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 strengthen your mobile phone signal. If you have trouble making calls or sending texts because of a weak signal, a signal booster can help. It takes weak signals from outside, boosts them, and then sends a stronger signal inside your house or office.
- How does the Calls - 500m2 booster work? - The Calls - 500m2 mobile booster works by capturing weak mobile signals from outside and amplifying them. It operates on a frequency called 900MHz, which many mobile networks in Finland, like Telia and Elisa, use. This means it can help improve your voice calls and text messages by providing a better connection indoors.
- How much area does it cover? - The Calls - 500m2 mobile booster can improve your signal in an area up to 500 square meters. This is big enough to cover medium-sized homes, offices, or warehouses, ensuring you have better reception wherever you are inside!

- What do I need to use the mobile booster? - To use the mobile booster, you need two main things: a good mobile signal outside your building and the booster kit, which includes an outdoor antenna, an indoor antenna, cables, and a power adapter. Once everything is set up, the booster will help you get a stronger signal inside.
- Will the booster work if I have no signal outside? - Unfortunately, a signal booster can only enhance existing signals. If there is no signal outside, the booster won't work. It needs at least a little bit of a signal to amplify it.
- How do I install the mobile booster? - Installing the mobile booster is quite easy! First, place the outdoor antenna in an area where you can get the best signal—like on your roof. Next, run the cable down to the booster inside. Then connect the indoor antenna, plug in the power supply, and you're done!
- Can I upgrade my booster? - Yes, you can upgrade your booster with additional options, such as longer cables or a better outdoor antenna. This is useful if you need to reach areas further away or if your mobile reception is particularly weak.
- What happens if my device gets hit by lightning? - To protect your signal booster from lightning, you can add a Lightning Surge Protector. This device helps shield your equipment from damage caused by lightning strikes, ensuring that your booster continues to work well.
- How can I check the signal strength on my phone? - To check your phone's signal strength, you can use a simple method! On an iPhone, you can dial *3001#12345#* and then press the call button. This will show you detailed information about the signal strength you are receiving.
