Quality WiFi7 Module & WiFi HaLow Module manufacturer

As Wi-Fi evolved from Wi-Fi 6 and Wi-Fi 6E to Wi-Fi 7, the industry's focus shifted to high-speed connectivity capabilities such as 320MHz, 4096-QAM, and MLO. However, entering 2026, a more noteworthy change is taking place: the value of Wi-Fi 7 is shifting from "faster wireless networks" to "a smarter, more reliable, and more convergent terminal connectivity platform."   At the same time, as technologies such as Bluetooth 6.0, Matter, Thread, Wi-Fi Sensing, and edge AI continue to mature, AI PCs, robots, smart homes, industrial IoT, smart healthcare, and new energy equipment are placing more complex demands on wireless connectivity. This means that the competitive logic for next-generation wireless communication modules is changing: From a single Wi-Fi connection to Wi-Fi + Bluetooth + multi-protocol collaboration; from simply transmitting data to the integration of connectivity, sensing, and edge intelligence. For wireless communication module manufacturers, the real opportunity is no longer just "bringing Wi-Fi 7 into devices", but helping terminal manufacturers build more complete smart connectivity capabilities. I. Wi-Fi 7 is entering a true stage of large-scale deployment, but "high speed" is just the beginning. The most representative technologies of Wi-Fi 7 include 320MHz channels, 4096-QAM, and Multi-Link Operation (MLO). These technologies can significantly improve throughput, reduce latency, and enhance connectivity in complex network environments. However, if we only understand Wi-Fi 7 as "faster Wi-Fi", we are actually underestimating its future value in the IoT market. According to IDC data, in the first quarter of 2026, Wi-Fi 7 accounted for 44.5% of global enterprise WLAN-dependent access point (AP) revenue , a significant increase from 11.8% in the first quarter of 2025. IDC believes that Wi-Fi 7 has become a major driver of growth in enterprise wireless networks. In terms of terminal scale, the Wi-Fi Alliance predicts that global shipments of Wi-Fi 7 devices will reach approximately 1.1 billion units in 2026. Among them, IoT devices will account for approximately 196.1 million units . These two data points deserve special attention. Because it illustrates: The growth of Wi-Fi 7 is no longer limited to routers and enterprise APs; IoT devices are becoming an important source of growth in the next phase. For the module industry, this means that Wi-Fi 7 is expanding from "high-performance network equipment solutions" to "terminal connectivity solutions".   II. The Real Change: Wi-Fi 7 is Entering the IoT, and the IoT's Need for "Speed" is Not as High as Imagined Traditional Wi-Fi 7 emphasizes: 320MHz 4096-QAM Multi-link operation High throughput Multi-user concurrency However, many IoT devices do not require peak speeds of several Gbps at all. For example: Devices such as smart door locks, environmental sensors, smart lighting, HVAC controllers, and industrial sensors may not generate a large amount of data, but they are more concerned with: Connection stability, low power consumption, low latency, reliability under network congestion, and long-term operating capability. Therefore, a very important industry assessment is: The next wave of growth for Wi-Fi 7 may not come from "faster devices," but rather from "more devices starting to use Wi-Fi 7." This is also a structural change that the wireless module industry should pay attention to.   III. AIoT is redefining wireless modules: connectivity is only the first layer of capability. AI is changing how data is processed in IoT devices. Traditional IoT is more about: Sensor → Data Acquisition → Cloud → Command Return And AIoT is gradually becoming: Sensors/cameras/microphones → Local AI inference → Real-time decision-making → Cloud collaboration → Multi-device联动 (Multi-device linkage) This means that the amount of data generated and processed by terminal devices is constantly increasing, while requiring more stable inter-device communication. 