Qualité Module WiFi7 & Module HaLow Wifi Fabricant

The global smart street light market is undergoing a structural expansion. A report released by Research and Markets in January 2026 shows that the market is projected to grow from $35.6 billion in 2026 to $74.9 billion in 2030, representing a CAGR of 20.4%. Europe is accelerating the renovation of existing infrastructure driven by mandatory replacement policies, while emerging markets in the Asia-Pacific region are releasing incremental demand through urbanization. However, a overlooked fact is that market expansion does not equate to simpler communication solution selection. On the contrary, as the focus of renovation shifts from "new construction" to "existing infrastructure," the primary constraint on communication solutions changes from technical specifications to the question: "Can this road be dug?" The position of PLC (Power Line Carrier Communication) under this constraint is clear: the streetlights themselves are connected to the power line, the PLC uses the same cable as both a power supply and data channel, and the communication signal is transmitted along the existing line without the need for any additional communication cables. Europe: Policy mandates have created the most certain scenarios for upgrading existing PLC systems. Europe is the region with the strongest policy drive for smart street light upgrades globally. A 2026 report by Mordor Intelligence points out that the EU's Mercury Regulation 2024/1849 requires the complete phase-out of compact fluorescent lamps by December 2025 and linear fluorescent lamps by December 2026. These compliance deadlines directly triggered a surge in municipal tenders. Simultaneously, the EU requires the public sector to reduce energy consumption by 11.7% by 2030, transforming the transition to network-connected LED lighting from an "optional" to a "compliance necessity." The unique aspect of this policy window is that it targets "replacement of existing infrastructure" rather than "new construction." Many streetlights in Europe were installed decades ago, with intact power cables but missing communication cables. Adopting a solution requiring separate communication cabling would mean excavating or re-laying conduits along the entire route, resulting in unpredictable costs and time. The ability of PLCs to reuse existing power cables perfectly matches the policy's mandated time pressure with the construction constraints of upgrading existing infrastructure. German practice provides a reference: the LED upgrade of 48,000 streetlights in Munich, combined with adaptive dimming, reduced energy consumption by 93% during off-peak hours. For these types of projects, communication reliability is more important than bandwidth; the millisecond-level latency of PLCs and the engineering advantages of no-wiring are more significant than wireless solutions in this scenario. However, the European market also presents a strict cost scrutiny. Smart retrofitting costs between €300 and €500 per pole, while basic LED replacement only costs €150 to €200. This price difference means that the selection of PLC modules must withstand scrutiny regarding the question of "why not use wireless?" The answer lies not in technological superiority, but in the engineering certainty under existing wiring conditions : wireless solutions are affected by terrain and building obstructions in dense urban areas, requiring additional relay nodes in practical testing, while PLCs, assuming the power supply cable is intact, have a physically existing communication link.   China and Asia Pacific: Differences in PLC Positioning in Incremental Markets Data from China's smart light pole market presents a different picture. QYResearch statistics show that the global smart city light pole market sales reached approximately $412 million in 2025 and are projected to reach $796 million by 2032, representing a compound annual growth rate of 10.0%. Unlike Europe's "replacement of existing stock," China's growth is largely driven by new "multi-purpose" projects: light poles simultaneously serve functions such as lighting, monitoring, 5G micro base stations, and environmental monitoring. Communication solutions tend to favor fiber optic or wireless backhaul because the civil engineering of the light pole itself is already included, thus amortizing the marginal cost of laying separate communication cables. This means that the main opportunity for PLCs in the Chinese street lighting market lies not in "building new smart light poles," but in the niche scenario of "energy-saving retrofitting of existing road lighting." Many urban roads in China only have power cables in their lighting circuits, lacking communication lines. If only single-lamp control, dimming, and fault feedback are required, PLCs offer better engineering economics than rewiring. A study published in the 8th issue of *China Lighting Appliances* in 2026 points to this logic: traditional control modes are energy-intensive