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.
- Outside Antenna: Pulls in tower Signal.
- Signal Booster: Amplifies the Signal.
- Inside Antenna: Re-broadcasts Signal.
- Mobile Phone: Gets Boosted Signal.

Installation

Application Scenarios




- What is a mobile signal booster? - A mobile signal booster is a device that helps improve the mobile phone signal in areas where reception is weak. It works by capturing the existing signal from outside, amplifying it, and then transmitting it inside your car or building. This helps you make clearer phone calls and use data smoothly.
- How does the 3G signal booster work? - The 3G signal booster uses two frequencies: 900MHz and 2100MHz. When installed in your vehicle, it captures the outside mobile signal and strengthens it. This allows you to have better voice clarity, faster internet browsing, and sends/receives messages without interruptions.
- Is this booster compatible with all phone networks? - Yes! This mobile signal booster works with major phone networks in Singapore, including SingTel, StarHub, M1, and Circles.Life. It helps improve 3G, 2G voice calls, and text messages for all users in the vehicle.
- Do I need to have signal outside for the booster to work? - Yes, the booster requires some signal from outside to amplify it inside. If there's no mobile signal outside, the booster cannot create a signal, meaning it won't work effectively.
- How do I know if my signal frequency is Band 8 or Band 1? - You can check your phone's frequency band by dialing *3001#12345#* and pressing the call button. Then tap on 'Serving Cell Info' to view the 'Freq Band Indicator'. Alternatively, you can use apps like CellMapper or Network Signal Info Pro to find this information.
- How many people can benefit from the signal booster simultaneously? - The signal booster can support up to 15 users at the same time. This is great for families or groups traveling together, ensuring everyone can enjoy a strong mobile signal inside the vehicle.
- Is it difficult to install the signal booster? - Not at all! The signal booster comes with an easy-to-follow installation manual, and you won't need any special tools or expertise. Just follow the steps, and you'll have it set up quickly!
- What happens if I don't need the booster anymore? - If you no longer need the booster, you can easily unplug it or remove it from your vehicle. This ensures there is no radiation when the device is not in use, making it environmentally friendly.
- Does using a signal booster reduce mobile phone radiation? - Yes! A good signal coverage provided by the booster can reduce the radiation intensity that your phone emits when making calls. This helps in minimizing potential harm from mobile phone radiation.
- What does the kit include? - The complete kit for the mobile signal booster includes everything you need: a car signal booster/amplifier, an external magnetic-mount aerial, a 12V DC car power adapter, and an easy-to-follow installation manual. This ensures you have all parts required for installation in one package.
