Industrial Wi-Fi 7 will fail without smart planning and investment

Wi-Fi 7 is beginning to roll out across enterprise networks, promising better speed, lower latency, and increased capacity.

IDS-INDATA warns if industrial environment deployments focus only on access point upgrades, they are likely to face serious problems. The benefits of Wi-Fi 7 may never be fully realized without proper design, power planning, and infrastructure upgrades.

Most industrial facilities are not struggling because they lack Wi-Fi 7 support. The real issue is that many sites are built on ageing network infrastructure that cannot support modern wireless performance.

Outdated cabling, insufficient power delivery, and weak RF planning continue to cause the majority of performance failures.

According to IDS-INDATA, manufacturers who focus on next-gen features without first addressing these foundational gaps risk poor results and costly delays.

Charlie McRae, Systems Engineer at IDS-INDATA, said, “Good wireless design has always been the make-or-break factor in industrial deployments. You can have the latest standard, but if your signal can’t make it through a steel-clad factory floor or if devices aren’t properly segmented, performance and reliability will suffer.”

Cisco research indicates that current Wi-Fi 6E and Wi-Fi 7 applications often support video conferencing, IP voice, and replacing wired connections. These uses are typical of enterprise environments.

In industrial deployments, the future is heading toward more demanding applications. IoT sensors, automated production equipment, and time-sensitive monitoring systems require consistent and resilient wireless connectivity.

One of the most common problems is the continued use of Cat5 cabling and 1 Gb switches. These components cannot handle the throughput Wi-Fi 7 access points are capable of delivering.

When high-speed wireless traffic hits an underpowered wired backbone, performance degrades quickly. Even when the wireless signal appears strong, end users often experience delays, unstable connections, or poor data flow across the network.

McRae emphasized this challenge. “Too many teams assume upgrading access points equals upgrading security or speed. In reality, infrastructure readiness and wireless design are what make or break a deployment.”

Power delivery is also a growing issue. While not every Wi-Fi 7 access point needs PoE++ support, many high-end models do. Rugged access points installed in harsh environments may have greater energy demands due to multiple radios and environmental protection features.

Older switches often cannot supply the necessary power, which leads to degraded performance, shortened coverage, or full hardware failure.

In these cases, companies may be forced to pause installations or invest in last-minute hardware replacements. This adds cost and time to projects that were expected to streamline operations. A power audit early in the planning phase can prevent these types of setbacks.

RF design is one of the most difficult parts of industrial wireless deployments. Factories are often home to metal beams, large machinery, and other sources of potential interference.

Wi-Fi 7 precision

Wi-Fi 7 introduces access to the 6 GHz spectrum, which offers more channels and higher speeds, but also demands precision. Mistakes in RF planning often lead to dropped connections, slow roaming between access points, and unstable application performance.

Cisco reports that sensors and automation tools will be among the primary drivers of 6 GHz adoption in industrial contexts. These tools need low latency and high reliability, two outcomes that depend heavily on correct RF planning. Without proper environmental assessments and spectrum analysis, Wi-Fi 7 installations could well fall short.

Security is another area where expectations can mislead teams. WPA3 is required for Wi-Fi 7 certification, but that alone does not make a network secure. Many facilities will still need to support legacy clients using Wi-Fi 4 or 5. That backward compatibility creates potential vulnerabilities that attackers can target.

Advanced features like Multi-Link Operation introduce complexity that may not be fully understood by every operations team. Proper segmentation, continuous monitoring, and strict access control policies are needed to keep industrial networks secure. These safeguards require planning and oversight, not just feature checklists.

McRae explained, “It’s not just about installing access points. It’s about building a wireless ecosystem that’s future-proof, secure, and designed for the realities of industrial operations.”

Whether a company plans to stick with Wi-Fi 5 or move ahead with Wi-Fi 7, IDS-INDATA says the priority should always be on the fundamentals, such as modern cabling, capable switching hardware, sufficient power supply, accurate RF design, and strong network segmentation.

These steps may take time but they remain essential to long-term wireless performance in demanding environments.