21.1 billion in 2025 and is projected to reach approximately 39 billion by 2030 . The increase in the number of devices is only the first layer of change. More importantly, an increasing number of IoT devices are beginning to possess: AI algorithms NPU Local reasoning Voice interaction Visual recognition Multi-sensor fusion Edge computing capabilities Counterpoint Research also identified Edge AI as a key technology direction in its CES 2026 analysis, covering multiple fields such as AI vision, intelligent sensing, edge computing, and AIoT devices. Therefore, wireless modules in the AIoT era are no longer just "networked devices," but are increasingly becoming the connectivity infrastructure in terminal intelligent systems.   IV. From AI Robots to Smart Terminals: Why is Wi-Fi 7 Becoming More and More Important? Robots are a very typical example of observing this trend. A robot with vision, voice, and edge AI capabilities may simultaneously need: **Wi-Fi:** Connect to the cloud, transmit images, perform OTA upgrades, and access AI services; **Bluetooth:** Connects to mobile phones, headphones, gamepads, and other peripheral devices; **UWB/Positioning Technology:** Enables spatial positioning and device interaction; **Thread/Matter:** Connecting the smart home ecosystem; **Edge AI:** Completes local vision, speech, and behavior judgments. Therefore, future robots will not simply be "equipped with a Wi-Fi module". It's more like a: AI computing platform + multi-sensor platform + multi-wireless communication platform. The Wi-Fi Alliance's assessment of Wi-Fi trends for 2026 also explicitly mentions that AI, robotics, automotive, and predictive maintenance are driving Wi-Fi into more industrial IoT applications; in the consumer IoT field, the Matter ecosystem is also further promoting Wi-Fi applications. This means: Robots, AI terminals, smart gateways, and other new devices are likely to become important application scenarios for Wi-Fi 7 modules in the future. V. Bluetooth 6.0 is changing the definition of "Bluetooth module" If Wi-Fi 7 is solving the problem of "high-speed, reliable connectivity", then Bluetooth 6.0 is enabling Bluetooth to evolve from a traditional "short-range connectivity technology" to positioning, ranging, and spatial awareness . The Channel Sounding introduced in Bluetooth Core 6.0 enables more accurate distance measurement through methods such as Phase-Based Ranging (PBR) and Round-Trip Timing (RTT). The Bluetooth SIG believes that this technology will provide new application possibilities for scenarios such as digital keys, asset tracking, smart homes, and industrial equipment. The Bluetooth SIG predicts that global annual shipments of Bluetooth devices will reach approximately 5.9 billion units by 2026 . This means that the application scope of Bluetooth is expanding. past: Bluetooth = connection to headphones, keyboard, mouse, and mobile phone future: Bluetooth = Connectivity + Location + Ranging + Device Discovery + Low Power Awareness Therefore, Wi-Fi 7 and Bluetooth 6.0 are not two independent technological paths. In an increasing number of terminal devices, both will coexist: Wi-Fi is responsible for high-speed IP connectivity, while Bluetooth is responsible for low-power device connectivity, network configuration, peripheral devices, and spatial awareness. This is why next-generation wireless modules are increasingly emphasizing the integration of Wi-Fi and Bluetooth.   VI. From Wi-Fi + Bluetooth to Wi-Fi + Bluetooth + Thread: Multi-protocol convergence is becoming a trend Smart home is the most typical application scenario for the integration of multiple protocols. A complete smart home system may exist simultaneously: Wi-Fi camera Bluetooth door lock Thread sensor Matter Smart Light Wi-Fi gateway Bluetooth remote control Different devices have completely different requirements for power consumption, bandwidth, coverage, and network topology. Therefore, the future of smart homes is not about one protocol "eliminating" another, but about different protocols taking on different roles. More notably, solutions have emerged in the market that integrate Wi-Fi 7, Bluetooth LE, and Thread/802.15.4 onto the same chip platform. This shows that: Multi-protocol integration has moved from the "concept" stage to the productization stage of chips and modules. VII. The real competition in wireless modules is shifting from "chip performance" to "system integration capabilities". The chip is the core of the wireless module, but the chip itself cannot directly determine the connection experience of the final product. From chip to end product, there are still many engineering steps in between: Chip → RF Design → PA/LNA → Filtering and Matching → Antenna → PCB → Driver → Operating System → Protocol Stack → Authentication → Mass Production The issue of radio frequency coexistence will become even more important as Wi-Fi and Bluetooth are increasingly integrated into the same module. 