Wi-Fi is the foundation of every business system. From enabling cloud-based collaboration to powering applications, wireless connectivity supports nearly every aspect of business operations. For IT managers and technology leaders, ensuring reliable Wi-Fi performance is a business must.
Reflecting this priority, Cisco’s 2024 Global Networking Trends Report found that 42 percent of organizations cite upgrading Wi-Fi infrastructure for improved performance and density as their top initiative over the next two years—an acknowledgment that Wi-Fi interference and network congestion have become major obstacles to digital experiences.
Wi-Fi interference remains one of the most common and disruptive issues across workplaces. It compromises productivity, overall workflow in both the short- and long-term, and is a reoccurring challenge for the IT department. If left unresolved, these problems can result in decreased performance, increased helpdesk tickets, and a negative hit to business operations. With the right action plan, IT leaders can diagnose and eliminate interference, ensuring that their Wi-Fi becomes a strength.
Action Item #1:
Conduct a Wi-Fi Site Survey
A comprehensive Wi-Fi site survey is an integral action item that will pinpoint dead zones, measure signal-to-noise ratios, and identify frequency overlap or congestion. This is especially true in the crowded 2.4 GHz spectrum.
Whether surveying a small, open space or a large, multi-floor environment, Wi-Fi surveys provide benefits like:
- Optimized network performance: A Wi-Fi survey aids in pinpointing weak signals and areas, allowing for the most optimized placement.
- Improved capacity: A Wi-Fi survey can help maximize the capacity of the existing network, decreasing interference and increasing signal strength.
- Enhanced user experience: A Wi-Fi survey promotes the overall user experience, improving security, identifying interference, and increasing satisfaction.
Action Item #2:
Optimize Router Placement and Network Infrastructure
Start by conducting a physical audit of router locations—poor signals often stem from router placement. Positioning routers centrally and away from walls and electronic devices, such as a microwave, will help mitigate the disruption of the signal quality.
Even the smallest adjustments can significantly enhance performance. Testing with RF (radio frequency) analysis tools allow you to identify and understand weak coverage areas. For multi-floor or open-plan offices, upgrading to a mesh network could be a more suitable option, as mesh networks offer the advantages of reliable speeds and increased scalability.
Action Item #3:
Isolate High-Bandwidth Devices from Main Operations
Wi-Fi interference also results from congestion when too many devices compete for limited wireless bandwidth. Devices such as video conferencing systems and streaming displays consume excessive bandwidth, which can reduce performance for other users.
One way to fix this is to segment network traffic. When possible, migrate high-bandwidth devices to wired connections to alleviate traffic. Alternatively, isolate them on dedicated Virtual Local Area Networks or separate Wi-Fi Service Set Identifiers to reduce congestion on the primary business network.
Tip: An effective way to prevent downtime during working hours is to schedule large file transfers or backups during off-hours.
