2024-05-08 Leading Industrial network upgrades: The rise of 5G Red Cap industrial routers Integration and breakthrough of 5G Red Cap technology With the rapid development of 5G technology, the application of the Internet of Things (IoT) has gradually penetrated into all walks of life, bringing great convenience to people's life and work. In this process, 5G RedCap industrial routers, with their unique advantages, have become an important force to promote the development of Internet of Things applications. Next, 5G RedCap industrial routers will be popular science and take you to understand their important role in the field of Internet of Things. 5G RedCap, or 5G Reduced Capability, is a 5G lightweight user terminal type proposed in 3GPP Rel-17. It greatly reduces the cost of 5G chips, modules and terminals by reducing terminal bandwidth, reducing the number of transceiver antennas, and reducing the number of modulation steps. At the same time, RedCap's 5G based system can be combined with 5G slicing, 5G LAN, high-precision timing, URLLC and other 5G enhancement functions on demand to meet the enhancement needs of different fields of 5G industry applications. RedCap is mainly aimed at industrial wireless sensors, video surveillance and wearable devices, and can meet these business needs while significantly reducing the cost of 5G chips, modules and terminals.4G industrial router Features of 5G Red Cap industrial routers High speed: 5G RedCap offers a higher peak data rate than traditional 4G technology, enabling industrial routers to meet applications that require higher data throughput, such as video surveillance or smart grid monitoring.5G Industrial Router Low latency: 5G RedCap technology has lower latency and is capable of supporting applications that require near-real-time data communication, such as industrial aut

2024-04-16 Overview of 6G AI Data Services The background of the emergence of 6G AI data services With the continuous maturity of AI technology and the continuous enrichment of application scenarios, AI applications represented by deep learning have radiated from pan C-end fields such as consumption and the Internet to traditional industries such as manufacturing, security and medical care. The large-scale implementation of AI technology innovation and application has driven the vigorous development of the big data intelligent market, and also injected market vitality into data services. 5G has opened up the scene connection of the Internet of Things, connecting thousands of industries to mobile communication networks, bringing new scenarios and ubiquitous data. One of the functions of 6G networks is to empower AI capabilities to applications and scenarios in various fields based on ubiquitous big data, creating an "intelligent ubiquitous" world through wide area coverage and intelligent adaptation to scenarios. Therefore, 6G networks require the construction of endogenous, ubiquitous, and distributed AI capabilities [1]. In the 6G network, endogenous intelligence can utilize AI algorithms internally to improve network performance, enhance user experience and efficiency, and provide various support capabilities for AI externally, making AI training/inference more efficient and real-time. It can extract and encapsulate network intelligence, serving customers in different industries. There will be a wide variety of AI model data and training data in the new 6G system, which need to be able to interact and share among various network element nodes in different network architectures. With the commercialization of the AI industry, the demand for more forward-looking dataset products and highly customized data services will become mainstream.

2024-04-08 6G AI Data Service Framework and Enabling Technologies Perception and intelligence will be the two major endogenous capabilities of 6G networks. The former generates massive amounts of data, while the latter makes automatic decisions based on data to improve network performance or provide services to upper level applications. 6G endogenous intelligence can utilize artificial intelligence (AI) algorithms to improve network performance, enhance user experience and efficiency, while leveraging ubiquitous computing power and data to provide multiple support capabilities for AI, achieving efficient AI training/inference, extraction and encapsulation of network intelligence, and serving different industries and applications. The existing mobile communication network uses user side session as the "pipeline" for data transmission, integrating single point technology to achieve data processing, data supervision, and security privacy protection, providing specific data service capabilities for intelligent applications. However, it lacks a normalized data service framework and faces many challenges in data governance. In the 6G era where computing power and data are ubiquitous, new perception and intelligence, as well as their enabled intelligent applications, will bring new types of data. Moreover, the value inherent in the data itself needs to be explored and provided to data consumers both inside and outside the network in the form of services. This white paper is based on the characteristics of 6G endogenous intelligence and perception, as well as distributed computing power and data. It proposes a data carrying mechanism, data orchestration, and service architecture design independent of traditional user interfaces. It introduces a 6G data carrying mechanism with on-demand processing and arbitrary topology support, describes the functional architecture and key enabling technologies of the data interface, and finally presents typical application scenarios of data services.