8. From Chips to Modules: The Industry Chain is Entering a "Platformization" Stage From the current perspective of the industrial chain, this change is already quite evident. Qualcomm is continuing to advance Wi-Fi 7, Bluetooth, and next-generation wireless connectivity platforms for AI experiences. Its official product roadmap has expanded from Wi-Fi 7 to Wi-Fi 8, which emphasizes reliable and intelligent connectivity. Chip manufacturers such as Realtek are also continuously promoting the integration of wireless connectivity capabilities such as Wi-Fi 6E, Wi-Fi 7, and Bluetooth. Meanwhile, domestic manufacturers are accelerating their entry into the high-performance Wi-Fi market. QOGRISYS has already developed Wi-Fi 7 and Wi-Fi 6 modules based on Qualcomm and Wuqi chips , supporting applications such as 2T2R, dual-band, and SDIO. The underlying industry logic is very clear: Chip manufacturers provide the connectivity platform, while module manufacturers are responsible for truly transforming chip capabilities into end-user, mass-producible, and certifiable products. Future module platforms may simultaneously possess: Wi-Fi + Bluetooth + Thread/802.15.4 + AI computing + Sensing Wireless modules are evolving from "a communication device" to "a smart connectivity platform". 9. QOGRISYS: Extending from Wi-Fi modules to multi-scenario wireless connectivity capabilities For terminal equipment manufacturers, standard upgrades are only the first step. Real product development also needs to consider: Performance, size, power consumption, interface, antenna, radio frequency, operating system, certification, and mass production cost. This is also the key value of QOGRISYS's long-term strategic layout in wireless communication modules. In terms of product portfolio, QOGRISYS has formed a product layout that includes Wi-Fi modules, Bluetooth modules, Wi-Fi HaLow, NearLink, PLC modules, and IoT/AIoT modules , covering application areas such as artificial intelligence, smart home, industrial internet, consumer digital products, telemedicine, and new energy. Regarding Wi-Fi 7 products, O2072PB, O2072PM, and other products are currently listed on the O2072PB/O2072PM product page. Among them, O2072PB/O2072PM are labeled as 802.11be + Bluetooth 6.0, 2T2R, and 5.8Gbps . This means that there is a relatively direct correspondence between QOGRISYS's product roadmap and industry trends: Wi-Fi 7 → High-performance wireless connectivity Bluetooth 6.0 → Low-Power Connectivity and Spatial Awareness AIoT → Local Intelligence and Edge Computing PLC → Energy and Industrial IoT Communication Multi-protocol → Converged connectivity for complex terminal scenarios Therefore, a more complete connectivity technology chain is being formed, from chips to modules, and then from modules to end applications. 10. The true value of Wi-Fi 7 lies in making the connection between smart devices more reliable. If you look at the development of the entire industry together, you'll find that the significance of Wi-Fi 7 is changing. Wi-Fi 4 era: Solve the problem of "Is there a wireless network?". The Wi-Fi 5 era: Solve the problem of "Is the wireless network fast enough?" Wi-Fi 6 era: How to solve the problem of "many devices connecting to the network at the same time". Wi-Fi 7 era: The task began by addressing how to maintain reliable connections in high-performance, multi-device, low-latency, and complex network environments. The AIoT era has raised new questions: The device not only needs to be connected to the network, but also needs to sense, compute, coordinate, and make autonomous decisions. Therefore, Wi-Fi 7 is just the starting point of this change. The real next stage is: Wi-Fi + Bluetooth + Thread/Matter + AI + Sensing + Edge Computing Together, they form the connection base for the next generation of smart terminals.    

