Carry a beacon (or a bunch of them) with you into a shop and the store will recognize you the next time you enter. That's handy! It's like a cookie that you physically bring every time. ~ Or, in other words, no thanks.

Boy oh boy, this technology is going to run into a lot of misinformed speculation like the above. I know that YOUR LOCATION DATA is super important to you and all the technology ghosts are trying to steal it from you but that is not how this works.

Really cool technology. I think the really hard part is 'What is a good interaction?' Clearly the offer isn't too useful, but the hospital one seems good. In general, I think 'help me find stuff' and 'notify on exit' will be the dominant modes of beacon interaction. What do you all think?

It was surprisingly challenging to come up with just those two examples to be honest. I don't think we really know what the killer location-based notifications are going to be yet.

> * In fact, referring to these devices as just “Beacons” is a bit funny, considering no one was talking about Beacons before iBeacons existed.* Well...I recall unpaired advertising events in the Bluetooth 4.0 Low Energy Spec back in 2010 - way before Apple ever got involved.

I was doing an internship at a big semiconductor company the summer announced iBeacon. They had something very similar in the works (presumably started about the same time as Apple), and called them beacons - they certainly worked by exactly the same method.

Absolutely ... this wasn't an entirely new "invention," although Apple's technique of cramming their metadata in the spec is definitely novel, although nonstandard.

Mmm, I'm not so sure. If you read the Bluetooth 4.0 spec [1], it's very obvious on page 1047 (numbered 801 in the pdf) the exact advertising format, with its block of bytes for sending data. Sending a UID would be exactly what you would do, as a first approximation. There are actually much more interesting schemes that can be used - say if you don't want your competitors to be able to derive any information of their own from your beacons.

As an iOS developer who has spent the last 9 months making beacon enabled things for my employer, I personally think beacons are shit. Some of my findings over the last 9 months:

- Estimated battery life was estimated very poorly.

- Nobody likes things they didn't ask for getting sent to their phone.

- Indoor navigation that relies on iBeacons only is going to shoot you in the foot. I recommend www.indoo.rs as the only solution that got close to what we needed (though it's still pretty darn immature).

- Speaking of indoor navigation, you need a ton of points to do it well (whether that's beacons or wifi routers, you decide).

- Using beacons for granular location-aware uses might as well go out the window if you're looking for accurate and precise readings around ~1-3ft.

- Did I mention power yet? All of the beacons we started with around 9 months ago have dead batteries. Even with conservative power modes set. The only beacons that don't are RadBeacons USB sticks that plug into wall outlets. And that's only because they don't have batteries.

I really, really want them to be good. But they die too quickly, and don't provide granular signal data. Hold the phone between you and the beacon and get a decent signal, then turn 180 degrees so that you are between the phone and the beacon. Apparently you've moved 45ft.

Nobody would use beacons this way. They don't have to -- your cell phone, if it passively scans for Wi-Fi, will check into the local access points for you.

(Disclaimer: I work for Estimote) Indoor location works much better if you utilize data from other sensors in the phone (like accelerometer etc) and apply machine learning to make better sense out of all the signals. I'd suggest you take a look at our SDK that works surprisingly well even with just 4-5 beacons. You can also map your room with our iOS app by just walking around it. You can find it here if you're interested: http://estimote.com/indoor/

We've also implemented some adaptive algorithms to optimize the battery life in our beacons, so with conservative settings they should work for 5+ years now.

How do you manage 1,100 beacons at once App side?

I thought Apple limited you to 20 region monitoring locations at a time, or are the beacons treated differently? Just logic around which 20 you're looking for at any one time?

Beacons are being used as a micro-surveillance tool [1,2]. And that is the only prominent use they have found, among all the ones listed. Interestingly Gimbal, is a Qualcomm company or rather was a Qualcomm company as it was spun off [3]. Gimbal also had $5 beacon giveaways [4]. Gimbal had embedded its beacons in phonebooths in Chicago, LA and New York [1, 2].
