Challenge
The nursing device needed reliable links to patient-side equipment, clearer remote consultations, and better power management, while preserving clinical function and avoiding unnecessary recertification.
Solution
We redesigned the firmware around BLE, Bluetooth Classic, and GSM/MBIM links, added digital signal processing for noise and echo cancellation, and revised power management.
Results
- Extended battery life to approximately two days
- Improved remote consultation voice quality
- Added multi-patient monitoring capability
- Lowered support burden and recertification risk
