Does AirDrop use radio waves?

Does AirDrop use radio waves?

2 Answers. AirDrop uses Bluetooth and WiFi to broadcast beacons and identify and negotiate a peer to peer mesh link. Since the WiFi radios are capable of multiple transmissions, they will hop and change channels based on the conditions at the time of the construction of the peer to peer mesh.

What is the speed of AirDrop?

With 802.11ac theoretical speeds of up to 1.3Gbps (but much slower in practice), AirDrop transfers could be very fast when done in a peer-to-peer fashion over a common Wi-Fi network. By contrast, NFC is relatively slow, topping out at 424Kbps, although Bluetooth 4.0 is much faster, at up to 25Mbps.

How do I know if my iPhone is 2.4 or 5GHz?

Your will see a list of your devices connected to your Airport. Tap the device you want, and then tap Connection. If you can see “802.11a/n” somewhere, it means the device is connected to 5 GHz. If you can find “802.11b/g/n”, it means 2.5GHz.
