But GPS enabled devices are not the only devices of this type. You can tap the location with something more or in other words you can always tap in to a location based service even without a GPS enabled device.

GPS although is much more accurate in tapping a particular location but it is almost impossible to obtain same results when you are surrounded by sky scrappers or inside the basements. Such type of “Urban Canyons” or the ‘dark-zones’ make the GPS device unable to catch signals and the device becomes almost inoperable.

“Network Based Triangulation Methods” and “Handset Based Triangulation Methods” or among the other methods that can perform almost the same function as a typical GPS device will do. The first one is though more accurate and better.

The triangulation methods involve three or more of the nearest cell towers that do the measuring of handset’s signal power and perform calculations for a particular position. This is based on location and orientation of antennas.

“Handset-Based Triangulation” makes it necessary for a typical handset to scan its surroundings. The handset will automatically spot out three nearest towers. Apart from the database that is locally stored, other information’s will be transmitted through cellular or Wi-Fi link to a server. Here all the calculations and measurements will also be completed and the coordinates will be provided to the user’s end defining the exact location.

Google’s” My Location” is such applicability. The company has recently announced that ‘Google maps’ will also use the cellular “Navozone”; another service provider is also providing almost accurate location results with the help of “Wi-Fi Hotspots”. This method is comparatively more appropriate for ‘Wi-Fi-Networks.

Dealing with several concerns including the privacy aspects, many service providers are looking forward to technological advancements that would be more facilitating for the common persons for using location based services. Anonymity of information is one of such concerns that some companies are addressing currently. Experts are viewing a more conducive environment for development of employee oriented devices.
