Determination of Maximum Allowable Data Transfer Rate by Bluetooth LET Energy Method in WSN
Siddharth Sriram · 2023
Bluetooth Low Energy (BLE) is an advanced technology designed by the Bluetooth Special Interest Group (SIG) to enable and provide very low power wireless communication between devices. BLE is the dominant protocol used in wireless sensor networks (WSNs). Using BLE technology in a WSN allows users to collect data, control and manage networks of devices, provide real-time monitoring and control, and improve the accuracy of sensor networks. The maximum allowable data transfer rate for BLE in WSNs is 8.4 Mbps. This transfer rate is achieved when all of the network nodes are simultaneously transmitting data. Additionally, this rate can be adapted depending on the specific application requirements. For instance, the rate can be adapted to support slower network throughputs, such as to allow for higher latency and lower complexity applications, or to enable faster data transfer rates for real-time applications that require more data. In addition to the maximum data rate, the increased networking capabilities offered by BLE also enable longer range communication. With BLE, WSNs can cover a much greater distance than traditional wireless technologies, ranging up to 400 meters in a line-of-sight environment. Moreover, even when the signal strength is weak and the line-of-sight environment is not favorable, BLE can still be used to typically cover 30 meters, which is much more than the 10-meter range of traditional wireless communication. Overall, BLE technology is an attractive option for users looking to build a robust, low power, and reliable WSN that offers high data rates and long-distance communication.
