iBeacon to operate at 2.4ghz? Does no one at Apple see a problem with this? Not only does water resonate at this frequency to block any signal (think high humidity areas and outside venues where it may be foggy, sprinkle or rain), but a lot of businesses use internal comms and wifi modems on this frequency.
I would have picked anything other than 2.4ghz.
You are saying humid countries like Singapore, and San Francisco folks can't use BT headsets, keyboards and mouse ? What nonsense.

Why would Google want to copy something so limited when they already have geo-fencing and pay pass built in? Both are more robust and don't need any additional hardware to be built, maintained, installed and paid for. iBeacon is another Maps failure in the making.
Geofencing is inferior to iBeacons, especially in indoor environments. It is decidedly less accurate. iOS has geofencing *and* iBeacon.
Pay pass is just a vertical use case compared to a horizontal platform like iBeacons.
