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.

Application Scenarios




- What is a 4G LTE signal booster? - A 4G LTE signal booster is a device that helps improve the mobile signal in your car. If you're having trouble with weak phone signals or dropped calls, a booster can make your calls clearer and help you get a stronger data connection for using the internet.
- How does the signal booster work? - The signal booster works by capturing the existing outside mobile signal and amplifying it inside your vehicle. This means that if there's some signal outside, the booster can help make it stronger for you to use while you're inside the car.
- Will the booster work for all phone networks? - Yes! This booster is designed to work with many phone networks like A1, Three, T-Mobile, Orange, and more. It enhances the signal for anyone using these networks, making it great for families or groups in one car.

- What happens if there’s no signal outside? - If there’s no signal outside your vehicle, the booster won’t be able to help because it can only amplify existing signals. It won’t create a signal where there’s none, so it's important that there is some level of outside signal.
- Can I use the signal booster for voice calls? - Yes! The booster helps improve voice calls by making them clearer and reducing the chances of dropped calls. If your service provider supports 4G Calling, the booster can enhance that as well.
- Does the booster affect battery life? - Not really. The signal booster does use some power, but it’s designed to be efficient. You can use it while driving, and it won’t drain your car’s battery or your phone's battery quickly.
- What is the size of the booster? - The booster is small and compact, about the size of a cigarette box. This makes it easy to carry and convenient to fit into various spaces in your vehicle without taking up much room.
- How many people can use the booster at the same time? - The signal booster can support up to 15 users at the same time. This means it's perfect for families or groups traveling together who all need better mobile coverage.
- Are there any health concerns with using a signal booster? - Using a signal booster can actually help reduce your mobile phone's radiation by improving the signal strength. The device itself is designed with low radiation, making it a safer choice for you and your passengers.
