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 are battery consumption. Similar to

What is a serial to ethernet device used for? The main purpose of this tool is to provide communication between serial devices and computers through its COM port, which recognizes the signals sent by the serial port over Ethernet. In practice, this means that using

Starting from the analysis of NB-IoT Internet of Things technology, it introduces the physical layer of the NB-IoT system and its coexistence with other systems, introduces the LTE system and GSM system, and analyzes the necessity of research on their impact on the NB-IoT Internet

LoRa Alliance There is a movement to standardize LoRa’s MAC functionality, called the LoRa Alliance. The LoRa Alliance developed the LoRaWAN protocol for use by mobile network operators that use unlicensed spectrum to communicate with IoT devices in their networks. LoRaWAN is ideally suited for

In order to make the transmission of networking equipment such as industrial routers, DTUs, and serial servers more stable, these devices will be equipped with anti-surge, anti-static, anti-pulse and watchdog protection. Among these hardware protections, there is one that can keep the internal processes of

What is a 4g industrial router? 4G industrial router is an IoT communication and networking device that provides fast networking solutions for user equipment through the 4G LTE cellular network. Usually 4g industrial routers use high-performance embedded CPUs with operating frequencies as high as 580MHz

Serial server transparent transmission principle The serial port server is a small electronic device that performs two-way transmission between TCP/IP data and serial port data. Its working principle is that when the serial port server is connected to the computer, it will create a virtual

1. Global System for Mobile Communications (GSM): This is a mobile network widely used by mobile phone users worldwide. In this case, the customer’s information is placed on a SIM card that can be carried in the new phone. It operates on the 900 MHz

As the industry develops rapidly, the number of devices required for data management and reception is also increasing. In order to solve the problem of communication between numerous devices and the problem of combination of devices in a single network, the concept of Internet of

Engineers often find themselves with insufficient cable length to connect end devices with RS232, RS422 and RS485 interfaces to their computers or controllers. How to solve this problem? There are many ways to expand the RS232, RS422 and RS485 interface to solve this problem. Before

Traditional 4G wireless networks offer more capabilities than these use cases require. Additionally, IIoT applications require seamless coverage in remote environments, where staying connected consumes battery power and shortens device life. With the advent of 5G and NB-IoT, the ratio of cellular to non-cellular connections

Cellular networks are changing and some are dying. At the recent 11th Global Mobile Broadband Forum (MBBF), Miao Shouye, leader of China Unicom’s 5G co-construction and sharing working group, revealed the latest clear incident of China Unicom’s 2G network withdrawal. 2G will be completely withdrawn
