Bluetooth beacons refer to the devices broadcasting signals that are heard by nearby smart devices. These beacons are matched with an app, Physical Web browsers or Apple Wallet Pass, thus businesses deliver contextually relevant information and content to users at specific locations.
The beacons are fully supported by the beacon of Apple and Eddystone of Google, thereby making it easy for developers of iOS and Android to integrate the proximity services and to fully realize the physical web potential.
Beacons can simultaneously broadcast two iBeacon signals in association with Eddystone signal. Thus, it allows businesses to broadcast to both iPhone users, WeChat users and support contextual Eddystone attachments, telemetry data and Physical Web URLs.
Bluetooth beacons are very helpful. They enable customers, industrial environments and businesses through “proximity-aware applications”. End customers benefit through tailored offerings and instant coupons. Businesses benefit through visibility, thereby improved increased loyalty and customer buying habits.
Industrial companies benefit through utilization and improved asset monitoring. There are endless possibilities and beacons are meant to transform the entire world. However, knowing how the beacons are standardized and how the packets of advertising work is important. Bluetooth beacons do not adhere to any particular standard. They can be referred to as formalized formats or Pseudo standards for beacon applications that is headed by a group of companies or a large provider.
Today the “pseudo-standards” having high momentum are:
- Apple’s iBeacon;
- Google’s Eddystone
These pseudo-standards employ the methodology of BLE broadcast of advertising on 37, 38 and 39 BLE’s channels so that the Wi-Fi traffic conflicting is avoided.
Each pseudo-standard employs the BLE advertising structure to embed their data and formats. This packet is sent on the advertising channels with each beaconing device so that a BLE receiver picks it up. The scanner determines the content of the packet as it is relevant and decodable and takes relevant actions such that:
- The data payload, within the packet of advertising is structured in type, length and data.
- The length field represents the subsequent data fields and type as combined size.
- The field type designates if the data is a service UUID, a name, a URI- Universal Resource Identifier or one of the many defined types of data and
- The packet data is the place that the beacons take a step further in defining the data field inside the sub-structure to determine the pseudo standards.