2024-04-01 What technology is RedCap mentioned in 3GPP R17? RedCap (Reduced Capability) refers to the ability to reduce. It is a new technology standard protocol specially launched by 3GPP in the 5G R17 stage for 5G application scenarios with low speed and latency requirements. It aims to comprehensively improve the quality and coverage of 5G networks, and can also be understood as "lightweight 5G". 5G is divided into three major application scenarios: eMBB (Enhanced Mobile Broadband), uRLLC (Low latency and high reliability communication), and mMTC (Massive Internet of Things communication). EMBB is an upgrade of 4G MBB (Mobile Broadband), mainly focusing on network speed, bandwidth capacity, spectrum efficiency and other indicators. While uRLLC focuses on reliability and delay, mMTC focuses on the number of connections and energy consumption, and both serve the industrial Internet, including industrial manufacturing, Internet of Vehicles, remote meter reading and other vertical industries. However, different application scenarios in the Internet of Things require different network capabilities. For example, in terms of speed, VR/AR and high-definition broadcasting require high-speed connections; Remote meter reading and sharing devices only need to synchronize data, which can be achieved at low speeds. In addition to speed, there are many application scenarios that are more concerned about power consumption and cost. The complete version of 5G terminal chips and modules has extremely complex designs, extremely high research and development barriers, and huge investment costs. The high price has also affected the landing of 5G in the vertical industry. So, 5G needs to establish a lightweight version to meet the application scenarios of medium and medium high speed requirements, reduce the deployment and usage cos

2024-03-18 Huawei releases its first star flash kit, showcasing the industry's first star flash keyboard simultaneously On December 26th, Huawei held a press conference on the Wenjie M9 and Huawei's winter full scenario. At the meeting, Huawei MatePad Pro 13.2-inch Collector's Edition, Huawei MatePad Pro 13.2-inch Star Flash Package, and Huawei MatePad Pro 11-inch Star Flash Package were showcased in turn. Finally, the emergence of Huawei Smart Magnetic Keyboard (Star Flash Edition) announced that Huawei tablets were the first to complete the closed loop of the Star Flash ecosystem in professional creation and mobile office settings. In my opinion, this is a small step for Huawei, but it is a big step in the era of Starflash. We are very much looking forward to more Starflash products being launched in the future. The Huawei tablet flash product released this time. In my opinion, the most noteworthy among them is the Huawei MatePad Pro 13.2-inch Collector's Edition. It is understood that this version includes four products and peripherals that support star flash connection, including the MatePad Pro 13.2-inch tablet, the industry's first star flash keyboard Huawei Smart Magnetic Keyboard (Star Flash Edition), HUAWEI M-Pencil (third-generation) stylus, and Freebuds Pro 3 earphones. Among them, the Huawei MatePad Pro 13.2-inch is currently the largest Huawei flagship tablet in terms of screen size. In addition to having an ultra-high screen to body ratio of 94%, the body weight is also extremely light and thin, weighing 580g but with a thickness of only 5.5mm. With the support of star flash devices such as the HUAWEI M-Pencil (third-generation) stylus and Huawei Smart Magnetic Keyboard (star flash version), its usability is no less than that of some lightweight laptops, making it a versatile office product. The newly released Huawei Smart Magnetic Keyboard (Star Flash Edition

