Apple's iBeacons, an indoor positioning system that can detect nearby devices to optionally push promotional marketing messages, has been picking up considerable steam lately. For instance, such brands as Major League Baseball and Apple itself have implemented the system, as did various retailers, theme parks, grocery stores and even car accessory makers.
According to BEEKn.net, Apple has now released detailed specification for the iBeacon platform. Released through Apple's 'Made for iPhone' (MFi) initiative, the documents are apparently separate from Apple's main Bluetooth MFi specification..
