гЂђWebinarгЂ‘Achieving High Defect Coverage for Safety Critical and High Reliability DesignsДЄs signal strength decreases, noise from the test system being used to measure it will also reduce the SNR, impacting results. Finally, mmWave uses higher-order modulation schemes to improve spectral efficiency, which in turn requires improvements in error vector magnitude (EVM) performance. The wide bandwidth of mmWave-which is such an attractive feature for 5G communications-also degrades the signal-to-noise (SNR) because the energy from the signal spreads across the bandwidth. Accurately measuring the performance of mmWave devices with over-the-air (OTA) test equipment and methodologies is also difficult. For starters, mmWave does not propagate very far-mmWave transmissions are easily absorbed by the atmosphere and do not penetrate trees, building walls, and other infrastructure. However, mmWaveвЂ™s advantages for 5G communications are partially offset by several technical challenges. mmWave transmissions are smaller than other wireless communications signals, making them ideal for high-speed transmissions in dense urban areas, where many devices operate in close proximity.

MmWave spectrum is attractive for use in wireless communications because these bands are relatively under-utilized, meaning there is plenty of available bandwidth. Most of the gain comes from the utilization of 5G Frequency Range 2 (FR2) found in millimeter-wave (mmWave) spectrum. Understanding and utilizing various RF signal path options on your signal analyzer can help you overcome challenges when making 5G mmWave measurements.ДҐG promises dramatic improvements over previous generations of wireless communications technology, particularly in speed, latency, bandwidth, and quality.