I. Industrial Transformation: A Decade of Leap from "Visible" to "Comprehensible" Over the past decade, the security monitoring industry has undergone a profound transformation, evolving from analog to digital, from wired to wireless, and from passive recording to proactive sensing. IPCs (IP Cameras) have evolved from simple video acquisition devices into distributed intelligent sensing nodes that integrate optical imaging, edge computing, intelligent analysis, and wireless connectivity. The global market size for smart IP cameras (IPCs) reached approximately US$17.389 billion in 2025, and is projected to grow to US$18.418 billion in 2026, and potentially reach US$26.092 billion by 2032, with a projected compound annual growth rate (CAGR) of 6.0% from 2026 to 2032. From a broader perspective, the global video surveillance market size was US$87.24 billion in 2025, and is projected to reach US$242.17 billion by 2034, with a CAGR of 12.01% . The core drivers of this round of growth come from three levels: the explosive growth in demand for AI video analytics from enterprises to governments, the implementation of mandatory video surveillance regulations in various regions, and the replacement of traditional on-premises deployment models by cloud-managed video platforms . II、Core technology trends: AI, wireless technology, and low power consumption are redefining product features. 2.1 AI is moving from the cloud to the edge, and its penetration rate continues to rise. Artificial intelligence is permeating every aspect of security monitoring at an unprecedented pace. The value of IPC's products has expanded from basic indicators such as image clarity, night vision capabilities, and structural protection to intelligent functions such as human detection, human and vehicle classification, facial recognition, license plate recognition, perimeter intrusion detection, voice recognition, passenger flow statistics, and event retrieval . As security systems shift from passive recording to proactive early warning, the computational burden on cameras continues to increase. Demand for edge AI inference chips is surging, with penetration expected to reach 65% by 2025, a 28 percentage point increase from 2023 . The focus of future competition will not only be on hardware parameters, but also on algorithm accuracy, false alarm control, platform openness, remote operation and maintenance efficiency, data security, and multi-scenario adaptability . 2.2 Wirelessization: From "Optional" to "Required" Wireless connectivity technology is profoundly changing the way IP devices are deployed and their application boundaries. Industry demand is expanding across multiple paths, including home consumption, commercial stores, industrial parks, urban governance, traffic management, and industrial sites. Wireless solutions can save 30% to 50% on cabling and maintenance costs , with particularly significant advantages in distributed monitoring scenarios. In terms of product structure, global shipments of consumer IPCs are projected to exceed 192 million units in 2025 , representing a year-on-year increase of approximately 11.6%. Among these, low-power IPCs account for 48 million units, and 4G IPCs account for 40.32 million units . These two product categories are driving the upgrade of IPCs from "passive monitoring" to "proactive sensing." In terms of connectivity technology, the mainstream solutions in the industry have evolved from a single Wi-Fi solution to a pattern where multiple wireless technologies coexist. 2.3 Low power consumption: Opening up new scenarios of "no power and no network". Breaking free from dependence on fixed power supplies and stable broadband networks has become an irreversible industry trend. The low-power IPC market grew by approximately 30% in 2024. It is projected to reach 25 billion yuan by 2026 . The maturity of AOV (Always on Video) technology represents a significant breakthrough in the field of low power consumption—based on ultra-low power memory and fast startup/standby technology, it enables 24/7 uninterrupted recording capability . This technology allows IPCs to record in a low frame rate power-saving mode when there are no events, significantly extending the battery life of battery-powered devices. III、Application Scenarios Panorama: From Home Security to Full-Scenario Intelligence 3.1 Home and Micro-enterprise Scenarios: The Explosion of the Consumer Market The product form in the consumer market is rapidly evolving. In the domestic market, multi-lens cameras account for 75% , becoming the absolute mainstream. Low-power products account for 25%, and 4G IPCs account for 21% . 3-megapixel to 5-megapixel cameras have become the mainstream configuration. The core needs of the home environment have evolved from "visible" to "understandable" —features such as low cost, easy installation, mobile experience, cloud storage, voice interaction, privacy protection, and pet or baby recognition have become the focus of competition . In home settings, Wi-Fi modules play a crucial role. They enable monitoring devices to connect wirelessly to the internet or a local area network, facilitating data transmission and remote monitoring . 3.2 Commercial and Industrial Park Scenarios: Core Tools for Intelligent Management In commercial buildings and industrial parks, the value of IPCs has expanded from simple security monitoring to an operational management tool. This scenario focuses on continuous monitoring, access control linkage, passenger flow analysis, personnel management, and cross-location retrieval, driving deep integration of cameras with NVRs, VMSs, cloud platforms, and security management systems . In 2025, the digital transformation of commercial buildings and industrial parks will drive steady growth in the procurement of security equipment . The deployment of computer vision for customer flow analysis and behavior prediction in the retail sector will continue to increase. 