booster it will flash yellow lights for about 10 seconds. Should there be any yellow lights after about 20 to 30 seconds, there is something which should be addressed. If at any point you see red lights on the system you should identify and fix this issue before conducting any further adjustments. Red lights are warning lights and should not be disregarded.

      Consumer Booster Considerations and Safe Guards.

      Where the all-in-one unit can help to boost the signal, it is important to understand what the system can and cannot do. The system is designed to give the most reception possible. However, it is unlikely that you will have 5 bars in all locations of the building (as this is practically impossible given the obstructions and structural considerations of most buildings).

      The Fusion 7 is equipped with a safeguard system which will automatically shut the system down if two or more red lights come on. If oscillation is detected a warning light will flash. Should the problem not be fixed in 15 minutes the system will shut down until further testing is performed.

      Questions & Answers


      Ask a Question
      • I have a 25,000 sqft metal warehouse that I need ATT cell coverage. There is absolutely no ATT cell coverage inside. The best reading I got outside was a -92dB. What is signal strength do I need OUTSIDE in order for this unit to work as advertised?

        If you're getting -92 dB on your phone, that sounds like a good start. A good way to know if the booster will work well with outside signal is if you can make and receive calls outside without the calls dropping or breaking up.

      • Will the Fusion 7 Booster work with other outdoor TV antennas? I live in a remote area and need an Omni-directional antenna.

        That kit will work with an omni directional TV antenna.

      • where does these units ship from

        They are in stock and will ship from our warehouse in Houston, Texas, USA.

      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. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. 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.

      Kevin K. of Anderson, California gave the following review:

      Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

      Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

      If outside signal is too weak (weaker than -110 dB), 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.

      For non installation-included kits: 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.
