A practical guide for healthcare IT teams and infrastructure decision-makers
Most hospitals today run on Wi-Fi, and for good reason. It works, the clinical device ecosystem is built around it, and most IT teams know how to manage it. But with Wi-Fi 7 now available, private 5G gaining real momentum, and public 5G operators increasingly targeting healthcare, the question of what to invest in next is a legitimate one.
Getting the choice right is mostly about understanding your actual use cases and matching them to what each technology is genuinely good at. That’s what this article will try help you to do.
What each technology offers
Wi-Fi 6, 6E and Wi-Fi 7
Wi-Fi 6 (802.11ax) improved how access points handle many simultaneous devices, which matters a lot in clinical settings like wards and ICUs where dozens of devices share the same airspace. Wi-Fi 6E extended this by adding access to the lower 6 GHz band. In the EU, this means around 500 MHz of additional clean spectrum (5.925 to 6.425 GHz), a meaningful improvement for dense environments, even if it’s less than what is available in some other regions.
Wi-Fi 7 (802.11be), ratified in 2024 and now available in enterprise access points, is the most relevant upgrade for new hospital deployments. Its key improvement is the ability to use multiple frequency bands simultaneously, which reduces latency and makes the connection more resilient when one band is congested. Real-world latency in Wi-Fi 7 deployments is consistently lower than Wi-Fi 6, and the additional spectrum helps in high-density areas like operating theatres. It’s worth noting that some of Wi-Fi 7’s headline throughput figures assume access to the full 6 GHz band as available outside the EU. Within Europe, performance gains are still real and significant, but channel widths and peak throughput are constrained by the narrower spectrum allocation.
The one area where Wi-Fi still has a structural limitation is mobility. Moving between access points introduces a brief handover gap. Wi-Fi 7 handles it better than previous generations, but it’s not as seamless as what cellular networks provide for fast-moving devices.
Private 5G
Private 5G means building a dedicated mobile network on your own site, using licensed spectrum. You get a network that is entirely under your control, isolated from public traffic, and designed from the ground up for mobility and reliability. Handover between base stations is seamless by design, latency is consistently low even for moving devices, and you can separate different types of traffic into isolated network segments with guaranteed performance.
The trade-off is real. Private 5G is significantly more expensive to deploy than Wi-Fi, requires specialist expertise to manage, and the range of clinical devices with native 5G connectivity is still limited. It’s the right choice for specific, demanding applications, not a replacement for Wi-Fi across the board.
Public 5G
Public 5G from commercial mobile operators is a shared network, but its geographic reach is its defining strength. It works in ambulances, in patients’ homes, and anywhere along the care pathway outside your campus. Operators across Europe are increasingly offering dedicated service arrangements with agreed performance levels for healthcare applications, and whilst this is still an evolving commercial model, the direction of travel is clear.

Wi-Fi is the right answer for most indoor clinical use cases
Clinical workstations, Electronic Medical Records (EMR) access, nurse call systems, Voice over Internet Protocol (VoIP) handsets, imaging workflows and general staff devices all work well over Wi-Fi. These applications are not sensitive to brief handover gaps, and the device ecosystem expects it. Wi-Fi 7 is worth prioritising for new deployments in high-density areas like operating theatres and ICUs, where improved latency and spectrum management make a practical difference.
Private 5G makes sense for specific, demanding use cases
The clearest current application is hospital logistics: automated vehicles and robots that move continuously across large indoor areas need seamless connectivity without the brief interruptions that Wi-Fi handover can introduce. Dense asset tracking is another strong case, where managing hundreds of connected devices across a large campus, benefits from 5G’s handling of device density and positioning. And for future applications involving real-time remote guidance or advanced surgical assistance, the reliability characteristics of private 5G are worth planning for in new hospital builds.
Public 5G belongs in any strategy that extends beyond your walls
Pre-hospital care is the most established use case. Sending ECG data and patient vitals from an ambulance to the receiving team before arrival has clear clinical value, and several European healthcare programmes have validated this model. Remote and community care, chronic disease monitoring, post-discharge follow-up, and elderly care at home all depend on connectivity that works in patients’ homes, and newer 5G capabilities designed for low-power IoT devices are making this increasingly practical.
What this looks like in practice
Consider a large regional hospital planning a network refresh alongside a new logistics automation project. The scenario is fictional, but the decisions it involves are typical.
The vast majority of the hospital runs on Wi-Fi 7. Wards, outpatient areas, consulting rooms, imaging suites and staff areas all connect over a refreshed access point infrastructure with good coverage in the 6 GHz band. This handles EMR terminals, patient monitoring, Picture Archiving and Communication System (PACS) workflows, VoIP and everything else the clinical teams use day to day. It is reliable, well understood, and the total cost is manageable.
Alongside this, the hospital has deployed a private 5G network covering its main building and connecting corridor to the pharmacy. This supports a fleet of autonomous delivery robots that transport medication, lab samples and consumables around the clock. The robots need uninterrupted connectivity as they move between floors and through busy corridors. Wi-Fi handover introduced too much variability during testing, and the 5G network resolved it. The same private network also supports real-time tracking of high-value mobile equipment across the campus.
For anything outside the building, the hospital uses public 5G. The cardiology team receives ECG data and patient information from paramedics en route, enabling earlier triage decisions. A community nursing team uses 5G-connected tablets for remote monitoring visits, with patient data feeding directly into the hospital’s clinical systems. Neither of these use cases requires anything on the hospital’s own network infrastructure.
Three technologies, three distinct roles. None of them redundant, none of them doing the other’s job.
A few things worth getting right
The device ecosystem is the constraint that surprises most teams. The majority of clinical hardware today connects over Wi-Fi. Until 5G chipsets are standard in medical devices, any private 5G deployment will need adaptor hardware or a planned device refresh for the relevant use cases. Build this into your timeline and budget from the start.
For Wi-Fi, design quality matters as much as the generation you deploy. Clinical environments are RF-challenging: thick walls, frequent layout changes, and the interference characteristics of medical equipment all need to be accounted for. A well-designed Wi-Fi 6 network will outperform a poorly planned Wi-Fi 7 one. Proper site surveys and capacity planning are not optional.
Private 5G deployments require licensed spectrum coordination with the relevant national regulator. The framework for local private 5G licences is well established in most EU member states, though the specifics vary by country. Taking professional advice on licensing options early in the planning process avoids delays later.
Where to go from here
The wireless landscape in healthcare is not going to simplify. The number of connected devices is growing, care is increasingly moving outside hospital walls, and the applications being asked of networks are becoming more demanding. A single technology is not going to serve all of that well.
The good news is that you do not need to solve everything at once. Wi-Fi 6E or Wi-Fi 7 is a solid foundation for most hospitals today. Private 5G is worth serious evaluation if you have specific use cases that genuinely require its capabilities. And public 5G should be part of any discussion about care pathways that extend into the community.
A useful starting point: map your clinical use cases and their connectivity requirements before you make any infrastructure decisions. The technology choice tends to follow naturally from that exercise. If you would like support working through that process, our Damovo team is happy to help.
