TRP/TIS stands for Total radiated power/Total isotropic sensitivity.
Knowing TRP and TIS requirements is fundamental to specifying antenna efficiency requirements.
TIS and TRP metrics have become increasingly important for carriers, as they can
quantify “over-the-air” performance with a single value.
Every carrier has its own set of TRP/TIS which they expect every device to qualify.
These numbers are captured during PTCRB testing and recorded in its report.
