Quality WiFi7 Module & WiFi HaLow Module manufacturer

I. A trillion-yuan existing market is opening up China's hotel industry has entered a stock era. Over the next three years, 732,000 rooms older than 15 years will enter a concentrated renovation cycle , with the market size already exceeding 100 billion yuan . Since 2026, the number of renovation contracts signed has already surpassed the total number for the entire previous year, and "renovation" and "rebranding" are becoming accompanying actions in the upgrading of China's hotel stock . The core challenge of renovating existing hotels lies in the need to upgrade guest rooms with smart technology while maintaining operations and minimizing disruption to guests. This places demands on the construction costs and deployment flexibility of communication technologies far exceeding those of new projects. II . Market Trends The smart hotel market is currently experiencing a period of structural expansion. Market research firms predict that the global smart hotel market will grow to US$90.46 billion by 2032 , representing a compound annual growth rate of 14.20% . The Asia-Pacific region is the fastest-growing area, driven by high smartphone penetration, urban tourism expansion, and large-scale hotel modernization . In terms of connectivity technology, PLCs are transforming from a "supplement to wireless solutions" to a "connection base for hotel guest room control ." This judgment is based not only on Lihe Micro's implementation data but also on changes in the competitive landscape: Honeywell's INNCOM FLEX intelligent hotel guest room control system, released in September 2026, explicitly supports "wired and wireless dual deployment solutions" and is compatible with mainstream building protocols such as BACnet IP and Modbus TCP, reflecting the leading building automation manufacturers' recognition of the "multi-protocol compatibility and open deployment" approach . III . The Dilemma Between Wired and Wireless Traditional hotel guest room control systems face a structural dilemma. Wired solutions (RS-485 bus, TCP/IP Ethernet) offer stable and reliable communication with strong anti-interference capabilities and no data packet loss issues, but require the laying of dedicated communication cables. In existing renovation scenarios, this means trenching, ceiling removal, and wall repair, resulting in long construction periods and often requiring closure or phased construction, significantly impacting hotel operations . This type of solution is more suitable for new construction or complete renovation of high-end hotels . Wireless solutions (Bluetooth Mesh, Zigbee, Wi-Fi) offer flexible deployment options, requiring only the laying of power lines, making them cost-effective and easy to install in converted hotels . However, wireless signals face challenges in complex hotel structures, such as wall attenuation, metal cabinet obstruction, and co-channel interference, resulting in weaker communication stability compared to wired methods. Furthermore, the location of the equipment significantly impacts signal quality . No single technological approach can simultaneously meet the dual requirements of "uninterrupted transformation" and "highly reliable communication." What the industry needs is a third path. IV . PLC: Resolving the conflict between "existing power lines" and "new wiring". The core logic of PLC (Power Line Carrier Communication) differs fundamentally from traditional solutions. Wireless solutions rely on electromagnetic wave propagation, and signals experience significant attenuation when passing through load-bearing concrete walls and metal structures. In contrast, PLC uses the building's existing 220V/380V power lines as the data transmission medium. Signals travel along the power lines and are unaffected by physical obstructions from walls, floors, or metal structures—as long as the circuit is powered, the communication link remains stable . Real-world test data supports these technical characteristics: PLC-IoT end-to-end response latency is consistently below 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 confirms that PLC-IoT has comprehensive advantages over ZigBee and KNX technologies in terms of stability, cost-effectiveness, and anti-interference capabilities . For hotel renovation projects, the most valuable feature of PLCs is that they eliminate the need for wiring. V. Open ecosystems are replacing closed solutions The accelerated adoption of PLC technology in the hotel industry also benefits from the industry's reflection on "closed-loop guest room control solutions". Currently, most hotel smart guest room control projects adopt closed-loop solutions, with hotel systems, equipment, and platforms highly dependent on a single supplier. If a vendor experiences operational or technical issues, the entire guest room control system may be paralyzed. Furthermore, incompatible communication protocols between gateway devices from different brands prevent interoperability and hinder system expansion, resulting in persistently high costs for subsequent hotel upgrades, maintenance, and iterations . Based on a unified protocol standard, the PLCP ecosystem brings together products such as switch panels, light drivers, curtain motors, and