FCC advances C-V2X in 5.9 GHz proposal

The FCC is proposing rule changes for the 5.9 GHz (5.850-5.925 GHz) band, which has been reserved for use by Dedicated Short-Range Communications (DSRC), a radio service designed to enable vehicle-related communications.  However, after 20 years, DSRC still has not been widely deployed, and this spectrum therefore generally remains unused.

The FCC is proposing to designate the lower 45 megahertz of the band for unlicensed uses like Wi-Fi.  This 45 megahertz sub-band can be combined with existing unlicensed spectrum to provide cutting-edge high-throughput broadband applications on channels up to 160 megahertz wide. 

The FCC is proposing to dedicate the remaining 30 megahertz of the band for use by transportation and vehicle safety-related communication services.  Specifically, in the NPRM, the Commission proposes to revise its rules to provide Cellular Vehicle to Everything (C-V2X), an emerging standard for transportation applications, with exclusive access to the upper 20 megahertz of the band.  Under the Commission’s current rules, no spectrum is allocated for C-V2X.  The NPRM seeks comment on whether to retain the remaining 10 megahertz for use by DSRC systems or to dedicate it for C-V2X use. 

"One promising new technology that is gaining momentum in the automotive industry is Cellular Vehicle to Everything, or C-V2X.  C-V2X would use standard cellular protocols to provide direct communications between vehicles, and, as the name suggests, everything—including other vehicles on the road, infrastructure (like light poles), cyclists (like me), pedestrians, and road workers.  C-V2X also is expected to support new, advanced applications as we transition to faster, more responsive 5G networks.  And it’s backed by automakers like Ford, Audi, BMW, Daimler, and Tesla.  So we’re proposing to designate the upper 20 MHz for this exciting, new automotive communications technology," states Ajit Pai, FCC Chairman.

FCC looks to open 3.1-3.55 GHz band for 5G

The FCC is considering opening the 3.1-3.55 GHz band for advanced commercial services, including 5G. Specifically, the FCC is proposing to remove and relocate the non-federal users in the 3.3-3.55 GHz portion of the band, which currently is allocated for non-federal secondary radiolocation services and amateur use.  The item also seeks comment on the relocation options and transition mechanisms for these incumbent non-federal users to the 3.1-3.3 GHz band or to other frequencies.

FCC Chairman Ajit Pai states: "Our action today is just another example of our comprehensive strategy to free up spectrum for commercial use across the country and advance American leadership in the next generation of wireless connectivity.  We have been aggressive in freeing up mid-band spectrum in particular.  For instance, an auction of the 3.5 GHz band will commence on June 25, 2020.  The Commission is also focused on commencing an auction of 280 MHz of spectrum in the C-band late next year.  And we recently voted to put the 2.5 GHz band—the largest swath of contiguous spectrum in the country below 3 GHz—to use for the American people.

In addition to these mid-band efforts, we’ve also been hard at work when it comes to high-band spectrum.  In January, we finished an auction of spectrum in the 28 GHz band.  In May, we concluded an auction of spectrum in the 24 GHz band.  And earlier this week, we launched an auction of 3,400 MHz of spectrum in the upper 37, 39, and 47 GHz bands, which is the largest spectrum auction in American history."

Cisco presents Silicon One engine of "Internet for the Future"

Cisco unveiled its next generation architecture - its foundation for building a new Internet, by combining silicon, optics, and software. At its "Internet for the Future" event in San Francisco, the company also unveiled new carrier-class routers and discussed an expanded sales strategy that will allow hyperscale web companies and other customers to purchase silicon and optical components directly.

Cisco Silicon One is the new unified, programmable silicon architecture that will be the foundation of Cisco’s routing portfolio going forward, including fixed and modular platforms.  It offers programmability, buffering, power efficiency, scale, and feature flexibility.


The first Cisco Silicon One device - dubbed Q100 - surpasses the 10 Tbps routing performance, although in the near term the company expects to deliver up to 25 Tbps. Q100 actually began sampling 2 years ago and is now shipping. It offers global route scale, deep buffering, and P4 programmability with switching efficiency. It delivers 2x bandwidth and 3x packets-per-second over current routing silicon.

