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 strength of your phone's signal. It takes weak signals from outside and makes them stronger inside your home or office. This allows you to make calls, send texts, and use the internet more easily, especially in areas where the signal is weak.
- How does the 3G & 4G LTE booster work? - This booster works by capturing the mobile signals from outside and amplifying them. It operates on specific frequencies used by mobile networks, namely 1800MHz and 2100MHz, which are common in Romania. Once the signal is boosted, it provides better connectivity for 3G and 4G services, making your calls clearer and your internet faster.
- Who can benefit from using this booster? - Anyone struggling with poor mobile signals at home or in their offices can benefit from this booster. It's particularly useful for families with different mobile network providers, as it supports multiple networks simultaneously. If you often have dropped calls or slow internet, this booster might be just what you need.
- How large of an area can this booster cover? - The 3G & 4G LTE booster can effectively cover an area up to 500 square meters. This makes it ideal for medium-sized homes, offices, warehouses, or other spaces where signal strength needs enhancement.
- What if I don't have any signal outside? - The booster can only strengthen a signal that already exists. If there is no signal outside, the booster will not work. You need to have at least a weak signal outside for the booster to amplify it inside.
- How can I check if my mobile phone is compatible? - To check if your phone works with the booster, you can use your iPhone to dial *3001#12345#*. After pressing the Call button, click on 'Serving Cell Info' to find the 'Freq Band Indicator'. Alternatively, you can use apps like 'CellMapper' to verify compatibility.
- Is installation difficult? - Not at all! The kit comes with everything you need for a complete installation, including outdoor and indoor antennas, cables, and a power adapter. The installation process is designed to be straightforward, so you can set it up easily without professional help.
- Can I upgrade my booster or cables? - Yes, you can! If the standard 10-meter outdoor cable is not long enough for your area, you have the option to upgrade to a longer cable. Additionally, there are optional surge protectors available to guard your equipment against lightning strikes.
- Will the booster improve my internet speed? - Yes, the booster can help improve your internet speed by enhancing the 4G LTE signal. This means you can enjoy faster uploads and downloads, making your online activities smoother and more efficient.
- How do I know if I need a high-gain antenna? - If your phone shows low signal strength (like 1 or 2 bars), a high-gain antenna might be helpful. The included kit typically comes with a high-gain Yagi antenna, which provides better performance, especially if you're in an area with weak signals.
