Despite the fact that until now these two technologies have been used for very different purposes, for some time Wi-Fi signals have been used to gain insights about physical locations, such as retail stores. From this perspective, we are going to compare below the main differences between Bluetooth Low Energy and Wi-Fi.
How Wi-Fi tracking works
Most people have in their pockets a mobile phone with the Wi-Fi turned on, which means it is constantly looking for Wi-Fi networks. This active seeking of Wi-Fi networks is used by retailers to detect the presence of customers in the store, or in the surrounding area. Users do not have to manually connect to any network, in fact the whole the process is done without any user intervention.
How Bluetooth Low Energy works.
The seeking of signals is done in the opposite way: Bluetooth Low Energy devices (e.g. mobile phones) are constantly looking for signals of Bluetooth Beacons. When these signals are detected, some actions are triggered in the device – actions such as showing context-aware content (messages, images, etc.) –
