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working group, revealed the latest clear incident of China Unicom’s 2G network withdrawal. 2G will be completely withdrawn

5G (fifth generation network) is under development. Promising to deliver blazing-fast speeds and eliminate congestion, the technology promises to revolutionize mobile networks and create new economic opportunities: but, how will it do this? How will it differ from 4G? The much-anticipated fifth generation of mobile

The proliferation and popularity of IoT devices has led to the rise of low-power, wide-area network (LP-WAN) options such as SigFox, LoRa, and Weightless. Traditional cellular options, such as 4G and LTE networks, consume too much power. Furthermore, they are not suitable for applications where

In an era when RS232 ports were common, it was by far the most common method of bit-by-bit communication, so much so that the term “serial port” became synonymous with “RS232 port.” Using the word “serial” in conjunction adds to the confusion. Note that USB

On March 11, 2021, the 3rd Internet of Things Industry Innovation and Development Conference (Chengdu, China) and the 2020 Internet of Things Industry Annual Conference were held in Jingronghui, Chengdu. The theme of this conference was “Integrated Innovation Intelligent Internet of Things “. Zongheng Intelligent

There are many ways to implement the physical layer. Network equipment offers a wide range of connectivity options. Certain networks are well defined using the OSI model, where cables, bridges, industrial routers, serial servers, DTUs, and PCs can be easily identified. Sometimes there are just

On the afternoon of March 11, 2021, the 3rd Internet of Things Industry Innovation and Development Conference (Chengdu, China) and the 2020 Internet of Things Industry Annual Conference were successfully held in the large conference room on the 1st floor of Building 7, Jingronghui ,

“The four main parts of any IIoT system are smart assets, data communications infrastructure, analytics and applications to interpret the data and act on it, and people. Smart assets include machines or other assets with sensors, processors, memory, and communications capabilities. In some cases, these

Q: What can the industrial router wireless client function achieve? The wireless client function of the industrial router can realize Wi-Fi bridging, which can be understood as a small relay function, but it is not completely equivalent to a relay. For example, in an external

In industrial networking control, power conditioning, and point-to-point communication applications between computers, data is sent on the serial communication bus for various types of physical networks, such as RS232, RS485, and controller area networks. Each interconnected system typically has its own power supply, and systems

As we all know, the serial port server is a data communication device that converts the serial port into a TPC/IP network interface. So what is TCP/IP? Although TCP/IP communication (and collecting data from TCP/IP devices) may seem intimidating at first glance, it is actually

Since the advent of the USB interface, the number of serial ports installed on serial devices and computer hosts has decreased, but serial interfaces are still widely used in industrial networking environments or commercial projects. There are dozens of serial data interfaces in use today.
