"Theoretically, there's no limit to the distance, as long as you've got line of sight."
WRONG - NAV is the temporal limitation in 802.11
The big question is how did they achieve the MAC layer Acknowledgment within the ack_timer.
Richard is right if he means the waves will propagate very long distances. But, the 802.11 machanism needs to receive the MAC layer Ack within a time period(NAV). The farther the 2 devices are apart, the longer it takes the waves to propagate causing a delay in time. This is the limitation.
What was done by the 125mile crew to account for the Ack delay? ..did they modify the ack_timer?
