BLE stands for Bluetooth Low Energy, which is a one-way wireless network communication technology limited to personal area. It is very similar to Wi-Fi and Zigbee but the only difference is BLE is for short-range and cost is very low. BLE is different from Bluetooth that it does not exchange of high-speed data and require lesser battery at a cheaper cost.
All the operating systems such as IOS, Android, Windows phone, Blackberry, Mac Os, Linux, Windows 8 and Windows 10 support BLE.
BLE uses 2.4 GHz radio frequency and uses 2MHz channels, it allows dual-mode devices to share a single radio antenna but uses a simple modulation system. The data bit rate is 1Mbit/s and the maximum transmit power is 10 mW.
Main features of BLE are
- Low power consumption
- Maximum peak power is less than 15mA and the average is 1µA.
- The device remain in sleep for maximum time and wakes up on when required.
- Cost-efficient and compatible
- Robustness, security and reliability
- Wireless coexistence
- 300m connection range up to 10dBm radio chipset
- Ease of use and integration.