temperature control panels from numerous equipment manufacturers. Hotels can flexibly select from multiple brands and categories, eliminating the supply chain risks of "one vendor monopolizing" products. This trend offers a clear message for module manufacturers: hotel customers are no longer simply buying "a gateway + a set of equipment," but are looking for "a standard + an ecosystem." As the underlying communication layer, modules need to be compatible with mainstream protocol stacks. VI . PLC module slots of Qogrisys Shenzhen Ofeixin Technology Co., Ltd. has developed two core module products for hotel scenarios in the PLC field. The 3121N-H (based on the HiSilicon Hi3121S) is based on a subset of the IEEE 1901.1 standard. A single CCO supports up to 200 STA nodes , dynamic routing, and automatic multi-path addressing. A typical 200-node, two-tier network can be set up within 10 seconds . The module size is 23.5×30mm, integrating built-in line drivers and onboard coupling circuitry, and providing interfaces such as UART, PWM, GPIO, I2C, and ADC. Qogrisys has also designed an integrated PLC + power supply kit with a built-in conversion transformer for direct connection to 220V bidirectional AC power, facilitating rapid product adoption by customer control solution providers . The S130N-ISI (based on the Leadcore VC6330) uses an LCC package, measuring only 20.6×12.6mm , making its ultra-miniaturized design suitable for space-constrained hotel panel devices. It integrates a 32-bit ARM Cortex-M3 MCU and a 32-bit DSP dual-core processor, supporting both China SGCC Q/GDW 11612 and IEEE 1901.1 protocols . The Leadcore VC6330 chip achieves an application-layer communication rate of up to 1Mbps, with a 99.99% communication success rate in actual projects and a Level 1 network communication latency of

I. Centralized Procurement Signal: The Iteration of Wi-Fi 7 for Home Gateways Enters Substantive Stage The centralized procurement of home network terminals completed by China Telecom and China Mobile in 2026 sends a clear signal to the industry: the role of Wi-Fi 7 in operators' home gateways and FTTR products is shifting from "flagship configuration" to "mainstream configuration" .   In China Mobile's 2026-2027 smart home gateway centralized procurement, Tianyi Technology was shortlisted as the third successful bidder for Package 1 and the sixth successful bidder for Package 2, with an estimated value of 208 million yuan. In China Telecom's FTTR centralized procurement, Tianyi Technology won two packages, with an estimated value of 273.6 million yuan. Jiulian Technology was shortlisted for China Mobile's GPON and 10G GPON packages, with market shares of 14.63% and 12.20%, respectively. The significance of these centralized procurements lies in the fact that operators' technology choices for home network terminals directly determine the upstream module demand structure for OEMs over the next 12 to 18 months . From a penetration rate perspective, the proportion of Wi-Fi 7 in FTTR terminals is rapidly increasing. According to IIM Information's "Global FTTR All-Optical Network Industry Outlook In-Depth Analysis Report," the proportion of FTTR terminals supporting Wi-Fi 7 is expected to reach 38.6% in 2026 , an increase of 17.2 percentage points compared to 2025. This growth rate is significant in the iteration of communication terminal technology, reflecting operators' clear willingness to invest in the evolution from "whole-house gigabit" to "whole-house Wi-Fi 7." II. Engineering Constraints of FTTR Architecture on RF Modules The core architecture of FTTR is a distributed network consisting of a main gateway and multiple sub-routers. Fiber optic backhaul solves the wired bandwidth problem between nodes, but the wireless coverage quality of each node directly determines the user's true perception of "gigabit throughout the house." This architecture imposes three engineering constraints on the radio frequency module that differ from those in a single-router scenario. First, latency consistency during multi-node handover. When users move between rooms, terminal devices need to complete roaming handovers between different sub-routers. Traditional Wi-Fi roaming mechanisms experience service interruptions on the order of 100ms during handover. For real-time applications such as video calls and online games, this interruption is sufficient to cause noticeable experience degradation. Wi-Fi 7's Multi-Link Operation (MLO) and its Enhanced Single-Radio Implementation (EMLSR) significantly reduce handover interruptions through link pre-sense and fast handover mechanisms. Huawei explicitly claims an ultra-low latency of 10ms in its Wi-Fi 7 FTTR solution . This is not just marketing hype, but a scenario-based realization of Wi-Fi 7 MLO capabilities. Second, scheduling efficiency under dense device concurrency. Modern homes typically have more than 20 devices online simultaneously, and in mid-to-high-end scenarios, this can reach over 40. While FTTR's distributed architecture expands coverage, it also means more radio frequency nodes operating in the same spectrum space, leading to increased inter-node interference and terminal scheduling complexity. Wi-Fi 7's optimized OFDMA resource scheduling and multi-link