Keysight is first past the post with end-to-end 5G NR-ready channel emulation

Keysight Technologies announces that it is able to offer performance validation of chipsets, devices, and base stations across all 5G new radio signal bandwidths and carrier aggregation schemes.

It believes that the PROPSIM F64 is the industry’s first 5G New Radio (NR)-ready channel emulation solution. Keysight’s PROPSIM F64 5G channel emulation solution enables chipset, device, and network equipment manufacturers to characterise end-to-end system performance of the latest 4G and 5G basestations and mobile devices by emulating real-world radio conditions in the lab.

5G NR deployments require advanced technologies to achieve higher data rates of up to 20Gbit per second. The use of wider signal bandwidths, mmWave frequencies, and Massive MIMO with hybrid beamforming, enables these higher data rates through the more effective use of the wireless propagation channel. As a result, designers need to validate the end-to-end performance of multi-mode devices and basestations under real-world complex 3D fading and interference channel conditions. In response, Keysight’s PROPSIM F64 5G channel emulation solution supports all 5G NR signal bandwidths, carrier aggregation (CA) schemes, and offers the highest number of channels for massive MIMO channel emulation and testing, says the company. It integrates channel modelling tools for user-defined 3D spatial scenarios and dynamic modelling of movement. It supports both conducted and over-the-air (OTA) testing across sub 6.0GHz and mmWave frequencies.

The PROPSIM F64 5G integrates seamlessly with Keysight’s end-to-end network emulation portfolio to address the entire device workflow from R&D to design validation, to manufacturing. Users can validate protocol layers and radio frequency (RF) performance of a 5G NR device and also gain access to key performance indicators for beam management, data throughput and stability under 5G fading channel conditions.

In December 2017, Keysight introduced the first 5G NR-ready network emulation solution. It allows the entire mobile ecosystem to access a common scripting engine that uses interactive 5G stack and tools, to resolve the issue of disconnected workflows between teams, to promote cost-efficient testing.
