Measurement of OTA performance ...
What is OTA performance? The TS8991 OTA performance test system measures the spatial radiation and sensitivity characteristic of wireless equipment. Network operators and also various standards prescribe these measurements as important quality parameters defining the behavior of a device in the wireless network. The test system sets up a connection to the EUT over the air interface and then measures both the radiated power and the limit sensitivity in different channels and wireless services (by means of the bit, frame, or packet error ratio) in all spatial directions. This yields the relevant parameters such as total radiated power (TRP) and total isotropic sensitivity (TIS), while the 3D radiation diagrams directly show the spatial distributions. Parameters and diagrams together conclusively describe the RF characteristic of the wireless application. Why use the TS8991? Owing to th……