3.3 Urban Governance and Transportation Scenarios: The Main Battlefield for Large-Scale Deployment Government public safety and smart city projects remain the largest downstream scenario, continuing to contribute about 35% of the demand . In the field of intelligent transportation, integrated security systems based on roadside sensing units cover key road sections in more than 1,200 cities worldwide. The demand for security upgrades in transportation scenarios (airports, railways, ports) continues to grow . Urban governance, transportation, and industrial scenarios require stronger environmental adaptability, longer recognition distances, higher structured recognition accuracy, and greater reliability, driving the growth of high-pixel, PTZ, multi-lens, thermal imaging, 4G or 5G access, explosion-proof and corrosion-resistant, and industry-specific models . IV. Ofeixin Dedicated Wireless Module Product System for IPCs Wireless connectivity technology plays an increasingly crucial role in the entire IPC industry value chain. As a professional IoT wireless module solution provider, Ofeixin currently focuses on promoting three dedicated Wi-Fi modules for the consumer market in the IPC network camera field: O9101UD, 6188E-UF, and F89FTSM13-W7 , each positioned for different technology generations, interface solutions, and application scenarios. 4.1 O9201SB and O9101SA: Wi-Fi 6 Dual-Band High-Speed Modules Both the O9201SB and O9101SA are based on the Wuqi Wi-Fi 6 chip solution, supporting the 802.11ax + BLE 5.3 protocol. They adopt a 2.4GHz/5GHz dual-band synchronous (DBS) architecture, achieving speeds up to 886Mbps, and support core Wi-Fi 6 technologies such as MU-OFDMA and MU-MIMO. Both modules use a USB 2.0 interface and support the full range of WPA/WPA2/WPA3 protocols for security.   In IPC scenarios, dual-band concurrency effectively avoids stuttering and disconnections caused by single-band congestion. The high bandwidth is sufficient to support real-time transmission of 4K ultra-high-definition video streams, making them suitable for mid-to-high-end home IPCs and commercial surveillance cameras. 4.2 6188E-UF: High-performance USB Wi-Fi module The 6188E-UF is based on the Realtek RTL8188FTV solution, supporting IEEE 802.11 b/g/n, 2.4GHz band, 150Mbps speed, USB 2.0 interface, and measuring only 12.2×13mm . The module highly integrates all functions such as MAC, BB, and PA, requiring only a few external components on the PCB, significantly reducing the overall design complexity. For security, it supports WPA/WPA2/WPA3 enterprise-level certification and has obtained CMIIT ID approval. In IPC scenarios, the core advantage of the 6188E-UF is its mature and reliable solution that brings a highly competitive cost structure. The plug-and-play USB interface greatly reduces the difficulty of adaptation and has been widely verified in fields such as IPC/NVR, set-top boxes, and dashcams . 4.3 F89FTSM13-W7: Compact Wi-Fi Module with SDIO Interface The F89FTSM13-W7 is based on the Realtek RTL8189FTV solution, supports IEEE 802.11 b/g/n, 2.4GHz band, 150Mbps speed, SDIO 2.0 interface, and is the smallest of the three products, measuring only 12×12mm. This module is a single-chip 1×1 SISO WLAN SDIO controller, fully compliant with the 802.11n specification, and supports WPA/WPA2 enterprise-level security authentication and AES encryption. In IPC scenarios, the core advantage of the F89FTSM13-W7 lies in the superior data transfer efficiency and CPU usage of the SDIO interface compared to USB, while its ultra-small size provides greater flexibility for compact PCB design . This module has been widely used in tablets, smart TVs, IPTV/OTT, IPCs, AI speakers, and other fields, and is especially suitable for products with strict space constraints, such as mini cameras and embedded monitoring modules. V. Industry Challenges and Future Outlook 5.1 Safety compliance has become a hard threshold. The global regulatory framework is expanding from traditional product security standards to mandatory cybersecurity protocols and data localization requirements. Smart cameras involve public safety, personal privacy, cybersecurity, and cross-border data flows, leading governments and critical infrastructure procurement to increasingly prioritize equipment origin, vulnerability response, data compliance, and supply chain trustworthiness . In 2025, Europe will officially implement a new version of its cybersecurity directive, requiring all networked security devices to pass baseline security certification before they can be sold. China will also release detailed implementation rules for the "Regulations on the Administration of Public Security Video Image Information Systems" in 2025, strengthening data privacy and restrictions on cross-border transmission. 5.2 The competitive landscape is shifting from hardware to comprehensive capabilities. The supply landscape exhibits a coexistence of globalized manufacturing and regionalized market access . Mainland Chinese manufacturers possess advantages in product portfolio completeness, large-scale manufacturing, cost control, and industry project coverage. The industry is expected to continue growing, but competition will shift from simple hardware price to a comprehensive competition encompassing hardware, algorithms, cloud platforms, compliance certifications, and service capabilities . The top five companies in the global IP camera market (Hikvision, Dahua, Axis Communications, Hanwha Vision, and Motorola Solutions) collectively held 84.2% of the market share in 2025 , indicating a continued increase in industry concentration. 5.3 The value of software and services continues to rise. The industry's profit structure is undergoing profound changes. The proportion of cloud platform deployments is expected to surpass 30% for the first time in 2025. Software is capturing a larger share of market value , and customers are shifting from purchasing equipment to purchasing outcome-driven solutions. The widespread adoption of Video Surveillance as a Service (VSaaS) is driving a continued rise in software penetration. 5.4 Future Directions: From "Video Acquisition" to "Intelligent Sensing and Decision-Making" The industry is transforming from "video capture" to "intelligent perception and decision-making," and cameras are becoming one of the most important AI sensors in the physical world . Key dimensions of future competition will include: algorithm accuracy and false alarm control, platform openness and remote operation and maintenance efficiency, data security and multi-scenario adaptability, compliance certification and supply chain credibility.  

