Normal RF vs Wi-Fi vs LoRa: Which Wireless Technology Is Best for a Nurse Call System?

Choosing the Right Wireless Nurse Call System

Choosing the right wireless nurse call system is a critical decision for hospitals. While many products claim to be wireless, the underlying technology—Normal RF, Wi-Fi, or LoRa—determines reliability, scalability, and long-term performance.

Why Wireless Technology Matters in Nurse Call Systems

A nurse call system is a mission-critical hospital communication system. The wireless technology used must ensure:

1. Reliable call delivery
2. Multi-floor and hospital-wide coverage
3. Low power consumption for battery-operated devices
4. Easy scalability as the hospital grows

Normal RF-Based Nurse Call Systems ( 433Mhz)

Normal RF systems use basic proprietary radio communication.

Advantages

1. Low initial cost
2. Simple setup for small clinics

Limitations

1. Short indoor range
2. Poor wall and floor penetration
3. Requires repeaters
4. Limited scalability

Wi-Fi Based Nurse Call Systems

Wi-Fi-based systems operate on the hospital’s existing Wi-Fi network.

Advantages

1. Easy integration with dashboards and apps

Limitations

1. High power consumption
2. Dependence on hospital IT infrastructure
3. Risk of network congestion affecting alerts

LoRa-Based Nurse Call Systems

LoRa technology is designed for low-power, long-range, and reliable communication.

Advantages

1. Hospital-wide and multi-floor coverage
2. Excellent wall and floor penetration
3. Battery life lasting several years
4. Minimal infrastructure required
5. High reliability and scalability

Final Recommendation

For hospitals seeking reliable communication, easy expansion, and low maintenance, LoRa is the best wireless technology for nurse call systems.
