Location can be a lot of things: latitude and longitude, area, address, intersection, place… But it especially has a higher relevancy by being a context. There are two primary location technologies: IP location and triangulat
ion. IP location is widely available but it is only accurate to the city level. Concerning triangulation, GPS, which has the opposite characteristics of WiFi, doesn’t work indoors, but is accurate in rural areas. A cell tower, like 3G, works where there is cell coverage, in most areas, but is very inaccurate.
Using location improves the context for the user and can change your business. 2009 will be the year of location in the browser.
