Extensive Guide to Bluetooth Low Energy (BLE) Beacons

What are Beacons and Why Should I Care?

Beacons are devices that broadcast signals at a certain interval. In other words, Beacons allow applications to understand their location on a hyper-local scale, and sends signals to users based on the location. The uses of beacons in the real world are extremely diverse and endless. They essentially bridge the online and offline world while gathering invaluable data.

Beacons and proximity are most commonly used for:

indoor navigation
asset tracking
employee tracking
keyless access
proximity marketing
and many more!

What are Bluetooth Low Energy (BLE) Beacons and How are They Different?

BLE beacons are, as the name suggests, beacons that use Bluetooth Low Energy technology. Just how much of an impact does this have?

Cost: This technology enables 60–80% cheaper cost of operation.
Power Consumption: 50–99% less power used means the average beacon can last up to 2 years, or even 5 years with our Beacon.
Application: BLE technology is perfect for beacons since applications only require minimal periodic transfers of data.

Eddystone and iBeacon, Which One is Better Suited for Me?

Before we go any further, I’ll provide a simple explanation of what Eddystone and iBeacon are: Eddystone and iBeacon are communication protocols. As mentioned earlier, beacons send out a Bluetooth signals at certain intervals, and the communication protocols describe the format that makes up the signal.

What does all that mean?

If none of that makes sense or is of interest to you, I will simply sum it up:

iBeacon is simple to implement, has more documentation, but less features.

Eddystone has more features and sends more information than iBeacon, but it is more complicated to integrate.

BLE Beacon Use Cases

Let’s face it, hearing about beacon specifications can get a bit dry sometimes; you want to see some real world examples and how you can benefit as well. We’ll go through specific use cases in retail, events, and tourism. These aren’t even all the uses cases, even the wifi baby monitor at Comfortcam have it.


Retail is probably one of the most mature and fastest growing industries that are using beacons today. Business Insider predicts that beacons will directly result in over $40 billion in US retail sales in 2016. Beacon technology is a great opportunity for retailers to see what items customers are most interested in and plan their store layout accordingly, heck they’re even on some coolers now.

Here are some ways you could use Bluetooth beacons in retail:

Send customers offers and discounts while they walk by a product.
Optimize the flow and service of a store by gaining data regarding time and day of the week vs number of people.
Detailed information regarding things like parking or assistance.

Carrefour gains 600% more app users by using Kontakt.io beacons.


Beacons power events internationally, use range from small meetups to large conferences and expos.

Here’s a list of some uses because people seem to love lists:

More efficient networking, there are apps that indicate which LinkedIn contacts are nearby and which of them have shown interest in certain exhibition stands.
With beacon-enabled alerts and updates, you can keep your attendees informed in real time.
Driving attendee engagement: When attendees enter the venue and their smartphone will detect the beacon for that session and they will receive a prompt to “Join the Conversation” within the app.


Proximity helps create an interactive environment in places like museums, completely revolutionizing how they guide, educate, and tell stories.

Here are some neat ways to use beacons in tourism:

Ability to take self-guided tours.
Receive maps, additional information on things like points of interest.
Some venues implement beacons in the restrooms to show relevant information about future events or even advertisements.

Main Considerations

If you’ve read/skimmed this far, you must be interested. So what else should you consider before going into the proof of concept stage?


If you’re deploying a large amount of beacons, you must have the right set of tools and communication. You must ask, how the beacons are configured or labeled during deployment? Are they continuously updated as the business purposes for the beacon changes? If you’re in some expert tips, feel free to check it out.

Fleet Management and Coverage

Management will need to be considered during deployment. One must routinely check on: missing/stolen beacons, the indicators regarding battery life, and categorization of the beacons.

The coverage or range of beacons vary largely depending on the environment. Fixtures, walls or even other signals may disrupt the coverage. It’s hard to estimate what the spread in beacons are, but we’d love to try.

Beacon Security

Beacons are now emerging as a gateway to complicated financial interactions, so now there are incentives for someone to gain access to your beacons. The Eddystone communication protocol is already secure, but iBeacon is vulnerable to piggybacking, cloning, hijacking and cracking.

Lucky for our users, all our beacons have Kontakt.io Secure, worlds only suite that protects you against all the security threats.

Beacons Solution Provider Checklist

Alright, so now you’re thinking, ‘beacons are interesting, and I’d love to juggle the idea of a proof of concept’. We got you.

As a quick disclaimer, we don’t provide solutions we just manufacture the beacons. We do love playing the match maker, we know the industry better than you, so just shoot us a message.

Here are some things you need to look for in a solution provider:


Does the provider have a management tool that tracks where each beacon is as well as their current status (battery depletion or moved), with notifications?

Pricing, how much does each beacon cost? They can cost anywhere for $20 to $150 per beacon (ours is on the lower spectrum).


How are the beacons configured for your use?
What is the turnaround time for installations (deployment)?
Security, if they are not using Kontakt.io beacons, what kind of security measures are they taking?
