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 - 1000m2 Mobile Signal Booster? - The Calls - 1000m2 Mobile Signal Booster is a device that helps improve the mobile phone signal in your home or office. It works especially well with the DTAC network in Thailand. This booster can cover an area up to 1,000 square meters, making it perfect for large spaces like houses, offices, and warehouses.
- How does the mobile signal booster work? - The mobile signal booster captures weak signals from outside and amplifies them, then broadcasts them inside your home or office. This way, you can enjoy clearer voice calls and faster texting, even in areas where the signal is usually weak.
- What types of services does the booster support? - This signal booster supports voice calls and SMS texts. It specifically enhances the 2G services on the 1800MHz frequency, which is used by DTAC in Thailand. So, you can expect improved call quality and message delivery.
- Can I install the signal booster myself? - Yes, you can easily install the signal booster using the included instructions. The kit comes with all necessary components, like antennas and cables. It's simple; you can do a 'loose' install first to find the best positions before fixing everything in place.
- What should I do if there is no signal outside? - Unfortunately, the signal booster cannot create a signal. If there is no signal outside, the booster won't work. It needs at least a weak signal to amplify it. Try to install the outdoor antenna in a spot where there is some signal available.
- What if I need a longer cable for installation? - If the standard 10-meter outdoor cable is not enough for your setup, you can choose to upgrade to a longer cable when you purchase the booster. Longer cables are available in options such as 20m, 30m, 40m, and 50m.
- How can I check if my phone is using the correct frequency band? - To ensure your phone is on the correct band for this booster, dial *3001#12345# on your phone and press call. Then select 'Serving Cell Info' and check the 'Freq Band Indicator'. You can also use apps like 'CellMapper' to check the frequency.
- What is the benefit of upgrading to a higher gain antenna? - Upgrading to a higher gain Yagi antenna can improve the performance of the booster, especially if your mobile phone often shows only 1 or 2 signal bars indoors. It’s especially beneficial if you notice weak signals from outside.
- What is a lightning surge protector? - A lightning surge protector is an additional accessory you can add to your signal booster system. It protects your equipment from damage caused by lightning strikes. It's a wise choice if your outdoor antenna is installed at a higher position, like on a roof.
- Can I use this booster for other networks in Thailand? - The Calls - 1000m2 Mobile Signal Booster is specifically designed for DTAC networks on the 1800MHz frequency (2G). It might not work as effectively with other carriers, so make sure to check compatibility if you use a different network.
