Not sure about that? In a UDP based ping it's fire and forget so wouldn't repeat, so would show as packet loss not increased latency.
Unless the physical layer is using more FEC and using longer "timeslots" to get to transmit the payload. But even that seems unlikely to cause major latency increases?
It's vanishingly rare for radio-based networks to actually rely on high level IP behavior for redelivery, as it's much faster to fix these issues on the single radio link than to wait for things to go round trip. The data link protocol typically has its own reliable delivery implementation that will result in multiple retries. This results in increased latency in poor network conditions. 802.11 behaves similarly.
