KEYSIGHT TECHNOLOGIES 5G channel sounding Reference Solution accelerates advanced research of millimeter-wave 5G channel models and includes ultra-broadband and MIMO, key requirements to measure the millimeter-wave channel and validate new air interface standards. Among the mobile broadband requirements of 5G are new technologies yielding over-the-air data rates of as much as 10Gbps. To achieve these requirements, new air-interfaces are being developed to operate in frequency bands from 10-100GHz. Product combines metrology grade hardware, software and expertise to allow customers to quickly characterize the channel behavior in these frequency bands and enable researchers to develop the necessary channel models for designing and validating air-interface alternatives. Researchers can get very accurate absolute delay measurements with system-wide calibrations, precise timing, and synchronization. They will also save time and disk space by using the multi-channel, real-time data processing, and correlation of the channel impulse response data (CIR).
