FCC Proposes Dynamic Spectrum Sharing in 3.5GHz Band for Citizens Broadband Radio

The FCC outlined a proposal for a New Citizens Broadband Radio Service in 3.5 GHz band.

The idea would be to designate 3.5 GHz spectrum as an "innovation band" for exploring new methods of spectrum sharing and promote a diverse array of network technologies, with a focus on relatively low-powered applications.

The FCC is proposing a three-tier authorization framework under which existing primary operations – including authorized federal users and grandfathered FSS earth stations - would
make up the Incumbent Access tier and would receive protection from harmful interference. The Citizens Broadband Radio Service would be divided into Priority Access and General Authorized Access (GAA) tiers of service, each of which would be required to operate on a non-interference basis with the Incumbent Access tier. The FCC is also proposing that any party that meets basic eligibility requirements under the Communications Act be eligible to hold a PAL or, when authorized, operate a CBSD on a GAA basis in the Citizens Broadband Radio Service.

The FCC noted that this proposed three-tier framework enjoys significant support from a diverse group of commenters, including AT&T, Google, Public Knowledge, and the Open Technology Institute at the New America Foundation. Others, including CTIA – The Wireless Association (CTIA), NSN, and Qualcomm have argued that a two-tier framework that would prohibit or segregate GAA users would be a more efficient way to manage the 3.5 GHz Band.

Under the FCC proposal, in place of fixed channel assignments, a Spectrum Access System (SAS) would dynamically assign bandwidth within given geographic areas to Priority Access Licensees and GAA users. The SAS would ensure that Priority Access Licensees have access to allotted 10 megahertz channels and that GAA users are provided access to at least 50 percent of the band. However, the exact spectral location of any given authorization, whether Priority Access or GAA, would not be fixed. For example, a licensee might have Priority Access rights for a single PAL, but the specific channel location assigned to that user would be managed by the SAS and could be reassigned from time to time (e.g., from 3550-3560 MHz to 3630-3640 MHz). Individual GAA users would be assigned available bandwidth of a size and spectral location determined by the SAS (e.g., from 3550-3556 MHz or 3662-3673 MHz).

Additional background:


In July 2012, the President’s Council of Advisors on Science and Technology (PCAST) issued a report identifying 1,000 MHz of federal spectrum for sharing with the private sector.

U.S. federal policy should shift in favor "Shared-Use Spectrum Superhighways" instead the current plan which is to first clear federal users from specific bands and then auction this spectrum for the exclusive use of the highest bidder, according to a new report issued by

A Presidential memorandum issued in June 2010 requires that 500 MHz of spectrum to be made available for commercial use within 10 years.  However, a recent NTIA Study found that clearing just one 95 MHz band will take 10 years, cost $18 billion, and cause significant disruption. Moreover, the net revenue for the Treasury from the last successful auction of 45 MHz realized a net income of just a few hundred million a year ($5.3 billion total).

The PCAST report said its vision of shared spectrum is viable using existing technologies and is not dependent on cognitive or "smart" radios. Instead, a geo-location database could be used the share spectrum much like how the FCC is using managing TV bands. The TV Whitespaces system could be used as a model. Technical standards would need to be implemented for coexistence of transmitters and receivers to enable flexible sharing.

IBM Unveils Power Systems Servers for Scale-Out, Big Data

IBM unveiled its new line of high-performance, Power Systems servers based on its own POWER8 processor and designed for the era of Big Data.

IBM said the new servers, which represent a $2.4 billion investment and three-plus years of development, leverage new silicon with more than 4 billion transistors and more than 11 miles of high-speed copper wiring.  IBM calculates that its new Power Systems are capable of analyzing data 50 times faster than the latest x86-based systems, and certain analytics processes can be run 1,000 times faster.

The Power Systems servers will run various Linux implementations, including Ubuntu Server 14.04 LTS, Ubuntu OpenStack and Juju service orchestration tools.  They will also support PowerKVM, a Power Systems-compatible version of the popular Linux-based virtualization platform KVM, as well as Red Hat and SUSE Linux. The first POWER8-based systems to debut are five Power Systems S-Class servers designed for large, scale-out computing environments.

"This is the first truly disruptive advancement in high-end server technology in decades, with radical technology changes and the full support of an open server ecosystem that will seamlessly lead our clients into this world of massive data volumes and complexity," said Tom Rosamilia, Senior Vice President, IBM Systems and Technology Group. "There no longer is a one-size-fits-all approach to scale out a data center. With our membership in the OpenPOWER Foundation, IBM's POWER8 processor will become a catalyst for emerging applications and an open innovation platform."

IBM's POWER architecture is the cornerstone of innovation for the OpenPOWER Foundation, which also includes participation of Google, NVIDIA, Mellanox, Tyan and over 20 others.

Infonetics: Networking ports hit $39 billion in 2013

Worldwide 1G/10G/40G/100G network port revenue grew 5% in 2013 from the prior year, to $39 billion, according to a new report from Infonetics Research.

“Deployments of 1G, 10G, 40G, and 100G ports once again grew significantly in 2013, as enterprises and service providers invested in their networks to accommodate the growth in traffic, and revenue growth accelerated as buyers shifted to higher bandwidth—and more expensive—ports,” reports Matthias Machowinski, directing analyst for enterprise networks and video at Infonetics Research.

Principal Analyst for Optical at Infonetics and co-author of the report Andrew Schmitt adds: “Coherent 100G is well on its way to completely taking over the core, growing to nearly 80% of all wavelengths by 2016, effectively shutting down competing 10G and 40G deployments.”

Some report highlights:

  • Enterprise port revenue grew 5%, and service provider port revenue increased 4%
  • 1G comprises the lion’s share of ports, while 10G delivers the bulk of revenue, though revenue growth is coming from the emerging 40G and 100G segments
  • The 40G market is in transition as service providers move on to 100G; 40G is, however, finding success in the data center market, resulting in 40G port shipments more than doubling in 2013
  • Infonetics looks for 40G port shipments to nearly triple this year, hitting 1.5 million
  • 100G ports almost quadrupled in 2013, thanks to surging service provider demand for 100G WDM
  • The first 100G ports on enterprise equipment started shipping in 2013, but aren’t expected to become a major factor until 2015.
