Evaluation of Bluetooth Low Energy Performance for Local Positioning Systems in Wireless Communications

Abstract

In the coming years, billions of devices are anticipated to be equipped with Bluetooth Low Energy (BLE), a developing low-power wireless technology designed for short-range control and monitoring applications. Wearables, domestics, e-health systems, and other applications of small, tiny, and embedded sensors are only a few examples of the many uses of this ubiquitous technology in daily life. Wireless communication is important in this situation, and BLE is becoming more and more well-liked among the options. Broad diffusion, low energy consumption, and high performance are combined in BLE. This paper begins with a detailed explanation of the protocol, emphasizing its key features and implementation specifics. The state of the art regarding BLE performance and characteristics is reviewed in the second section. To determine the present boundaries of BLE technology, we specifically examine throughput, the maximum number of connectable sensors, battery consumption, latency, and the maximum attainable range. We assess how the quantity of ads affects the throughput and effective data reception rate. We demonstrate that BLE can still assure adequate data reception rates and meet the needs of a wide range of IoT applications despite the advertisement collision rate in our experiment fluctuating between 0.22 and 0.33 due to the multiple transmissions of adverts.
