5G handsets are mobile phones or wireless devices that can connect to 5G cellular networks, which provide faster speeds, lower latency, and increased network capacity compared to previous generations. The communication link between the handset and cellular network often encounters various challenges, such as signal propagation delay, Doppler shift, chip rate shift, path loss, and multipath fading, which can affect the transmission, decoding, reception, strength, synchronization, and fidelity of 5G signals. By simulating these impairments with the ACE9600, engineers can optimize 5G handset designs to deliver reliable connectivity and performance in diverse operating environments.
