Near LBS (NLBS) involves local-range technologies such as [[Bluetooth Low Energy]], [[wireless LAN]], infrared or [[near-field communication]] technologies, which are used to match devices to nearby services. This application allows a person to access information based on their surroundings; especially suitable for using inside closed premises, restricted or regional area.
Another alternative is an operator- and satellite-independent location service based on access into the deep level telecoms network ([[Signalling System No. 7|SS7]]). This solution enables accurate and quick determination of geographical coordinates of mobile phones by providing operator-independent location data and works also for handsets that do not have satellite navigation capability.

In addition, the [[IP address]] could provide the end-user's location.

Many other [[local positioning systems]] and [[indoor positioning system]]s are available, especially for indoor use. GPS and GSM do not work very well indoors, so other techniques are used, including co-pilot beacon for CDMA networks, Bluetooth, UWB, [[RFID]] and Wi-Fi.<ref>[http://www.icsi.berkeley.edu/pubs/speech/preciseindoor10.pdf "Precise Indoor Localization Using Smart Phones"] {{Webarchive|url=https://web.archive.org/web/20130513155817/http://www.icsi.berkeley.edu/pubs/speech/preciseindoor10.pdf |date=2013-05-13 }} E.