redundancy mechanisms offer far greater value in this scenario than in a single-router environment. Third, matching the fiber backhaul bandwidth. When the fiber backhaul between the FTTR main gateway and sub-routers provides 2.5Gbps or even higher bandwidth, if the wireless side still relies on Wi-Fi 6's 160MHz channel capability, it will become a bottleneck for end-to-end throughput. Wi-Fi 7's 320MHz channel and tri-band capability enable the wireless side to have the basic bandwidth supply to match the fiber backhaul. In this architecture, the role of the RF module is to transform the chip's protocol capabilities into a mass-producible, testable, and reliably deliverable RF subsystem. The chip provides "what it can do," while the module determines "how much it actually accomplishes." III. Engineering Parameters and Scenario Adaptation Analysis of O2072PM/PB The O2072PM and O2072PB modules designed by Qogrisys based on the Qualcomm QCC2072 (FastConnect C7700) platform correspond to the engineering constraints of the aforementioned FTTR/gateway scenarios in terms of parameters . In terms of RF capabilities , the O2072PM supports the IEEE 802.11be standard, 2×2 MIMO, and tri-band 2.4/5/6GHz concurrent operation. The 6GHz band channel bandwidth can reach 320MHz , achieving a peak rate of 5.8Gbps with 4096-QAM modulation . This rate level provides ample margin in current FTTR gateway designs, matching fiber backhaul bandwidth and reserving scheduling space for multi-user concurrent scenarios. In terms of latency control , the O2072PM supports 320MHz Enhanced Multi-Link Single Radio (eMLSR) . eMLSR, in engineering terms, means that in a single-radio hardware architecture, it uses an auxiliary radio (Aux Radio) to monitor the status of multiple frequency band links, quickly switching to a backup link when the primary link encounters interference or congestion, without undergoing a complete scan-association process . Qualcomm describes Aux Radio in its technical documentation as "automatically shutting down or waking up the primary radio by monitoring the TX/RX status," while also performing low-latency background scanning to reduce the impact of scanning on throughput . For cost-sensitive and space-constrained design scenarios such as FTTR sub-routers, eMLSR provides a feasible path to achieve near-multi-radio latency performance on a single-radio architecture. In terms of power management , the independent listening mechanism of the Aux Radio allows the main radio to enter a low-power state when idle, and is only awakened when the auxiliary radio detects a signal that needs to be transmitted or received. This mechanism has practical significance for the heat dissipation design and long-term operating power consumption of FTTR sub-routers—distributed networking means that multiple nodes are continuously online, and the cumulative effect of power consumption of a single node cannot be ignored. In terms of packaging , the O2072PM uses the M.2 2230 Key E standard interface, while the O2072PB is a 13×15mm surface-mount package . These two forms correspond to different overall hardware architectures: the M.2 interface is suitable for slot-based gateway/router products, while the surface-mount version is suitable for high-density onboard sub-routers or space-constrained FTTR slave gateways. This packaging option itself demonstrates engineering adaptability , as different OEMs' hardware platforms differ significantly in interface definitions, PCB space, and heat dissipation paths. Regarding platform compatibility , the O2072PM is compatible with Intel x86 platforms for kernel versions 5.15.24+, 6.1.99, and 6.12.0, and also has V1 compatibility with OpenWrt . This information is valuable for OEMs in their selection process: the maturity of driver compatibility directly impacts product development cycles and post-mass production stability risks . Mature compatibility with Linux platforms means that gateway solutions based on x86 or ARM Linux can complete RF subsystem debugging in a shorter time, while OpenWrt compatibility provides a foundation for customized routing/gateway products. IV. The Value Position of the Module Segment in the Industry Chain According to IIM Information's "Global and China WiFi Module Market Analysis and Survey Report," the global Wi-Fi module market size is projected to reach US$16.82 billion in 2026 , with Wi-Fi 7 module shipments expected to climb to 17.2% , reaching approximately 234 million units for the year. IndexBox's market analysis further indicates that Wi-Fi 7 modules have a 40% to 70% price premium compared to their predecessors , and high-end modules (tri-band, 320MHz, 16+ spatial streams) are priced between US$250 and US$1500 . This pricing structure reflects an industry reality: the added value of the module segment largely depends on its "conversion efficiency" to chip capabilities . The same Wi-Fi 7 chip can exhibit significantly different RF performance, heat dissipation characteristics, power consumption curves, and driver compatibility in designs from different module manufacturers. As a carrier-grade product, FTTR gateways have higher requirements for long-term operational stability, environmental adaptability, and batch consistency than consumer-grade