What is a 4G LTE Mobile Signal Booster? - A 4G LTE Mobile Signal Booster is a device that helps improve the strength of your mobile phone signal, especially for 4G LTE services. It works by amplifying existing signals from nearby cell towers, making it easier for your phone to connect and communicate effectively. This is particularly useful in areas where the signal is weak. 2. How does the 4G LTE Booster Benefit My Calls? - If your phone supports 4G Calling, also known as VoLTE, this booster allows you to make clearer voice calls. With a stronger signal, the sound quality of your calls improves significantly, making it easier to have conversations without interruptions. 3. What areas can the booster cover? - The booster is designed for medium-sized areas, specifically to boost signals in spaces up to 250 square meters. This makes it ideal for homes, cafes, restaurants, pubs, and clubs, ensuring that everyone can enjoy a better signal indoors. 4. How do I check if my phone supports 4G LTE? - To check if your phone supports 4G LTE, you can do this by dialing \*3001#12345#\* and pressing the Call button. Then, look for 'Serving Cell Info' and find the 'Freq Band Indicator'. It should show a '20' if your phone supports Band 20. 5. Can the booster create a mobile signal? - No, the signal booster cannot create a mobile signal. It can only strengthen existing signals. If there's no signal outside, the booster will not function properly. It's important to have at least some signal for the booster to work effectively. 6. What comes in the booster kit? - The kit includes everything you need for installation: the booster unit, an outdoor antenna, an indoor antenna, a power adapter, a 10-meter outdoor cable, and a 5-meter indoor cable. Everything is included for one price, making it convenient for users. 7. Do I need to upgrade the external cables? - If the standard 10-meter cable length isn't long enough to reach your desired area, you have the option to upgrade to longer cables. This will ensure that your outdoor antenna can be placed in a location where it can pick up a better signal. 8. When should I consider upgrading my external aerial? - You might want to upgrade to a higher gain Yagi antenna if your phone shows only 1 or 2 signal bars inside your home, or if you're located in an area with weak outdoor signal strength for 2G, 3G, or 4G services. 9. Why should I use a surge protector? - Using a lightning surge protector is important as it protects your equipment from damage caused by lightning strikes. It’s easy to install and essential for keeping your booster safe from high voltage surges that can occur during storms. 10. How many users can the booster support simultaneously? - The booster can support up to 25 users at the same time. This makes it a great option for families or businesses where multiple people need reliable mobile service at once.
