Gateways, routers, and switches are also devices that connect to the network, but they have different functions and uses. First, let’s understand what gateways, routers, and switches are. gateway Simply put, a gateway is a device that connects two networks. Many LANs now use routers

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 radio frequency system, the design

Crystal oscillator is a crystal oscillator. It mainly provides a highly stable time frequency signal for the circuit so that electronic components can work uniformly. How is this achieved? 1. Working principle of crystal oscillator It turns out that the traditional LC oscillator has poor

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 lists that GFSK can be

The layout of components in PCB design is crucial. A correct and reasonable layout not only makes the layout more tidy and beautiful, but also affects the length and quantity of printed wires. A good PCB component layout is extremely important for improving the performance

WiFi6 is a naming convention proposed by the WiFi Alliance for wireless network standards. It changed 802.11ax to WiFi6 and was released in 2019. The routers currently on the market are all 802.11ac, which is WiFi5, which was released by the WiFi Alliance in 2014.

The so-called driver actually refers to the power supply of LED lamps. From a professional perspective, it can be divided into 4 types: namely “resistance-capacitance type, constant voltage type, constant current type and constant current and constant voltage type”. The following is a brief introduction

The Internet of Things is an important product and symbol of the information age. Its emergence not only promotes the rapid development of the Industrial Internet of Things, but also has a huge impact on military construction and combat methods, and is closely related to

With the development of society, the term “smart home” has become full of our lives, marking the advent of the Internet of Things era. The Internet of Things (IoT, Internet of things), that is, the “Internet where everything is connected”, actually uses information and communication

In recent years, the manufacturing industry has gradually become one of the most active users of the Internet of Things. This technology brings digital innovation to the production floor, allowing manufacturers to increase efficiency, deliver higher quality products, and optimize resource management. Now, the Internet

1. Agricultural greenhouse automation is compared with traditional agriculture, especially traditional large-scale agriculture. The development of traditional large-scale agriculture is slow due to various factors. Maintaining normal agricultural production consumes a lot of labor costs, the efficiency is not high, and it is difficult to

The IoT industry is no stranger to FSK and LoRa wireless communications. They are the most widely used IoT technologies. The word LoRa is taken from the first letters Lo and Ra of the two English words Long Range, which means “far distance”. LoRa is
