Roy Olmstead

Telephone wiretapping began in the 1890s, following the invention of the telephone recorder, and its constitutionality was established in the Prohibition-Era conviction of bootlegger Roy Olmstead.

Timing advance

technical limitations
It is also possible to get greater resolution of a phone's location by combining information from a number of cells surrounding the location, which cells routinely communicate (to agree on the next handoff—for a moving phone) and measuring the timing advance, a correction for the speed of light in the GSM standard.
Timing Advance is significant for privacy and communications security, as its combination with other variables can allow GSM localization to find the device's position and track the mobile phone user.
