Improving 5G Millimeter-Wave Signal Analysis Accuracy
Millimeter-wave technology is a crucial element that sets 5G apart from 4G Long Term Evolution (LTE). The technology creates many challenges across the workflow in design, manufacturing, and deployment. At mmWave frequencies, significant path loss makes radio-frequency (RF) power limited and costly. And mmWave frequencies introduce a disruptive change in test methods. Measuring performance metrics using over-the-air (OTA) test methods makes achieving accurate and repeatable results more difficult. Wide bandwidths also introduce more noise and frequency responses. These challenges increase measurement complexity and uncertainty for chipset and device makers, network equipment manufacturers, and operators.
