Building vertical industry application of Internet of Things based on NB-IoT…
As we all know, wireless modules have two common performances. The following small series with outstanding skills will introduce the comparison of the two performances.As an important brand soul of the company, Wireless Module Has outstanding performance, through the market test, still has a strong development trend. https://www.hkulike.com/ Firstly, the instantaneous frequency of the…
Application process of RTK radio network modeIn combination with these conditions, RF Module It can still let us see good development and bring fresh vitality to the whole market. https://www.hkulike.com/ 1, instrument erection Complete the hardware erection and configuration of the reference station and mobile station, and build the hardware environment for the…
The working frequency of the wireless transceiver module is 315MHz or 433MHz (there are other special frequencies), and the SAW resonator is used to stabilize the frequency, so the frequency stability is extremely high. When the ambient temperature changes between-25 and+85 degrees, the frequency drift is only 3ppm/ degree. It is especially suitable for wireless…
The wireless transceiver module is mainly used for signal transmission to achieve multi-functional purposes such as communication and wireless control. General wireless modules are used in a variety of occasions, and the following mainly introduces three kinds.know radio Module Our growth has to go through many hardships, but entrepreneurs are never afraid and boldly move…

The most basic usage of GPRS DTU is: put a SIM card with GPRS function in DTU, after DTU is powered on, first register to GPRS network, and then establish connection with data processing center through GPRS network. After the GPRS DTU is powered on, first read the working parameters saved in the internal FLASH…
If the mobile phone uses GPRS DTU on the Internet, data can be sent and received in groups, which means that users are always online and charged according to traffic, which quickly reduces the service cost. If CSD bearer is changed to GPRS, it means that dozens of people will bear the cost of the…
