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 Calls - 2000m2 signal booster? - The Calls - 2000m2 signal booster helps improve mobile phone signals for voice calls and texting.

This device is really good if you have a large space, like an office or a big house, as it can cover up to 2,000 square meters.
- How does the signal booster work? - The booster takes the existing mobile signal from outside and makes it stronger inside your home or office. However, if there is no signal outside at all, the booster won't be able to help. It's designed to enhance weak signals, not create new ones.
- Can this booster work for all mobile networks? - Yes, this booster is compatible with several networks in the Czech Republic including T-Mobile, Vodafone, O2, and more, as long as they operate on the 900MHz frequency for voice calls.
