Features of Building MESH Networks Based on Bluetooth Low Energy 5.1 Technology

Currently, wireless technologies are being actively developed, as well as new methods of wireless transmission. The paper considers the Bluetooth wireless communication standard, namely, its specification 5.1. The purpose of the work is to consider the features of using BLE MESH networks in a multi-storey reinforced concrete building. A comparative analysis of the protocols that can be used to create mesh networks was made, highlighting their features, advantages and disadvantages. A MESH network was built on the basis of the Bluetooth standard, and this network was tested in a multi-storey building made of reinforced concrete. The possibilities of building a BLE MESH network using various modern microcontrollers are considered, and a choice is made in favor of a processor-based controller from Microchip.
