Quick answer
Build a network plan from devices and required communication flows. Separate guest, clinical, connected-device and management traffic as appropriate to the risk assessment, then test both allowed and prohibited paths. Verify usable connectivity where care occurs; an office speed test does not establish bedside application readiness.
Draw the required communications before changing the network
A nursing facility adds cloud EHR access, a telehealth cart and connected measurement devices while residents and visitors use guest Wi-Fi. Treating every device as a general internet client can obscure critical dependencies and unnecessary access paths.
The voluntary HHS Healthcare Cybersecurity Performance Goals include separating mission-critical assets into discrete network segments to limit lateral movement. They also address configuration and telemetry. These are useful planning goals, not a claim that one network diagram automatically satisfies HIPAA.
Inventory actual devices, locations, responsible organizations, support status and required destinations. Include printers, management consoles, remote support, DNS and time services. A network change that blocks an undocumented dependency can disrupt care even when the intended security boundary is sound.
Build an allowed-flow table
This original example is a starting structure for an engineer-reviewed design.
| Source group | Necessary destination | Business reason | Explicit test |
|---|---|---|---|
| Clinical workstations | Approved EHR service and required infrastructure | Chart access | Complete a synthetic clinical workflow |
| Connected devices | Approved gateway or service | Device data exchange | Send a test observation through the documented path |
| Guest devices | Approved internet access | Resident/visitor connectivity | Confirm no route to protected internal services |
| Management stations | Specified device administration endpoints | Authorized maintenance | Confirm ordinary clinical and guest devices cannot use the same path |
| Telehealth equipment | Approved video and coordination services | Scheduled consultation | Rehearse the actual call and fallback |
Record direction, protocol, destination, authentication and change owner with the technical team. Avoid an unrestricted “any-to-any” exception merely to make an initial demonstration work. If a supplier cannot describe its requirements, keep the uncertainty visible and resolve it through a controlled test.
Walk the workflow through the building
Test the proposed device in resident rooms, hallways, treatment areas and other actual work locations. Include doors closed where relevant, peak expected use and movement between access points. Use synthetic records and record timestamps, application response, disconnects and recovery behavior. A network engineer can correlate these observations with coverage and performance measurements.
In a fictional walk test, nine of ten locations complete chart loading reliably; one wing repeatedly drops sessions during roaming. The average result is not a pass for that wing. Record the affected workflow and remediate the access-point, client or configuration issue before relying on it for routine care.
The required performance threshold should come from the application and actual task, with local clinical input. This guide does not prescribe a universal bandwidth number or signal threshold for all nursing facilities.
Test isolation and service failure safely
Authorize security staff to verify that a guest device cannot reach protected internal services and that connected-device segments cannot initiate unnecessary communications. Test the intended boundary after firewall or wireless changes. A separate network name is a label; effective routing and policy establish the boundary.
Also rehearse loss of the primary internet path, DNS failure or a supplier endpoint outage through an approved non-disruptive method. Establish which workflows remain available and how staff recognize the failure. The broader downtime plan supplies care continuity; this exercise identifies the infrastructure conditions that trigger it.
Assign infrastructure responsibilities in the purchase
For every open requirement, name whether the facility, managed network provider, device manufacturer or application supplier will implement and verify it. Budget cabling, access points, switches, connectivity, monitoring and ongoing configuration work where needed. Do not bury these dependencies in an EHR implementation schedule without a funded owner.
Acceptance should include the inventory, reviewed flow table, observed bedside results, isolation tests and unresolved exceptions. Retest affected paths when a new device or service is introduced. That keeps network readiness connected to actual resident-care work rather than to an internet speed screenshot.
Questions & answers
Does creating separate Wi-Fi names establish isolation?
No. Separate names can still lead to the same underlying network. Verify routing and access controls with authorized tests.
Can bandwidth alone predict EHR performance?
No. Coverage, interference, latency, packet loss, device roaming and application dependencies can affect the observed workflow.