and difficult to maintain, while mainstream wireless communication solutions are easily affected by terrain obstruction in densely populated urban areas. PLCs, utilizing existing cables for data transmission, offer advantages such as low cost and reliable connection. The Southeast Asian market is in an earlier stage. In March 2026, Terengganu, Malaysia, installed the state's first 5G smart lamppost at the Kedebayan Market, integrating smart lighting, monitoring, environmental monitoring, and electric vehicle charging functions. These markets share common characteristics: real incremental demand, but projects are small-scale, budgets are fragmented, and there is a higher sensitivity to module costs than to brand premiums. In these markets, PLC modules are more likely to follow lighting solution providers overseas rather than independently building brand recognition.   The strategic position of the Qogrisys S130N-ISI in this landscape The product parameters of the S130N-ISI need to be understood within the context of the aforementioned market differences. It is based on the Leadcore VC6330, with an LCC package size of 20.6×12.6mm, supports both Q/GDW 11612 and IEEE 1901.1 protocols, and provides UART, PWM, GPIO, ADC, and SPI interfaces, integrating a built-in wire driver. According to official data from Leadcore regarding the VC6330 chip, application-layer communication rates can reach 1Mbps, with attenuation resistance exceeding 112dB, and a 99.99% communication success rate in actual projects. These parameters address the question of "whether it can be used," but the "usability" in different markets depends on the line conditions and system integration quality. The aging of the lines in European projects, the distribution of interference sources in Chinese projects, and the differences in construction specifications in Southeast Asian projects all affect the actual performance of the PLC. In street lighting scenarios, the value of the S130N-ISI lies not in promising "it will work immediately after installation," but in providing a hardware option that meets basic engineering requirements in three dimensions: protocol matching (Q/GDW 11612, IEEE 1901.1), size adaptation (20.6×12.6mm can be embedded in a single lamp controller), and interface integration (PWM dimming, ADC acquisition). One fact that requires careful consideration is that publicly available authoritative data on the actual global adoption rate of PLCs in smart streetlights is limited. What can be confirmed is that PLCs are one of the official options for smart streetlight connectivity, with academic research and engineering practice supporting their feasibility under specific conditions. However, conclusions such as "PLCs will dominate streetlight communication" lack data support. For engineering teams evaluating solutions, a more pragmatic approach is to test the wiring first, then select the modules. Only when the line impedance and signal-to-noise ratio are within reasonable ranges can the wiring-free advantage of PLCs translate into savings in construction time and costs; if test results are unsatisfactory, the costs of forcing PLC implementation may only become apparent during the commissioning phase.   Conclusion: The window of opportunity belongs to solution providers who clearly explain the "constraints". The global smart street light market's 20.4% CAGR provides a real window, but this window opens differently in different regions. In Europe, mandatory policies have created a definite demand for retrofitting existing infrastructure, where the wiring-free advantage of PLCs has the clearest engineering logic. In China, incremental growth is concentrated in the construction of new multi-functional light poles, where PLCs have opportunities in the energy-saving retrofitting of existing roads. In Southeast Asia, the early-stage market is testing the cost competitiveness of modules. In this context, the S130N-ISI isn't a "universal street light module," but rather a PLC hardware option that adapts to the needs of single-lamp controllers in terms of protocol, size, and interface. Its value lies not in the absolute values of its specifications, but in its compatibility with the specific project's wiring conditions. For the engineering team, this means resolving the "do we need to break the road?" question at the project initiation meeting, rather than discovering during the commissioning phase that line noise is causing communication success rates far below expectations. Testing the line first, then selecting the module—reversing this order might save you a quote, but cost you the entire road's commissioning time.  

