When most people hear the word wireless, they immediately think of WiFi. It’s what connects our phones, laptops and smart TVs. But in hospitals, when it comes to something as critical as a nurse call system, WiFi might not be the best option.
That’s where Radio Frequency (RF) technology comes in. While both WiFi and RF operate wirelessly, their use cases and reliability differ significantly—especially in clinical settings.

What’s the difference?
WiFi is designed to handle heavy data like video calls, browsing and media streaming. It works on high frequencies like 2.4 GHz and 5 GHz, which can often get congested and interfere with other systems. RF technology used in nurse call systems, typically around 433 MHz, is designed for short, quick, reliable signal transmission—exactly what’s needed in an emergency.
Why RF is better for nurse call systems
Independence from IT networks: RF systems don’t rely on internet or LAN connections, so they continue working even if the hospital network is down.
No interference: The 433 MHz frequency avoids overlapping with medical equipment and IT systems, making it safe and stable.
Reliable coverage: RF signals penetrate walls and medical infrastructure better than WiFi, ensuring consistent performance.
Lower power consumption: Devices using RF consume less power, making battery-operated systems more durable.
Simpler and cost-effective: RF systems are easy to install without the complexity of routers or cybersecurity concerns.
Conclusion:
For hospitals, wireless doesn’t always mean WiFi. When patient safety depends on quick response times, RF-based wireless nurse call systems offer a dependable, low-maintenance solution that just works.
