1. Introduction to OTA testing

OTA is the abbreviation of Over the Air in English, literally translated as "through the air". In the field of mobile communications, it can generally be understood as evaluating the "air interface" performance of a DUT (Device Under Test, device under test). The air interface performance here mainly refers to the two most important indicators including TRP (Total Radiated Power, total radiated power) of the evaluation transmitter and C-TIS (Combined Total Isotropic Sensitivity, composite total omnidirectional receiving sensitivity) of the evaluation receiver. is dBm.

 

2. Introduction of OTA laboratory

The OTA laboratory of the affiliated company of GCDC Group is built in accordance with the OTA specification requirements of CTIA in North America. It can provide a corresponding test environment for active or passive antennas. It can electronically scan the radiation performance of the antenna, and then collect it through the computer. Analyzing and organizing to confirm the performance of the antenna has the advantages of high repeatability, high accuracy, and high resolution.
