Bluetooth Low Energy

BLE Beacon Technology

Bluetooth Low Energy (BLE) is a part of Bluetooth 4.0 (2010) specification and uses bluetooth signals to communicate between low energy consuming bluetooth beacons and Bluetooth enabled smartphones.

An Introduction to BLE

As a low power-consuming Internet of Things (IoT) technology, BLE is highly capable of short-range wireless communication. Bluetooth Low Energy was developed as Wibree by Nokia in 2006, specifically as a low power-consuming wireless standard, in contrast to Bluetooth and Wi-Fi, which provide high data transfer and consume lots of power. Later in 2009, when Bluetooth 4.0 specification was launched, it became BLE.

BLE beacons, smart BLE devices, are popular for PAwR (Periodic Advertisement with Response) and bidirectional communication with BLE-enabled devices (Bluetooth 5.4) such as smartphones.

In this digital age, BLE finds many applications in smarthomes, indoor navigations, wearables, inventory management, periodic advertisement, retail operations, supply chain and logistics, etc.

Interconnected Objects

Low Power Consumption

BLE technology is popular for low power consumption as it only allows a small amount of data transfer. BLE beacons have a battery life of 3-5 years.

Process Optimization

No Interference

BLE technology uses 2.4GHz frequency for communication and there is no interference from metallic surroundings, unlike RFID technology.

Insights and Analytics


BLE technology is versatile as wearable devices, BLE beacons, smartphones, etc. easily support BLE technology.

Enhanced growth

Small Form Factor

BLE technology can be easily integrated with small wristwatches, eyewears, fitness trackers, etc.

BLE Beacons

BLE beacons are devices that are used for broadcasting low energy signal periodically, based on Bluetooth (LE) protocol. Although beacons and tags are used interchangeably, Bluetooth beacons find completely different applications than a BLE tag.

  • Used for advertising
  • Works on RF37, 38, 39 channels.

BLE Gateways

Bluetooth Low Energy gateways are developed on Bluetooth 4.0 specifications and act as the bridge connecting two or more BLE gadgets. BLE gateways allow the connected device to share data over the cloud and communicate. The low energy consumption allows for long battery life.

  • BLE Wi-Fi gateway
  • Wi-Fi to BLE 5.0 gateway
  • BLE 5.0 gateway

BLE Tags

BLE tags are used for identification and tracking needs. When attached to an asset, the BLE tag sends Bluetooth signals to nearby Bluetooth enabled receiver and establishes a secure connection. The receiver or reader, which might be a smartphone, can decode the data from the BLE tag.

  • Used for data transmission
  • Works on 37 RF channels in 2.40-2.48GHz ISM bands.
  • Ideal for identification

Key areas of Bluetooth Low Energy applications

BLE has been successful in carving out a niche for itself, just somewhere between QR codes, NFC and RFID.

The low energy consumption and non- requirement of a complex infrastructure for implementation, make BLE perfect solution for retail businesses, schools and libraries, healthcare, transportation, asset tracking, tool tracking in manufacturing sector etc.
