Isn't this just another spin on NFC?

skierscott• 13 years ago

With greater range. NFC has a practical range of about 4cm; iBeacon has a range of about 10-20m.

NKCSS2• 13 years ago

Ah, then it must be Bluetooth Low Energy.

hrktb• 13 years ago

Bluetooth low energy yes, but I'm not sure it's fully available to applications. iBeacon is more specific and dedicated to location calculation (it's part of core location)

karthikv• 13 years ago

This gigaom post has more details on iBeacon: http://gigaom.com/2013/09/10/with-ibeacon-apple-is-going-to-...

ZeroGravitas2• 13 years ago

Hmm, reading that after the estimote pages makes it seem that the gigaom post is just guerrilla marketing for estimote, that's trying to hijack the Apple publicity.

Have Apple actually stated anything public other than the word "iBeacon"?

Googling around I just find the same rewritten PR material all about estimote, not iBeacon specifically.

jimiasty4• 13 years ago

Hey, this is Jakub from Estimote.

We have been working on wireless Bluetooth Smart beacons long before Apple made it part of their Core Location API and called iBeacon.

If you would like to learn more about Apple iBeacon you could check it here: https://developer.apple.com/library/ios/documentation/CoreLo...

Our API and BLE beacons in general are explained here: http://www.estimote.com/api

iBeacon’s range is 50 meters (typical Bluetooth range), or 2,500 square meters.

That's some weird antenna right there. Assuming it's omnidirectional with a 50m range (radius) then it would cover more like 7,800 square meters.

The range of Estimote’s beacons is 50 meters, but the recommended range is 10 meters. If you go with the recommendation, you need 1 Estimote beacon for every 100 square meters.

More like 314 square meters.

ISL• 13 years ago

2,500 square meters

I'm not sure it's a weird antenna. Looks like the author took 50^2 (square with edge length 50 m) instead of \pi 50^2 (the traditional interpretation of 50 m range).

jmmcd• 13 years ago

> you need 1 Estimote beacon for every 100 square meters.
More like 314 square meters.

But you can't pack circles tightly -- you have to use hexagonal cells.

For people pursuing this, it's worth looking back at the successes and failures of Jini, from both technical and market perspectives.

pohl• 13 years ago

...it's worth looking back at the successes and failures of Jini

Could you delve into the relationship between the two? I haven't read much about iBeacons; are they based on the "tuple space" model, or was Jini initially intended for the same market?

melange3• 13 years ago

What specifically has Jini got to do with this?

projectileboy3• 13 years ago

Jini was trying to solve the same sorts of problems. I mention it because when we look at a new technology, it's often instructive to look at older technologies that were trying to solve the same (or similar) problems. In particular, it's helpful to look at why they succeeded and why they failed.

For example, the "web services" community would have been well-served by looking at the successes and failures of CORBA, since the web services folks mostly replicated all the mistakes of CORBA.

ZeroGravitas2• 13 years ago

This is informative:

Doesn't seem like there's a standard API yet.

Tyralen• 13 years ago

There's another company with iBeacon style sensors that I've seen at ArtPrize in Michigan called GeLo: www.gelosite.com

adestefan7• 13 years ago

There is also Tile (http://www.thetileapp.com/) which is using them as a way of distributing the finding of lost things. It's an interesting concept, but something I'd never do.

justx1• 13 years ago

Here is a good article that describes some scenarios that provide a glimpse into iBeacon's potential:

outside1234• 13 years ago

Does anyone know if there is an open version of these motes? And what phones other than the iPhone support bluetooth low energy?

adestefan7• 13 years ago

See http://www.bluetooth.com/Pages/Bluetooth-Smart-Devices.aspx

The Galaxy S3 and S4 have home grown BLE stacks and Android 4.3 has finally announced BLE support in the stack so it should show up on Android phones that get the update (the hardware has been there for ages.) Blackberry 10 announced support this summer.

melange3• 13 years ago

It's worth noting that iOS devices themselves can serve as beacons - so, for example a payment terminal app running on an iPad can announce itself to nearby iPhones.

jimiasty4• 13 years ago

Hi, this is Jakub, Co-founder of Estimote (YC S13).

That's correct and any iOS device (iPhone, iPad, iPod Touch) could be turned into a beacon.

We have even developed a Virtual Beacon app you could already download from the App Store and simulate beacon and proximity: https://itunes.apple.com/us/app/estimote-virtual-beacon/id68...

If one wants to pickup the Virtual Beacon's signals programmatically then our API website could be helpful where we have included source code of few apps http://www.estimote.com/api

eddieroger• 13 years ago

I'm so glad this is out of NDA. My coworker and I rushed through our lunches at WWDC to play with this. The API is so easy, and possibilities of what it can be used with are so broad. The immediate massive downside is that it's iOS only. But, it's a relatively open spec, so porting some logic in a non-copied way should be possible.

adestefan7• 13 years ago

It should be completely doable in Android 4.3, but you'll have to do it via the Bluetooth API instead of a location API.

arpit• 13 years ago

Can someone tell me how this compares to something like StickNFind? https://www.sticknfind.com/

jimiasty4• 13 years ago

StickNFind or Tile are designed to be sticked to moving objects in order to estimate their location from owner phone.