2024-02-19 What is the difference between portable Wi Fi and routers? The portable WiFi can be plugged into a 4G card, which is actually a mobile hotspot that distributes mobile data signals. Of course, because it uses 4G network, you can take it everywhere and provide network for your phone and tablet wherever you go. But the shortcomings are: Firstly, its network latency is generally higher than routers because it distributes 4G of data. The latency of 4G is originally slightly higher than that of routers, and in addition, during the forwarding process, the portable WiFi needs to process data, so the latency is even higher. Secondly, the speed is slower. Currently, the 4G network speed is around 1-2M per second, but routers can generally reach speeds of over 10M. Thirdly, it uses traffic. If we all use it to access the internet, we will have to pay a relatively high amount of traffic every month. Even with a 4G network card, it is slightly more expensive than broadband fees. The router is connected to a fixed network cable, and the disadvantage of mobile WiFi is its advantage. There is no limit to traffic, faster, more stable, and lower latency. At the same time, it can only be fixed in one place, not flexible, and generally can only be placed at home. It is recommended to install broadband and configure routers for those who frequently need to access the internet; For long-term business trips, mobile WiFi can be considered.

2024-01-29 What determines the router's ability to penetrate walls? WiFi wireless network is believed to be necessary in most families. WiFi is connected and used immediately, which is very convenient. However, due to the lack of awesome in router equipment and other reasons, the use of WiFi network is not as good as ever, and problems such as poor signal and network disconnection often occur. A more common phenomenon is that the router placed in the bedroom separated by a few walls in the living room cannot receive WiFi signals. It can be seen that the wall penetration ability of most routers is still quite poor nowadays. So why is the ability of routers to penetrate walls generally weak? Today, the author will give you a science popularization. The first point is the issue of transmission power. The higher the wireless transmission power of a router, the better its ability to penetrate walls. However, an important point is that if the transmission power of a wireless router exceeds 100mW, the electromagnetic radiation it releases may cause harm to the human body. Therefore, the country also stipulates that the transmission power of wireless routing products cannot exceed this value. Therefore, in the current market, The difference in transmission power values between routers is not significant, so when choosing a router, there is almost no need to consider this difference. There is a problem with the frequency of WiFi signals. The 2.4G frequency band is still the mainstream frequency band for various routing devices. Compared with the 5G frequency band, the 2.4G frequency band has a stronger ability to penetrate walls, but at the same time, the 5G frequency band also has the advantage of faster speed and less interference. Due to the interference signals generated by various appliances such as microwaves at home being in the 2.4G frequency band, if the router can only support the 2.4G frequency band, it is easily affected by the appliances. If the router can support both frequency bands at the same

2024-01-22 The principle of Mesh, as well as its functions, advantages, etc What is the difference between Mesh and Relay as they both expand signal coverage? When many people choose routers, an important indicator of concern is whether the signal is good or not, and whether it can cover every corner of their home. In fact, for large or multi story buildings, a router is usually not enough. 5G signals are weak through walls, making it difficult to ensure good quality in every corner of the house. Before the emergence and popularization of Mesh technology, we mainly used wireless relay to expand signal coverage. Compared to wireless relays, Mesh completely compensates for the shortcomings of the latter and can be said to be the most ideal solution at present. Mesh system configuration is simpler The Mesh system is a whole, and adding Mesh nodes and modifying Mesh network settings are often simple. Modifying the information of the master node will automatically synchronize other routers in the entire Mesh network. Adding a new node also requires setting SSID, password, superior router, and other information, which will be automatically synchronized and networked. With just one click, you can easily complete the network configuration, which parents and children can use. However, line relays require configuring SSIDs and passwords one by one, and selecting the network that needs to be relayed is extremely cumbersome and has a high threshold. Mesh system can intelligently group, I fix it The Mesh system will dynamically construct the optimal network environment based on the number of nodes and network conditions. According to the layout and placement of the house, it can form a star shaped, chain shaped, or chrysanthemum shaped network, so that the equipment in the network can have excellent signal coverage and speed at any position. Even if one of the nodes fails, the Mesh network will rebuild the optimal network environment.