I. The Real-World Coordinates of the Wi-Fi 8 Standard Progress Just two days ago, Qualcomm's Dragonwing platform released a signal at Network X 2026 – the Wi-Fi 8 gateway solution was launched. To understand this, we need to clarify the current standard stage of Wi-Fi 8. At the IEEE plenary meeting in Montreal in July 2026, the 802.11bn task force voted to submit Draft 2.0 to the working group for a vote, thus finalizing the core features of Wi-Fi 8. According to the timeline disclosed by ABI Research, Draft 3.0 voting is scheduled for January 2027, Draft 4.0/initial standards association voting is targeted for May 2027, final working group approval is set for March 2028, IEEE standards committee approval is expected for May 2028, and the Wi-Fi Alliance certification program is expected to launch in January 2028. The key implication of this timeline is that Wi-Fi 8 will still be in the draft standard stage in 2026, with certified products and large-scale commercialization not truly starting until 2028. However, chip platform and module solution providers have already significantly accelerated their product development pace. Broadcom was the first to release Wi-Fi 8 chipsets in October 2025, followed by MediaTek and Qualcomm. By September 2026, the Wi-Fi Alliance had already held its first Wi-Fi 8 pre-certification interoperability Plugfest in Beijing, Taipei, and California. While the standard has not yet been finalized, the industry's engineering preparations are already in full swing. II. The Differentiated Deployment Logic of Qualcomm's Dragonwing Platform Qualcomm's Dragonwing product portfolio, showcased at Network X 2026, presents a clear market segmentation strategy. designed for mainstream fiber broadband gateways . According to Qualcomm's official product briefing, the F8 integrates Wi-Fi 8 connectivity and native PON architecture support, targeting Home Gateway Units (HGUs) and Single Units (SFUs). Key specifications include: peak wireless capacity of 23Gbps, support for up to 750 concurrent clients, up to three-band operation and a 14-antenna configuration , flexible RF configuration allowing for a 5x5 mode or splitting into dual-band simultaneous 2x2+3x3 modes, and native support for GPON, XG-PON, and XGS-PON standards. The platform supports open-source middleware such as prplOS, OpenWRT, RDK, and OpenSync, and is equipped with a dedicated scanning radio frequency for automatic channel selection and radar detection. designed for high-end enterprise access points (APs) and flagship home routers . Its specifications are significantly improved: peak wireless capacity of 33Gbps, support for up to 1500 concurrent clients, up to five frequency bands and a 20-antenna configuration , integrated five-core CPU and Hexagon NPU, and support for edge AI inference. Developed in collaboration with GFiber, this platform, a Wi-Fi 8 Premium Gateway, aims to support symmetric 20Gig broadband services, redefining the gateway from a "connected device" to a "smart service platform." Meig Smart chose to launch its Wi-Fi 8 gateway solution on the N8 platform, officially announcing it at Network X 2026 on October 14th. The industry significance of this launch lies in the fact that the entire engineering transformation chain of a Wi-Fi 8 gateway, from chip platform to deliverable solution, has been fully demonstrated for the first time. For downstream customers, the Wi-Fi 8 gateway is no longer a distant concept "waiting for the standard to be finalized," but rather an evaluable chip base and a referenceable solution design. III. Generational Positioning of Qogrisys Gateway Module Product Line Although manufacturers are currently rushing to implement their strategies in advance, WiFi 7 and WiFi 6 remain the mainstays of shipments. They are more mature than WiFi 8 and are still the preferred choice. During this window of opportunity before the Wi-Fi 8 standard is finalized, gateway module solution providers need to strike a balance between technological foresight and market deliverability in their product strategies. Qogrisys's two main gateway module products are precisely designed to meet different levels of demand during this transition period. Wi-Fi 7 Platform: O2072PM and O2072PB The O2072PM is based on the Qualcomm FastConnect C7700 (QCC2072) chip, uses a standard M.2 Key E interface (22×30mm), and supports Wi-Fi 7 (802.11be) and Bluetooth 6.0. Its core capabilities include: tri-band 2.4/5/6GHz concurrent operation; the 6GHz band supports 320MHz channel bandwidth and 4096QAM modulation, with a peak rate of 5.8Gbps ; and it supports 320MHz Enhanced Multi-Link Single Radio (eMLSR) , enabling millisecond-level switching when the link is interfered with. This module has completed driver adaptation for Intel x86 platforms with kernels 5.15.24+, 6.1.99, and 6.12.0. The O2072PB is based on the same QCC2072 chip and uses a 15×13mm surface mount package, targeting space-constrained onboard integration scenarios. Wi-Fi 6E Platform: O2066PM and O2066PB The O2066PM is based on the Qualcomm QCA2066 chip and uses a standard M.2 2230 Key E interface (22×30×2.7mm), supporting Wi-Fi 6E (802.11ax) and Bluetooth 5.2. Key specifications include: tri-band 2.4/5/6GHz support, dual-band simultaneous (DBS) operation, and a maximum speed of 2975.6Mbps ; support for 2×2 MU-MIMO, 160MHz