total isotropic sensitivity (TIS)

Total IsotropicSensitivity (TIS) is a specification for isotropic sensitivity used in mobile radio technology. This parameter depends on the antenna and the receiver of

the communication link. As for the receiver sensitivity, it is the lowest receive level at which the receiver can maintain communication, for a given bit error rate

.When determining the TIS value, the input level is continuously increased until the given bit error rate is reached

.

This input level corresponds to the TIS value including the radio link

, i.e. antenna and receiving device. In the TIS measurement, the mean value of the sensitivity is determined in spherical space, i.e. with isotropic radiation. Another characteristic value used in mobile radio practiceis

the Total Radiated Power (TRP), which includes the transmitter and the passive transmission components of the antenna.
