Comparing the Performance of Devices using Bluetooth Low Energy v4 and v5

Bluetooth Low Energy (BLE) is among the most ubiquitous low-power wireless technologies in the rapidly growing Internet of Things (IoT). Due to the increasing number of devices and the vast number of potential IoT applications (e.g., in smart cities, smart buildings, and connected health), wireless communication requirements are constantly changing and standards are being adapted accordingly.

Devices compliant to the latest BLE specification (BLE v5.x) can enjoy longer transmission ranges and higher throughput compared to those using BLE v4.x.Furthermore, a direction finding (Angle-of-Arrival (AoA)/Angle-of-Departure (AoD)) feature was added in BLE v5.x,and many others. Since retrofitting devices can be both complex and costly, the industry is interested in evaluating how beneficial would it be to upgrade their products to the latest BLE specification. .
