700MHz 800MHz Signal Booster For Mobile Phone 4G Repeater NR Cellphone Signal Apmlifier
A mobile signal amplifier, also known as a cell phone signal booster, functions as a device designed to enhance cellular signals for improved reception and transmission. The device operates on a relatively straightforward principle, aimed at boosting weak signals to provide better connectivity and call quality for users.
It is essential for mobile signal boosters to operate within approved frequency bands for cellular communication, ensuring compliance with regulations and preventing interference with cellular networks. Proper installation of the external and internal antennas is crucial for optimizing the booster's performance and effectiveness.
In essence, a mobile signal booster works by capturing weak cellular signals, boosting them through an amplifier, and redistributing the strengthened signals within a designated area to enhance connectivity and communication capabilities for mobile users.

How does it work?
Product Description
The repeater makes the signal stronger in places with poor signal coverage such as:
1) Underground areas: basements, parking lots, tunnels;
2) Other places where cellular signal is shielded by metal or concrete walls: offices, supermarkets, cinemas, hotels;
3) Places distant from the BTS like private houses.
Packaging Including:
1. LTE 700MHz 800MHz Dual Band Booster
2. Power adapter
3. Outdoor Log-periodic antenna
4. Indoor Omni antenna and Ceiling antenna
5. 5 meters cable
6. 15 meters cable
FAQ:
1. What is a cell phone signal booster?
A cell phone signal booster is a device designed to improve cellular signal reception and transmission in areas with weak signal strength.
2. How does a cell phone signal booster work?
A signal booster works by capturing weak signals through an external antenna, amplifying them with an amplifier, and rebroadcasting the strengthened signals via an internal antenna for improved connectivity.
3. Where can I use a cell phone signal booster?
Cell phone signal boosters can be used in homes, offices, vehicles, and other locations where there are issues with poor cellular reception.
4. Are cell phone signal boosters legal to use?
In many countries, cell phone signal boosters are legal as long as they comply with regulatory standards regarding frequency bands and power levels.
5. Do cell phone signal boosters work with all carriers?
Most cell phone signal boosters are compatible with major carriers and support multiple frequencies, but it's essential to check compatibility with your specific carrier before purchasing.
