That makes sense. AirDrop rapidly switched the wifi radio between the network minis connected to and the adhoc network with the sending device. It’s effectively running at half speed with a clever trick.

Airdrops only problem is the proprietary nature of it but it’s a good solution that works very well. In the PC market, they still can’t get Bluetooth right. They never got Miracast right either. Microsoft half-asses everything they try which turns apples cool idea into the only way to do something.