channel bandwidth, and dynamic frequency selection (DFS radar detection). The Bluetooth interface supports both UART/PCM and USB configurations. The module operates in a temperature range of -30℃ to +85℃ , exhibiting industrial-grade stability. In VR products, it has achieved a measured throughput of 2.1Gbit/s and has been designed into customer VR products, which were showcased at CES 2023. The O2066PB is based on the same QCA2066 chip, and its core capabilities are identical to the O2066PM; the difference lies in its package form. It uses a small SMT LGA package, measuring 13×15×2.3mm , targeting space-constrained onboard integration scenarios. Wi-Fi uses a PCIe interface, and Bluetooth uses a UART/PCM interface. Its operating temperature range is -30℃ to +70℃ , making it suitable for consumer-grade terminal devices. the O2072 series is logically consistent with the "high reliability connection" emphasized by Wi-Fi 8—Wi-Fi 7's MLO provides an engineering implementation of link redundancy, while Wi-Fi 8's Multi-AP Coordination (MAPC) extends the coordination scope from a single device to a multi-node network. The O2066 series represents another path: during the transition period when the cost of Wi-Fi 7 modules has not yet dropped to an acceptable level for low-end and mid-range gateways, Wi-Fi 6E's 6GHz band capability provides cost-sensitive customers with a "partial generational upgrade" option . IV. Generational Transition Logic Between Chip Platforms and Module Products From Wi-Fi 6E to Wi-Fi 7 and then to Wi-Fi 8, the technological evolution path of gateway modules shows a clear continuity. The core improvement of Wi-Fi 8 over Wi-Fi 7 lies not in peak speed . According to industry technical analysis, Wi-Fi 8 is compatible with Wi-Fi 7's 2.4/5/6GHz tri-band, 320MHz channel, and 4096QAM. Existing Wi-Fi 7 RF architectures can support these core features through firmware upgrades . Wi-Fi 8 offers approximately double the actual throughput and reduces P99 latency to about one-sixth of Wi-Fi 7. Its core value lies in reliability, coverage, and concurrency efficiency in high-density/long-distance scenarios , achieved through multi-AP collaboration, dynamic resource scheduling, and enhanced link design. Wi-Fi 7 addressed "speed," while Wi-Fi 8 addresses "stability." The eMLSR multi-link operation capability and tri-band concurrent architecture already possessed by the O2072 series from Qogrisys are engineering implementations on the Wi-Fi 7 platform. As the Wi-Fi 8 MAPC protocol stack and enhanced long-range response (ELR) features mature, module products based on the Wi-Fi 7 RF architecture have the engineering foundation to migrate to Wi-Fi 8 features at the hardware level . The core challenges lie in upgrading the software protocol stack and implementing multi-AP coordination functions. The O2066 series represents another path: during the transition period when the cost of Wi-Fi 7 modules has not yet dropped to an acceptable level for low-to-mid-range gateways, the 6GHz band capability of Wi-Fi 6E provides cost-sensitive customers with a "partial generational upgrade" option . V. Conclusion Qualcomm's Dragonwing platform was publicly launched as a Wi-Fi 8 gateway solution during Network X 2026, marking the transition of Wi-Fi 8 from the standard draft and chip prototype stages to the gateway product engineering stage . Meig Smart's solution release validates the transformation path from chip platform to deliverable gateway, and also indicates that the competitive pace among module solution providers has shifted from "following after the standard is frozen" to "parallel development during the standard draft stage." For gateway module solution providers, the core task at this stage is not to "get a head start" on the Wi-Fi 8 platform, but to accumulate transferable engineering capabilities on the Wi-Fi 7 and Wi-Fi 6E platforms. The experience of O2072PM / O2072P B in eMLSR multi-link operation, the accumulated RF engineering expertise in tri-band concurrent architecture, and the cost optimization path of O2066PM / O2066P B in the 6GHz band together constitute the product positioning for the transition to the Wi-Fi 8 era. From a longer-term perspective, Wi-Fi 8 redefines the gateway from a "wireless coverage device" to an "access node in a multi-AP coordinated network." This role change requires module solution providers to extend their capabilities beyond simple RF engineering and driver adaptation to system-level capabilities such as network topology planning, multi-node collaborative scheduling, and deployment scenario adaptation. During the standard window of 2026-2027, module solution providers' product strategies need to find a balance between "technological foresight" and "current deliverability"—Wi -Fi 7 modules serve current high-end gateway needs, Wi-Fi 6E modules cover cost-sensitive scenarios, and Wi-Fi 8 productization preparation needs to be quickly integrated as soon as the chip platform becomes available.  

