Digital Band Selective 2G 3G Cell Phone Repeater, 4G Amplifier 5G Mobile Phone Signal Detector
Product Overview
2G 3G 4G repetidor de celular 4g amplificador celular repetidor 5g mobile phone signal detector
General Description
The Repeater provides an affordable solution to solve indoor signal coverage problems caused by signal fading and attenuation due to architectural obstacles. Its easy installation and maintenance help carriers achieve fast return on investment.
The repeater functions as a relay between the BTS and mobile devices. It captures the strongest signal from BTS via the Donor Antenna, linearly amplifies the signal, and retransmits it via the Indoor Signal Distribution System to weak or blind coverage areas. Mobile signals are also amplified and retransmitted to the BTS in the opposite direction.

Company Introduction
Shenzhen ATNJ Communication Technology Co., LTD
Shenzhen ATNJ Communication Technology Company was founded in Nanshan District, Shenzhen in 2010 with over 900sqm factory. ATNJ focuses on the production and development of micro power signal booster, wireless signal repeater, Indoor Signal Distribution System and antenna series. With professional engineers, workers and senior management personnel, the group maintains high-speed development.
Meanwhile, up-to-date facilities and technology ensure the business long-term development. With the rapid development of the company, ATNJ moved to Guangming District, Shenzhen in 2016 with a bigger factory over 2800sqm and over 50 workers.
In its stage of rapid development, ATNJ advertised its products by attending trade exhibitions overseas, cooperating with many platforms like Made-in-China, Global Sources and others. ATNJ attended Mobile World Congress in Spain, which made ATNJ well known worldwide and through MWC, ATNJ started to cooperate with many overseas companies.
Nowadays, ATNJ not only produces and develops high-quality home use signal booster and high power wireless repeater, but also expands its business scope to cooperate with signal operators, providing signal coverage solutions for large areas like residential areas, office buildings, supermarkets, underground garages and rural areas.
With the popularization of signal repeaters, users have more requirements for functionality. In 2020, ATNJ developed smarter digital module signal repeaters with WIFI connection monitoring function, allowing users to control the signal repeater and monitor its working status with their mobile phones. Signal repeaters with WAN connection/Bluetooth connection/USB connection were developed simultaneously.
In 2021, 5G signal booster was developed and successfully introduced to the Chinese market. Additionally, ATNJ started upgrading signal boosters from analog module to digital module, enabling products (micro power signal booster, wireless signal repeater, Indoor Signal Distribution System) to be operated and controlled with WIFI connection, WAN port, USB port and SIM card.
Furthermore, more functions are equipped in our products, like band selective, sub bands, OLED screen display, and MGC. With ATNJ's technological progress, easier-to-use and more functional signal boosters continue to be developed.

Frequently Asked Questions
| Do you have CE or any other certification? | Yes, we have CE, ROHS and CCC certification, etc. |
| Can you give me a discount? | Please discuss with our sales team. |
| How about gain and output power of your device? | Different models have different gain and output power specifications. For more details, please contact us. |
| How long is warranty period? | The warranty is 36 months. And we offer 7*24 technical support. |
| How many square meters can be covered? | Coverage area varies by model. Different models cover different square meters. |
| How does a cell phone signal booster for office differ from residential signal boosters? | Building boosters for office installations differ from residential boosters in that they can cover much larger areas. Residential cell phone signal boosters cover smaller areas, require less power, and are typically easy to self-install. Office cell phone signal boosters need to cover larger areas, handle more users, and power a full DAS system with multiple antennas covering the entire office space. |
