Keysight Technologies Inc. announced that the company’s collaboration with CAICT (China Academy of Information and Communications Technology) has accelerated the 5G new radio (NR) base station performance test plan. The plan is endorsed by the IMT-2020 (5G) Promotional Group, the principal platform that brings together operators, vendors, universities and research institutes in China to promote 5G.
The collaboration has made it easy for base station manufacturers to validate with confidence the massive MIMO (massive multiple input multiple output) performance of their designs in accordance with the IMT-2020 test plan. Keysight’s PROPSIM F64 5G channel emulation solution, which emulates real-life radio conditions, supports the test plan to speed performance validation of new 5G mobile devices and base stations for deployment in China. Keysight’s PROPSIM F64 is a versatile channel emulation and modeling tool for verifying the end-to-end performance of 5G NR massive MIMO base stations and mobile devices using uncompromised and coherent complex 3D propagation channel models. MIMO significantly increases a network’s capacity and spectral efficiency while reducing wireless network interference to improve the end-user experience in 5G networks.
CAICT, a scientific research institute directly under the Ministry of Industry and Information Technology of China, is involved in defining 5G tests that form part of the IMT-2020 test plan. Massive MIMO technology uses antenna arrays with a large number of steerable ports to create reliable connections, which results in superior end-user performance. PROPSIM F64 supports up to 64 radio frequency (RF) ports to address these ultra-high fading capacity needs. Keysight’s 5G channel emulator creates a repeatable and reliable test method for validating end-to-end data throughput, beam handling, mobility and handover scenarios.
The collaboration between Keysight and CAICT resulted in the industry’s first verification of channel models that comply with both 3GPP 5G NR specifications and the IMT-2020 test plan using an end-to-end test set-up consisting of PROPSIM F64, a 5G base station (gNodeB) and a 5G mobile device.
Mobile operators around the world use PROPSIM F64 to validate 5G NR devices and base stations prior to hardware or software deployment in operational networks. PROPSIM F64 integrates seamlessly with Keysight's end-to-end network emulation portfolio to address the device workflow from R&D to design validation to manufacturing.
