NSN Sees 5G Viability in Authorized Shared Access (ASA) with TD-LTE Spectrum

Nokia Solutions and Networks demonstrated the viability of Authorized Shared Access (ASA) -- a new technology that enables dynamic access to underutilized spectrum frequencies.

NSN describes ASA and spectrum sharing as enabling technology for 5G. The idea is for mobile operators to share frequency bands from other types of incumbent systems, such as government agencies or TV broadcast networks, while guaranteeing quality of service for both.

Earlier this year, NSN and CORE+ consortium took a giant leap forward with the worlds’ first spectrum sharing trial of ASA on a live 2.3GHz TD-LTE network. For the live trial, NSN deployed its network elements in three Finnish cities: commercial Single RAN Flexi MultiRadio 10 Base Stations in Ylivieska, commercial Core Network in Oulu and commercial NetAct network management system in Tampere.

“The benefit of ASA is that it provides both the technology and regulatory framework for sharing spectrum”, said Marc Rouanne, executive vice president, Mobile Broadband at NSN. “Our trial showed that operators can get up to 18% extra bandwidth for mobile broadband networks cost effectively. This technology works with existing LTE and TD-LTE networks and does not require specific software for the end-user devices, making it easy to deploy and transfer the benefit directly to the mobile customers.”

Presentation here:

In June 2013, a U.S. Spectrum Policy Team was formed to accelerate spectrum sharing policies and technologies. The Spectrum Policy Team will draft recommendations on how NTIA and FCC can incorporate spectrum sharing into their spectrum management practices to enable more productive uses of spectrum throughout our economy and society and protect the current and future mission capabilities of federal agencies. The team consists of the Chief Technology Officer and the Director of the National Economic Council, along with representatives from the Office of Management and Budget (OMB), the National Security Staff, and the Council of Economic Advisers.

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.

FCC Reviews Wireless Infrastructure Policies for Small Cells and DAS

The FCC will undertake a review of its wireless infrastructure policies with a goal to reduce obstacles to obtaining access to rights-of-way and locations for wireless facilities.

Specifically, the FCC is seeking comment on:

  • Streamlining the environmental and historic preservation review processes for newer technologies, including small cells and distributed antenna systems;

  • Removing barriers to the deployment of temporary towers, that are used in cases of emergencies or to add capacity during short term events;
  • The meaning of terms included in a provision of the Middle Class Tax Relief and Job Creation Act of 2012 which states "a State or local government may not deny, and shall approve, any eligible facilities request for a modification of an existing wireless tower or base station that does not substantially change the physical dimensions of such tower or base station;" and
  • Clarification of issues addressed in the Commission's "shot clock" order which set time periods for state and local governments to complete review of wireless siting applications. 

The FCC said increasing certainty in its processes and removing barriers to infrastructure deployment will spur public and private investment, while expanding wireless coverage and capacity.

FCC Acting Chairwoman Mignon L. Clyburn stated: "Today, we seek comment on how we can change our processes to encourage greater deployment of new technologies such as small cells and Distributed Antenna Systems. These innovative solutions multiply wireless capacity within existing spectrum resources and can be deployed relatively easily and inexpensively by consumers, enterprise users, and service providers. These newer technologies can be deployed on utility poles, street lamps, water towers, or rooftops -- a big reason why they are becoming more common. The time is ripe for the Commission to look at updating our rules for these new technologies."

FCC to Require Mobile Operators to Disclose Network Availability after Disasters

The FCC is proposing new rules that would require wireless service providers to publicly disclose the
percentage of cell sites within their networks that are operational during and immediately after disasters. 

The FCC said its goal is to provide consumers with a yardstick for comparing wireless performance in emergencies. The rules also seek to encourage competition in the wireless industry to improve network reliability. 

The FCC's proposal would require wireless service providers to submit to the FCC, for public disclosure on 
a daily basis during and immediately after disasters, the percentage of operational cell sites for each county 
within a designated disaster area.

Gogo In-flight Wi-Fi Now on 2,000 Commercial Aircraft

Gogo hit a major milestone by installing its 2000th commercial aircraft with its in-flight Internet service.

Out of the 2,000 aircraft installed with Gogo's in-flight Internet service, more than 300 have now been equipped with the company's next generation service – ATG-4 – that increases peak bandwidth to the aircraft by more than three times Gogo's original service.  The company expects to have more than 500 Gogo equipped aircraft outfitted with ATG-4 by the end of this year.

  • Earlier this month, Gogo announced plans to deploy a proprietary, hybrid Ground-to-Orbit architecture by the second half of next year that would combine existing satellite technologies with its Air to Ground (ATG) cellular network.  The technology will use satellite for receive only (transmission to the plane) and Gogo's Air to Ground network for the return link (transmission to the ground).  Gogo will be utilizing a Ku antenna developed specifically for receive only functionality.

Fujitsu Boosts Energy Efficiency in Base Station Power Amplifier

Fujitsu Laboratories has developed a circuit technology that enables industry-leading electrical efficiency for wireless transmission power amplifiers used in radio-frequency wireless devices, such as mobile phone base stations.

Fujitsu Laboratories has developed a compact, low-loss power combining circuit along with a high-precision phase error compensation technology based on digital signal processing. These technologies enable high-efficiency transmissions across more than 95% of the transmission duration, compared with 65% for existing amplifiers. In addition, Fujitsu Laboratories succeeded at developing a prototype transmitter power amplifier with a peak output power of 100 W. This development improved average electrical efficiency during transmission, from the current rate of around 50%, to 70%(2).

Fujitsu said its new technology will help pave the way toward lower energy consumption for mobile phone base stations and other radio-frequency wireless equipment.
