T-Mobile hits 5.6 Gbps with Ericsson's 16-layer MU-MIMO

 T-Mobile achieved peak cell throughput of more than 5.6 Gbps on one channel of 2.5 GHz spectrum in a demonstration of 16-layer multi-user multi-input multi-output (MU-MIMO) technology.The demonstration achieved more than 700 Mbps on each device in the cell. 

The demonstration used Ericsson's commercially available massive MIMO radio with 64 antennas from Ericsson and OnePlus 8 5G smartphones. Sixteen unique streams of data were transmitted — each stream capable of hitting more than 350 Mbps.  With two data streams for each device, a total of 700+ Mbps for each smartphone was achieved.

T-Mobile said it expects to begin deploying the technology this year. 

“This is what you get when you pair T-Mobile’s unmatched spectrum portfolio with the best damn team in wireless — innovation that changes the game for the entire industry,” said Neville Ray, President of Technology at T-Mobile. “We have a 5G network that’s second to none, and it’s getting better by the day thanks to our amazing engineers and partners. Just wait until you see what they do next for our customers!”

In tech terms, with 100 MHz of total 5G spectrum in the demonstration, T-Mobile was able to achieve an 50+ bps/Hz in spectral efficiency.

FCC chairman pitches 3.45-3.55 GHz band for 5G

Federal Communications Commission Chairman Ajit Pai has circulated a petition to his fellow commissioners to make the 3.45-3.55 GHz band available for commercial use throughout the contiguous United States. 

“We are moving forward quickly, in coordination with the Executive Branch, to ensure that this mid-band spectrum is available for commercial 5G deployment.  This is another major step forward in advancing American leadership in 5G and producing benefits for America’s wireless consumers,” said Chairman Pai.  “Our 5G FAST Plan is in full swing.  With this 3.45 GHz band proposal, the upcoming C-band auction of 280 megahertz of spectrum, and the recently completed auction for Priority Access Licenses in the 3.5 GHz band, the Commission is on track to make a wide swath of 530 megahertz of continuous mid-band spectrum available for 5G.  Combined with our work to make low- and high-band spectrum available for flexible use as well as our successful efforts to expedite the deployment of wireless infrastructure and fiber, we are establishing a strong foundation for wireless innovation and investment.  I hope my colleagues will join me in supporting this important item at our monthly meeting.”

Credo intros DSP for 5G front- and mid-haul

Credo introduced a DSP for optical modules used in 5G front- and mid-haul wireless networks. 

The Credo Seagull 50, CFD10101, is a versatile full-duplex product that can be used in next-generation QSFP28, DSFP, and SFP56 pluggable optical transceivers. It supports 50Gbps SR/DR/FR/LR and ER applications based on PAM4 modulation. 

Seagull 50 operates over the full industrial temperature range of -40oC to +85oC module case and is ideal for use in datacenters and 5G wireless/eCPRI front-, mid- and backhaul applications.

The DSP can be used as a gearbox or retimer. In gearbox mode, the IC is configured as two lanes of 24.33-25.78Gbps NRZ on the host side to one lane of 50.135-53.125Gbps PAM4 on the line side. In retimer mode, the DSP is configured as one lane of 50.135-53.125Gbps PAM4 to one lane of 50.135-53.125Gbps PAM4.

Broadband Forum advances its technical work program

The Broadband Forum added Mike Talbert, of Verizon, and Ding Hai, of China Unicom, to its board of directors. Their appointments follow the retirement of Broadband Forum President Tom Starr, of AT&T, who has held a Board position for 26 years. He is succeeded by Bernd Hesse, of Calix.

The Broadband Forum announced the following advancements in its technical work following its recent virtual Q3 meeting:

• The Broadband User Services Work Area is working alongside the prpl Foundation to explore how using USP can create interoperable smart gateways that provide application developers with an easy way to build new services to operate on the gateway. 
• The Open Broadband – Broadband Access Abstraction (OB-BAA) project team finalized its fourth major release of its reference implementation of the CloudCO's BAA layer which enables vendors to provide support for white box implementations for various types of access nodes using either standard adapters or via vendor specific adapters, while the OB-USP-Agent Work Area’s Canary Release is nearing completion. This release focuses on providing support for MQTT and Architecture improvements to better support OpenWRT/prplWRT and RDK-based implementations. 
• The Physical Layer Transmission Work Area published its Test Plan related to Reverse Power Feed (TR-338), which specifies a set of test cases and related pass or fail requirements for reverse powering of remote network nodes from customer premises equipment.
• The Q3 meeting – which took place from Monday, August 31 to Friday, September 4 – also saw Broadband Forum confirm the next dates of its vBASe series. It will host its first-ever virtual demo at Broadband World Forum, from October 13-15, showcasing the latest developments of its OB-BAA open source project. A panelist session on the Connected Home, along with a live Q&A, will also be held.
• vBASe North America will then take place on October 26, with a theme of “2020 Lessons, 2021 Reality”, while vBASe Australia will see Broadband Forum team up with nbn to provide three weekly 90 minute sessions to deliver a market update.

“Broadband Forum has always worked closely with operators across the globe, as they provide us with unique insight into what is important for the industry and ensure that our work remains at the cutting-edge,” said Broadband Forum Chairman John Blackford. “These latest board appointments build upon that collaboration as we come to the beginning of an incredibly exciting period for Broadband Forum. We are continuing to make great strides in 5G convergence, our User Services Platform (USP) efforts are continuing to gain momentum, and we have a new open source project launching that could be a true game changer for gigabit broadband.”
