Perhaps not so offbeat. Though bandwidth and radio don't go too well together normally.
Know some guys here in Australia that are doing extremely accurate timing with wireless, not for timing's sake but to measure movement in dam walls and other infrastructure. Kind of like a localised GPS. They have some very neat and accurate stuff. Had a play with some radio foo and managed to get about 880ns + air time on bit to bit from tx to rx but haven't quite figured out how to get super low latency yet. I think there may be a product in there for wireless PPS dissemination for accurate timing to a cluster like the guys do with the dam walls but I'm not sure if people really need much more than what ptp can already do. --Matt. _______________________________________________ Beowulf mailing list, [email protected] sponsored by Penguin Computing To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
