Many people can’t tell the difference between LoRaWAN and LoRa. LoRaWAN refers to the MAC layer networking protocol, while LoRa is a physical layer protocol. Although most existing LoRaWAN networks use LoRa as the physical layer, the LoRaWAN protocol also…

An antenna is an energy converter that converts guided waves propagating on a transmission line into electromagnetic waves propagating in an unbounded medium, or vice versa. Regarding the design of a low-power, short-range 2.4GHz wireless transceiver device used in a…

Hardware appears in many forms in the IoT, whether it’s the underlying processors that power devices, sensors that collect information from the physical world, or edge computers that collect and analyze data. Various hardware including gateways, radios, and chipsets play…

The Internet of Things (IoT), a network of connected “smart” devices that communicate seamlessly over the Internet, is changing the way we live and work. On farms, wireless IoT sensors can transmit information about soil moisture and nutrients to agricultural…

The Internet of Things involves extending internet connectivity to anything from standard devices like traditional desktops, laptops, smartphones and tablets to connecting physical devices and everyday objects that are not internet-enabled. These devices are embedded with program technology, can communicate…

From the current point of view, Shanghai is the first city in China to fully offline narrowband dial-up Internet access. This may also mean that the already pitiful narrowband dial-up Internet service will become a thing of the past: a…

The Internet of Things connects things through the network. The currently developed and mature wireless access networks have the characteristics of large capacity and flexibility, can provide faster data transmission rates, and support a wide variety of applications. Currently, GSM…

One of the protections in industrial routers is often referred to as “anti-surge (EMC)”. There are many reasons for a surge. A surge is a spike pulse with a high rising speed and short duration. Grid overvoltage, switch ignition, reverse…

Finished IoT machines should have built-in smart manufacturing capabilities, especially machines with advanced features such as motion control. Even if factories are not currently connected to the Industrial Internet of Things (IIoT), you can be sure that they will be…

The growth of the Internet of Things (IoT) has dramatically changed the way consumers interact with their cars, homes, and appliances, but the aptly named second digital revolution is also having a major impact on the industry. From machine learning,…

We are always connected to the internet. We do this with our phones, tablets, laptops, gaming systems, and cars. While some of these use wires and others use proprietary communication methods (albeit wireless), we will focus on Wi-Fi and Wi-Fi…

What is an industrial switch A switch can be understood as an intelligent, high-performance hub. Industrial switches are devices that implement wiring functions in industrial scenarios and can adapt to harsh environments. As data is sent back and forth through…
