iBeacon is generating lot of buzz nowadays. With a rich ecosystem of 200 million Apple devices that have ability, this seems to be poised to take off in a big way. The Wired article articulates 4 main areas where it can take off.
There is still confusion whether it is hardware dependent or it is more of a protocol (software enabled).
Andriod seems to be playing catchup with this since there are both hardware and software lag behind this. This has potential to be cross platform since it is built upon standard BLE (Bluetooth 4.0) standard.
The article aims to dispel some myths and bring some clarity.
Strictly speaking, iBeacon is a protocol that lets developers harness the latest Bluetooth Low Energy technology in their apps, but the term “iBeacon” has quickly been adopted for referring to physical things: the nodes in this new wireless network. Effectively, anything that has the latest version of Bluetooth can function as an iBeacon. In some cases, that can mean a smartphone. Google recently jumped on the Bluetooth LE train, baking it into Android 4.3. Apple has been building it into their devices since the iPhone 4, meaning that every iPhone from the last two years is essentially an iBeacon in itself.
