Apple has released an iBeacon specification through its MFi program, as noted by Beekn. If manufacturers meet certain established criteria, they will be able to brand their devices with the iBeacon name. In addition to bearing the name, official iBeacons will broadcast Bluetooth LE to Apple’s standards. Applying to the program is free. Though the specification will give Apple more control over the iBeacon name, it’s notable that there are no restrictions which would make an iBeacon incompatible with other phones, such as Android phones.
