Technical Specifications
1. Smart LCD, show the real-time signal strength.
2. Sleeping Mode: When no user calls, the device works in Sleeping mode, so as to achieve the purpose of energy saving.
3. ALC(Automatic Level Control): Automatically adjust the output gain down to optimal figure while the output gain is above the optimal figure by the ALC circuit, this can greatly optimize the calling and data transfer quality.
4. AGC (Automatic Gain Control) : When the downlink output signal is too strong or self-oscillated, booster can automatically reduce the gain and reduce the interference signal.
5. MGC (Manual Gain Control): In order to install the booster conveniently, all frequency band of the booster have the Gain attenuation adjustment function, the adjustment scope is 0-27dB.

A mobile phone signal repeater provides the ultimate solution in any area where cellular communications can not work well due to leak of signals. The repeater device features easy installation & operation, build-in indoor antenna and no interference.
It could also improve indoor electromagnetism environments, protract cellular battery life and reduce radiation of cellphones. A mobile phone repeater is ideal for house, home, office use.
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.
Company introduction
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 with senior management personnel, the group maintains high-speed development.
Meanwhile, the Up-to-date facilities and technology end sure 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 oversea, cooperating with many platforms like Made-in-China, Global Sources and so on. Especially, ATNJ attended Mobile World Congress in Spain, which made ATNJ well known in the world and through MWC, ATNJ started to cooperate with many oversea 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, provide signal coverage solution for large area like residential area, office building, supermarket, underground garage and rural areas.
With the populization of signal repeater, users have more requirements for the functions of the signal repeater. In 2020, ATNJ developed smarter digital module signal repeater with WIFI connection monitoring function, with which users could control the signal repeater and watch the siganl repeater working situation with their mobile phone. Signal repeaters with WAN connection/Bluetooth connection/USB connection were developed at the same time.
In 2021, 5G signal booster was developed and put into Chinese market successfully. In addition, ATNJ starts to upgrade the signal booster from analog module to digital module, with which the products (micro power signal booster, wireless signal repeater, Indoor Signal Distribution System) could be operated and controlled with WIFI connection, WAN port, USB port and SIM card.
What's more, more functions are equipped in our products, like band select, sub bands, OLED screen display, MGC. With the progress of science and technology of ATNJ, easier use and more functional signal boosters have being developed.
We are manufacturer, and have our own factory.
