What are the three main components used for cell phone communications?
What will be an ideal response?
ANSWER: As described in NIST SP 800-101, three main components are used for communication with these cells:
* Base transceiver station (BTS)—This component is made up of radio transceiver equipment that defines cells and communicates with mobile phones; it’s sometimes referred to as a cell phone tower, although the tower is only one part of the BTS equipment.
* Base station controller (BSC)—This combination of hardware and software manages BTSs and assigns channels by connecting to the mobile switching center.
* Mobile switching center (MSC)—This component connects calls by routing digital packets for the network and relies on a database to support subscribers. This central database contains account data, location data, and other key information needed during an investigation. If you have to retrieve information from a carrier’s central database, you usually need a warrant or subpoena.
