BAN

Body Area Network.


Band

A range of frequencies used by a technology for communication purposes. For example, the 2.4 MHz band is used for Wi-Fi and Bluetooth communication.


Beacons

Low-cost devices that communicate with smartphone apps indoors, without the need for GPS. Beacons use BLE and are key enablers for the smart retail category, triggering messages as consumers pass through locations or near products.


Big Data

Data sets so large that they cannot be used with traditional database tools. Big data often requires massively parallel computing resources to access, curate and analyze. Big data analysis techniques are crucial to such disciplines as spotting business trends and simulation.


Bluetooth

Short-range wireless technology standard which operates on the 2.4 MHz band. Bluetooth can be used for sending both data and audio, with popular uses including wireless headsets and cordless keyboards. Bluetooth devices can be set up with different hardware profiles to help perform specific tasks, for example audio adapter, audio headset, serial, and keyboard profiles.

Bluetooth 4.0 (BLE)

The latest iteration of Bluetooth, also called Bluetooth Low Energy (BLE). It offers lower power use for portable devices and new profiles including Bluetooth Mesh, a Bluetooth topology that allows devices to be connected together, sending/repeating commands from the hub to any connected device. Apple’s iBeacon is an example of a BLE application, and BLE as many potential uses for IoT devices.


Bluetooth LE (BLE)

Body Area Network (BAN)

A wireless network of wearable computing devices and physiological sensors, which may even be embedded inside the body. A BAN may also be referred to as a WBAN (wireless body area network) or a BSN (body sensor network). A key use case for BANs is e-Health applications.