2024-01-15 Differences between 2.4G and 5G router signals I believe everyone still remembers the 2.4G and 5G signal channels mentioned earlier when we talked about how to strengthen WiFi signals. Many friends are actually very confused about their concepts. Today, I will share with you the knowledge points of 2.4G and 5G signal channels. 1. What are 2.4G and 5G Nowadays, most routers are dual band routers, which means that one router can set up two wireless networks. The default one is in the 2.4G frequency band, and the other is in 5GHz. They are all frequency bands of radio waves, and everyone should be familiar with the characteristics of radio waves, that is, the lower the frequency, the less attenuation in the propagation process, and the wider the coverage range. 2. The difference between 2.4G and 5G 1. Why do we usually choose to use 2.4G signals? Because at the same distance as the router, 5G signals are significantly weaker than 2.4G signals. According to the physical characteristics of electromagnetic waves, the longer the wavelength, the less attenuation, and it is easier to propagate around obstacles. However, 5G signals have high frequency and long wavelength, while 2.4G signals have low frequency and long wavelength. Therefore, although 5G signals have better wall penetrating ability than 2.4G signals, the signal after passing through is much weaker. 2. Will weak 5G signal affect network speed? It depends on the situation, network speed is not only related to signal strength, but also to the quality of the channel. After passing through obstacles, there may be a 3-bar signal in the 2.4G frequency band, but only a 2-bar signal in the 5G frequency band. If there is too much surrounding interference, the 2.4G fre

2024-01-08 The difference between wifi 7 and wifi 6 Wi Fi 6 (formerly known as IEEE 802.11. ax), also known as the sixth generation wireless network technology, has been established and promoted by the Wi Fi Alliance for over 4 years since 2019. According to the previous 5-6 year update rhythm of the Wi Fi Alliance, Wi Fi 6 has also reached a time when it needs to be updated and replaced. According to data from the Wi Fi Alliance, the demand for wireless bandwidth in the next generation of 360 degree AR/VR applications has reached up to 200Mbps, indicating that the current Wi Fi speed has gradually reached a bottleneck for the new generation of entertainment devices, and now it is time for faster, more stable, and lower latency network connections to provide a better user experience. Moreover, research reports from 2000 gamers in the UK and the US also showed that up to 97% of gamers have experienced latency issues, further emphasizing the importance of low latency for wireless connectivity. Wifi 6 Outdoor Wireless Ap Based on the above situation, the Wi Fi Alliance has launched a new generation of IEEE 802.11be standard, Wi Fi 7, to meet higher network connectivity requirements. According to the Wi Fi Alliance, Wi Fi 7 will further enhance the functionality and performance of Wi Fi networks, including higher data transfer rates, lower latency, and better network coverage. These improvements will help drive the development of AR/VR, gaming, and other high bandwidth applications, and provide a better user experience. So, what are the upgrades to the previous generation standards for Wi Fi 7, which will be fully promoted in 2024? Wifi 6 Wireless Router Firstly, the maximum transmission speed of Wi Fi 7 can reach 46Gbps (domestic 30Gbps), which is close to five times that of Wi Fi 6.

2023-12-26 Introduction to Mobile Intelligent Networking Intelligent devices capture faces and automatically connect to the internet for remote analysis and judgment; Smart agricultural machinery and tools, utilizing gigabit networks to achieve increased production and income of agricultural products; Past medical history and health records are synchronized to the medical expert team through high-quality networks With the high-quality development of the information and communication industry, the internet not only provides "hard" support for the development of the digital economy, but also allows more people to enjoy high-speed online life. In recent years, diverse forms of digital technology applications have penetrated into all aspects of social production and public life, promoting the development of new industries and ecosystems, while also raising higher requirements for people's daily internet needs. In order to meet the growing needs of the people for a better life and solve the contradiction between the rapid development of digital technology and insufficient daily network supply, China Mobile Smart Home Operation Center launched a pilot project for mobile intelligent networking technology in 2022, achieving a breakthrough from 0 to 1. So, what exactly is mobile intelligent networking, and what convenient experiences does mobile intelligent networking bring to users? Next, let's popularize science. What is mobile intelligent networking? I believe many friends believe that mobile intelligent networking is a name for a network. In fact, mobile intelligent networking is a collection of one-stop network services provided to users based on routers. It can segment scenarios according to users' daily network needs and provide different value-added services for different scenarios. It is applied in various scenarios such as network security, child and elderly protection, network optimization, game acceleration, and education acceleration.

