RF transceiver modules are a type of radio frequency (RF) reference technology that enable the transmission of radio signals. SG901-1028 is a kind of radio frequency transceiver module designed to the GSM/GPRS900/1800MHz network band. It is a complete module packed with options, including those needed to develop high performance GSM/GPRS 900/1800MHz related applications.

Application Field of SG901-1028

SG901-1028 has a wide array of applications. Firstly, it can be used in access control and construction site management systems, which require the tracking and identification of moving objects like trucks, containers, pallets etc. with the help of GSM/GPRS 900/1800MHz technology. Secondly, it can be used in utility applications, such as water and gas meters, where the data is sent to the central billing server over 900/1800MHz networks. SG901-1028 can also be used in any of the applications that need location tracking, such as security systems, fleets, school buses, and so on.

Working Principle of SG901-1028

The SG901-1028 is a fully integrated GSM/GPRS 900/1800MHz transceiver module that works as a bridge between the device and the cellular network. It consists of a baseband processor and an RF transceiver for communicating with the cellular network based on the GSM/GPRS protocol. It has a wide range of operating capabilities, including voice, SMS, audio, and packet-switched data communication, as well as on-board SIM functionality.

The working principle of the SG901-1028 module is simple: The modem initiates GSM/GPRS connection with the cellular network and sends data as packets over the network. It then receives data from the server along with some control commands in the form of packets. This data is then decoded and processed, and the modem uses the corresponding transmit frequency and power to send the data. The modem then receives data from the network and sends it to the device. The device, in turn, processes the data according to the protocol and sends it back to the modem.

In addition, the SG901-1028 comes with a set of powerful features that provides support for a variety of applications, including location services, PPP support, remote actuation, and monitoring. It also supports a wide range of GSM bands used in different countries, as well as different microcontrollers, so that it can be used for a variety of applications.

Conclusion

The SG901-1028 is a powerful and versatile RF transceiver module designed for GSM/GPRS 900/1800MHz technology applications. Its application field covers access control, construction site management systems, utility metering, location tracking, and a number of other applications, and its working principle is also relatively straightforward. As such, the SG901-1028 is a reliable choice for any GSM/GPRS 900/1800MHz related projects.
