Understanding the Shift to 6 GHz in Industrial WLAN
Spectrum congestion has long been a significant challenge for wireless industrial networks. Traditional spectrums such as 2.4 GHz and 5 GHz create limitations in providing the reliability needed for mission-critical applications. As industrial organizations often favor wired solutions due to these restrictions, the advent of the 6 GHz spectrum is a game changer. This new band, providing an additional 1200 MHz, promises to deliver the much-needed capacity that manufacturers have been seeking. The anticipated growth in industrial WLAN, illustrated by ABI Research, highlights an expected Compound Annual Growth Rate (CAGR) of 7.6% in ruggedized industrial WLAN AP shipments from 2024 through 2030.
Regional Variances in Industrial WLAN Growth
The growth of 6 GHz technology will not be uniform across regions. According to industry analysis, the United States, benefiting from a favorable regulatory environment for WLAN, is set to experience a dramatic increase in shipments of ruggedized industrial WLAN APs by 2030, expected to be 219% higher than in 2023. In stark contrast, mainland regions prioritizing 5G and 6G technologies, such as China, will see only modest growth in industrial WLAN, achieving a mere 7% increase in the same timeframe.
The Transition from Wi-Fi 4 to Wi-Fi 6
As of recently, the 802.11n standard, commonly known as Wi-Fi 4, continues to dominate the landscape of ruggedized industrial WLAN APs, accounting for 45.9% of all shipments. However, the rapid evolution of standards shows that shipments for ruggedized industrial WLANs featuring 802.11ax, or Wi-Fi 6, are projected to grow significantly, climbing from 0.82 million in 2024 to 1.41 million by 2026. This upward trend means that 802.11ax will become the leading standard, surpassing Wi-Fi 4 at an unprecedented rate.
Future Prospects for Wi-Fi 6 in the Industrial Sector
The industrial market holds unique characteristics, notably an enduring preference for 6 GHz-enabled 802.11ax APs, despite observing a general decline in enterprise adoption of this standard. Although 802.11be (Wi-Fi 7) is anticipated to emerge, industries remain cautious, often choosing to move directly from Wi-Fi 6 to Wi-Fi 8. This peculiar trajectory emphasizes the complexity of managing industrial WLAN networks and underscores the necessity for specialized support and guidance.
Challenges and Opportunities in Industrial WLAN Management
The industrial WLAN sector operates within its own set of rules, distinct from typical enterprise networking environments. Managed expectations amidst evolving standards pose challenges that necessitate expert guidance. With many organizations still navigating through legacy systems like Wi-Fi 4, the road to the adoption of newer technologies can be filled with hurdles. Therefore, it is crucial for industries to stay informed about developments in WLAN technologies to ensure strategic implementation that meets their specific connectivity needs.
The Need for Reliable Wireless Solutions
Given the rapid technological advancements and the increasing reliance on connectivity, industrial facilities are presented with an opportunity to modernize and capitalize on the benefits of wireless networking. The 6 GHz band will expedite this transition, providing the capacity that industries desperately require to support critical operations and seamless integration of wireless solutions. With a projected trajectory toward significant growth, industrial WLANs are on the verge of a transformative period.