2023-12-18 What is the difference between 40MHz and 20MHz routers 40MHz and 20MHz are both wireless signal bandwidth in current wireless local area network technology. In theory, 40MHz has twice the channel bandwidth and twice the theoretical data transmission rate compared to 20MHz. However, in practical applications, setting a higher bandwidth has a greater chance of conflicting with surrounding WiFi signals, which will affect the actual data transmission rate. Wireless Router The difference between 20MHz and 40MHz can be imagined as the width of the road. The wider the width, the more data it can run, which in turn increases the speed. But the "road" of wireless networks is shared by everyone. As you occupy a wider road and run more data, it is more likely to collide with others. Once you collide, everyone will slow down, even slower than walking on narrow roads. Originally, squeezing at 20MHz could allow 4 people to use it at the same time, but if you use 40MHz, you can only use it for 2 people at the same time. 5G Industrial Router So the question of which one is better is not related to the size of your house, but most importantly, how many people are walking with you nearby. Using scanning software can easily see the occupancy of the surrounding frequency bands. So, Beijing Broadband Connect suggests that if there aren't many people nearby using it, congratulations, use 40MHz to enjoy high-speed! If there are many vehicles around, it is best to find a lane with fewer vehicles and use 20MHz instead. Wifi 5 Ceiling Wireless Ap

2023-12-11 Do I have to buy a router that supports MU-MIMO In the past two years, MU-MIMO has been one of the highlights of promotion by manufacturers in the high-end router field. With the halo of new technologies such as 802.11ac Wave2, MU-MIMO, and WiFi6, routers are becoming increasingly expensive. In most cases, due to limited conditions, users will not quantify the actual effectiveness of these technologies, and whether routers that support MU-MIMO technology that are purchased at a high price are worth it has become a question in the minds of some users. To understand MU-MIMO, the first step is to understand MIMO. To explain the concept of MIMO, let's first understand what SISO is. SISO SISO stands for single input and single output, which is easy to understand. In the field of wireless routers, it can be simply explained as using one antenna for both sending and receiving. On the basis of SISO, SIMO and MISO technologies have been developed, representing single in multiple out and multiple in single out, respectively. MIMO MIMO means multiple inputs and multiple outputs, referring to the situation where a message is transmitted by multiple antennas at the transmitting end and received by multiple antennas at the receiving end. It utilizes multiple antennas at the transmitting end to independently transmit signals, while using multiple antennas at the receiving end to receive and recover the original information, achieving higher transmission rates at a lower cost. MIMO technology can be traced back to 1908 when the famous Italian radio engineer Marconi proposed using it to resist fading. In the 1970s, it was proposed to use multiple input and multiple output technology in communication systems, but the groundbreaking work that greatly promoted the use of multiple in

2023-12-04 The signal of the built-in antenna may not be weaker than that of the external antenna! At present, most routers on the market adopt the design of external antennas, from the initial one antenna to eight antennas or even more. With the development of technology, hidden antennas are gradually becoming popular, and wireless routers are gradually "removing" antennas. But many users have this concern when choosing routers with built-in antennas - will the signal of routers with built-in antennas penetrate walls weaker than those with external antennas? Judging signal quality solely based on whether the antenna is external or internal is one-sided. In recent years, many testing studies have shown that in the same environment and level of routers, the routing signal strength of the internal antenna is not inferior to that of the external antenna, and it is also aesthetically pleasing and saves space. 4G CAT6 CPE In fact, regarding whether the built-in antenna will affect the signal, we can refer to mobile phones. In the past, the antenna of mobile phones (big phones) was also external, but now the antenna is "nowhere to be seen". However, it is obvious that the built-in antenna does not affect our daily signal reception and phone calls. In addition to mobile phones, televisions are also an example. From the current trend, built-in antennas will gradually replace external antennas as the mainstream. Whether the antennas are external or internal, they are just a solution for wireless router antenna design, regardless of signal strength. Therefore, when choosing a router, you can boldly choose a more aesthetically pleasing hidden antenna router. 4G Cat4 Cpe Tengda MW3 adopts Mesh technology

