In radio technology, basically three characteristics can be used to characterize a radio network: ● Range/distance ● Data transfer speed ● Power consumption. The criteria for these three indicators are certainly not the same, since the laws of physics set…
How the serial port server works
How the serial port server works After the invention of the USB protocol, serial port devices are rarely seen in our lives. For this reason with modern transmission systems, most manufacturers no longer add serial ports to laptops, desktop computers,…

Common communication methods in the Internet of Things
Two-way communication Usually the serial port on the PC is a full-duplex device, which means it can send and receive data at the same time. To do this, it uses separate lines to send and receive data. Some types of…
Il principio di funzionamento e gli scenari di applicazione del GPRS DTU
GPRS DTU is also called gprs data transmission terminal. It is a gprs networking device formed by the gprs module embedded on the circuit board and a sheet metal shell. It is a wireless version of the serial port server.…
Il gprs dtu richiede una scheda?
Basic usage of DTU DTU initiates a TCP/IP communication request to the data center through the data center’s IP address, port number and other parameters. After receiving the response from the remote server, DTU implements remote networking requirements, maintains data…
Architettura della rete LoRa
The Internet of Things (IoT) is considered to be the third wave of development of the world’s information industry after computers and the Internet, and is also called the fourth technological revolution . At present, most of the Internet of…
Advantages of LoRa in Cellular and LAN
Local area networks such as WiFi or Bluetooth are already mature technologies. There are well-established standards for this type of small wireless communication, such as WiFi, Bluetooth 4.0, Zigbee and Z-Wave. But the biggest problem with many LANs/Personal Area Networks…
