Connecting Care in Milliseconds: Revolutionizing Wi-Fi Infrastructure and Medical Data Security Across 2,000 Access Points
Business Requirement
Hospital-wide Wi-Fi coverage to seamlessly support point-of-care mobile devices during rounds, combined with stringent access control policies.
Solution by ISS
Deployment of 2,000 Access Points utilizing a robust Layer 3 architecture, integrated with a secure Kiosk Authorization system linked to the core HIS.
System Scale & Stability
High-capacity operational threshold handling dense daily concurrent traffic without bottlenecks or downtime.
3,500 – 4,000 Devices / DayThis success story highlights a massive wireless infrastructure modernization executed by ISS Resolution for a leading hospital and faculty of medicine in Bangkok. By deploying over 2,000 enterprise-grade Access Points and introducing an intelligent Kiosk Authorization system, ISS successfully built a seamless network fabric directly integrated with the hospital’s core information management system.
From Paper Charts to Bedside Tablets: The Legacy Challenge
Historically, physicians and nursing staff navigated wards carrying thick, physical patient charts and transporting large, cumbersome X-ray films from room to room. Upon completing patient rounds, staff had to return to central nursing stations to manually transcribe handwritten notes into static desktop computers. This redundant process lengthened patient wait times and escalated the risk of transcription mistakes or data entry delays (Human Error).
The root cause was an legacy Wi-Fi infrastructure that lacked the required signal density and roaming stability to maintain persistent connections for mobile medical equipment. Consequently, the hospital required an enterprise-wide wireless overhaul capable of facilitating seamless network access for clinical staff and patients alike, governed by a rigid yet low-friction access authorization protocol.
A Mega-Project Solution: Ubiquitous, Fluid, and Secure Coverage
ISS Resolution designed and engineered a high-density, large-scale wireless architecture defined by several key infrastructure milestones:
Integration Magic: Unlocking the Power of HIS
The turning point in transforming the hospital’s clinical workflows was the seamless, native integration of the wireless network with the Hospital Information System (HIS)—the central database governing all institutional medical records.
This integration delivered immediate, tangible improvements to clinical performance. Physicians and nurses now utilize mobile tablets and laptops right at the patient’s bedside to instantaneously pull up vital signs, laboratory trends, medication logs, and high-resolution diagnostic imaging or X-rays. Eliminating the need to walk back to fixed workstations dramatically accelerates point-of-care decision-making, shortens patient queues, and optimizes treatment timelines.
Uncompromised Data Privacy: An Ironclad Defense for Medical Records
Recognizing that medical data is highly sensitive and subject to strict data protection regulations, ISS Resolution integrated stringent security and data privacy measures directly into the system architecture:
- The Kiosk Authorization interface engineered by ISS communicates with the central hospital system exclusively to “verify the active Hospital Number (HN) of the visiting patient.”
- No Protected Health Information (PHI) or personally identifiable information (PII) is cached, written, or retained on the Wi-Fi authentication servers.
- All network authentication servers reside inside the hospital’s physical Data Center, insulated from external vectors by high-performance enterprise firewalls.
The success of this deployment goes far beyond a standard Wi-Fi installation. ISS Resolution has successfully established a “digital backbone” that drives operational agility, protects critical data assets, and empowers medical professionals to deliver fast, life-saving care without infrastructure barriers.