I. Industry Trends: PLC Technology Ushers in a "Return to Value" In August 2026, Huawei released Lingxiao PLC 3.0 networking technology, once again bringing PLC (Power Line Carrier Communication) into the industry spotlight. Meanwhile, the revision of domestic PLC power line carrier standards began at the beginning of the year, with in-depth discussions focusing on four major scenarios: industrial lighting, outdoor streetlights, smart home systems, and hotels. In the international market, the launch of the Matter-PLC bridge enabled interconnectivity between the domestic PLC ecosystem and global Matter ecosystems such as Apple HomeKit and Samsung SmartThings. A series of signals indicate that PLC technology is undergoing a profound "value return" —from its early single application mainly in smart meters, it is rapidly penetrating into diversified scenarios such as smart homes, smart cities, and the Industrial Internet of Things. With its unique advantage of "where there is electricity, there is internet," it has become one of the core solutions for the new generation of smart connectivity. II. Technical Analysis: Why PLCs Have Become "Invisible Infrastructure" The fundamental difference between PLC-IoT and traditional wireless solutions lies in the underlying communication logic. Wireless modules (Wi-Fi, Zigbee, Bluetooth Mesh) rely on spatial electromagnetic waves to propagate signals, operating in the 2.4GHz/5GHz frequency band. When the signal passes through walls, it experiences significant attenuation due to load-bearing concrete walls and metal cabinets, and also faces co-channel interference . In contrast, PLC-IoT uses existing 220V/380V power lines in the home as the data transmission medium. The signal travels along the power lines and is unaffected by physical obstructions from walls, floors, or metal structures —as long as the circuit is powered, the communication link remains stable . The actual test data is even more convincing: the end-to-end response latency of PLC-IoT is stable within 50 milliseconds , and the communication success rate is nominally as high as 99.99% ; a single host can support 128–384 device nodes ; academic research has also confirmed that PLC-IoT has comprehensive advantages over ZigBee and KNX technologies in terms of stability, cost-effectiveness and anti-interference ability . More importantly, there is a transformation at the engineering level – PLC-IoT achieves true “no wiring required” : simply add a smart host to the distribution box, and you can achieve whole-house communication coverage through existing wiring . III. Ofeixin PLC Module Product Matrix: A "Connection Base" Covering All Scenarios As a professional enterprise deeply involved in the field of PLC technology, Shenzhen Ofeixin Technology Co., Ltd. has formed a complete technology matrix in this field, from chip-level modules to full-stack system solutions. The 3121N-H is a fully integrated power line carrier communication module developed by Ofeixin based on the Hisilicon Hi3121S chip. It operates in the 0.5-3.7MHz and 2.5-5.7MHz frequency bands, and its protocol is based on a subset of the IEEE 1901.1 standard , allowing it to interconnect with chips using the same standard subset. In terms of core performance, the physical layer peak rate is 0.507 Mbit/s and the application layer rate is 80 Kbps ; it is equipped with a 200MHz ARM Cortex-M3 processor with 256KB SRAM; a single CCO can support up to 200 STA nodes , supports dynamic routing and multi-path automatic addressing, and a typical 200-node Layer 2 network can be completed within 10 seconds . In terms of communication reliability, it adopts OFDM modulation, supports BPSK/QPSK, and has FEC forward error correction and CRC check; it also supports TDMA and CSMA/CA mechanisms, providing 4 levels of QoS guarantee ; the receiving sensitivity is better than 0.2mVpp. In terms of engineering, it measures only 23.5×30mm , integrates built-in wire drive and onboard coupling circuitry, and provides a rich set of interfaces such as UART, PWM, GPIO, I2C, and ADC; static power consumption is ≤0.15W, and dynamic operating power is ≤0.7W . The S130N-ISI is a fully integrated power line carrier communication module developed by Ofeixin based on the Lianxintong VC6330 chip. It uses an LCC package and measures only 20.6×12.6mm , making its ultra-miniaturized design suitable for space-constrained devices. In terms of core architecture, it integrates a 32-bit ARM Cortex-M3 MCU and a 32-bit DSP dual-core processor , equipped with