I understood (IP) from the original post and was suggesting a way to get an estimate as we don’t have another way to calculate that I am aware of. The PTP 650 minimizes latency and jitter for high-priority Ethernet traffic by fragmenting Ethernet frames before transmission over the wireless link. The fragment size is selected automatically according to channel bandwidth and modulation mode of the wireless link. Fragments are reassembled on reception, and incomplete Ethernet frames are discarded. What latency are you targeting?
