#### 1

**Receives signal**  
The powerful antenna reaches out to access a voice and 3G, 4G, and LTE data signal, and delivers it to the booster  

#### 2

**Boosts signal**  
The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.  

#### 3

**Broadcasts signal**  
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**

1.  Connect the indoor antenna to the MS port.
2.  Connect the outdoor antenna to the BS Port.
3.  Install the outdoor antenna and keep a minimum vertical distance of 10 meters from the indoor antenna.
4.  Point the outdoor antenna to the direction where you know there is possibly a higher signal strength from the base station.
5.  Power on the booster and check the signal strength.
6.  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.

1.  What is a mobile signal booster? - A mobile signal booster is a device that helps to improve weak mobile signals, allowing for better voice calls and text messaging. It works by receiving the existing signal from outside, amplifying it, and then broadcasting the stronger signal indoors.
2.  How does the 100m2 mobile signal booster work? - The 100m2 mobile signal booster amplifies mobile signals specifically on the 900MHz frequency, which is commonly used in Switzerland. It can improve signals for multiple networks, including Swisscom, Sunrise, and Yallo, ensuring clear voice calls and text messages within an area of up to 100 square meters.
3.  Who can benefit from using a mobile signal booster? - Anyone living in an area with weak mobile signals, such as small apartments or offices, can benefit from a mobile signal booster. It is especially helpful for people who frequently miss important calls or have difficulty sending messages due to poor reception.
4.  What comes in the installation kit? - The installation kit for the mobile signal booster includes everything you need: an external antenna, cables, the booster unit itself, an internal antenna, and a power adapter. This makes it easy to set up and improve your indoor signal.
5.  Can I install the booster myself? - Yes! The mobile signal booster is designed for easy installation. The kit comes with all necessary components and instructions, making it simple for anyone to set up and start enjoying improved signal strength without needing a professional.
6.  What should I do if there is no signal outside? - The signal booster amplifies existing signals, so if there is no signal outside, the booster will not work. Make sure to check your outdoor signal strength first. You can use specific codes on your phone to check this signal level.
7.  What does it mean to upgrade the external cables? - If the standard 10-meter external cable included with the signal booster isn't long enough for your setup, you have the option to purchase longer cables to ensure proper connectivity between the external antenna and the booster unit.
8.  Why should I upgrade to a higher gain antenna? - If your phone shows weak signal bars indoors, upgrading to a higher gain Yagi antenna can significantly improve performance. This upgrade is recommended if your outdoor signal strength is below certain levels, ensuring you get the best possible reception.
9.  What is the lightning surge protector for? - The lightning surge protector is an important safety feature that protects your mobile signal booster from damage caused by lightning strikes. It safely absorbs high amperage surges, ensuring your device remains operational even during storms.
10.  How many users can connect to the booster at once? - The 100m2 mobile signal booster can support up to 10 users simultaneously. This means that multiple people in your home or office can enjoy improved signal strength for their calls and texts at the same time.
