The Internet of Things helps to have every individual interconnected with their surroundings and to interact with them through smart devices. In recent years, Bluetooth Low Energy (BLE) technology has become very popular in smart infrastructures, the medical field, the retail industry, and many more areas due to its availability in a plethora of wireless devices. BLE is widely used in IoT devices, such as smartphones, smart watches, and BLE beacons. Beacons are small, low-cost, and low-power wireless transmitters that bring attention to their location by broadcasting a signal with a unique identifier at regular intervals. BLE beacons are a promising solution for many smart city applications, from proximity marketing to indoor navigation. However, they do pose security and privacy challenges. This work discusses the characteristics of BLE beacons, the applications that can benefit from them, and the challenges they pose while trying to identify research opportunities and future directions.
翻译：近年来,蓝牙低能技术在智能基础设施、医疗领域、零售业以及许多其他领域变得非常流行,因为无线装置中有大量的无线装置,这些无线装置,如智能手机、智能手表和无线信标等,都广泛使用无线装置。 Beacons是小型、低成本和低功率的无线发射机,通过定期广播带有独特识别标志的信号,吸引人们注意它们的位置。 Blue牙低能灯是许多智能城市应用(从近距离营销到室内导航)的一个大有希望的解决办法。然而,它们确实构成安全和隐私挑战。这项工作讨论了无线信标的特点、能够从这些信标中受益的应用以及它们在努力确定研究机会和今后方向时所带来的挑战。
