märgistusseadmeid

Märgistusseadmed are a type of electronic device used in Estonia and other Baltic countries to identify and track mobile phones and other devices. The devices emit a code that is used to determine the location and identity of the emitting device, and can be used for various purposes such as tracking lost or stolen phones, and preventing the use of prepaid mobile phones for criminal purposes.

Märgistusseadmed work by emitting a radio frequency signal that contains a unique identifier code, which is then received by a network of antennas that cover the country. The received signal is then used to triangulate the location of the device using a technique called trilateration. This method involves measuring the time difference between the signal and its reception at multiple antennas, and using this data to calculate the device's location.

The use of märgistusseadmed has been contentious in Estonia, with some arguing that the devices infringe on citizens' right to privacy. In 2010, the Estonian government decided to cancel plans to implement a more widespread network of märgistusseadmed due to concerns over the potential for misuse of the technology. However, some märgistusseadmed continue to be used in limited areas for specific purposes, such as in schools and other institutions. Despite the controversy surrounding their use, märgistusseadmed remain a widely recognized and utilized technology in Estonia and other countries.
