ATNJ network repeater NR mobile signal repeater 4G 5G cellphone signal booster repeater
A mobile signal amplifier, or cell phone signal booster, functions by capturing weak cellular signals through an external antenna, amplifying these signals using an amplifier, and rebroadcasting the strengthened signals via an internal antenna within a specific coverage area. This process enhances cell phone reception, reduces dropped calls, and improves data speeds for users by boosting the signal strength and extending cell phone coverage. Proper installation and compliance with frequency regulations are essential for optimal performance.

How does it work?
1. RECEIVES SIGNAL
 The powerful antenna reaches out to access a good signal, and delivers it to the booster.
 
 2. BOOSTS SIGNAL
 The booster receives the signal, amplifies it, and serves as a relay between your phone and the nearest cell tower.
 
 3. BROADCASTS SIGNAL
 Your devices get increased cell reception, and calls and data are fed through the booster back to the network.

Product Description



ALC functon
The ALC function can prevent excessive signal output and cause interference.


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.




FAQ:
 
 1. 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.
 
 2. 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.
 
 3. 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.
4. Can a cell phone signal booster improve data speeds?
Yes, by enhancing signal strength, a cell phone signal booster can improve data speeds for tasks like browsing the internet, streaming videos, and downloading files on your mobile device.
