This is the most descriptive article that I've found on the MB set up.
The bottom of the article has links to all of the device specs which are Public knowledge.
Unfortunately full of inaccuracies too... but at least he makes it easy for people to find the FCC filings
The model xBRV4 device functions as part of a wireless location system. It includes circuitry
providing a proprietary wireless system as well as ethernet connectivity to the rest of the
infrastructure equipment. It is designed for and used by a single customer in a large amusement
park setting. This application is for the approval of a single radio that transmits at 2482 MHz
occupying a 1 MHz wide channel. Normal operation transmits data in approximately 200 uS once
each second. The device will only be installed by qualified installation personnel.
As for 200us once per second, this screams beacon query to me.
Assuming the band utilizes the nRF24LE1, the configuration would be the following:
1Mbps data rate (correlates to 1MHz wide channel per datasheet)
Deducted from what's stated in the Nordic datasheet, stated transmission times in the FCC doc, and ToA calculations for the NRF24LE1. Modulation is always GFSK. It's a turnkey RF SoC and the on air protocol is already defined. The nRF24 plus series radios can only be configured for 250kbps, 1Mbps and 2Mbps. 250kbps seemed more likely but it doesn't coincide with the timing they stated as ToA would be over twice what they stated for even an empty packet. Much longer with a payload of course.Where are you getting the data rate from? The data rate depends on the type of modulation used. Also, a 1MHz channel does not use the entire 1MHZ. There is a safety buffer on both sides so it doesn't interfere with adjacent channels. If designed for weak signals there will be a very low data rate, nothing near 1Mbps. There will be maximum error correction overhead plus you'd want as much energy per bit (i.e. less bits for a given unit of time).
With the higher crowds this week are issues still persistent at the Fastpass+ entrances? Are there still queues setup outside of the Fastpass+ queue?
So, I just got back from WDW. We used FP+ at MK, Epcot and DHS. We did not have more than a marginal wait at any attraction at Epcot and DHS (and at Epcot we did Soarin'/TT/Maelstrom in one day due to the "glitch" in the system), comparable to paper FP. Never more than a few people at the first scanners.
What "glitch" is that?
There was a day or two about 1-2 months ago where the restrictions at Epcot and DHS were not present. It happened after they updated the website for FP+ and then they fixed it.

Yeah, I just keep hoping that, when they add more FP+ after the first three, we'll be able to reset our tier limits and get another tier one option out of the list. Of course, that requires there being anything tier one available after you've used your first three passes, so on busier days that's probably a non-issue.

Thanks for the info. I think most of us suspected that the lines outside the FP entrances would diminish, glad to hear that they are.So, I just got back from WDW. We used FP+ at MK, Epcot and DHS.

In MK, we had some short waits at Splash and BTMRR at the entrances -- maybe 10-15 people but nothing like the snaking lines I've seen posted on here. There was roped queues set up at the FP+ entrance, which were only maybe a third used and not visually intrusive. After getting through the first scanners, we rushed through the (empty) indoor queue and got on the rides relatively soon. I didn't see much of a difference compared to paper FP+.
The one line we did get was for Space yesterday. It rained pretty heavily and we had Splash FP+ but it was shut down. So we went over to Space around when the rain stopped and there was a noticeable line of about 30-40 people outside of the first scanner for FP+. The line moved quickly though and once we were inside we got on quickly. I would say we waited about 15-20 minutes from getting into the line. My guess is that other people were like us and used our "use on any ride" FP+ from Splash to go to a working Space which drove up the line for Space.
Question: if you are at DHS or Epcot and you have a FP+ for a "tier 2" ride that shuts down and can use that FP+ on "any ride", can you use it on a "tier 1" ride? Example: you have a FP+ for Nemo at Epcot, Nemo goes down, can you then use that golden "use on any ride" FP+ to go on Test Track?
Also, more general, can you use that "go on any ride" FP+ to do a repeat ride? Like you used FP+ for BTMRR, then you go to use a FP+ for Splash but it is down. Can you then use that Splash FP+ to go on BTMRR again?

This an issue that absolutely bugs me. People are so impatient to get on when it's not their time they hold things up for those of us whose turn it is.caused by someone trying to get on twice or before their time.
