Intelsat and SES agree on joint use of C-band by satellite and mobile operators

Intelsat and SES last week both agreed to back a proposal to the U.S. Federal Communications Commission (FCC) the seeks to protect satellite services in the 3700-4200 MHz C-band downlink spectrum while opening a specified portion of that spectrum for terrestrial mobile use.

The companies said their joint proposal sets a commercial and technical framework that would enable wireless operators to quickly access approximately 100 MHz of nationwide C-band downlink spectrum in the United States, speeding the deployment of next-generation 5G services. The idea builds on an innovative model first put forward to the FCC by Intelsat and Intel in October 2017 for spectrum sharing.

Under the proposal, a consortium of satellite operators would be created to oversee the governance of the initiative, define and implement the methodology for spectrum clearance, and serve as the sole interface for market-based transactions with parties interested in deploying terrestrial mobile services in specific portions of the C-band.

“The C-band is and remains a critical component of the U.S. network architecture. Space and ground segment operators have invested billions of dollars in U.S. C-band networks and connectivity and generate important value out of it. It is, therefore, our duty and mission to protect the C-band in the U.S. from any form of disruption and preserve its use,” stated Karim Michel Sabbagh, President and CEO of SES.

"Our proposed market-based solution provides a speedy resolution to the U.S. objective of accelerating deployment of 5G services. With Intelsat and SES now in agreement on major tenets of the framework and with the support of Intel, we are confident in our ability to implement this proposal quickly and efficiently, ultimately to the benefit of American consumers and the U.S. economy,” said Intelsat CEO Stephen Spengler.

Telefónica and Huawei test 5G-V2X Radio for uRLLC Assisted Driving

Telefónica and Huawei are running a Proof-of-Concept (PoC) testbed for 5G based vehicle communication networks (known as 5G-V2X) in their 5G Joint Innovation Lab at Madrid.

The 5G-V2X test is based on the latest 5G NR specs and includes advanced services such as vehicles platooning, extended sensors, advanced driving and remote driving, among others.

The so-called Ultra-Reliable and Low-Latency Communication (URLLC) mode for 5G NR offers the flexible design to support services with low latency and high-reliability requirements.

Huawei said the PoC demonstrates that URLLC can effectively support V2X with higher system capacity and better coverage. The exercise achieved 99.999% reliability with a low latency of 1ms required for autonomous driving in a typical macro cellular outdoor environment, such as dense urban, suburban and rural areas.  In the 5G-V2X PoC, a novel self-contained frame structure for radio transmission was used, both from the base station to the vehicle and from the vehicle to another vehicle. This allows much faster transmission feedback, enabling very low-latency communications. The great flexibility of the NR system framework allows the support of some advanced features, like Polar coding for small V2X packet error correction, an optimized HARQ (Hybrid Automatic Repeat Request) procedure for increased transmission reliability, or an ‘Inactive State’ for instantly sending short packets to control the car maneuver. To further enhance performance, another key technology, ‘SCMA-based (Sparse Coded Multiple Access) Grant Free Access, was tested.

Mr. Enrique Blanco, Telefónica Global CTIO, said: “This PoC between Telefónica and Huawei is another step towards 5G commercialization and a fully connected society. We will strengthen our collaboration by verifying 5G key technologies. Multiple novel use cases will be developed and provided to our customers.”

Dr. Wen Tong, Huawei Fellow and Huawei Wireless CTO, said: “We are pleased with our further collaboration with Telefónica in 5G technologies. The 5G-V2X PoC is another joint effort to pave the way for commercialization of 5G and lay a solid foundation to realize the 5G vision of enabling cooperative autonomous driving.”

Proposal to nationalize 5G draws immediate criticism from FCC, CTIA

National Security Council officials in the Trump administration are considering a federal role in building and operating a national 5G network, according to a report by Axios based on a leaked Powerpoint and memo. The idea is to develop a secure, nationwide 5G network at the federal level to stave off security concerns from China. The nationalized infrastructure would then be leased to mobile operators.

The report has drawn immediate criticism across the board.

FCC Chairman Ajit Pai: "“I oppose any proposal for the federal government to build and operate a nationwide 5G network.  The main lesson to draw from the wireless sector’s development over the past three decades—including American leadership in 4G—is that the market, not government, is best positioned to drive innovation and investment.  What government can and should do is to push spectrum into the commercial marketplace and set rules that encourage the private sector to develop and deploy next-generation infrastructure."

CTIA President and CEO Meredith Attwell Baker: “The wireless industry agrees that winning the race to 5G is a national priority. The government should pursue the free market policies that enabled the U.S. wireless industry to win the race to 4G.”