Estimote is designed to be sticked to fixed location. Think about it as a lighthouse that is broadcasting its presence and location, so smartphones and other smart devices could estimate their relative location and get the context.

joezydeco• 13 years ago

So that implies that the app locating these fixed beacons needs some kind of data backchannel to understand what it's seeing? Unless you have a cached map of that particular store and it's beacons already in your device, right?

mentos• 13 years ago

I think its everyones dream to walk into a store, type what you're looking for into your phone and see how far it is away from you.

How cheap would these have to be in order to make them cost effective to put into every day product packaging?

And would too many of these near each other cause too much interference?

This would be a great way to cut the store out of the solution and just go straight from product -> customer?

jonknee• 13 years ago

I think its everyones dream to walk into a store, type what you're looking for into your phone and see how far it is away from you.

Soon you won't even need to go to a store, the things you want will be dropped off to your home or business...

mitchty• 13 years ago

You mean like amazon prime? I'll admit amazon isn't always the cheapest, but with subscriptions and whatnot, its way nicer to have things mailed to me.

That said the environmental impact of shipped boxes may not be better overall. But damn is it convenient.

GFischer• 13 years ago

I believe the future in the short term would be something like BufferBox

http://en.wikipedia.org/wiki/BufferBox

"temporary parcel pickup station for packages ordered online"

https://www.bufferbox.com/

I want to do something like this in my country.

rada3• 13 years ago

I've implemented this as a hackathon project a month ago (an iPhone serving as a broadcaster and an iPad serving as a receiver). It's an awesome technology with a lot of promise but my one BIG gripe is the imprecision of RSSI. At home, the proximity indicator was somewhat accurate. At the office the proximity indicator was not accurate at all - half the time it would be good but the other half it would show the unpredictbale/interchangeable RSSI whether the receiver was at a yelling distance or a whispering distance. (Maybe due to signal interference)?

If RSSI cannot be relied upon, it severely limits the utility of iBeacons. A "binary" result (beacon found, beacon not found) can be useful but not near as useful as a reliable distance indicator. For example, my goal for the hackathon was to see if equipment in a lab could be activated by walking around with your phone. If the phone cannot tell that I am closer to equipment A than equipment B, then there is no point and moreover, we should not be referring to this new technology as "micro locations".

Having said that, I know of a company here in Minneapolis piloting iBeacons as indoor navigation (to find your way in a mall for example). I don't know if their technology works because they've found a way to ensure more correct RSSI readings, or if they are simply relying on the assumption that stores are far enough apart.

Osmium• 13 years ago

Since you've got some experience with it, do you have any idea how hard/easy it'd be to get an iBeacon working from a Raspberry Pi equipped with a Bluetooth dongle?

rada3• 13 years ago

I used Apple-provided bluetooth capabilities so my experience is probably not particularly relevant to Raspberry Pi, sorry. One thing to think about is battery life, unless you only need to pair the broadcaster and the receiver once. What I mean is, if you have a listener that is constantly scanning for a signal and doing some logic depending on the signal strength, you are bound to have battery life as your biggest challenge and potentially a deal breaker to any real use.

adestefan7• 13 years ago

It should be straightforward with BlueZ 5. Good luck finding documentation on how to do it though.

bmleon20022• 13 years ago

RSSI imprecision is just the nature of the BTLE. Bluetooth signals tend to bounce around in room that is full of objects, heavy metal blocks signals, etc.

To solve the problem, this can be accomplished by collecting an array of RSSIs and averaging them to get a more accurate result over time. Being said, for time sensitive use cases, it's pretty challenging to use iBeacons. Nevertheless, iBeacons has a lot of potentials.

I also think iBeacon will eventually dominate the proximity detection market. Here are 3 reasons: 1. Apple has a dominant smartphone market influence. 2. Apple released the iBeacon spec into the wild, and there will be more companies manufacturing iBeacons like estimote. 3. Google's BLE API is not that mature yet.

rada3• 13 years ago

RSSI imprecision inherent in BTLE is exactly the point I wanted to make. The marketing around BTLE focuses on "micro locations" but I feel that that's misleading given that in the real world, you cannot reliably get even approximate precision (let's say 5 feet) let alone micro precision. Human walking speed alone is enough to blow the whole "micro" concept out of the water.

Another sticking point for me is the battery life. The transmitters are touted as low energy, which they are, being able to transmit for 2 years on a watch coin battery is amazing. However, a transmitter is useless without a receiver (did the tree really fall...) and the receiver is going to be anything but low energy if has to continually scan and compare surrounding signals. Granted, my demo receiver app was as unoptimized as you can get (one day of coding plus I am not even an iOS developer) but at the same time, it didn't do much but look for signal, and it was chomping through battery at an alarming rate. It was ok for a 5 minute demo but I can't imagine real users would put up with this for long.

Given these two limitations, I have a hard time imagining wide adoption.

eddieplan9• 13 years ago

Besides Estimote, another startup that provides dev kit including Bluetooth LE Beacon and API is kontakt: http://kontakt.io

mietek• 13 years ago

Unfortunately, their pre-order link 404s.

cobrabyte• 13 years ago

They're back online. I had visited them yesterday and got 404s , as well.

zengr• 13 years ago

PayPal is building an iBeacon too for payments in store.

lcusack• 13 years ago

I have to imagine iBeacons could be more about the iwatch than the iPhone. I don't want to take my phone out of my pocket all the time to check for new notifications. I would glance at my watch.
