Why is BLE beacon technology used instead of Wi-Fi infrastructure which is already installed? [closed]

The Beacon radiates signal. A nearby Bluetooth enabled device receives this signal. When a particular application recognizes its signal, it connects it to an action or content track stored in the cloud and allows the user to view it. By editing the application on your phone, you can set how it reacts to signals.

For example:

Beacon systems are installed in the shops within a mall. All Beacons have their own fixed ones. When the signal of Beacon, which broadcasts with its own private ID, reaches your phone, the application of the shopping center (which should be pre-installed) will process this signal and give you outputs such as the store discount coupon, navigation proposal varying according to the application's program.

When I set out from this example, I have the following question in my mind. Why is BLE beacon technology used instead of Wi-Fi infrastructure (already installed in phone and mall)? When we periodically scan Wi-Fi signals, we can access SSID, MAC and RSSI information. When we use this information as a query tool by using an application, the approximation recognition with the beacon is completed. In this way, we do not have to invest in BLE beacon infrastructure. What is the keypoint of BLE beacon technology? Why do people need to use this technology?
