Ericsson Achieves 315 Mbps 5G Wireless Upstream Link
Ericsson says that it has achieved 5G single user multiple input multiple output (SU-MIMO) uplink speed of 315 Mbps, which it claims is 15 to 20 times faster than typical current speeds.
The context Ericsson provides is that uplink capacity always has been a bottleneck, That challenge is growing and will be will be a key to the success of 5G. Ericsson suggests that the focus to date has been on supporting download-intensive use cases such as video streaming, augmented reality and virtual reality.
Just as is the case with wireline broadband, upstream capability for mobile is taking on added importance. Subscribers are increasingly uploading high resolution images and video using 4K- and 8K-capable devices.
Ericsson reached near theoretical peak uplink single user throughput using SU-MIMO technology and uplink (UL) 256 Quadrature Amplitude Modulation (QAM) in New Radio (NR) standalone (SA) mode.
The demonstration was conducted at Ericsson’s North America headquarters in Plano, Texas. It used the company’s 5G Distributed Innovation Network and various Time Division Duplex (TDD) patterns.
The 315 Mbps data rate was reached under a test license of 100 MHz — from 3700 MHz to 3800 MHz — and a mobile test device powered by the Qualcomm Snapdragon X60 5G Modem-RF System. The live C-Band network for the demo also featured a commercial 64T64R advanced antenna system (AAS) radio on the building rooftop and the support of 5G core software.
“This network serves as a great test-bed for demonstrating new applications and the monetization of 5G, particularly in an enterprise environment where edge computing, network slicing and orchestration are critical,” Arvinder Anand, Vice President of Architecture, Technology & E2E Solutions Digital Services for Ericsson North America, said in a press release.