products. When selecting module solutions, OEMs focus not only on "Wi-Fi 7 support" but also on "whether the nominal performance can be stably reproduced under mass production conditions." From a supply chain perspective, Qualcomm's QCC2072 provides the foundational capabilities for the protocol layer as a chip platform, while module manufacturers focus on RF front-end matching, antenna design coordination, power management optimization, driver adaptation and verification, and engineering implementation for different package types. The value of this layer lies not in the chip definition stage, but in the product realization stage. V. Conclusion: Module Selection Logic in Centralized Procurement Scenarios The successful procurement of home gateways by China Telecom and China Mobile in 2026 marks the official launch of large-scale deployment of Wi-Fi 7 in operator home network terminals. The distributed architecture of FTTR and the product requirements for carriers impose engineering constraints on radio frequency modules that differ from those on consumer-grade routers. In a supply chain system driven by centralized procurement, the competitiveness of a module solution depends on the comprehensive performance of three dimensions: protocol compatibility with FTTR scenarios, hardware adaptability across multiple packaging forms, and driver maturity under the Linux/OpenWrt platform. The O2072PM's eMLSR implementation, Aux Radio power management, and tri-band 320MHz capability technically address the core needs of FTTR sub-routers and home gateways; its M.2 and surface-mount dual packaging forms cover the hardware architecture choices of different OEMs; and its Intel x86 and OpenWrt driver adaptation provides a verifiable starting point for complete system development. The transmission cycle of operator centralized procurement dictates that OEMs' module selection decisions often occur during the solution design phase before the procurement announcement. Within this time window, module solutions with a complete RF parameter system, multiple packaging options, and verifiable driver adaptation records occupy a more advantageous position in OEMs' technical evaluations .  

In the first half of 2026, China's newly connected photovoltaic (PV) capacity reached 71.77 million kilowatts, of which distributed PV accounted for 42.22 million kilowatts, or approximately 58.8%. Globally, according to the "Global and China Distributed PV System Market In-Depth Research and Consulting Analysis Report (2026)" released by IIM Information, as of the first half of 2026, the global cumulative installed capacity of distributed PV had exceeded 480 GW, with the Asia-Pacific region contributing more than 55% of the increase. It is projected that by the end of 2026, the global annual new installed capacity will reach between 98 GW and 115 GW, representing a year-on-year increase of approximately 12% . The large-scale production of distributed photovoltaics is propelling PLC (Power Line Carrier Communication) modules into a certain incremental market. This certainty stems from the convergence of three factors: mandatory policy support, the uniqueness of the technological path, and the completion of commercial validation. I. Policy-driven: Component-level safe shutdown becomes a global mandatory requirement The core application scenarios for PLC modules in the photovoltaic field are module-level rapid shutdown and module-level monitoring. These two functions are directly driven by mandatory standards in major global markets. In the North American market, NEC 2026 further revised the fast shutdown requirements of Article 690.12. According to SurgePV's NEC 2026 Fast Shutdown Compliance Guide, the 2026 version of NEC retains the existing voltage limit targets: conductors outside the array boundary must be reduced to no more than 30V within 30 seconds, and conductors inside the array boundary must be reduced to no more than 80V within 30 seconds or use certified PVHCS equipment . This means that each photovoltaic module needs to be equipped with a shutdown device with PLC communication capabilities. In the European market, the EN50065-1 standard clearly specifies communication equipment applicable to the frequency range of 3kHz to 526.5kHz on low-voltage power lines. Its typical applications include DC bus communication between photovoltaic panels and inverters in photovoltaic power generation systems. In the Chinese market, the new national standard GB/T 34932-2025 officially came into effect on April 1, 2026. Under the "four requirements" for dispatching, it mandates that new grid-connected equipment must support standard interfaces, collect data at a frequency of no less than one point every five minutes, and enforce identity authentication, data encryption, and access control. In 2026, the EU carbon tariff adjustment mechanism enters the mandatory compliance phase. Traditional inverter-level monitoring cannot meet the accuracy requirements for component-level carbon footprint tracing, making component-level power electronics and intelligent monitoring a crucial technological path for obtaining accurate carbon emission data . The core policy shift is that PLC communication modules are transforming from "optional accessories" in