Abstract
This paper describes a new model for delivering hyper-local data to mobile subscribers. Our model uses any exiting or especially created Wi-Fi hot spot as presence sensor that can open access for some user-generated content. In our approach we can describe hyper local data as info snippets that are valid (relevant) for mobile subscribers being at this moment nearby some Wi-Fi access point. And an appropriate mobile service (customized browser) can discover that information to mobile users. Service builds on the fly dynamic web pages and lets mobile subscribers to browse hyper-local data only. As the possible use-cases we can mention for example delivering news and deals in malls, news feeds for office centers and campuses, Smart City projects, personal classifieds etc.

Summary
Per Wikipedia, context awareness is defined complementary to location awareness. Whereas location may serve as a determinant for resident processes, context may be applied more flexibly with mobile computing with any moving entities, especially with bearers of smart communicators. There are many different approaches for getting location info for mobile subscribes In general it could be pretty standard nowadays (GPS, cell-id, assisted GPS [10]), but everything is getting more complicated as soon as we need indoor positioning. The cited article shows show that commodity 802.11 equipment is surprisingly vulnerable to certain patterns of weak or narrow-band interference This enables to disrupt a link with an interfering signal whose power is 1000 times weaker than the victim's 802.11 signals, or to shut down multiple access points, multiple channel managed network at a location with a single radio interferer. This can take place with any distance estimation method available (e.g., using signal strength) They can refine their estimations iteratively as they incorporate new positioning information. Why do not request data directly if we can estimate location?
