Problem
Call systems in hospitals are either wired and expensive, or they do not exist. Without one, when a patient calls nobody hears it, the response is late and nothing is recorded.
Solution
Wireless LoRa buttons + on-screen alarm + web-based management. Every call is recorded together with the person, location, time and response time.
Result
The system was commissioned in several clinics. Since call durations became measurable, it can be used directly in quality studies.