The new Cisco 8000 series carrier-class router is the first platform built with Cisco Silicon One, specifically the Q100. Key features include:
  • Optimized for 400 Gbps and beyond, starting at 10.8 Tbps in just a single rack unit
  • Powered by the new, cloud-enhanced Cisco IOS XR7 networking operating system software,
  • designed to simplify operations and lower operational costs
  • Offers enhanced cybersecurity with integrated trust technology for real-time insights into the trustworthiness of critical infrastructure
  • Service providers gain more bandwidth scale and programmability to deliver Tbps capacity
Saudi Arabia's STC will be the first carrier to deploy the Cisco 8000 series. Comcast and NTT Communications are also testing the platform.

The new Cisco IOS XRT promises:
  • 50% less memory footprint
  • 50% faster boot time
  • 40% smaller image sizes
  • 40% faster download
  • Root-of-trust in the hardware and a cloud-based method for verifying trust in the NOS
Silicon + Optics

Over the past few years, Cisco has been investing in silicon photonics, including its acquisitions of CoreOptics, LightWire and Luxtera.  Its acquisition of Acacia is pending -- all of which reflect the company's desire to improve the availability, capacity, density and power-efficiency, especially at 400G and above.  The strategy has 3 major themes:

  • Optical  innovations will drive architectural transitions, including coherent pluggables and co-packaging.
  • Different optical consumption model, including fully integrated systems, pluggables, and components
  • Cisco Optics on non-Cisco hosts.

In terms of the new sales model, Cisco CEO Chuck Robbins said the key idea is to provide greater flexibility in how customers consume the technology. Cisco cited Google and Facebook as partners who are interested in disaggregated solutions.

Microsoft is testing the use of its SoNIC technology in conjunction with the Cisco 8000 platform.

“Innovation requires focused investment, the right team and a culture that values imagination," said Chuck Robbins, chairman and CEO of Cisco. "We are dedicated to transforming the industry to build a new internet for the 5G era. Our latest solutions in silicon, optics and software represent the continued innovation we're driving that helps our customers stay ahead of the curve and create new, groundbreaking experiences for their customers and end users for decades to come.”

FCC kicks off mmWave spectrum auction

The FCC commenced the next of its 5G auctions, with bidding on spectrum in the upper 37 GHz, 39 GHz, and 47 GHz bands (Auction 103).  The FCC is making 3,400 MHz of millimeter-wave spectrum available through this auction. 

Auction 103 will offer 14,144 Upper Microwave Flexible Use Service licenses in the Upper 37 GHz, 39 GHz, and 47 GHz bands, and the licenses will be based on Partial Economic Areas (PEAs). Category M/N consists of blocks in 37.6 – 40 GHz, including 10 blocks (Blocks M1–M10) in the Upper 37 GHz band and 14 blocks (Blocks N1–N14) in the 39 GHz band; and Category P consists of 10 blocks (Blocks P1–P10) in 47.2 – 48.2 GHz, the 47 GHz band.

Current auctions are posted here: https://www.fcc.gov/auction/103/round-results

“Today’s spectrum auction shows that America is continuing to lead the world in 5G, the next generation of wireless connectivity.  These airwaves will be critical in deploying 5G services and applications.  Auctioning the 39 GHz and upper 37 GHz bands together presents a critical opportunity for 5G deployment as it represents the largest amount of contiguous spectrum available in the millimeter-wave bands," stated FCC Chairman Ajit Pai.

“Notably, we’re setting up the Upper 37 GHz, 39 GHz, and 47 GHz auction to be our second-ever incentive auction.  This one will be different from the broadcast incentive auction that Congress authorized years ago, but it’ll have the same worthy goal: clearing or repacking existing licensees to make spectrum as useful as possible, boosting competition and benefiting consumers.

“Pushing more spectrum into the commercial marketplace is a key component of our 5G FAST plan to advance American leadership in the next generation of wireless connectivity.  Earlier this year, we concluded our first-ever high-band 5G auctions of the 28 GHz and 24 GHz bands. Next year, we look forward to initiating two mid-band spectrum auctions—the 3.5 GHz auction on June 25, 2020, and an auction in the 3.7-4.2 GHz band in the latter part of 2020.  These and other steps will help us stay ahead of the spectrum curve and allow wireless innovation to thrive on our shores.”