I. La logique d'acceptation a changé: de "qu'il soit installé ou non" à "seulement si il est testé". Les projets photovoltaïques sur les toits de Shenzhen subissent une mise à niveau substantielle des normes d'acceptation.qui définit des indicateurs quantitatifs précis pour l'arrêt rapide: l'action d'arrêt doit être terminée en 30 secondes au plus, la tension dans un rayon d'un mètre du réseau photovoltaïque doit descendre en dessous de 80V,et la tension à l'extérieur de 1 mètre devrait tomber en dessous de 30V. Ce n'est pas quelque chose qui peut être simplement rejeté comme "installer un arrêt rapide". Le personnel d'accueil sur place va d'abord localiser tous les points de déclenchement de l'arrêt,confirmant la cohérence de la logique des sorties d'incendie, près de l'onduleur et au terminal de télécommande; ensuite vérifier la correspondance entre les dispositifs d'arrêt et les composants; enfin,enregistrer l'heure et la tension aux points de mesure spécifiés dans les dessins, confirmant que la limite du tableau, à l'intérieur comme à l'extérieur de la version adoptée du projet, satisfait aux exigences.Le simple fait de déclarer "la DRS est inscrite dans la facture de matériaux" n'est plus suffisant pour l'acceptation; la performance de contrôle de tension au niveau du système est le critère final. La norme du groupe de Shanghai T/ESETA 0000072026 a encore affiné les exigences: l'arrêt doit être terminé dans les 30 secondes suivant le déclenchement,et la tension externe de la limite atteignable doit être ≤ 30V, la tension interne doit être ≤ 120 V et la puissance de sortie ≤ 1 W. Elle indique également clairement que "l'arrêt est divisé en niveau composant et niveau chaîne,Les solutions à l'échelle des composants devraient être privilégiées dans les zones densément peuplées. " Le marché nord-américain a des barrières d'entrée plus strictes.et que la protection contre les chocs électriques pour les pompiers à l'intérieur de la limite doit être obtenue par un dispositif PVHCS ou une méthode de limitation de tension inscrits sur la liste.Lors du choix d'une solution PLC, la méthode de modulation de la puce et l'immunité au bruit déterminent directement le nombre de composants que le système peut prendre en charge. II. La logique hiérarchique de SunSpec: Conformité des puces ≠ Certification du module ≠ Approbation complète du système Il s'agit d'une question critique qui est le plus facilement négligée par les fabricants de commutateurs et les acheteurs de modules. La spécification de l'alliance SunSpec "Signal de communication pour l'arrêt rapide" définit le protocole de communication entre l'émetteur et le récepteur:l'émetteur envoie continuellement un signal dans un état "opérationnel"L'Alliance SunSpec déclare explicitement:"Seule la marque "SunSpec Certified" prouve la mise en œuvre complète et réussie de la spécification de fonctionnalité de signal de communication SunSpec Rapid Shutdown.Les déclarations de "conformité SunSpec" ou de "compatibilité SunSpec" faites par les fabricants ou d'autres tiers ne sont pas équivalentes à un certificat délivré par SunSpec.. " Cela signifie queLa prise en charge des puces pour les protocoles, le passage des tests de conformité des modules et la certification complète des dispositifs sont trois niveaux de vérification indépendants. La compatibilité des protocoles au niveau des modules n'est que le premier obstacle; les certifications de sécurité telles que UL 1741 et CSA C22.2 au niveau de l'ensemble de l'unité sont les passeports d'entrée sur le marché.Cette compréhension est cruciale pour les décisions de sélection des fabricants de disjoncteurs.   III. Trois dimensions d'ingénierie pour la sélection des modules: taille, consommation d'énergie et capacité de réseau Pour les fabricants de disjoncteurs, les caractéristiques "support PLC" et "conducteur de ligne intégré" sur les spécifications de la puce ne sont que le point de départ.Ce qui détermine vraiment si une solution peut être produite en série et mise en œuvre, c'est l'adaptabilité de l'ingénierie au niveau du module. La première dimension est la taille.L'interrupteur est installé sur le panneau arrière de chaque module photovoltaïque, où l'espace est extrêmement limité, et il partage cette zone limitée avec les boîtes de jonction et les câbles.La taille de l'emballage du module détermine directement l'espace de conception et la méthode d'installation du boîtier du disjoncteur. Les modules PLC utilisant le chipset Hisilicon PS0211 utilisent généralement un boîtier d'en-tête de broche de 28,12 × 18,00 mm ou un boîtier de doigt en or de 20,0 × 14,2 mm,Certains fabricants de modules ont lancé une version miniaturisée de 20.0 x 11.0 mm. La deuxième dimension est la consommation d'énergie.Le dispositif d'arrêt est alimenté par le panneau photovoltaïque lui-même et n'a pas d'entrée de puissance indépendante.