2023-11-28 Why do routers have multiple antennas? There are several antennas on the router head and a line connection at the back, why does it have so many antennas? Do you still remember the era without smartphones in the past? When mobile communication was not yet popular, routers looked like this: Yes, it doesn't have an antenna. Although it may seem a bit ugly, at least it is a product of the new era. In that era, smartphones were not yet widespread, and WiFi was still stuck at 11b/g and 11a. Its transmission rate was not only theoretically lower than that of wired networks at 100M, but also slightly lower due to environmental limitations. So, wireless routing was not popular in that era until the beginning of large-scale smartphone applications. Early wireless routers were usually single antenna routers, even if there were two antennas, one was usually responsible for 2.4G and the other for 5.8G. With the rapid popularity of smartphones, entertainment multimedia applications such as watching videos, playing games, and listening to music require massive data traffic to support. Due to the incomplete development of early cellular networks, slow transmission rates, and particularly expensive data tariffs, WiFi has made significant progress. 5G Industrial Router The emergence of 802.11n made the theoretical transmission rate of wireless local area networks exceed that of ordinary wired networks for the first time (at that time, wired networks usually had a speed of 100Mbps, except for fiber optics) This depends on the fact that 11n adopts multi antenna technology, also known as MIMO technology. Wifi 5 Ceiling Wireless Ap

In recent years, the rich and diverse forms of digital technology applications have penetrated into all aspects of social production and public life, and colleagues who promote the development of new industries and ecosystems have also raised higher demands for people's daily internet use. Wifi 5 Ceiling Wireless Ap In order to meet the growing needs of the people for a better life and solve the contradiction between the rapid development of digital technology and insufficient daily network supply, China Mobile Smart Home Operation Center launched a pilot project for mobile intelligent networking technology in 2022, achieving breakthroughs from 0 to 1. So, what exactly is mobile intelligent networking, and what convenient experiences does mobile intelligent networking bring to users? Next, let's take a look at science popularization. 5G Industrial Router What is mobile intelligent networking? I believe man

2023-11-13 The three major pain points of routers have been in vain for so many years! With the complete integration of wireless networks into our lives, "Zhilian Interconnection" products are becoming popular, and the most noteworthy thing is the router devices that have entered countless households. It is understood that the penetration rate of routers in China reached over 70% in 2017, and wireless routers reached 50%. Relevant departments have stated that they will strive to achieve broadband coverage of 98% in administrative villages by 2020, gradually achieving wireless broadband coverage. 5G CPE However, the widespread adoption of traditional routers cannot ignore issues such as multiple blind spots, unstable network transmission, easy disconnection, complex device configuration, and lack of security. Based on the situation of the Chinese wireless router market released by the Zhongguancun Online ZDC Research Center, we can see that network speed, network signal, and machine heat dissipation are still the "pain points" that the router market needs to pay attention to. The focus and consumption trends of consumers when choosing wireless routers constantly affect the progress of the router market. WiFi 5 wireless router The basic requirement of a home router is "stability". How can it maintain stable operation during network usage, or can it provide timely solutions when problems arise? Can so-called "smart" routers make internet access more convenient? I believe that most users are still confused, and the top priority in the development of the routing field still needs to be comprehensive innovation around the "pain points" of the hardware itself. WiFi 6 wireless router Pain point 1: Slow internet speed! Undoubtedly, 'slow internet speed' is one of the pain points that consumers often complain about. The poor performance of routers, even

