In the wards of Ningbo Traditional Chinese Medicine Hospital, every press of the call button is critical to patients’ health and safety. As the hospital’s Phase I renovation project progresses, the traditional ward call system has been facing challenges such as insufficient stability, response delays, and complex operations and maintenance. With its industrial-grade PoE all‑scenario networking solution, Guangwangshi has built a “zero‑interruption, intelligent management” smart ward call system for this Grade III hospital.
Challenges in Medical Settings
Ningbo Traditional Chinese Medicine Hospital, a key TCM hospital in Zhejiang Province, sees over 3,000 outpatients daily, placing extremely high demands on its ward call system:
24/7 uninterrupted operation: ICU and emergency ward call systems must be absolutely reliable
Millisecond‑level response requirements: The delay between a patient’s call and the nurse station’s response must be less than one second
Complex electromagnetic environment: With dense medical equipment, the network must exhibit exceptional anti‑interference capabilities
High‑density access requirements: A single ward floor must support more than 200 call terminals online simultaneously
Guangwangshi Solution:
The project employs Guangwangshi’s industrial‑grade PoE switch architecture, enabling a “zero‑perception upgrade” for the hospital’s security system.
10‑Gbps Access, Edge as Core
A Guangwangshi 10‑Gbps core three‑layer industrial PoE managed switch is deployed to build the digital foundation of the ward call system:
48 Gigabit PoE ports plus 4 10‑Gbps optical ports, with up to 30W per port
Compliant with IEEE 802.3af/at standards, automatically identifying powered devices and ensuring safe power delivery
Operates across a wide temperature range of -40°C to 75°C, with IP40 protection and a fanless silent design
Dual redundant power supplies provide failover protection, ensuring the system never goes offline
Network Architecture: Triple Reliability Assurance
ERPS ring network technology (<20ms self‑healing): In case of link failure, communication can automatically recover within 20 milliseconds
MSTP multi‑instance protection (<50ms switchover): Provides dual redundancy at both device and link levels
Intelligent power management: PoE ports support priority settings, prioritizing power supply to critical ward call terminals
Smart Cloud‑Based Management
Implemented via both the ONV‑NMS management platform and a mobile app:
A unified Guangwangshi network management software platform is deployed, enabling visualized status monitoring of all network devices.
▷ Platform side: Visualized topology management of all network devices, with automatic anomaly detection and alerts
▷ Mobile side: Real-time push notifications of device alerts, triggering immediate operational responses with zero latency
Key Value:
Real-time monitoring of PoE power status: Voltage, current, and power consumption for each port are clearly displayed
Failure prediction and localization: Automatically detects device anomalies and precisely identifies fault locations
Remote maintenance and configuration: Supports multiple management interfaces including Web and CLI, reducing on-site operations
Implementation Highlights:
Single‑cable power and data transmission
Using a single network cable to simultaneously transmit data and supply power to devices, eliminating the cumbersome power cabling required by traditional systems, saving 5.6 kilometers of cable installation and cutting construction costs by 40%
Ultra‑reliable design
Industrial‑grade aluminum housing with 6kV lightning protection ensures stable operation even in complex electromagnetic environments typical of medical settings, achieving system availability of 99.999%
Intelligent energy management
Smart scheduling of PoE power, supporting automatic energy saving during idle periods, reducing overall power consumption by 35% and annual electricity costs by 26%
Implementation Highlights:
Results of Digital Transformation:
Call response speed improved threefold, reducing patient wait times from an average of 2.3 minutes to just 45 seconds
System operation and maintenance costs slashed by 60%, with remote management cutting on-site maintenance work by 80%
Equipment lifespan extended twofold; industrial‑grade design ensures five years of trouble‑free operation
Nurse productivity increased by 40%, while zero‑latency data transmission enables caregivers to respond faster to patient needs
User Feedback:
“The most significant breakthrough of this smart upgrade lies in achieving millisecond‑level self‑healing reliability at the medical‑grade network level. The system maintains stable operation even under extreme weather conditions or power fluctuations, significantly improving healthcare staff response efficiency. Guangwangshi’s industrial‑grade solution demonstrates professionalism and stability that fully meet the stringent requirements of a Grade III hospital for critical systems,” said the head of Ningbo Traditional Chinese Medicine Hospital’s smart transformation project.
