true, but the transmitting radio will retransmit frames that don't get ack'd by the receiving side regardless of what transport protocol is being used (it happens at layer 2, TCP/UDP packets start at layer 3). The number of retransmits varies based on the vendor, but a typical value is 4 retransmits before the frame is dropped.

this means that even UDP packets that are dropped on the wifi link will be retransmitted (at least a few times), just with a little delay.