2023-11-06 The functional differences between switches and routers Computer networks are interconnected by different types of networks. If several computers are simply connected together, they cannot communicate. Therefore, when we talk about computer "interconnectivity," we actually mean that these interconnected computers can already communicate. That is to say, from a functional perspective, these computers have already formed another large computer network and have made sense. 1. Relay The devices that connect these devices to each other are called relays. According to the hierarchy of the relay system, we often refer to the following types of relays: 1. Physical layer, repeater, first layer 2. Data link layer, bridge, second layer 3. Network layer, router, three-layer 4. A hybrid bridge with both bridge and router functions 5. Relay systems and gateways above the network layer When there is only a relay system, we generally do not talk about network interconnection because it only expands the network, which is still a network. When high-level gateways are complex, they are rarely used. When we discuss them, it generally refers to the retention of interconnections between switches and routers. Therefore, today we will discuss the differences between switches and routers. Network Switches 2. Definition of switches and routers Switching is a technical concept that completes the forwarding of signals from device entrances to exits. When used to describe devices in the second layer of a data network, it is a bridging device; If it is used to describe the third layer device of a data network, it is a routing device. The switch we often refer to is an Ethernet switch, which is actually a multi port second layer network dev

2023-10-27 What are the differences and models between the wireless router module and the WiFi control gateway module With the increasing development of wireless communication technology in the Internet of Things, WiFi has a wide network coverage and convenient mobility. Fast transmission speed and easy installation. Advantages such as health and safety. It has been widely used in daily life. The WiFi module integrates the WiFi wireless network protocol IEEE802.11b.g.n protocol stack and TCP/IP protocol stack functions into the module, and exports multiple interfaces. Traditional hardware devices embedded with WiFi modules can directly connect to the Internet using WiFi, which is an important component of achieving wireless smart homes, WiFi remote control, and other IoT applications. Based on the interface or integrated function introduced by the WiFi module. The WiFi module is further divided into serial port WiFi module, SDIOWiFi module, SPI interface WiFi module, AP module, router WiFi module, WiFi control module, etc. The wireless router module extends the interface types and some functions of the router, integrating WiFi functions for modularization. Its protocol and driver rely on a chip with powerful Flash and Ram resources and a LINUX operating system, also known as an embedded WiFi module. After communication between wireless intelligent router modules through WiFi, due to its new network transparent structure, the data transmission capacity of WiFi is very large, and it can even transmit video and audio streams. The wireless router module can choose between local area network (LAN) and wide area network (WAN) based on different application scenarios. Local Area Network (LAN) is a regional network formed in a local area, characterized by limited distribution area, which can be large or small, ranging from the connection between a building and adjacent buildings to the connection betwe

2023-10-20 Is WiFi still useful when 5G arrives? Entering 2019, the popularity of 5G continues to rise. Compared to the previous 4G, the transmission rate of 5G has significantly improved. According to the plan of the Ministry of Industry and Information Technology, China will start the large-scale commercial use of 5G by 2020. So will the rise of 5G have an impact on WiFi? What is the difference between 5G and WiFi? Firstly, let's talk about the differences between the two. Although both provide online services for users, 5G and WiFi are completely different in terms of operation and functionality. Firstly, the so-called 5G refers to the general term for the fifth generation mobile communication network technology, which must rely on licensed frequency bands for operation. In other words, operators must pay to use the 5G communication frequency band after obtaining it. In order to ensure the continuity and coverage of services, a large number of base stations must be built for each generation of mobile communication networks, otherwise users will experience data interruption after exceeding the coverage range of the base stations. I remember that in the 4G era, to ensure uninterrupted data signals, the distance between two base stations cannot exceed 800 meters. Building so many base stations is undoubtedly a huge cost for operators, and this cost can only be reflected in the initial traffic expenses. 5G Module The biggest difference between WiFi and 5G is that it is based on wireless transmission technology and uses a universal frequency band. There is no need for a telecommunications operation license, let alone payment of usage fees. Anyone can access the network as long as it is within the reach of the router. Currently, WiFi has two fre

