Assistance for CICV in Full Vehicle MIMO-OTA Test and Research

Challenges

As automobiles are much larger than mobile phone devices, the investment for MIMO-OTA testing will be larger as well. Many questions need to be answered to control the size of the anechoic chamber and number of probes in it, to control the link budget to a reasonable level, and to control the investment to a reasonable scale. In addition, it has been proven that MPAC and RTS are almost equivalent in MIMO-OTA chipset testing, but both methods face respective challenges when migrated into full vehicle OTA testing. Theoretical analysis but short of complete testing data means only vendors with more experience and more investment are able to fulfill the tasks and play their roles in the development of standards and the creation of new solutions.
