Nawaloka Hospitals: Mission-Critical Medical IoT & Patient Wi-Fi Slicing
Deploying UniBox controllers, UniMax high-density access points, and 3-tier logical VLAN slicing to segregate ICU telemetry, electronic medical records (EMR), and guest internet.
About Nawaloka Hospitals PLC
Nawaloka Hospitals PLC is Sri Lanka's premier private multi-specialty healthcare provider, established in 1985 as the country's first fully fledged private hospital. Operating major tertiary care hospitals in Colombo and Negombo, Nawaloka provides advanced clinical care across 400+ inpatient beds.
With modern digital medical equipment, wireless vital monitoring in ICUs, and tablet-based doctor rounding, reliable wireless networking is essential to patient clinical outcomes.
Nawaloka selected Indio Networks to engineer a robust, segregated wireless network that isolates clinical telemetry and EMR hospital management systems from guest visitor traffic while ensuring strict patient data privacy and sub-millisecond roaming.
Project Profile
Overview, Requirements & Solution
A consolidated executive summary of Nawaloka Hospitals' clinical Wi-Fi deployment with Indio Networks.
Overview
Nawaloka Hospitals required an enterprise wireless infrastructure to simultaneously support high-bandwidth guest Wi-Fi, critical medical device telemetry, and tablet EMR access without compromising security.
Key Requirements
- 3-Tier Network Slicing: Isolate Doctor/Staff, Medical IoT Equipment, and Inpatient/Visitor Guests.
- Zero Packet Loss Roaming: Continuous connectivity for mobile nursing workstations and ICU monitors.
- Hospital Management Sync: Authenticate patients against registration desk records.
- RF Interference Immunity: Certified safe operation alongside sensitive imaging and dialysis machines.
How We Helped
- Deployed UniBox enterprise controllers with AAA & firewall.
- Installed UniMax dual-band access points & PoE switches.
- Configured isolated VLAN slices with QoS prioritization.
- Implemented SMS/OTP verified patient captive portal.
Operational Challenges & Technical Solutions
Solving healthcare cybersecurity constraints, RF shielding barriers, and multi-tenant traffic contention with Indio Networks.
The Operational Challenges
Key constraints, bottlenecks & network hurdlesCross-Network Cyber Contamination
Patients and visitors sharing the same subnet as hospital servers created extreme risk of malware and unauthorized medical record access.
Heavy Concrete & Lead-Lined Radiation Walls
Dense hospital architecture and X-ray shielding caused severe dead zones and roaming drops for doctors on tablet rounds.
Bandwidth Starvation for Medical IoT
Visitors streaming video content choked network pipes required for real-time telemetry and wireless PACS imaging transfer.
Lack of Inpatient Access Control
Hospital lacked automated guest billing or duration-limited passes for day-care vs multi-day admitted inpatients.
The Indio Solution
Tailored architecture, controller features & management3-Tier Logical VLAN Slicing
Completely isolated guest traffic from internal hospital databases and IoT medical monitors using UniBox stateful firewall rules.
High-Density UniMax AP Deployment
Optimized AP placement with 802.11k/v/r fast roaming protocols to provide seamless handovers as physicians walk between patient wards.
Mission-Critical QoS Prioritization
Guaranteed dedicated minimum bandwidth for medical IoT telemetry and hospital management software over public visitor browsing.
Automated Inpatient Captive Portal
Branded captive portal offering free high-speed access for admitted patients via room/mobile verification and speed tiers for visitors.
Implementation Journey
Indio Networks executed an uninterrupted hospital network installation with zero clinical downtime, preserving ongoing emergency ward and surgical operations.
Seamless & Turnkey
Engineered for high availability, complete patient data isolation, and centralized cloud monitoring.
Phase 1: RF Mapping & Medical Zone Assessment
Conducted detailed RF heat mapping across surgical suites, ICUs, and inpatient wings to eliminate signal dead spots.
Phase 2: UniBox Gateway & 3-Tier VLAN Segmentation
Configured UniBox core gateway with strict firewall rules segregating medical equipment, doctor tablets, and guest networks.
Phase 3: High-Density UniMax AP Commissioning
Installed enterprise UniMax APs powered by US-24MP PoE switches, configuring 802.11r seamless fast roaming.
Phase 4: HMS Integration & Patient Portal Activation
Launched SMS/OTP verified patient portal with fair-usage controls and integrated with Indio Cloud for 24/7 telemetry monitoring.
Project Results & Business Value
The implementation of Indio Networks' solution delivered tangible performance gains, reduced operational overhead, and elevated user satisfaction.
VLAN Isolation
Complete physical & logical segregation between medical IoT and guest Wi-Fi.
Data Compliance
Zero patient health record leakage with enterprise AAA encryption.
Roaming Latency
Unbroken sessions as physicians carry EMR tablets between patient beds.
Patient Satisfaction
High-speed inpatient Wi-Fi driving superior patient recovery ratings.
"In a critical hospital environment, network failure or data cross-contamination is unacceptable. Indio Networks provided a secure, segregated architecture that guarantees medical IoT uptime while keeping patient records strictly protected."
