Bluetooth is especially sought after in medical applications. Such applications typically involve one or more sensors to monitor a patient’s blood pressure, glucose level, EKG or other sensory data. The collected data can be analyzed locally or perhaps forwarded via the Internet where a doctor can monitor the data values.
Benefits of using Bluetooth
BLE is expected to play a huge role in facilitating the Internet of Things (IoT). IoT is a technology where anything can be connected with one another and to the Internet, forming large networks. As the technology expands, it will enable the monitoring and controlling of connected devices from anywhere, by people or by other devices. In a smart home, for instance, one might set some relaxing lighting, convenient temperature, and even put on the right mood of music at home that awaits just the right time before arriving from work.
When it comes to IoT, BLE has several advantages over other wireless protocols. BLE is more energy efficient than Wi-Fi or even ZigBee, which benefits battery powered devices. In comparison with other low power technologies like ZigBee, LoRa or Z-Wave, BLE is also the most widespread one of them as it is present in all modern smartphones. Moreover, as the density of connected devices increases, signal disturbance and interference need to be considered. BLE is the most successful in resisting interference, thus providing the more robust connection in such conditions.
As Bluetooth technology evolves and improves, it gets more and more difficult to decide in advance when or where it absolutely should be avoided. A better approach is to take a case-by-case consideration and test the technology against the specific requirements if possible. BLE has proven itself in applications with requirements for safety, security, range, robustness even in harsh industrial environments, and more.
