Mobile positioning may include location-based services that disclose the actual coordinates of a mobile phone, which is a technology used by telecommunication companies to approximate the location of a mobile phone, and thereby also its user.The technology of locating is based on measuring power levels and antenna patterns and uses the concept that a powered mobile phone always communicates wirelessly with one of the closest base stations, so knowledge of the location of the base station implies the cell phone is nearby.With the recent advances in mobile communication, it has become important for people to monitor the activities of someone else’s mobile phone in certain situations.As a result of this growing demand, a number of companies have come up with their mobile spying programs.To locate a mobile phone using multilateration of radio signals, it must emit at least the roaming signal to contact the next nearby antenna tower, but the process does not require an active call.The Global System for Mobile Communications (GSM) is based on the phone's signal strength to nearby antenna masts.Most modern mobile telephone services use a cellular network architecture, and, therefore, mobile telephones are often also called cellular telephones or cell phones.
The first handheld mobile phone was demonstrated by John F.
A mobile phone is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area.
The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN).
Qualified services may achieve a precision of down to 50 meters in urban areas where mobile traffic and density of antenna towers (base stations) is sufficiently high.
Rural and desolate areas may see miles between base stations and therefore determine locations less precisely.
