Navigation services allow locating the exact geographical position of a mobile device using one of available positioning systems and get direction and/or navigate user to required location including vehicles, crafts, and pedestrians. This service is often linked with ‘Information Services’ described above (e.g. get direction to point of interest). However, according to LBS definition only those navigation products that are receiving the information from wireless networks can be considered a part of Location Based Services. The LBS approach to navigation gives particular advantage over mobile navigation software using data stored on the memory of a mobile device, because it potentially gives user the access to the real-time data. The limitation of large volumes of data needed to be transferred over wireless network is decreasing as many network operators offers unlimited or reasonably priced data transfer
