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 does a mobile signal booster do? - A mobile signal booster helps improve the mobile phone signal in your home or office. It catches the outside signal, amplifies it, and then sends it inside so you can enjoy clearer calls and faster internet. This is very helpful if you find that your calls drop often or if your internet is slow.
- Which networks does the Alcom mobile signal booster support? - The Alcom mobile signal booster works with multiple networks in Finland. It supports both 3G signals from networks like Telia, Elisa, and DNA, as well as 4G LTE signals from Alcom. This means if you have a compatible phone, you can enjoy better service no matter which network you use.
- How big of an area can the booster cover? - This signal booster can cover an area up to 200 square meters. This makes it ideal for smaller apartments or offices where several people might be using their phones at the same time.
- Do I need to have a signal outside for the booster to work? - Yes, the booster needs some signal from the outside to work effectively. If there is no signal at all outside, the booster won't be able to help. It can't create a signal, only amplify an existing one.
- How can I check if my phone supports 4G Calling? - To find out if your phone supports 4G Calling, you can dial *3001#12345#* and press call. Then, go to 'Serving Cell Info' to see the 'Freq Band Indicator'. This will show you if your phone can use the 4G network for clearer voice calls.
- Is it easy to install the mobile signal booster? - Yes, the kit comes with everything you need, including aerials, cables, and a booster unit. You just need to follow the instructions provided, and it is designed to be easy enough for anyone to install.
- What if I need longer cables for installation? - If the standard 10-meter external cable is not enough for your installation, you can upgrade to a longer cable. This will help ensure that your signal booster works effectively, even in larger spaces.
- What is a lightning surge protector? - A lightning surge protector is an extra device that helps protect your signal booster from damage caused by lightning strikes. It can handle strong electrical surges, ensuring that your equipment remains safe and functions properly.
- Can I use the booster if I travel to different areas? - Yes! As long as there is a signal in the area you travel to, you can use the booster to improve your phone's reception wherever you are. Just make sure to install the external antenna in the best signal spot.
- What happens if multiple people are using the booster? - The Alcom mobile signal booster can support up to 20 users at the same time. This means that if you have family members or colleagues using their phones, they can all enjoy improved signal strength and internet access together.
