Dust flying from wall grooves, lengthy construction periods affecting operations, and high renovation costs… For a long time, the “difficulty of wiring” has been a stumbling block, deterring many hotel owners from upgrading to smart systems. Now, the large-scale implementation of PLC wired (power line communication) technology provides the “optimal solution”—a stable smart guest control system can be built without additional wiring. This “light renovation” solution has become a common choice for well-known hotel groups such as Atour, InterContinental, Qianxi, and Jinjiang, quietly rewriting the industry landscape of hotel intelligence transformation.
Core Breakthrough: “Transforming Power Lines into Network Lines” to Say Goodbye to Wall Drilling
The greatest advantage of PLC technology lies in its ability to achieve “transforming power lines into network lines” across domains, without additional wiring. Through advanced zero-crossing orthogonal frequency division multiplexing (Z-OFDM) technology, high-frequency data signals can be directly superimposed on the existing power lines of the hotel for transmission, truly achieving “dual-use of power and communication”.

Practical Value: Triple Upgrade in Efficiency, Cost, and Stability
In practical implementation, the advantages of the PLC wired smart guest control solution have been continuously validated, becoming a “weapon” for hotels to reduce costs and increase efficiency..
No Wiring Required, Reducing Wiring Costs: A certain hotel has a very high occupancy rate, and to avoid affecting normal operations and guest stays, renovations are carried out after guests check out, with completion before the next guest checks in, achieving efficient guest control renovations that are smart, fast, and stable. At the same time, the characteristic of not requiring additional wiring saves on wiring material procurement, wall repair, and other aspects, reducing the owner’s construction costs.
Simple Operation and Maintenance: The solution adopts PLC Mesh technology, allowing devices to be configured easily through a gateway, making it user-friendly and customizable according to the owner’s needs, with simple maintenance in the future.
Stable Communication: Through dedicated frequency division and error correction coding technology, information encryption is used to protect user privacy. PLC power line communication is as stable as wired communication, ensuring stable operation of smart devices in guest rooms..
Full-Scene Adaptation: From New Construction to Renovation, Balancing Operations and Experience
Whether it is the “pre-installation” layout of new hotels or the “post-installation” renovation of old hotels, PLC power line communication can achieve “seamless adaptation”. The InterContinental Hotel Group adopted this solution in its renovation projects for old hotels, maintaining a guest room operational rate of over 90% during the renovation period, avoiding business losses while quickly completing the smart upgrades of lighting, air conditioning, and curtains; Qianxi Hotels, on the other hand, created a “networked upon check-in” experience through the PLC system—when guests insert their room cards, the system automatically activates preset lighting brightness, air conditioning temperature, and curtain status for personalized scenarios, making the check-in experience more considerate; after renovation, a certain branch of Jinjiang Hotels saw a significant reduction in guest complaints about equipment failures, and annual operating costs were effectively controlled..

Green Empowerment: Energy Saving Aligning with Carbon Neutrality Trends
In the context of promoting the “green hotel” policy, the energy-saving benefits of the PLC solution are even more prominent. Through intelligent energy consumption management functions, hotels can monitor the electricity usage data of each guest room in real-time, dynamically adjusting device operations based on guest check-in/check-out status: automatically turning off non-essential high-power devices when guests are out, intelligently reducing air conditioning power during low usage periods… This not only aligns with the national “dual carbon” goals, but also effectively reduces overall energy consumption, truly achieving a win-win of “environmental protection” and “profitability”.
Industry Upgrade: Redefining Hotel Intelligence Renovation Standards
From budget hotels to high-end brands, PLC technology is driving the transformation of hotel intelligence from the traditional model of “heavy investment, long cycle” to a lightweight model of “low cost, high efficiency, light renovation. It not only meets the core demands of owners for “cost reduction and efficiency increase” but also aligns with consumers’ upgraded demand for “quality experience” and the national strategic promotion of “dual carbon goals”. In the future, as PLC technology becomes more widespread, it will no longer be just an “optional solution” for hotel intelligence but will become a “standard tool” for high-quality industry development—breaking through renovation bottlenecks with technological innovation, activating hotel vitality with lightweight upgrades, and providing guests with a smarter, more comfortable stay experience, while opening up a new track of “greening, intelligence, and efficiency” for the hotel industry.