photovoltaic systems into "compliance necessities." Whether it's North America's rapid shutdown, Europe's module-level monitoring, or China's "four capabilities," all require reliable data communication links between module-level devices. II. Technology Adaptation: Why PLCs are Irreplaceable in Photovoltaic Applications The physical structure of a photovoltaic system dictates the choice of communication scheme. Each photovoltaic panel is connected to a DC power line, and each inverter is connected to the grid via an AC power line. PLC communication can fully reuse existing power lines for data transmission, eliminating the need for additional communication cables or wireless access points. Metal roofs and complex electromagnetic environments pose significant challenges to the reliability of wireless communication, while PLCs, using power lines as the physical medium, possess strong anti-interference capabilities. Although RS485 bus solutions offer reliable communication, they require additional communication cabling within the photovoltaic array, increasing installation costs, construction time, and potential points of failure. In photovoltaic module-level shutdown and monitoring scenarios, PLCs offer virtually no equivalent alternatives. III. Commercialization Validation: From Technology Introduction to Mass Shipment The photovoltaic PLC module market has completed the crucial leap from "technology verification" to "mass shipment. " PLC chips have achieved mass production in the photovoltaic module-level power electronics field , and module-level shutdown devices and power optimizers with built-in PLC modules are being exported in bulk to overseas markets such as Southeast Asia, and are widely used in residential and commercial distributed photovoltaic scenarios. This large-scale market achievement demonstrates that PLC communication technology has undergone long-term operational verification in the complex electromagnetic environment of the photovoltaic DC side, maintaining a high level of communication online rate . From a market perspective, each GW of photovoltaic power requires approximately 2 million photovoltaic panels. If each panel is equipped with one shutdown chip, the global annual demand exceeds 400 million panels. Currently, North America and Europe have mandated that distributed photovoltaic projects have module-level rapid shutdown capabilities. If China introduces similar mandatory standards, it will bring an even larger volume of incremental demand. IV. Photovoltaic Scenarios Solution for Qogrisys PLC Modules Qogrisys has established a clear product portfolio in the PLC module field, with both the S130N-ISI and 3121N-H modules being officially listed as recommended solutions for photovoltaic communication scenarios . S130N-ISI: A compact solution for shutdown and optimizer The S130N-ISI is based on the Leadcore VC6330 chip design, integrating a 32-bit ARM Cortex-M3 MCU and a 32-bit DSP, embedded Flash, 1MB SRAM, and rich communication interfaces. The module uses an LCC package, measuring only 20.6×12.6×2.5mm, and features an integrated on-chip wire driver, low power consumption, strong noise immunity, and an operating temperature range of -40°C to +85°C . This module supports dual communication protocols: China SGCC Q/GDW 11612 and IEEE 1901.1, and supports BPSK, QPSK, and 16QAM modulation . The S130N-ISI's ultra-small size and low power consumption make it suitable for integration into space-constrained photovoltaic (PV) shutdown devices or power optimizers. These shutdown devices are powered by the PV panels themselves and need to continuously monitor PLC signals on the power line at microwatt-level power consumption; the S130N-ISI's low-power design aligns with this requirement. 3121N-H: Multi-node networking solution for component-level monitoring The 3121N-H is developed based on the HiSilicon PS0211 chip, operating in frequency bands of 0.5-3.7MHz and 2.5-5.7MHz. The protocol is based on a subset of the IEEE 1901.1 standard, with an application layer rate of 80Kbps, and is equipped with a 200MHz ARM Cortex-M3 processor. A single CCO supports up to 200 STA nodes , supports dynamic routing and multi-path automatic addressing, and a typical 200-node Layer 2 network can be formed within 10 seconds . The 3121N-H's multi-node networking capability adapts to the unified access requirements of multiple components and devices in distributed photovoltaic systems. In component-level monitoring solutions, the 3121N-H can serve as a PLC monitoring module within the component junction box, collecting voltage, current, and temperature data in real time and coupling it to the string via DC power lines. At the bus layer, this module can replace the traditional RS485 bus, enabling wireless bidirectional communication with inverters, data acquisition units, and cloud platforms. Conclusion Qogrisys has listed "new energy" as an independent application area, with its products clearly covering photovoltaic panels, photovoltaic inverters, energy storage, and charging piles. In scenarios such as smart streetlights, smart parking, and charging piles, Qogrisys'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 . Currently, Qogrisys is targeting emerging markets in Southeast Asia .
