Wireless LANs: from WarChalking to open access networks
TLDR
This work discusses the evolution of W-LANs from their current status of wireless termination of LAN services to a possible global infrastructure where the access networks become open to multiple operators and a vehicle of a win-win scenario, where both users and operators benefit from the new network architecture.Abstract:
This work discusses the evolution of W-LANs from their current status of wireless termination of LAN services to a possible global infrastructure where the access networks become open to multiple operators and a vehicle of a win-win scenario, where both users and operators benefit from the new network architecture. The idea of Open Access Networks (OANs) can go beyond wireless HotSpots and be generalized to a generic shared access infrastructure that fosters service operators competition and drastically reduces the cost of last mile coverage.The general concept of Open Access Networks is detailed, highlighting its difference with the more traditional model of vertical integration of the access network into the global service. About the OANs development, it is shown how to support the quick and smooth evolution of the infrastructure toward a widespread and reliable communication support.Business models are discussed by mentioning the different actors, the market organization and the different organization forms.The final part of the paper is devoted to technical challenges such as access control, security, privacy, roaming, resource exploitation and service differentiation. As an example of how to tackle these problems, we discuss a pricing technique devoted to resource management and billing support.In addition we present a simulation on how the OAN concept can speed-up the deployment of broadband access in a real case.read more

Continuous data optimization of moved access points in positioning systems
TL;DR: In this paper, a location-based services system uses WiFi-enabled devices to monitor WiFi access points in a target area to indicate whether a WiFi access point has moved relative to its previously recorded location.
Patent
Method and system for selecting and providing a relevant subset of Wi-Fi location information to a mobile client device so the client device may estimate its position with efficient utilization of resources
TL;DR: In this article, the authors propose a solution to estimate the location of a mobile device from a remote server by caching one or more WPS tiles in the WPS tile store on the mobile client device.
Patent
Location-based services that choose location algorithms based on number of detected access points within range of user device
TL;DR: In this paper, Wi-Fi access points are located in a target geographical area to build a reference database of locations of WiFi access points, and the location information is used to reverse triangulate the position of the detected WAP.
Patent
Server for updating location beacon database
TL;DR: In this paper, Wi-Fi access points are located in a target geographical area to build a reference database of locations of WiFi access points, and the location information is used to reverse triangulate the position of the detected WAP.

What Where Wi: An Analysis of Millions of Wi-Fi Access Points
TL;DR: An initial study that examines a database of over 5 million wireless access points collected through systematic wardriving by Skyhook Wireless found that the AP data, coupled with location information, can provide a fertile ground for understanding the "what, where and why" of Wi-Fi access points.