5G New Radio (NR) Specs Approved

The 3GPP initiative officially approved the 5G New Radio (NR) specifications. Balazs Berenyi, 3GPP RAN Chair, described the approval as "an impressive achievement in a remarkably short time, with credit due particularly to the Working Groups."

At Mobile World Congress 2017 in February, major mobile network operators and vendors issued a call to accelerate the 5G New Radio (NR) standardization schedule to enable large-scale trials and deployments a year earlier than the previously expected timeline. Companies backing this accelerated schedule for 5G include AT&T, NTT DOCOMO, SK Telecom, Vodafone, Ericsson, Qualcomm, British Telecom, Telstra, Korea Telecom, Intel, LG Uplus, KDDI, LG Electronics, Telia, Swisscom, TIM, Etisalat Group, Huawei, Sprint, Vivo, ZTE and Deutsche Telekom.

The first 3GPP 5G NR specification will be part of Release 15 - the global 5G standard that will make use of both sub-6 GHz and mmWave spectrum bands.

"We view both the Non-Standalone and Standalone modes of New Radio as equally important for the completeness of the 5G standard specification. This timely finalization of NSA is one important step on that journey and in the development of the 5G ecosystem," said Bruno Jacobfeuerborn, CTO Deutsche Telekom. "It is crucial that the industry now redoubles its focus on the Standalone mode to achieve progress towards a full 5G system, so we can bring key 5G innovations such as network slicing to our customers."

"The first version of 5G NR not only provides a NSA solution for 5G deployment but also completes the common part of NSA and SA, which lay a solid foundation for a global unified 5G system with global market scale. We believe the next important milestone that is SA standard providing end to end 5G new capability could be completed by June of 2018, which is very crucial to enable the operators to explore the enterprise and vertical markets. China Mobile is actively working with industry partners for 5G commercialization in year of 2020 and providing various services to customer." said Zhengmao Li, EVP of China Mobile Group.

Erik Ekudden, CTO at Ericsson, said: "3GPP has done a tremendous job to complete the first 5G specifications according to industry demand and expectations. As a prime contributor to 5G standardization, Ericsson has worked with industry partners in the evolution of mobile technology to a global network platform for consumers and enterprises. Our research team has worked on 5G since 2010 including early 5G testbed efforts created together with these industry partners. The open contribution-driven specification work and the rapid completion of the first 5G standards for global deployment demonstrates the strength of the 5G eco-system."



In October 2016, Verizon, Qualcomm Technologies, and Novatel Wireless, confirmed plans to expedite the rollout of 5G New Radio (NR) millimeter wave (mmWave) technology.  The companies have agreed to collaborate on over-the-air field trials based on the 5G NR Release-15 specifications being developed by 3GPP, with hopes of moving the mobile ecosystem towards faster validation and commercialization of 5G NR mmWave technologies at scale before the end of the decade.

The expedited plan call for an initial focus on 5G NR operation in 28 GHz and 39 GHz mmWave spectrum bands. The goal is to achieve robust multi-gigabit per second data rates with mobility at significantly lower latencies than today’s networks. Over-the-air trials are expected starting in 2018, that will be compliant with the first 3GPP 5G NR specification that will be part of Release 15. The trials will utilize 5G NR mmWave mobile test platforms from Qualcomm and will employ advanced 5G NR Multiple-Input Multiple-Output (MIMO) antenna technology with adaptive beamforming and beam tracking techniques.

In September, Deutsche Telekom activated its first, pre-standard 5G connection over its commercial network in central Berlin using 3.7 GHz spectrum.The 5G connection is operating a over 2 Gbps with a low latency of three milliseconds.

Huawei supplied the user equipment based on 3GPP specifications for 5G New Radio (NR), the deployment on commercial sites is the first in Europe and marks an important advancement in the global development of 5G.  

Vodafone initiates 5G trial with Ericsson

Vodafone UK is conducting a trial of pre-standard 5G using 3.5 GHz spectrum in central London.

The testing is carried out in partnership with Ericsson and King’s College London. The trial includes both indoor and outdoor configurations using MIMO, beamforming, beam tracking, and other advanced technologies.

Vodafone UK Head of Networks Kye Prigg said: “We’re delighted to be the first provider to test standalone 5G in the field, however, building a 5G network will take time. Right now, we’re also modernising our network by making smarter use of our existing mobile technology to keep ahead of consumption demands and provide the mobile coverage our customers deserve.

“5G also needs fibre optic cables. Together with CityFibre, we will soon start work installing the advanced fibre networks providing high-capacity backhaul connections required for 5G mobile services.”
