PLC is a communication method that uses power line transmission data and voice signals. It has a history of decades of development. On the mid -to -high voltage transmission network, data or voice through the use of lower frequencies (9-490kHz) through the electric wire carrier is one of the main forms of power line communication technology applications. In the low -voltage field, PLC technology is first used in load control, remote metering and home automation. Its transmission rate is generally 200bit/ s or lower, called low -speed PLC.

We can use the HTTP protocol as the transport layer on the RPC protocol, so that RPC requests can use the characteristics of HTTP to implement caching, compression, encryption and other functions.

Edge computing is an emerging computing model that aims to move computing power and storage resources closer to users or data sources. Edge computing greatly reduces the dependence on centralized cloud servers by processing data on edge devices, sensors, and edge nodes. This distributed computing model can provide faster, efficient and secure computing services.

The Ministry of Industry and Information Technology recently announced that the 6GHz frequency band will be launched globally for 5G and 6G systems.

MOSFET (Metal Oxide Semiconductor Field Effect Transistor) is also called Metal Oxide Semiconductor Field Effect Transistor, referred to as MOS tube, which is a kind of field effect transistor. MOSFET has become the most widely used semiconductor device at present, and is widely used in various electronic equipment, including power supplies, computers, TVs, etc.

Lost packet retransmission is a very important function in data communication applications, especially in wireless communication, it is an indicator that determines the advanced level of communication protocols.

Switching power supply is a power supply device for AC and DC conversion. It switches the input voltage into a pulse signal at a high frequency through the switching action of the switching tube, and then converts it into a DC voltage output through a rectification and filtering circuit. Switching power supply has the characteristics of high efficiency, small size, light weight, and good stability.

The Matter protocol is based on open standards and encourages major manufacturers and developers to adopt a unified communication protocol to achieve interoperability between devices.

With the rapid development of the Internet of Things (IoT), finding suitable solutions for reliable and long-distance communication is becoming more and more important. Traditional wireless communication technologies have limitations in coverage and power consumption, and LoRaWAN and LoRa technology have become key tools to address these challenges.
