Over The Air Testing (OTA)

02/07/24

OTA testing is key for product development, and in the case of 5G products that utilize millimeter wave (mmW) frequencies, there is an increased reliance on this testing.

In wireless systems, there are two methods of determining the wireless function’s performance: either testing over-the-air (OTA) or conducting measurements that utilize cables to interface with the product directly, bypassing the antenna. This paper highlights OTA testing issues and what designers need to know when developing 5G products.

This paper explores:

Challenges with power measurements and path loss at higher frequency wavelengths
Testing the antenna perceived radiation pattern and radio performance for user equipment
Testing setups for MIMO antennas
OTA's impact on thermal vacuum testing for space flight applications