État non expéditeur de colis), et la puissance de fonctionnement dynamique est ≤ 0,5 W. Pendant les périodes d'insuffisance de la lumière du soleil, lorsque les modules sont ombragés ou la nuit,le module doit compter sur une consommation d'énergie en veille extrêmement faible pour maintenir sa capacité de surveillance;, en attendant le signal "opération autorisée" envoyé par l'émetteur de l'onduleur. La troisième dimension est la capacité de mise en réseau.Les signaux PLC sont transmis par des lignes d'alimentation en courant continu, et le dispositif d'arrêt, agissant comme un nœud STA, doit établir un lien de communication fiable avec le CCO à l'extrémité de l'onduleur.La solution HiSilicon PS0211 prend en charge la mise en réseau rapide en 10 secondes dans un nœud typique de 200, scénario de réseau à deux niveaux, prenant en charge le routage dynamique et l'adressage multi-path, et les méthodes de propagation des commandes unicast, multicast et broadcast.Pour l'exigence d'un accès unifié pour plusieurs composants et dispositifs dans les systèmes photovoltaïques distribués,l'échelle de mise en réseau et les performances en temps des modules ont une incidence directe sur l'efficacité de mise en service du système. IV. Alignement de scène de deux modules PLCQuogrisysy Dans la sélection des modules PLC photovoltaïques d'arrêt, Qogrisysy fournit deux produits basés sur différentes solutions de puces, chacune correspondant à des axes d'ingénierie différents. le système S130N-ISI (solution VC6330 de Linktronics)Ce module utilise un emballage LCC, avec une taille de PCB contrôlée à 12,6 × 20,6 × 2,5 mm.Il fonctionne à des températures allant de -20°C à 80°C et à des températures de stockage de -40°C à 125°C, prenant en charge la bande passante SGCC de 0 à 12 MHz et le protocole de communication IEEE 1901.1.Pour les conceptions d'appareils de commutation dont l'espace est extrêmement limité, la taille physique du module est souvent le premier obstacle de dépistage. Pour la conception des boîtiers des unités d'arrêt rapide (RSU) où l'espace est sévèrement limité, les dimensions physiques du module servent souvent de critère de sélection principal.,La compatibilité technique au niveau du module est plus critique que les paramètres spécifiques de la puce:l'appareil est monté à l'arrière du module photovoltaïque dans une zone d'espace extrêmement limité et est alimenté par le panneau photovoltaïque lui-même, ce qui l'oblige à surveiller en permanence les signaux PLC lorsqu'il fonctionne à un niveau de consommation de puissance de microwatts.L'efficacité et la fiabilité sur une large plage de températures détermine directement si l'unité RSU complète peut fonctionner de manière stable dans des environnements de toit réels.. V. Conclusions clés Tout d'abord, les PLC sont la solution technique optimale pour l'arrêt rapide au niveau des composants.La spécification SunSpec utilise explicitement des PLC comme porteur de signal de communication, multiplexant les lignes de courant continu pour transmettre des signaux de contrôle,évitant ainsi les risques de coûts et de fiabilité liés à la pose de lignes de communication séparées pour chaque composant. Deuxièmement, les critères d'acceptation passent de "fonctionnalité" à "efficacité mesurable".Les spécifications de 30 secondes/80V/30V de la SJG 220-2026 et les exigences quantitatives de la norme du groupe de Shanghai signifient que la conception d'une solution d'arrêt rapide doit résister à des essais sur place. Troisièmement, la principale considération pour la sélection du module devrait passer des "paramètres de la puce" à "adaptabilité de l'ingénierie".Les trois indicateurs d'ingénierie: contraintes d'espace de l'unité d'arrêt, contraintes de consommation électrique dans des conditions d'autoalimentation,Les restrictions de l'échelle du réseau dans les scénarios distribués sont essentielles pour déterminer si une solution peut être produite et mise en œuvre en série.. Quatrièmement, la connaissance des niveaux de certification est une capacité que les fabricants de disjoncteurs doivent mettre en place.La prise en charge de la puce pour le protocole SunSpec, la certification du module par SunSpec et la certification complète de l'unité par les normes de sécurité UL 1741 sont trois niveaux de vérification indépendants.La puce Hisilicon PS0211 indique explicitement le support pour la norme SunSpec, et le module Qogrisysy 3121N-H, basé sur cette puce, fournit une garantie fondamentale au niveau du protocole pour la certification complète des unités des fabricants de disjoncteurs. Cinquièmement, le rôle des fournisseurs de modules passe de la "livraison de dispositifs" à l'"assistance à la certification".Les fabricants de commutateurs ont besoin de plus que de simples "modules utilisables"; ils ont besoin de partenaires techniques qui peuvent "aider à comprendre la logique des tests SunSpec, optimiser la conception des réseaux système,et aider à réussir la certification globale du système. "
