Swedish telecommunications equipment vendor Ericsson has shown off its ability to build high-capacity low-latency 5G networks by demonstrating the first live C Band network with throughput of 5.4Gbps at its North American headquarters in Texas.

The company said it had used 16-layer Multi-User MIMO 256 QAM with 6UEs over 100MHz to achieve this result in what was the first such trial in the US.

Kevin Zvokel, head of Networks at Ericsson North America, said: “Exceeding 5Gbps on C Band spectrum sets high expectations for mid-band 5G deployments in the US.

"Ericsson is prepared to help our customers deploy 5G infrastructure now with superior performance and coverage to deliver the full potential of 5G.”

The network at Ericsson's Texas campus uses a test licence C Band Special Temporary Authorisation (STA) from the US Federal Communications Commission and consists of 64T64R AAS radio, baseband, Router 6000 and core network equipment. It is part of the 5G Distributed Innovation Network at the Texas facility.

The company said C Band comprised the mid-band spectrum, made up of 500Mhz between 3.7 and 4.2 GHz, that was very important in 5G deployment, especially in the US.

Mid-band spectrum blends extended coverage with increased capacity and will help 5G use cases, like connected factories, smart cities, and virtual reality gaming.

It is used by most countries and an upcoming C Band auction for 280MHz at the end of the year is awaited.

The test setup was tested by field research and consulting services Signals Research Group whose president. Michael Thelander, said: “The throughput demonstrated by the Ericsson demo network establishes a new benchmark for network performance and showcases the benefits that will be available to the market when mid-band networks are available.

"5G in mid-band networks in the US will be a fantastic boon to enterprise and consumers. It is crucial that US operators have access to reliable radio technology to deploy these networks.”

Active Vs. Passive DWDM Solutions

An active approach to your growing optical transport network & connectivity needs.

Building dark fibre network infrastructure using WDM technology used to be considered a complex challenge that only carriers have the means to implement.

This has led many enterprises to build passive networks, which are inferior in quality and ultimately limit their future growth.

Why are passive solutions considered inferior? And what makes active solutions great?

Read more about these two solutions, and how PacketLight fits into all this.


WEBINAR INVITE 8th & 10th September: 5G Performing At The Edge

Don't miss the only 5G and edge performance-focused event in the industry!

Edge computing will play a critical part within digital transformation initiatives across every industry sector. It promises operational speed and efficiency, improved customer service, and reduced operational costs.

This coupled with the new capabilities 5G brings opens up huge opportunities for both network operators and enterprise organisations.

But these technologies will only reach their full potential with assured delivery and performance – with a trust model in place.

With this in mind, we are pleased to announce a two-part digital event, sponsored by Accedian, on the 8th & 10th of September titled 5G: Performing at the Edge.
