Detailed explanation-1: -A base station, also called Base Transceiver Station, abbreviated as BTS, is the most visible network element of a GSM system. Compared to fixed-line networks, the base stations replace the wired connection to the subscriber with a wireless connection, which is also referred to as the air interface.
Detailed explanation-2: -Most SIM cards use a four digit PIN. Others can use five or six digits. To override a lost, forgotten, or improperly entered user PIN, manufacturers also have a personal unlocking key (PUK). This is also referred to as personal unblocking key.
Detailed explanation-3: -The base transceiver station (BTS) is connected via landline to a radio network controller (RNC). The RNC manages several base transceiver stations. The radio network controller is connected to a Mobile Switching Center. Each Mobile Switching Center (MSC) manages the cell towers in a single coverage area.
