(1) Flexible structure
Regardless of the environmental limitations, the network can be built when there is electricity, and the number of access ports can be flexibly expanded, so that the resource utilization rate is high, and it is comparable to WLAN in terms of mobility.
(2) High transmission quality, fast speed and stable bandwidth
You can watch DVD movies smoothly online, and the 14Mbps bandwidth it provides is guaranteed for many application platforms. The latest powerline standard, HomePlug AV, has reached 200Mbps transmission speeds; To ensure QoS, HomePlug AV uses a combination of Time Division Multiple Access (TDMA) and Carrier Listen Multiple Access (CSMA) protocols with collision detection to deliver streaming media well.
(3) Wide range
The ubiquitous network of power lines is also an advantage of this technology. Although the wireless network can not break the wall, for high-rise buildings, it is necessary to deploy more than N APs to meet the requirements, and the existence of signal blind spots cannot be avoided. The power line is the most basic network, and its scale is unmatched by any other network. As a result, operators can easily penetrate this network access service wherever there are power lines. Once this technology fully enters the commercialization stage, it will bring great development space to the popularization of the Internet. The end user only needs to plug in the power modem, and it can realize Internet access, TV channel reception programs, phone calls or video phones.
(4) Low cost
Leverage the existing low-voltage distribution network infrastructure without any cabling and save resources. There is no need to dig trenches and holes through walls, which avoids damage to buildings, utilities, and home decoration, and also saves manpower. Compared with traditional networking technology, PLC has lower cost, shorter construction period, and stronger scalability and manageability. At present, the monthly usage fee of the places that have opened the electricity broadband Internet access in China is generally about 50-80 yuan/month, which is the same as the ADSL monthly subscription in many places.
(5) Wide range of applications
As an access technology that uses power line networking, PLC provides the "last mile" solution of broadband network, which is widely used in residential areas, hotels, office areas, monitoring and security and other fields. It is the use of power lines as a communication carrier, so that PLC has great convenience, as long as there is a power socket in any place in the room, without dialing, you can immediately enjoy 4.5-45Mbps high-speed network access, to browse the web, make calls, and watch online movies, so as to achieve a set of data, voice, video, and electricity in one of the "four networks in one".
PLC Development Trends PLC is an electronic device specially designed for digital operation in industrial environments. It uses programmable memory to store instructions for performing operations such as logical operations, sequential operations, timing, counting and arithmetic operations, and can control various types of machinery or production processes through digital or analog inputs and outputs. PLC has been widely used in steel, petroleum, chemical, electric power, building materials, machinery manufacturing, automobiles, textile, transportation, environmental protection and culture and entertainment and other industries, it has high reliability, strong anti-interference ability, powerful, flexible, easy to learn and use, small size, light weight, cheap characteristics.
