Total Radiated Power (TRP) and Total Isotropic Sensitivity (TIS) goes under the category of Bluetest's active measurements. Active measurements means that the transmitter/receiver in the DUT is active and powered up. Active measurements will give you a complete overview of how the whole system in your device is performing. These are parameters directly related to the antenna radiation efficiency,
The current trend in active device over-the-air (OTA) testing is to characterize the system performance via data throughput. With Bluetest measurement software the throughput can be measured at either IP or MAC layer in a fast, repeatable, and convenient way.
