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.
