Rapid Progress in Multi-Technology Wireless Integration in the AI Era
Adam Smith began by examining the current state of the 5G market. Drawing insights from Mobile World Congress (MWC), he noted that telecom operators remain cautious about 6G adoption, largely due to the slow return on investment from 5G. However, the global 5G Fixed Wireless Access (FWA) market has emerged as a game-changer, delivering fast and cost-effective high-speed network deployment solutions. This trend continues to gain traction among service providers, driving growth in the 5G FWA Customer Premises Equipment (CPE) segment, which is projected to achieve a 31.5% CAGR from 2024 to 2032.
Meanwhile, the rise of Wi-Fi 7 and the upgrade cycle for mid-to-high-end networking equipment are fueling demand. With its significantly improved transmission speed and spectral efficiency, Wi-Fi 7 is accelerating the adoption of high-end routers in both residential and commercial environments. Market penetration is expected to exceed 10% in 2025, setting the stage for strong growth in 2026 and sparking anticipation for the upcoming Wi-Fi 8 standard.
In addition, the Industrial Internet of Things (IIoT) is creating new opportunities through the convergence of low-speed, long-range wireless technologies with Wi-Fi. Solutions such as 5G RedCap, Bluetooth, and UWB are experiencing heightened demand, serving as the true engine behind the dynamic wireless communication market. To ensure seamless integration and performance, verification and testing of these technologies are critical. LitePoint’s advanced testing solutions play a pivotal role in enabling continuous AI-driven innovation and delivering exceptional user experiences.
Wi-Fi 8: Ushering in an Era of "Ultra-High Reliability" Wireless Connectivity
James Lin, Deputy General Manager of the Connectivity Technology Development Division at MediaTek, was invited to share the technical highlights of Wi-Fi 8. Reflecting on the 25-year evolution of Wi-Fi technology, he noted that transmission speeds have increased thousands of times. However, Wi-Fi 8's focus has shifted beyond mere speed to "Ultra-High Reliability" and multi-device connectivity, aiming to deliver a more stable and lower-latency wireless network environment, providing users with a tangible upgrade.

James Lin highlighted four major innovations driving Wi-Fi 8:
Enhanced Long Range (ELR): ELR addresses the asymmetry in transmission power between routers and end devices, eliminating the “visible but unreachable” issue. MediaTek has integrated its proprietary MediaTek Long Range (MLR) technology into Filogic Wi-Fi 7 chips, achieving the extended coverage promised by ELR. This advancement enables the Dimensity 9400 mobile chip to maintain connectivity up to 30 meters on the 2.4GHz band.
Coordinated Spatial Reuse (Co-SR): By coordinating transmission power among routers, Co-SR optimizes time reuse and significantly improves Mesh network performance. MediaTek was first to implement Co-SR in its Filogic Wi-Fi 7 chips. In real-world Mesh topology tests, download speeds improved by 48%, while file download times dropped by 37.5%.
Dynamic Sub-Channel Operation (DSO): Addressing the mismatch between large bandwidth support in routers (5GHz or 6GHz bands) and smaller bandwidth support in most end devices, DSO optimizes router bandwidth efficiency through frequency hopping techniques. Simulation results show up to an 80% increase in overall network speed.
Non-Primary Channel Access (NPCA): NPCA leverages primary channel hopping to increase channel access opportunities, improving interference resistance and connection stability while maintaining compatibility with surrounding routers. Simulations show peak-hour speeds up by 67% and latency reduced by up to 92%.
James Lin emphasized: "Wi-Fi 8 aims to create a harmonious, high-performance network environment for multiple devices-offering speed, stability, and reliability. MediaTek remains committed to innovation, standard-setting, and delivering products aligned with the latest specifications. Our upcoming Filogic Wi-Fi 8 solution targets Wi-Fi 8 certification, streamlining partner product approvals and accelerating the industry’s transition to ultra-reliable connectivity."
As a global leader in wireless testing, LitePoint is dedicated to delivering precise RF testing solutions. The company will continue collaborating closely with MediaTek to validate Wi-Fi 8 technologies, ensuring exceptional chip quality and performance. Together, they aim to help the industry embrace a new era of ultra-reliable wireless connectivity-unlocking innovative applications and limitless possibilities.
