Services based on instant location of customers are extremely useful for advertising offers or communicating different types of information to the customers’ mobile devices.

Refining by location allows close targeting, which, in turn, increases the probability for consumption of the offered goods and services as well as an increase in consumer loyalty.

The location of mobile devices can be realized through the use of embedded GPS modules (for several device models) or through the built cellular by the mobile operators. In both cases, the accuracy of localization is quite high, allowing a relatively precise location of the user.
