From basic connectivity to always-on: evolving Wi-Fi technology reshapes device design

With Wi-Fi 7 and 6 GHz WLAN, high-speed wireless connections have moved from nice-to-have to essential. Homes rely on smooth streaming, gaming and smart devices, while offices and campuses depend on Wi-Fi for video meetings and cloud tools.

To keep up, Wi-Fi Network devices run at higher power, pack in more antennas, and adopt more compact designs. Thermal load and design complexity rise together, turning housing material into a key lever to achieve stable performance and long-term reliability.

As Wi-Fi 7 reshapes how we connect at home and at work, managing heat is becoming increasingly critical to achieve advanced and reliable connectivity.

With our innovative thermal conductive material solution and strong technical capabilities, we aim to help our partners build next-generation Wi-Fi solutions ready for the continuous evolution of network infrastructure.

Efficient thermal performance without signal interference for stable high-speed Wi-Fi

High-performance processors and dense power electronics in Wi-Fi 7 devices generate considerable heat during continuous operation. Limited space and compact layouts make it harder to dissipate the heat away from sensitive components and keep temperatures within safe limits.

Our innovative thermal-conductive polycarbonate solutions provide efficient heat dissipation performance, that can be applied across different scenarios: 

Scenario I: Compared with common non-thermal conductive plastics for Wi-Fi Router housing, our solution offers a significant boost in heat dissipation, helping maintain lower operating temperature in compact designs.

Scenario II: Compared with conventional design using aluminum die-cast housing or heat sink, our solution can deliver comparable good heat dissipation performance based on optimized product structure and design. Meanwhile achieving full signal transparency without any interference.

Total Cost Optimization with simplified production and finishing

Replacing complex metal heat sinks with our thermal-conductive polycarbonate solution opens new ways of product design, greatly simplify the entire manufacturing process and achieve significantly optimized total cost. Injection-molded parts enable greater design freedom, along with high production efficiency and more streamlined assemblies by eliminating costly secondary processing steps such as painting, deburring, and others. This makes production becomes more faster, less resources-intensive and more economical.

Design Freedom and Aesthetic Flexibility for Customized Appearance

Next-generation Wi-Fi Routers need to deliver not only stable high-speed connectivity, but also visually align with diverse home and office environments.

Our thermal-conductive material solution enables sleek product design with good colorability including high quality white and surface finishes directly from molding. Also, it offers high impact resistance, together with good dimensional stability, and meets UL 94 V-0 thin-wall flame-retardant requirements.

Our innovative thermal conductive solution enables the blend of flexible design and versatile styling, to bring next generation Wi-Fi routers to life with both strong performance and eye-catching looks.

Value-added technical expertise beyond material to accelerate development cycle and time-to-market

Beyond material, we offer a full suite of in-house technical capabilities, from thermal simulation, feasibility analysis to mold design and product part design guidance, as well as on-site technical support.  The value-added offerings help customers shorten development cycles, reduce costly iterations, validate optimal thermal performance before production, and eventually bring reliable, high performance Wi-Fi Routers to market more efficiently.
