New Tech Tuesdays
Join Mouser's Technical Content team for a weekly look at all things interesting, new, and noteworthy for design engineers.
Wireless connectivity has become a critical part of modern factory automation. Factory floors increasingly rely on mobile equipment such as autonomous mobile robots (AMRs) and automated guided vehicles (AGVs), all of which require continuous network access. Production lines and workcells must also adapt as products evolve and equipment is reconfigured. At the same time, many factory devices generate large volumes of data that must be transferred reliably.
In this week’s New Tech Tuesdays, we examine how Wi-Fi® 7 technologies, such as Multi-Link Operation (MLO) and wider 6GHz channels, help address the throughput, latency, roaming, and reliability challenges of modern factory automation networks.
Wireless Performance in the Real World
Wi-Fi 7 implements technologies defined in IEEE 802.11be, including MLO. It also supports channel widths of up to 320MHz in the 6GHz band, subject to device capabilities, available spectrum, and regional regulations. With MLO, a compatible device is not limited to a single wireless link. Wider channels increase the amount of data that the network can carry.[1]
In March 2026, the Wireless Broadband Alliance reported results from enterprise testing of MLO. Under interference, uplink throughput improved by as much as 116 percent. The trials also showed a 66 percent reduction in uplink latency for real-time traffic.[2]
As manufacturers become more dependent on these connected systems, throughput alone is no longer an adequate measure of wireless performance. A fast connection is of limited use if interference, congestion, or roaming between access points introduces unpredictable delays. Likewise, coverage alone does not guarantee the performance these applications require. Network design must also account for congestion, interference, roaming, and traffic fluctuations across the factory floor.
Why Factory Wi-Fi Is Different
The factory floor presents unique challenges for wireless communication. Metal structures and machinery can affect how radio signals propagate through a facility, and wireless devices or industrial equipment may introduce interference. The radio frequency (RF) environment can change as equipment moves or production conditions change.[3] As a result, a wireless network that performs well in one location or under light traffic may behave very differently when production is running at capacity.
It is the factory’s dynamic nature that makes interference management and spectrum utilization increasingly important. Networks also cannot rely on users being static. An AMR moving through a factory may pass through the coverage areas of several access points, so maintaining communication depends not only on signal strength but also on how efficiently the client can transition between them.
MLO changes how compatible devices use available wireless links. Instead of relying on a single link, data can be transmitted across multiple frequency bands simultaneously, thereby increasing throughput and reducing latency.
The 6GHz band provides additional spectrum for Wi-Fi operation. Wi-Fi 7 supports channel widths of up to 320MHz. Wider channels allow more data to be transmitted at once, although their use depends on available spectrum and regional regulations. Access point and antenna placement remain critical considerations when planning the facility layout. Higher wireless data rates require suitable wired backhaul to prevent bottlenecks elsewhere in the network. As more operational data moves across the wireless network, security also becomes a critical part of network design.
The Newest Products for Your Newest Designs®
Bringing Wi-Fi 7 to the factory floor requires hardware designed for industrial installations.
The Advantech EKI-6333BE-4GD Industrial Wi-Fi 7 Access Point supports IEEE 802.11be operation across the 2.4GHz, 5GHz, and 6GHz bands. It also supports MLO, enabling compatible devices to use multiple wireless links as network conditions change.
For mobile applications, the EKI-6333BE-4GD supports IEEE 802.11r Fast Transition, which can reduce the time required for compatible clients to move between access points. This capability is particularly relevant to AMRs and AGVs that may travel through several coverage areas as they move around a facility.
The wired network infrastructure is equally important. Four 2.5GBASE-T Ethernet ports provide high-speed backhaul connectivity to the wider industrial network. The access point also supports Wi-Fi Protected Access 3 (WPA3)-Personal and WPA3-Enterprise security. The metal enclosure and wide operating temperature range of -40°C to +75°C make it well suited for demanding industrial environments. DIN-rail mounting and redundant 12VDC to 48VDC power inputs further support installation in industrial control environments.
Tuesday’s Takeaway
Inside a factory, wireless networks must maintain reliable connections even as equipment moves and conditions change across the production floor. Wi-Fi 7 gives network designers greater flexibility in using the available spectrum. For mobile equipment, Fast Transition can reduce the time spent transitioning between access points. Together, these features help address practical challenges that become increasingly important as factories connect more of their equipment to wireless networks.
