We all have used Bluetooth for many times or may be using currently also to transfer the data from one device to the other. Bluetooth was invented by the telecom company Ericsson in 1994 for the transmission of data over short distances wirelessly.
Bluetooth Low Energy (BLE) 4.0 is not so new technology but implementing in today’s generation device at very large scale because of their advantages over classic Bluetooth.
Bluetooth Low Energy which formerly marked as Bluetooth Smart is a wireless personal area network technology whose standards are designed and marked by Special Internet Groups (SIG), which is a non-profit organisation which takes care of development and licensing of Bluetooth technologies to the manufacturers.
BLE is different in comparison with the classic Bluetooth in following ways:
- BLE uses very low every as you could understand by its name for the same range of communication as classic Bluetooth
- BLE however uses the same 2.4 GHz radio frequencies as the classic one, but uses different modulation techniques
- It is used in very small size devices with small circuitry which also makes it cheap
- Can operate for few or even years on a single button cell due to low energy consumption
- Distance or range can be more than 100m (330 ft.)
