Advantages and Typical Applications of Bluetooth Low Energy

As a popular communication technology for IoT applications, currently, Bluetooth Low Energy's biggest competitors in wireless communication protocols are Wi-Fi, ZigBee and other protocols. These types of communication technologies require access to the network, and Wi-Fi is undoubtedly the best choice for accessing the network from physical network devices, but compared to Bluetooth low energy technology, Wi-Fi is more of a physical network when building a wireless network. Saying WiFi is only for certain situations. The low-power Bluetooth communication standard is more beneficial than other communication methods.

In a smart home, many devices are equipped with Bluetooth modules, such as smart locks, fans and curtains. Large devices are matter networks, facilitated by wireless modules and internet connections (matter and matter). Data transmission between people and things requires wireless modules. BLE module is one of the most common wireless modules. Bluetooth Low Energy, also known as "Bluetooth Smart", is a wireless communication technology that has been revised and marketed by SIG.

Analysis of Bluetooth Low Energy Advantages

1. The low-power communication distance of Bluetooth is about 100 meters (the maximum distance of Bluetooth 5 is 300 meters). Because this distance is not clearly defined, Bluetooth application solution manufacturers can determine Bluetooth with a communication distance of less than 100 meters.

2. Bluetooth low energy technology is widely used in mobile terminals. Bluetooth Low Energy is supported by mainstream mobile phone operating systems such as Android and iOS. This huge ecosystem created Bluetooth Low Energy technology.

3. The low power consumption of Bluetooth is powered by a small button battery, which can well solve the power supply problem of current low-power Bluetooth devices in the Internet of Things. Standard coin cell batteries can last for years.

The reason the low power consumption of the bluetooth module is very energy efficient is that it has an ultra-low peak standard that consumes almost no power in idle mode.

4. The data transmission speed is up to 2Mbps (Bluetooth 5 is 2Mbps).

Application of Bluetooth Low Energy Technology

Bluetooth low energy technology has been popularized in various industries such as smart fashion, sports healthcare, smart home, etc., and almost completely uses low-power communication protocols. Many Bluetooth solution manufacturers also work in industries related to solution development.

1. Sports field: smart wearable instruments, sports equipment, heart rate monitoring instruments, etc.

2. Medical field: low frequency massager, body temperature correction, blood pressure correction, electronic scale, etc.

3. Smart home field: smart locks, curtains, home appliances, etc.

4. Industrial field: material tracking, asset management, etc.

5. Other fields: beacons, tire pressure monitoring, mobile payment, etc.。

In the construction of the IoT ecosystem, Bluetooth low energy is indeed the best choice, and its advantages are also obvious. Due to low cost, low power consumption, high-speed transmission, and the widespread popularity of mobile terminal devices, more and more smart homes, smart portable devices, medical and IoT development are driven by the National Revised Plan Guidelines. Since the construction of smart cities strongly uses the Bluetooth low energy communication protocol, the prospects of Bluetooth low energy are very large.
