Well, I have admitted to not being tech savvy about 324 times here. So, you probably have a point. ... But I also think you are much too quick to jump to Disney's defense when you know the tech better than probably anyone here (or almost ... where's @
Lil Fort ?)
I'm plenty critical of Disney and have little reason to defend them. That said, I also strive very hard to avoid playing 'jump to conclusions' - I'm not perfect, but I am very conscious of trying to avoid that. In my profession, credibility is everything. There are no points for jumping ahead and being right 'some times' - if you are wrong once, that's enough to hurt everything you do. I won't make a claim or put my name behind it unless I am VERY confident in it.. otherwise I will explicitly state my level of confidence in the info and refuse to back it blindly. Some execs hate that.. others love it because they can trust me blindly.
And let's also be blunt, technology like this morphs and has the ability to change into a much different product than the basics that Disney is allegedly starting with.
I agree - which is why I keep telling people to not get hung up on '3 FP+ reservations' or what the groupings they saw in testing are. I fully expect those things to all change, if not by launch, but as the system evolves over it's toddler years. But there are some things that are much harder to go back on.. and Iger's willingness to throw down a gauntlet along those privacy lines make those even harder to regress on later.
Speaking of the technology, Iger's use of the phrase 'is not GPS-based'' concerns me. Again, I don't know the specifics of the tech. I do know there is a difference between enabled and based. Disney must have had a good reason for using that particular wording, especially because we know the MagicBands have 2.4 GHz antennas in addition to the two RFIDs. Maybe you or someone else can help with the understanding of this.
I wouldn't read into it. The core concept is.. a GPS device looks at reference points and determines 'where it is'. The device itself figures out the location and knows what it is. The MagicBand device doesn't appear to be that advanced. The band doesn't need to know where it is (what is it going to do with the info??).
A phone uses that type of info to report back to an application to say 'Hey, the guy using your software is at lattitude XYZ, and longitude ABC'. The phone may also just be generically logging that info (which is what Apple got in trouble for) for long term stuff. But the phone (the GPS enabled device) actually knows where it is, and can use that, or report it to somewhere.
The bracelets would be much dumber.. they don't need to know where they are, but rather say 'hey I'm here!'. It is likely broadcasting some identifying code all the time. More of a 'Hey, I'm ID=24354 and I'm here!!' type of broadcast. The intelligence is not in the band, but in the receivers around the park. The receivers see the broadcast.. and say 'ok, I'm node Castle3, I just saw tag ID=24354 broadcasting in my area.. so log that'. Now the system knows where YOU (within a zone) based on your chatty bracelet. The bracelet doesn't know where it is, nor does it really care. The park network/system logs whenever a new reciever sees your chatty bracelet. Now it knows you've moved to a new zone. But more importantly, it can be used to say 'Hey, I'm node Castle3, and I see 2,500 different IDs broadcasting in my zone in the last 60 seconds'. Using that type of info, Disney can in effect monitor and track crowd levels and crowd movements in an automated fashion.
Or another example.. to show the brains is not in the bracelet but in the receiver would be picking up a guest at range. Imagine your chatty bracelet is going off as you ride through IASW. It's just chatting all the time. But as the ride designer, I design an antenna that only picks up the bands in a very specific area. When I 'hear' a chatty band going off, I know those IDs are in my target area. Then the attraction says 'Ok, I see 10 IDs coming into my show scene... filter that list for all IDs that have some personalization options enabled, then pick one of those IDs to customize the show.. ok, I picked ID=2344, now go lookup the personalization preferences for that person and show the custom show scene'. The ride system knows where the target area was.. and maybe has another antenna to know when you are in the sweet spot.. and then fires off the show element.
I've speculated the band may have logic to know when to turn itself on or off based on broadcasts in the WDW area. But that is based on my design theory, not anything specific released from Disney.
