Different Approaches to Using Wi-Fi to Determine Location by Ruckus | Indoor Maps | Scoop.it

Indoor location technologies have received a lot of attention in the mobile world recently, with Apple's acquisition of WiFiSLAM, Google's increasing support for indoor locations in Google Maps, and Microsoft’s expansion of indoor maps in Bing (source: Seeking Alpha)

By knowing where clients are, companies are able to help them get wherever they need to go, make the network experience better for them, use data from their location to optimize their experience, offer and tell them stuff along the way, and tell them stuff along the way.

As Smart Wi-Fi solves the capacity, reliability, and performance problems on Wi-Fi infrastructures, enterprises and carriers have become keenly interested in offering LBS services to their customers and their' clients.

 

Different Approaches to Using Wi-Fi to Determine Location

Think of Wi-Fi location as indoor GPS. Wi-Fi-based positioning systems are used where GPS is inadequate due to various causes including multipath and signal blockage indoors. Though the Wi-Fi protocol fundamentals haven’t changed much in the past few years, the ecology of Wi-Fi location services have completely flipped. Now that almost every human on the planet has multiple Wi-Fi-enabled devices—in pocket, on hip, in hand, on desk—businesses from retail and hospitality to healthcare and education are looking to capitalize. With that shift, new techniques to improve accuracy are emerging, user behavior and expectations are changing, and new location service models are being built.

Wi-Fi supports a number of different location approaches today, but signal strength localization based on signal strength (using multiple received signal measurements to calculate the source’s location) and RF fingerprinting (collecting on-site RF data to map signal measurements to locations) have been the most common. Most of the focus on location whas been asset tracking or locating clients and rogue APs.
