According to the data provided by the International Measurement Agency (BIPM) based on the data provided by more than 100 atomic clocks in more than 20 countries in the world, the "International Time Standard" was called the International Atom (TAI). tai is the International Atom Time (TAI). The frequency of atomic energy level transitions for certain elements has extremely high stability. It can be used as a time label based on the energy -level transition atoms based on the 铯 atom (CS 132.9). The relevant information: 铯 133 Atomic base state two ultra -fine energy levels to transition the radiation cycle under zero -magnetic field 9,192,631,770 times the time. 1967 The Trusteen -Thirteenth National Integrated Commission decided to set the above -mentioned atoms that realized the above atoms on the sea level as the time unit of international units. Since then, the time measurement standard has officially transitioned from the macro field of astronomy to the micro -field of physics.
TAI is the tracking area code of the LTE network. is composed of MCC, MNC, and TAC. Generally, MCC and MNC will not change. The TAC is planned according to needs.
