What is BLE?
BLE is WPAN designed and marketed by the Bluetooth Special Interest Group aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
It was introduced by the Bluetooth Special Interest Group (Bluetooth SIG) in December 2009 as part of the Bluetooth 4.0 specification.
The primary advantage of BLE compared to 'Classic Bluetooth' is lower power consumption, which translates to longer battery life. For example, BLE can run for multiple years on a single coin-cell battery, such as a CR2032 battery used in wristwatches.
Bluetooth LE can also communicate over a longer range than the 100-meter distance Classic Bluetooth supports. It also supports fast connection setup with a latency of 3 ms compared to the 100 ms latency of Classic Bluetooth. ONE
Bluetooth Low Energy (BLE) in Medical Devices
Bluetooth Low Energy (BLE) has become a pivotal technology in the field of healthcare, particularly in medical devices, due to its low power consumption and secure, robust connectivity.
Advantages of BLE in Medical Devices
BLE's power efficiency makes it ideal for devices that require long battery life. It provides secure, encrypted connections, crucial for protecting sensitive health data. BLE also supports multiple connections, enabling one device to communicate with several others simultaneously.
Applications of BLE in Medical Devices
BLE is used in wearable devices like heart rate monitors, fitness trackers, and smartwatches. These devices gather data for personal health monitoring and fitness tracking.
Remote Patient Monitoring
In remote patient monitoring systems, BLE enables the transfer of patient data from medical devices at home to healthcare providers, aiding telemedicine efforts.
BLE technology is used in hospital equipment for asset tracking and real-time data monitoring, improving efficiency and patient care quality.
