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 the 4G LTE Mobile Signal Booster? - The 4G LTE Mobile Signal Booster is a device designed to improve mobile signal strength for 4G LTE networks, specifically for Telekom and Cosmote users in Romania. It enhances the signal within an area of up to 300 square meters, making it ideal for homes, cafes, and restaurants.
- How does the 4G LTE Signal Booster work? - The signal booster takes the existing weak mobile signals from outside, amplifies them, and then broadcasts the stronger signal indoors. It needs to be installed with an outdoor antenna where there's some signal to work effectively.
- Can this booster work if there is no signal outside? - Unfortunately, no. The booster amplifies signals that are already present. If there is no signal from the outside, the booster cannot create one.
- What is included in the installation kit? - The installation kit includes everything you need: an external antenna, internal antenna, booster unit, power adapter, and a 10-meter outdoor cable. All these items are essential for setting up the device.
- Is the installation of the booster complicated? - Not at all! The installation process is straightforward. Just follow the step-by-step instructions provided in the kit, and you can set it up in no time!
- How many users can connect to the signal booster? - The 4G LTE Mobile Signal Booster can support up to 30 users simultaneously, allowing multiple devices to enjoy better signals in the boosted area.
- What do I do if I need a longer cable for installation? - If the standard 10-meter outdoor cable is not enough for your installation, you can upgrade to longer cable options like 20, 30, 40, or even 50 meters during the purchase process.
- How can I check my phone's frequency band? - To check your phone's frequency band, you can dial *3001#12345#* on your iPhone and press call. Then, tap on 'Serving Cell Info' to see the 'Freq Band Indicator'.
- Can I upgrade to a better antenna? - Yes, you can upgrade to a higher gain Yagi antenna. This is especially recommended if you notice that your phone has weak signal strength (1-2 bars) indoors.
- How do I protect the booster from lightning? - You have the option to add a Lightning Surge Protector when purchasing your booster. This device helps protect the equipment from sudden voltage spikes caused by lightning strikes.
