How It Works

1
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster
2
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
3
Your devices get increased cell reception, and calls and data are fed through the booster back to the network.
Get stronger signal

Normal Cell Coverage
Dropped calls and slow data are generally caused by three things: distance from a cell tower, building materials in your home or office, or obstruction from tall objects such as trees, topography, and buildings.
Signal Coverage with our booster
Signal boosters increase cell signal by collecting signals with a powerful antenna, delivering those signals to the booster, amplifying the cell signals so your devices receive them, and delivering your device's boosted signals back to the cell tower.Installation
- Connect the indoor antenna to the MS port.
- Connect the outdoor antenna to the BS Port.
- Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
- Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
- Power on the booster and check the signal strength.
- Adjust the outdoor antenna until you get the best signal strength.
IMPORTANT NOTE:
DO NOT POWER ON THE DEVICE UNTIL YOU HAVE COMPLETED THIS SETUP.

- What is a mobile signal booster? - A mobile signal booster is a device that helps improve the mobile phone signal in areas where the signal is weak. It takes the weak signal from outside, boosts it, and then spreads the stronger signal inside buildings like homes or offices.
- How does the 4G LTE & Calls Booster work? - The 4G LTE & Calls Booster works by picking up the existing weak mobile signal from outside your building and amplifying it. This stronger signal is then distributed throughout the indoor area, allowing you to make clear calls and use faster internet without interruptions.
- Is the booster compatible with all mobile networks? - Yes! The booster works with many mobile networks in Denmark, including Three, TDC, Telenor, Telia, and Oister. This means you can boost the signal for different types of phones and networks in one place.
- Can I use the booster if there is no signal outside? - Unfortunately, if there is no signal outside, the booster won’t work. It only amplifies signals that are already available, so you would need some signal from the outside to use it efficiently.
- How big of an area can the booster cover? - The booster can cover an area of up to 500 square meters. This makes it great for medium-sized homes, offices, or warehouses, ensuring that many people can enjoy better signal strength.
- How can I check if my phone supports 4G Calling? - You can check if your phone supports 4G Calling by dialing *3001#12345# and looking for 'Freq Band Indicator' in the 'Serving Cell Info' section on your iPhone. This shows whether your phone can use 4G for voice calls.
- What items are included in the booster kit? - The booster kit includes everything you need for installation: an external antenna to capture signals, cables to connect the parts, a booster unit to amplify signals, an internal antenna to spread the boosted signal inside, and a power adapter.
- What should I do if I need longer cables? - If the standard 10 meters of external cable is not sufficient for your area, you can choose to upgrade to longer cables. This helps ensure that your booster installation can reach the best signal areas outside.
- Do I need to upgrade my aerial for better performance? - If your phone shows only 1 or 2 signal bars indoors, it’s a good idea to upgrade to a higher gain aerial. This will allow the booster to pick up a stronger outside signal and work more effectively in your indoor space.
- What is a Lightning Surge Protector? - A Lightning Surge Protector is a safety device designed to protect your signal booster from damage due to lightning strikes. If you live in an area where storms are common, this protector can help keep your equipment safe.
