A hospital runs several networks that happen to share a building. Clinical systems carry patient data and cannot tolerate interference. Staff move constantly and expect their devices to follow. Patients and visitors want guest access that never comes near clinical infrastructure. Immunity delivers all three on one certified estate.
Healthcare combines the three things that individually make wireless difficult: an unforgiving uptime requirement, hostile RF conditions, and traffic that must be provably separated.
A hospital does not close. Changes have to be made alongside live clinical operations, which rules out the "take it down over the weekend" approach most other sectors rely on.
Dense construction, lead-lined imaging rooms, metal-framed beds and equipment trolleys, and long corridors all attenuate and reflect signal. Coverage that models cleanly on a floor plan frequently fails in the ward.
Clinicians walk between wards, theatres, diagnostics and offices while holding an active session on a handheld or trolley-mounted device. A roaming failure is a clinical workflow interruption, not an inconvenience.
Patients and visitors expect Wi-Fi. That access must be demonstrably incapable of reaching clinical systems — a requirement that is as much about being able to evidence separation as about achieving it.
We survey and design per area, because a ward, a theatre and an outpatient waiting room have very different requirements.
| Area | What it needs | How we cover it |
|---|---|---|
| Wards and bed bays | Consistent coverage at bedside through dense partitions | Indoor access points placed from survey, not corridor-only |
| Theatres and procedure rooms | Reliability and predictable behaviour near shielded areas | Dedicated coverage designed around shielding and equipment |
| Corridors and lifts | Continuous roaming as staff move | Overlapping cells tuned for handover, not maximum power |
| Diagnostics and imaging | RF-hostile rooms adjacent to busy areas | Careful placement to avoid dead zones at room thresholds |
| Outpatient and waiting areas | High visitor device density | Density-oriented coverage with guest portal onboarding |
| Grounds, ambulance bays | Outdoor connectivity | Ruggedised outdoor access points (AX821) |
The whole design proceeds from one principle: clinical, staff and guest traffic share the physical infrastructure and nothing else.
Patient systems and connected medical devices on their own VLAN, with policy that reflects how sensitive and how intolerant of interruption they are.
Clinician and administrative devices, roaming freely across the building but with no path into the guest network.
Internet access only, through a captive portal with time-bound sessions and bandwidth control, with client isolation so devices cannot see each other.
CCTV, access control and building services segmented separately — these are often the least-patched devices in the estate.
Separation is enforced on distinct VLANs by NetForce switching, with inter-VLAN policy applied at the NetGuard X5 gateway — so the isolation is structural rather than a rule that can be misconfigured away.
A hospital deployment uses the full stack, chosen for predictability rather than peak specification:
All of it is designed and manufactured by Immunity in India, at our facility in Sanand GIDC, Gujarat. Our equipment is MTCTE certified (and CE, FCC & RoHS compliant), with products listed on the Trusted Telecom Portal. Ask us for current certification status on the models in your design and we will confirm in writing.
Most hospitals carry this entire estate with a handful of IT staff. The operating model matters as much as the hardware.
Central monitoring surfaces a failing access point or a saturated area before clinical staff report a problem, which is the difference between a maintenance task and an incident.
Configuration changes, firmware and troubleshooting are done centrally rather than by walking to a comms cupboard on another floor.
New areas are provisioned from a template, so a ward refurbishment does not become a bespoke networking project.
Access points, switching, gateway and cloud come from one Indian OEM, so an escalation does not become a negotiation between suppliers.
Yes. Guest access runs on a separate VLAN enforced in switching hardware with policy at the gateway, so there is no path from a visitor device to clinical systems.
Phased installation area by area, alongside the existing network, with validation after each phase. No dependency on a maintenance window.
Seamless roaming across NetWave access points under unified control is a core design objective, since dropped sessions interrupt clinical workflows.
These are surveyed specifically. Shielding creates predictable dead zones at thresholds, which we design around rather than discover after installation.
Our equipment is MTCTE certified (and CE, FCC & RoHS compliant), with products listed on the Trusted Telecom Portal. Ask us for current certification status on specific models.
Healthcare buying committees ask questions that other sectors do not, and it is worth addressing them directly.
It is usually not enough to say clinical and guest traffic are separated; you need to be able to show how. Because separation is enforced on distinct VLANs in switching hardware with policy at the gateway, the design is documentable and auditable rather than resting on configuration alone.
Our equipment is MTCTE certified (and CE, FCC & RoHS compliant), with products listed on the Trusted Telecom Portal, and it is manufactured in India. For institutions with domestic procurement preferences, that matters. Ask us for current certification status on specific models and we will confirm in writing.
Clinical environments need a support model, not just a warranty. Support comes directly from the OEM with India-based engineers, so an escalation does not travel through an overseas vendor queue.
Hospital networks are frequently funded and built in phases, block by block. The estate can be extended over time under one management console, so a phase-two building joins the existing network rather than becoming a second one.
A useful design needs a little information up front. None of it is onerous, and it saves a round of revisions later.
From that we produce a design document with access point count and placement, switching and PoE requirements, segmentation design and the management model. You are free to tender against it.
Tell us about your buildings, clinical systems and where coverage fails today. Our engineers will propose a design and send datasheets, usually within one business day.
