Bluetooth Low Energy
Bluetooth Low Energy (BLE) is a wireless personal area network technology independent of the classic Bluetooth and has distinct compatibility.

BLE features a significant reduction in power consumption and also cost as compared to standard Bluetooth. Very low-power devices which operate for months or years on a button cell uses BLE for communication. However, a similar communication range is maintained and the same 2.4GHz frequency band is used.
As mentioned earlier, BLE’s compatibility is different from the basic Bluetooth protocol but BR/EDR and LE systems are permitted.
Bluetooth 5.0 is the latest Bluetooth standard in the industry. Bluetooth 5.0 supported devices can transfer data at up to 2Mbps speed which is twice the speed of Bluetooth 4.2. In addition, the range is extended up to 260 feet (if no walls interfere). BLE 5.0 will have a big impact on smart home systems and other IoT devices as per the experts. Low energy, increased range, and increased speed means that the devices can switch over from Wi-Fi.