embedded Flash and 1MB of on-chip SRAM . The two cores work together, with the MCU responsible for the protocol stack and system control, and the DSP dedicated to physical layer signal modulation and demodulation, resulting in better communication performance in complex power line environments. In terms of communication protocols and modulation, it supports both China SGCC Q/GDW 11612 and IEEE 1901.1 protocols , supports multiple modulation methods such as BPSK, QPSK, and 16QAM, supports SGCC 0-12MHz bandwidth and provides multiple selectable frequency bands, which can be flexibly configured according to the scenario. In terms of interfaces and development support, it provides a rich set of interfaces including UART, PWM, GPIO, ADC, SPI, and I2C. Ofeixin also provides a full-stack solution and a development toolchain for deep collaboration with the cloud platform, integrating modules, coupling circuits, and power modules, supporting 220V direct connection testing . This one-stop support effectively reduces the development threshold and cycle time for terminal manufacturers. IV. Scenario Value: The "Connecting Foundation" from Smart Homes to Smart Cities The value of PLC technology lies in its unique advantage of "having a network wherever there is electricity" —it eliminates the need for additional communication cables, allowing the construction of a communication system directly using the existing power network, thus achieving "one power line, two uses". In smart home scenarios , the value of PLCs is being fully validated by leading companies. Huawei's HarmonyOS smart home solution uses wired PLC connections to replace many wireless solutions that rely on WiFi/Zigbee, achieving a claimed communication success rate of 99.99% . At the 2026 AWE exhibition, Haier launched a new generation of PLC smart home solutions based on Lihe Micro PLCs, adopting a PLC-Mesh architecture and possessing core advantages such as "direct device connection, ultra-fast response, local decision-making, and availability even when the network is down ." Ofeixin's 3121N-H and S130N-ISI modules are indispensable communication nodes in these whole-house smart solutions—from lighting control and smart curtains to central air conditioning, PLC modules make "no blind spots in the whole house, and controllable even when the network is down" a reality . In smart city scenarios , PLC technology demonstrates its "infrastructure-level" connectivity value. According to actual test data, under a standard urban power grid environment, PLC-IoT technology can achieve reliable communication over a distance of 500 meters , with the latest chip solutions even reaching 2400 meters . Eastsoft Carrier has launched an "AI + Road Lighting Integrated Solution," centered on an AI intelligent agent and integrating PLC and Cat.1 dual communication technologies, which has been implemented in multiple locations across the country. In scenarios such as smart streetlights, smart parking, charging piles, and photovoltaic communication , Ofeixin's 3121N-H and S130N-ISI modules achieve reliable communication between devices through existing power lines, eliminating the need to lay separate communication lines for each terminal— a single power line provides both power and communication , representing a true "new infrastructure" connectivity paradigm. In industrial and energy scenarios , the application boundaries of PLCs are expanding from the electricity meter end to the energy Internet of Things (IoT) end . With the large-scale access of new loads such as distributed energy and electric vehicle charging networks, the growth drivers of PLC chips and modules are shifting from the increase in the price of a single chip to multiple drivers such as the expansion of application nodes, the upgrade of dual-mode communication, and the spillover of energy management scenarios . V. Looking to the Future: Ofeixin and the New Paradigm of PLCs complete PLC module product matrix, full-stack system solutions, and deep cooperation with chip manufacturers , Ofeixin is occupying a key position in this PLC technology wave. Whether it's smart home lighting control and smart curtains, or smart city street lighting and charging pile communication— wherever there is electricity, there are Ofeixin's connectivity solutions . The return to value of PLC technology is essentially a rethinking of the essence of "connectivity": the most reliable connections are often hidden in the most basic power lines . Ofeixin is moving forward with this new paradigm.
