Bluetooth Low Energy (BLE) 5.0 represents a fundamental quality leap for the IoT and wearable world. Compared to previous versions, it offers significant improvements in speed, range and energy consumption.
Data transfer speed has doubled compared to BLE 4.2, reaching 2 Mbps. This enables faster communication between device and smartphone, essential for real-time applications like security alarms.
Range has quadrupled: up to 400 meters in open field (theoretical), with 100 meters as reliable practical range. For smart bags, this means the user receives the alarm even when the bag is at considerable distance.
Energy consumption remains extremely low, enabling weeks or months of battery life with miniaturized batteries. BLE 5.0 also supports extended advertising mode, which allows transmitting more data without establishing a formal connection.
On the security front, BLE 5.0 implements AES-128 encryption for all communications, protecting data transmitted between the bag and smartphone from interception and man-in-the-middle attacks.
Smart bag companies are adopting BLE 5.0 as the primary communication technology precisely because of these advantages. The combination of range, low consumption and security makes it ideal for a personal protection device that must function reliably and continuously.
