As Foursquare has been released, Location-Based Services (LBS) are more and more popular even best Chinese Android phone get that function in it. More and more smartphone apps integrated Location-Based function into. Before smarphones get popular, GPS is the closest concept to LBS. At the PC age, it’s not necessary to get our position, only GPS in the car is useful in our life. But now, we use mobile devices like smartphone and tablet everywhere, locations are very important information to us. For example, you tweet what you are eating and who you are with when you traveling, the app add the location automatically so your friends can see where you are. Social networking is the main theme of this age pillared by Twitter and Facebook.

How do the LBS work?

Apps can track your position, have you ever worried about your privacy? The GPS is controlled by yourself and you may wonder why you phone and get your location. This is how it works. Your phone estimates its location using a variety of signals. GPS is the most accurate, determining your phone’s position to within about five meters. But if you are underground, in a building, tunnel or downtown area surrounded by tall structures, GPS signals are weak or blocked. Under these circumstances, your phone relies on signals do not broadcast their own locations, Apple, Google and other smartphone companies have gathered databases marking the locations of these sources. If your phone is in the range of three cell towers, it determines the distance to each one, creating a “triangulation” or intersection point locating you to within about 500 meters. In most cases, that accuracy is enough for the time when you traveling.

How to take the advantages of LBS?

Most usual use of LBS is maps. You use Google Maps to find where you are and where you are going, this app will show the route. As you travel the recommended route, the phone automatically update your position on the map so you can mark your progress as you go. The map shows nearby restaurant, gas stations, banks, and lodging. I think watch cell phone fits LBS perfectly in the size, and I even think watch cell phones have only LBS is enough. In the realm of social media, well-known social media sites, including Facebook, Foursquare and Google Plus, combine social contacts with clubs, restaurants and public venues. You “check in” to a location, invite others and earn participation points, in some cases, from the app’s operator.

LBS drain the battery of your smartphone fastly because your phone monitors a steady stream of signals and that keep the CPU busy. If you only use LBS occasionally and the smartphone is not good as GT-i9300 cell phone, turn off the LBS.
