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 4G LTE mobile signal booster? - A 4G LTE mobile signal booster is a device that helps improve the 4G LTE signal strength, allowing for stronger mobile signals in your home or office. It works by taking weak signals from the existing mobile network and amplifying them, making it easier for your devices to connect and enjoy faster internet.
- How does the signal booster work? - The booster captures weak signals from outside and amplifies them to provide stronger coverage inside your space. It requires some signal from outside to work; if there's no signal, the booster won't be able to help. For best results, make sure there's at least a little signal outside.
- How big of an area can this booster cover? - This 4G LTE booster is designed to cover an area of up to 2,000 square meters. That makes it suitable for large houses, offices, and even hotels, ensuring a reliable mobile connection throughout that space.
- Is the booster difficult to install? - No, the mobile signal booster is easy to install and comes with everything you need, including an external aerial, cables, and a power adapter. If you follow the provided instructions, you can set it up even if you are not tech-savvy!
- Can I use the booster with any mobile network? - The booster is specifically designed to work with the Telekom and Cosmote networks in Romania that operate on the 1800 MHz frequency. If your mobile network uses a different frequency, this booster may not work for you.
- How do I check my mobile frequency band? - To check your frequency band, you can use your iPhone. Dial *3001#12345#* and press the call button. Then, tap on 'Serving Cell Info' and look for the 'Freq Band Indicator.' This will tell you what frequency your phone is currently using.
- What upgrades can I add to the booster kit? - You can upgrade your setup with a longer external cable if the standard length isn’t enough. You can also choose a higher gain Yagi antenna for better performance, especially if you often see only one or two signal bars on your phone.
- What is a lightning surge protector? - A lightning surge protector is an accessory you can add to safeguard your signal booster from damage caused by lightning strikes. It’s easy to install and protects the equipment from power surges, ensuring it works properly even in bad weather.
- Can multiple users use this signal booster at the same time? - Yes! The 4G LTE booster can support up to 200 simultaneous users. This means many people can enjoy improved mobile services at the same time, making it great for offices or larger gatherings.
- What should I do if the booster doesn't seem to work? - If the booster isn't working, first ensure that there is some signal outside. If there's little to no signal, the booster can't amplify anything. Also, check that the installation was done correctly, as this can affect performance. If problems persist, you might want to consult a technician for further assistance.
