With the continuous improvement of industrial automation, the frequency converter has been widely used. In simple terms, the frequency converter is the application of frequency conversion technology and microelectronics technology, by changing the frequency of the motor power supply to control the power control equipment of the AC motor. The frequency converter is mainly composed of rectification, filtering, inverter, brake unit, drive unit, and detection unit micro-processing unit. The inverter also has many protection functions, such as over-current, over-voltage, overload protection and so on. It has been more than 30 years of R&D and application of science and technology since the manufacture of the first inverter in our country. With the increase in the level of electronic technology and the needs of the market, there are more and more kinds of frequency converters and more and more functions. perfect. Various inverter manufacturers have launched double competition in price and quality. In this competitive atmosphere, what kind of development track will the inverter enter? What kind of new situation will the industry develop?
The general purpose of the inverter is to adjust the speed, and reduce the starting current to save energy and reduce consumption. The different operating voltages of the equipment have different requirements for the inverter. At present, the frequency converter on the market is roughly divided into three types: high, medium and low voltage. No matter which kind of inverter, the manufacturers are all heading towards the same goal, that is, high performance, multi-function, and small size. This is also the demand of inverter users. Therefore, the manufacturers of inverters will The development and production of their respective inverters have brought new requirements.
For the inverter, the performance of the inverter mainly depends on three aspects. The first is the effect of the output voltage harmonic on the motor, the second is the harmonic pollution and input power generated by the power grid, and the third is See how the energy consumption of the inverter itself. The basis for judging these points is that not only must the inverter be intelligent and modularized, but it must also reduce the losses caused by the use of the inverter and the switching process of the equipment. These aspects have not only become the main embodiment of determining the quality of inverters, but also the priority for inverter manufacturers to continuously develop and improve.
Nowadays, the functional requirements of the society for products are getting higher and higher, and a single application field can no longer meet the needs of a wide range of users. Therefore, in order to meet the challenges brought about by different application fields, inverters need not only continuous upgrading, but also need Maximize the diversification of products to meet the needs of different application areas. The fields in which inverters are now applied include various industrial productions, urban water supply systems, and household appliances. In these fields, not only the performance of the inverter is required to be stable, but also products with full digital, systematic, and networked functions are needed. The R&D and production of such products not only represents the progress of frequency conversion technology, but also brings more for production and life. The cheaper, more industry to promote further development.
The inverter industry has been unprecedentedly developed and applied in modernization such as cement, elevators, printing, and electricity, as well as medicine, communications, transportation, transportation, electric power, electronics, and environmental protection. Almost all industries in the national economy are inseparable from inverters. As a whole, the competition in China's inverter industry is increasingly fierce.
The various information technology innovations and fierce competition in the market have brought about considerable development momentum and space for the inverter industry. A new round of inverter innovation will intensify, and the inverter market will enter a period of rapid growth.
What is 5G CPE?
5G CPE is a kind of 5G terminal equipment. It takes 5G signals from a carrier's base station and converts them into WiFi or wired signals, allowing more local devices (phones, tablets, computers) to access the Internet. It can be seen that 5G CPE is similar to the function of the "optical network unit" for home fiber broadband access.
What is a WiFi router?
WiFi routers are also known as wireless routers or access points.
A WiFi router acts as a Wi-Fi transmitter. It connects directly to a modem, router or switch via cable. This allows it to receive information from the Internet and transmit information to the Internet. Phones, tablets, laptops and other devices can pick up its Wi-Fi signal and then connect to the Internet.
What is the difference between 5G CPE and WiFi router?
The 5G CPE is actually a combination of a 5G modem and a WiFi router. With an independent 5G CPE, the device can access the Internet directly through the WiFi signal or the LAN port of the CPE. Of course, the 5G SIM card needs to be inserted into the SIM card slot of the CPE. However, a WiFi router will not be able to provide Internet access without connecting to a modem or router via cable.
To provide users with greater flexibility and reliability, many 5G CPE routers not only support 5G networks and 4G LTE networks, but also come equipped with WAN Ethernet ports for surfing the Internet. For local networks, WiFi 6, WiFi 5, and LAN ports are usually supported. Some models, such as the Hocell 5G CPE M111, are also equipped with telephone ports for VoLTE/ VoNR voice services.
What are the advantages of 5G CPE over ONU?
ONU is a kind of CPE, and the difference between ONU and 5G CPE is that the former connects to optical fiber access network equipment, while 5G CPE connects to 5G base stations.
There is also a question, since there is an ONU, why do you still need 5G CPE, and will 5G CPE replace ONU?
