Aruba Networks Enables “Blue-Dot” Indoor Navigation With Beacons

By Greg Sterling

Aruba Beacon Navigation

WiFi provider Aruba Networks used to offer retailers and others “blue-dot” indoor navigation using WiFi triangulation. However Apple’s recent decision in iOS 8 to randomize the iPhone’s MAC address changed all that — and may have effectively killed WiFi as an indoor location technology.

Beyond this, WiFi is expensive and requires significant IT involvement. Beacons by comparison are cheap and don’t implicate IT infrastructure to the same degree.

Now, in an industry first, Aruba has developed viable indoor turn-by-turn indoor navigation using beacons and a process called “trilateration.” The company didn’t invent trilateration but to my knowledge it is the first company that has successfully implemented it in the real world. Trilateration is like triangulation except with beacons instead of WiFi or cell towers.

Aruba has a massive beacon deployment in the San Francisco 49ers Levi’s Stadium in Santa Clara California. The 49ers app delivers real-time, blue-dot navigation around the stadium.

Beacon trilateration hasn’t been successfully accomplished in the past, partly because there haven’t been enough beacons deployed in locations and because their low power system — beacons use Bluetooth Low Energy to minimize battery drain — hasn’t created strong enough or stable-enough signals to manage “blue dot” navigation.

(As an aside Indoor Atlas enables indoor, blue-dot navigation using geo-magnetic positioning but that’s a completely different technology — though it is beacon compatible. It’s not widely deployed however)

Aruba has developed beacons that can be plugged into walls in addition to running on batteries and can be managed remotely in the cloud at scale. This enables major public venues and retailers with hundreds of stores to manage the thousands of beacons required to deliver turn-by-turn indoor navigation.

You need a lot more beacons and beacon density to pull off trilateration. There are more than 1,000 beacons in Levi’s Stadium for example. …read more
