That doesn't eliminate the problem of interference from all of the other networks on the same channel (or on the neighboring channel that shares part of the spectrum), which are all using omnidirectional antennas. It can help, certainly, but 570 Wi-Fi networks in one ballroom is going to be hell on any network chip trying to sort through all the noise.
- jokermatt999 16y agoClearly the solution is to stick a Faraday Cage in between the audience and the stage. Seriously though, I know very little of these matters, but it does seem like there should be some sort of solution developed for them with the frequency that these issues keep cropping up in major tech demos. It seems embarrassing that companies that are supposed to be innovative and great with technology are being stymied by the lack of WiFi.
- bbatsell 16y agoI am rather surprised that they (seemingly) didn't use a 5GHz 802.11n network. N suffers from some reliability issues as well, but the channels are much more spread out and much less utilized (the MiFi doesn't support it, last I checked), so it theoretically wouldn't have degraded nearly as much if they had used a high-mW antenna to try to cut the distance issues 5GHz suffers from.
- herdrick 16y agoNo, I'm including all the antennas in that - why not use directional ones for all the networks in the room to keep the stage free of extra networks?

- bbatsell 16y agoBecause Apple had control over, maybe, 10-20 APs in the room (and those almost certainly only constituted one mesh network). The 569 other networks were from devices controlled by journalists and other attendees, the majority of which were MiFis (according to Jobs), which don't even have ports for external antennas.
