The Wireless Innovation Forum offered comments on a number of topics specifically addressed in the working document towards a preliminary draft report.
Online PR News – 21-November-2013 – Washington, DC – The Wireless Innovation Forum, a non-profit international industry association dedicated to driving the future of radio communications and systems worldwide, today announced comments and modifications on several topics addressed in the ITU-R Working Party 5A (WP 5A) preliminary draft report on new Cognitive Radio Systems (CRS). The Forum released its comments in a recent document prepared by the Forum’s Regulatory Committee.
The Wireless Innovation Forum offered comments on the working document towards a preliminary draft report. The sections for which the Forum supplied comments, and an excerpt from each section include:
• Cognitive pilot channel (CPC) /Cognitive control channel (CCC)
The Forum proposes that WP 5A reduce the focus on CPC/CCC within the draft report to reflect the changing regulatory and market environment since CPC/CCC was first developed as a concept. Distribution of control information/information relative to CRS deployments should not be restricted to a specific air interface.
• Geolocation databases
Current trials have shown that the use of networked and synchronized databases accessed with device location information can be a critical technology in maximizing incumbent protection by enabling and managing real time access to this spectrum by secondary users on a geographic and temporal basis.
• Applicability to different frequency bands e.g. 3.5GHz
The under-utilisation of spectrum is not a band-specific problem; spectrum is underutilized in several frequency bands where these bands also have the potential for spectrum sharing through CRS means.
• Sensing – secondary user coexistence and potential fallback mechanisms
The use of spectrum sensing technologies to better enable cooperative, opportunistic access should not be discounted in future regulatory and system planning.
• Receiver guidelines/specifications
The use of receiver characteristics should be included as part of the analysis of spectrum allocations.
• Technology/Service neutrality
Technology and service neutrality is required to further enable innovative and efficient use of spectrum.
• Blended infrastructure approach
A blended infrastructure approach will increase in dominance over the coming years.
• Licensing models e.g. Licensed shared access/authorized shared access
Regulatory models should include combinations of licensed and unlicensed, sharing and hierarchical, cooperative and co-existent domains for the optimal utilization of spectrum.
The Forum's Chief Regulatory Officer, Keith Nolan, discussed these topics during the ITU Working Party 5A Seminar on Cognitive Radio Systems and the use of White Spaces held in Geneva, Switzerland on November 18th. Dr. Nolan noted that "the eight key topics chosen by the Forum relating to the further deployment of cognitive radio and white space systems resonated with the participants of the well-attended seminar. In particular, the Forum's focus on the potential applicability of white space technologies in frequency bands beyond the UHF TV band, the need for a stronger focus on receiver specifications and standards to help address the technological and regulatory challenges associated with the deployment of new services adjacent to legacy systems, and how CR-based technologies could both leverage and complement existing deployed systems in a 5G context are examples of the leading-edge challenges being considered by the leaders in the field now."