Let's start with the conclusion, of course not.
The current 5G CPE products all use the same or similar 5G chips as 5G mobile phones, have strong 5G connectivity, support SA/NSA networking, and are compatible with 4G/5G signals. In terms of speed, 5G CPE is similar to ONU.
The advantages of 5G CPE
1. Mobility and
Unlike traditional ONUs, which can only be used in fixed locations, 5G CPE can be "mobile." Where there is a 5G signal, 5G CPE can be used.
For example, when we go on a family vacation to a suburban estate, we can use 5G CPE to set up a Wi-Fi 6 high-speed hotspot that allows all family members to go online and share videos on social networks.
Another example is when a company is away at a trade show, it can use 5G CPE to provide Internet access to visitors and employees.
Traditional "fibre broadband" is relatively easy to set up. You go to the sales office and request a package, and then you can open it. But cancelling is tricky. Today's broadband services have a contract period. Before the end of the agreement period, you can not arbitrarily stop it. If you need to move, you have to switch to fiber broadband, which is also very troublesome. As for 5G CPE, as long as you have a 5G mobile phone SIM card, you can get high-speed Internet access.
For young people who are renting, as well as small businesses that need Internet service, 5G CPE is an ideal choice because of its mobility, fast Internet service registration and termination. 5G CPE is also suitable for remote areas or places with difficult terrain where fiber is virtually unavailable. Due to its large area and small population, many parts of the world began to use CPE long ago. They use 5G Outdoor CPE to receive signals from base stations and convert them into raw signals to access the Internet.
5G CPE can be upgraded to small base stations
5G CPE modifies 4G or 5G as a WiFi hotspot. WIFI devices can be converted via 5G CPE to access 4G or 5G networks.
Further, the WIFI hotspot, including the information processing and transmission within the CPE, is divided into 2 completely separate channels. The internal network channel has its own wi-fi, which is supervised by a person, and also has an account password verification. The external network channel is regulated and managed by the carrier. Two-way verification, remote monitoring, encrypted transmission, vibrant passwords, strict isolation of software and some devices to meet carrier-grade security requirements, complete isolation of indoor and outdoor wi-fi, extrannetwork-channel authentication of customer SIM cards,
5G CPE can be upgraded to a small base station, with both WiFi LAN and micro-base station functions. Good signal at the window, negative signal inside the car. Install a 5G CPE micro-base station by the window of your home and connect it to a power supply (or bring your own power supply).
It can access 4G and 5G networks through the CPE's external network. The phone charges, SMS charges, and information charges generated by the CPE are included in the phone SIM card number, but are not included in the CPE device. Peripheral WIFI devices without SIM cards, computer tablets (generally with WIFI), without wi-fi can get the USB user interface wi-fi card, through the WIFI Intranet access to 4G/5G network, resulting in traffic charges Input number corresponding to the CPE SIM card.
5G CPE micro base station, no matter where you go, as long as there is a 4G/5G signal by the window, there are mobile phones indoors, there are other terminal tools with SIM cards, and WIFI, you can call the Internet standby to solve the problem of indoor invisible. WIFI tools without SIM cards can also pass through the Intranet.
5G CPE applications
1. 5G CPE will act as a smart home gateway
In addition to providing Internet access, 5G CPE will also act as a smart home gateway in the future.
The demand for home routers has been the focus of competition among many vendors, because the router itself brings profits, as it is the gateway to the entire home network service and the entry platform for digital home operations. The 5G CPE serves the same purpose as a router. It will be the intelligent gateway for the unborn 5G family and the fulcrum for the intelligent life of the whole family.
With 5G CPE, users can control a variety of smart devices in their homes and connect everything, significantly enhancing the life experience of family members.
5G CPE has great potential for enterprise demand
In addition to consumer demand, 5G CPE has a very broad operational prospect in terms of enterprise demand.
Take smart factories, for example. In the future, all the devices and gears in the factory will be networked. 5G CPE can act as a unified traffic inlet and outlet for all devices in an area (shop floor), providing low-cost, high-speed network connectivity for these devices.
With the increase of application scenarios, 5G CPE will support more communication protocols other than 5G (such as Bluetooth, UWB, etc.), and truly become the control center of all devices.
3. Pipe network monitoring
Urban heating monitoring, natural gas network wireless monitoring, urban water supply network monitoring.
conclusion
All in all, 5G CPE is very important for both households and businesses.
With the full rollout of 5G network construction, 5G signal coverage is getting farther and farther. The demand for 5G CPE will continue to increase, and there will be more and more application scenarios around 5G CPE.
