Networking in Healthcare:

Why Wi-Fi in Hospitals Is Harder Than You Think

Hospitals depend on connectivity as much as they depend on clinical expertise. From patient monitors to medication scanners, nearly every workflow now relies on a wireless network that must be fast, secure, and always on.

But hospital environments are among the most challenging places to design because of:

• Variety of devices: Thousands of endpoints — laptops, tablets, badge scanners, telemetry monitors, infusion pumps, and imaging systems — all need stable connections, often on different network tiers.
• Building complexity: Thick walls, lead-lined imaging rooms, and multiple floors with mixed materials can distort or block radio signals.
• Mobility and mission-critical traffic: Clinicians move constantly, and handoffs between access points must be seamless to avoid dropped connections during patient care.

In other words, designing hospital Wi-Fi isn’t like covering office cubicles — it’s a matter of patient safety and operational continuity.

IT vs. OT in Healthcare: A Delicate Balance

Healthcare technology spans two interconnected worlds: Information Technology (IT) and Operational Technology (OT).

• IT handles administrative systems such as the electronic health record (EHR), scheduling, and billing.
• OT covers the clinical and facility systems — from patient monitoring devices to building management sensors that control air pressure in surgical suites.

These networks have historically been separate, but the rise of connected medical devices (IoMT) and data-driven care is bringing them closer together.

That integration brings both opportunity and risk. As Advizex Solution Architect Jared Baber explains:

“You don’t want a bad day in the office to create a bad day in your hospital.”

Network segmentation is critical. Using models inspired by the Purdue Model for Industrial Control Systems, healthcare organizations can isolate and secure medical devices, while still enabling the data exchange needed for analytics, AI, and predictive maintenance.

Private 5G and Wi-Fi: A Connected Care Hybrid

Hospitals are starting to adopt hybrid networking that combines the reach of private 5G with the familiarity of enterprise Wi-Fi.

Private 5G can extend reliable connectivity across large campuses — from parking garages and ambulances to pop-up clinics and remote patient units. Think of it like your cell phone: even far from the tower, you can stream, call, and text. Inside a hospital, private 5G provides that same coverage with fewer radios and less interference.

Another advantage: network control. Private 5G limits what can connect, reducing “noisy” or unauthorized devices that might otherwise interfere with critical clinical traffic.

We’ve seen this model succeed in large regional systems and new specialty facilities, especially where mobility and reliability are non-negotiable.

Designing for Resiliency and Reliability

Hospitals never close, and neither should their networks. Yet many health systems rely on centralized IT teams that support multiple facilities across a region — sometimes states away. That makes reliability and remote management essential.

Selecting the right infrastructure is key:

• Hardened access points that withstand sterilization processes.
• Smart antenna placement for high ceilings and dense equipment areas.
• Automated monitoring tools to detect interference before it affects patient care.

Healthcare environments also demand rigorous redundancy — ensuring EHR systems, telemetry data, and communications continue even if a link fails.

The Future of Connected Care

As hospitals embrace AI, remote monitoring, and digital front doors, the network becomes the backbone of innovation. Connectivity enables everything from real-time clinical decision support to predictive analytics for equipment maintenance.

By blending Wi-Fi, private 5G, and strong IT/OT architecture, healthcare technology leaders can build networks that are fast, secure, resilient, and ready for what’s next in patient care.
