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 purpose of the 500m2 Mobile Booster? - The 500m2 Mobile Booster is designed to enhance mobile phone signal, specifically for voice calls and text messages, using the 900MHz frequency. This frequency is commonly used by mobile networks in the Czech Republic, including Vodafone, T-Mobile, and O2. By boosting the signal indoors, it ensures clearer calls and quicker text sending, making it ideal for medium-sized homes or offices.
- How does the mobile booster work? - The mobile booster works by amplifying the existing mobile signal from outside and redistributing it inside your building. However, it cannot create a signal where none exists. If there is no signal outside, the booster will not be able to help, so it's important to ensure adequate reception outside before purchasing.
- What areas can the 500m2 Mobile Booster cover? - The 500m2 Mobile Booster provides coverage for areas up to 500 square meters. This makes it suitable for medium-sized homes, offices, warehouses, and similar spaces where improving mobile reception is necessary.
- What should I do if I'm not sure my phone runs on the 900MHz frequency? - If you are unsure whether your phone uses the 900MHz frequency, it is advisable to check with your mobile carrier. Alternatively, you can download an app like 'Network Signal Pro' to verify the frequency your phone operates on.

This includes the booster unit, an external antenna, an internal antenna, a power adapter, and a 10-meter outdoor cable. You won’t need to buy anything separately.
- Can I upgrade the external cables or aerial included in the package? - Yes, if the included 10-meter external cable is not long enough for your needs, you can upgrade to a longer length. There are also options to upgrade the external aerial to a higher gain Yagi antenna for improved performance, especially in areas where the signal is weak.
- What protection does the booster offer against lightning? - To protect your mobile booster setup from lightning strikes, you can add a Lightning Surge Protector. This device absorbs excess current caused by lightning and protects your equipment. It's easy to install and rated for substantial surge protection.
- How many users can the mobile booster support simultaneously? - The 500m2 Mobile Booster can support up to 50 users at the same time. This makes it suitable for both personal use and small businesses where multiple devices need improved signal strength.
- What type of signal does this booster improve? - The 500m2 Mobile Booster boosts 2G voice calls and text signals on the 900MHz frequency. It is specifically tailored for use with providers like Vodafone, T-Mobile, O2, and others operating within the Czech Republic.
- Are there any special considerations for installation? - While the installation of the mobile booster is designed to be straightforward, you should always follow the guidelines provided in the user manual to ensure optimal performance. Avoid placing the indoor antenna in areas where barriers can obstruct the signal.
