Keysight Technologies has announced that NEC Europe has selected Keysight to create an advanced RF propagation environment for verifying the performance of Open RAN base stations equipped with massive MIMO technology.
Prior to deployment, network equipment manufacturers and mobile operators need to verify that open RAN (O-RAN) equipment with complex antenna configurations effectively manage signal fading caused by buildings and terrain. An increasing number of RANs use massive MIMO (mMIMO) and beamforming technology to support high data rate applications. Greater RAN complexity intensifies the need for assessing how well a base station's RF transceiver performs under multi-path propagation signal conditions, produced by fading.
"Keysight's mMIMO base station fading performance toolset enables us to rapidly emulate real world radio conditions in a controlled and repeatable way in NEC's Interoperability Test and Validation environments," said Jon Van-Orden, head of Engineering for the NEC 5G Centre of Excellence. "As a result, we're able to verify the interoperability of NEC's Open RAN mMIMO radios with other equipment with O-RAN standard interfaces.”
Advanced RF fading performance and interoperability testing under real-world conditions helps network equipment manufacturers and mobile operators achieve quality of service goals. Keysight has launched three new base station test systems for verifying RF fading performance of O-RAN infrastructure equipped with complex antenna configurations. The new toolsets provide users with access to test case packages covering relevant specifications defined by 3GPP, thereby accelerating MIMO, mMIMO, mmWave and beamforming performance verification of new designs.
Keysight's new automated toolsets support 3D fading and mobility scenarios for advanced 5G base station testing, verification and optimization. The toolsets leverage Keysight's PROPSIM Channel Emulation Solutions, which cover all 3GPP-specified 5G NR frequency bands and bandwidths across sub-7GHz (frequency range 1) and mmWave spectrum.
