There are many advantages to using an industrial router, DTU or switch, but as with any network connection, security is one of the most important elements when designing your system. We’ll look at several areas and where security gaps may…
How does the Internet of Things change our lives?
Internet of Things (IoT) – Essential IoT Business Guide The Internet of Things (IoT) is changing the way we live, work, travel and do business. It is even the basis for the new industrial transformation, namely Industry 4.0, and is…
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…
The working principle and application scenarios of 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.…
Does gprs dtu require a card?
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…
LoRa network architecture
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…
