What is BLE communication? How does it work?

Bluetooth Low Energy (BLE) is a wireless personal area network technology for short distance data transmission. As the name hints, it’s designed for low energy consumption and cost, while possessing a communication range similar to that of the regular Bluetooth.

BLE communication consists of small packets of data and broadcasts at a regular interval by Beacons via radio waves. iBeacon standard calls for a broadcast interval of 100 ms.

Minor: a more detailed or minute information. For example, this beacon is located in aisle 2.

Tx Power: TX power refers to the strength of the signal that is exactly 1 meter from the device. TX is used to determine proximity of devices from the beacon.

How does iBeacon work?

A beacon with iBeacon protocol broadcasts a serial ID number which is then used by the corresponding app in the user’s smartphone to return results. iBeacon features a standardized format for BLE advertising in which, every data packet contains 4 pieces of information:

Unique Universal Identifier (UUID): It is a beacon’s general information. For example, the name of the person/business that the beacon belongs to.

Major: the beacon’s spatial information. For example, this beacon is employed in the aisles of store #9.

What is the history of iBeacon protocol?

iBeacon was introduced by Apple at the Apple Worldwide Developers Conference in 2013. In the same year, experts wrote on how iBeacon can help the retail industry by simplifying payments and enabling other on-site offers. In December 2013, Apple activated iBeacon in its 254 US retail stores. Ever since iBeacon as experienced an upward trajectory path.

What is iBeacon protocol?

iBeacon is a protocol developed by Apple, that enables smartphones to scan for beacon signals in the range and display the corresponding content. Minew SDK is an easy way to enable location analytics and proximity marketing through BLE networks.
