As cellular network infrastructure expands to 5G technology, it will significantly affect various industries, such as telecommunication, aerospace, defense, and automotive, to name a few. Examples of applications include 5G cellular communication; aviation communication links; intelligence, surveillance, and reconnaissance (ISR) systems and processing; autonomous driving; smart city; and smart factory. Therefore, a highly reliable and resilient 5G network is crucial to our economic development and national security.
That said, testing of 5G system components faces new challenges compared to testing existing LTE/LTE-A (LTE and LTE-Advanced) communication system components. Firstly, 5G system components utilizing mmWave use higher-frequency bands than current LTE/LTE-A system components, which means 5G test system designs must overcome technical challenges associated with these bands.
