Ah thanks, that explains it. So i assume it won't work unless something else is also transmitting?

- Polylactic_acid 7y agoI'm struggling to find a single use case where this would work. You need 2 wifi APs, regular wifi usage and a device where such aggressive power saving is more important than working reliably.
- dev_tty01 7y agoActually, just 1 AP. It can backscatter signals to the AP from other wifi devices such as phones. Regular wifi usage is not a constraint in most applications.
- Polylactic_acid 7y agoDoesn't it say that it has to change to a different wifi channel?
- airstrike 7y agoAutomated factories
- generatorguy 7y agoIf you have a factory you run wires to the things that are important for your factory to run.
- airstrike 7y agoCollecting data from those processes is arguably easier done with Wi-Fi
- generatorguy 7y agoEasier but factories are unfriedly to WiFi with all the giant metal structures, high,medium,low voltage power cables, emi noise from motors and VFDs, etc. WiFi is more difficult to troubleshoot whereas Pretty much anybody can use a cat5 cable tester. And there are already cable trays and raceways going to all of the different equipment because it uses electricity. So in the industrial processes I’ve been involved in radio was only used outdoors and when communications cable would have had to have been strung up on poles. Reliability and ease of troubleshooting are characteristics industry values more than labor saved running cat5, in my experience.
- wtallis 7y agoIt sounds like this technique won't work for realtime communication, but that doesn't rule out much of the IoT use cases. As for the 2 APs requirement: when's the last time you've been in range of just one AP, with the 2.4GHz band otherwise quiet?
- joshspankit 7y agoI don’t see anything that says you have to control both APs. Almost everyone in populated areas lives within range of a few neighbour APs.