2023-10-12 The difference between wireless AP and wireless router Wireless AP, also known as Access Point, is a wireless access point. AP is an access point for mobile terminals to enter wired networks, mainly used for enterprise wireless network coverage, with wireless coverage distances ranging from tens of meters to hundreds of meters. A wireless router is a wireless AP with routing function, which is actually a combination of router, switch, and wireless AP. wall AP Wireless AP generally has simple functions, but due to its support for PoE power supply, the construction difficulty is very low, and the deployment is simple, plug and play. And the AP supports centralized AC management, so it can perform batch upgrades, restarts, password changes, and SSID operations on the AP. When there are a large number of APs, the advantage is more obvious. AP cannot directly connect to the internet. Wireless routers have NAT address translation and can connect to the internet. Wireless routers can replace APs, but APs cannot replace wireless routers. Router LAN-LAN cascading enhances wireless signal and expands network coverage. WiFi 5 ceiling wireless AP Professional wireless AP, mainly aimed at enterprise applications, can carry a large number of wireless clients and has a higher price. Wireless routers are mainly designed for households, with generally lower configurations and a smaller number of wireless clients that can be carried. When the number of devices increases, various problems such as slow network speed and even frequent disconnection may occur. Of course, with the upgrading of wireless routers, issues with high configuration home routers are also rare. WiFi 6 ceiling wireless AP

2023-10-06 Is it true that the more antennas a router has, the better the signal and faster the speed? Many friends often see advertisements from businesses promoting "N (N>4) antenna, better signal penetration, and super fast speed when purchasing routers[ Is it true that the more antennas, the better the signal, and the faster the speed? This is the MIMO technology we are going to talk about today. 5G CPE Just like the principle of Superman becoming stronger with just one punch, routers do not become stronger because they have more antennas, but because with MU-MIMO, routers with more antennas have the opportunity to become stronger. Don't look at the number of antennas in the router, carefully check how many MU-MIMO channels it supports Budget allows for direct purchase of Wi Fi 6 routers, even 2.4GHz devices can benefit from this If the router is a directional antenna, remember to pair the antennas according to the left and right relationship when networking, with angles of 45 ° and 135 ° respectively 4G CAT4 CPE MIMO (Multiple Input Multiple Output) technology refers to the use of multiple transmitting and receiving antennas at the transmitting and receiving ends, respectively, to transmit and receive signals through multiple antennas at the transmitting and receiving ends, thereby improving communication quality. It can fully utilize spatial resources and achieve multiple transmission and reception through multiple antennas. Without increasing spectral resources and antenna transmission power, it can exponentially increase the system channel capacity. In the 2.4GHz era of wireless routers, SU-MIMO technology, also known as "single user multiple in multiple out" technology, was adopted. In fact, when routers were working, they queued all connected devices and then, based on the logic of the processor and firmware, issued network requests to each device one by one or in turn. 4G CAT6 CPE

2023-09-15 Why are high-end wireless routers so expensive? Unconsciously, Wi Fi has been entering our lives for many years, especially in today's popular internet and smartphones, which have become an indispensable and important element in our lives. For home users, wireless routers are not only essential devices for accessing the internet, but also the simplest and most direct device for generating Wi Fi signals. In the early days, wireless routers were relatively expensive, but now the cheapest home wireless router can be bought for a few tens of yuan, which can be said to be a conscience in today's rising prices. However, looking further, we found that high-end wireless routers are still relatively expensive, with some even reaching over 2000 yuan in price. So what is the price of high-end wireless routers compared to household wireless routers priced at tens of yuan? 1. Wireless specifications High end wireless routers typically support the latest wireless specifications, such as 802.11ac, as well as dual frequency concurrency at 2.4GHz and 5GHz. Although low-priced products represented by intelligent wireless routers are now supporting 802.11ac and 2.4GHz/5GHz dual frequency, with a price of only one or two hundred yuan, their wireless transmission rate is not high. Generally, it is 1167Mbps (300+867Mbps), while high-end wireless routers can reach 1900Mbps (600+1300Mbps) or even higher. 2. Hardware performance Before the concept of intelligent wireless routers, high-end wireless routers had already taken on this role. The equipment of CPU, memory, and external storage is like a small computer. Intelligent wireless routers that are not priced too low are usually equipped with inexpensive processors such as MediaTek MTK, as well as 64MB or 128MB of memory, while high
