  2. WRC-12 • January 23 – February 17, 2012 • (moved from September 2011) • Held in Geneva, Switzerland • Conference Preparatory Meeting held in Geneva February 14-25, 2011 • Deals with 35 separate Agenda Items, considering potential changes to the ITU Radio Regulations, a treaty-level instrument containing the international table of allocations and rules governing the various radio services. • The ARRL CTO’s office is tasked with, among other things, international advocacy. This primarily, but not exclusively, involves advocacy before the ITU and preparation for international meetings, such as WRC-12.

  3. Agenda Item 1.19 • To consider regulatory measures and their relevance, in order to enable the introduction of software-defined radio and cognitive radio systems, based on the results of ITU-R studies, in accordance with Resolution 956 (WRC-07).

  4. SDR Definition • Software-defined radio (SDR) is a radio transmitter and/or receiver employing a technology that allows the RF operating parameters including, but not limited to, frequency range, modulation type, or output power to be set or altered by software, excluding changes to operating parameters which occur during the normal pre-installed and predetermined operation of a radio according to a system specification or standard.

  5. CRS Definition • Cognitive radio system (CRS) is a radio system employing technology that allows the system to obtain knowledge of its operational and geographical environment, established policies and its internal state; to dynamically and autonomously adjust its operational parameters and protocols according to its obtained knowledge in order to achieve predefined objectives; and to learn from the results obtained.

  6. SDR CPM Method • “Any radio station that has been reconfigured must continue to meet the regulatory requirements in the Radio Regulations applicable to the radio service in which the radio station belongs. Whether the reconfiguration is made by hardware or software means does not negate that requirement. Therefore it becomes clear that the existing Radio Regulations can encompass the implementation of SDR without any modification to the Radio Regulations.” 6/1.19/5.1.1 Method A No change to the Radio Regulations. Under this method, technical and operational considerations related to the SDR technologies implemented in any stations of a radiocommunication service would be addressed in ITU-R texts as appropriate. Advantages – Allows administrations to facilitate implementation of SDR. Disadvantages – None.

  7. CRS CPM Methods 6/1.19/5.2.1.1 Option A: No change to the Radio Regulations Under this method, technical and operational considerations related to the CRS technologies implemented in any systems of a radiocommunication service could be developed in ITU-R Recommendations and Reports as appropriate. Advantages – Allows administration to facilitate implementation of CRS. Disadvantages – Does not provide guidance for the studies and provisions for the implementation of CRS. 6/1.19/5.2.1.2 Option B: No change to the Radio Regulations and an ITU-R Resolution providing guidance for further studies on CRS Under this method an ITU-R Resolution is developed to provide a framework in order to facilitate studies on technical and operational considerations related to the implementation of CRS technologies to ensure coexistence and sharing among radiocommunication services are addressed leading to ITU-R Recommendations and Reports as appropriate. Advantages – Allows administrations to facilitate implementation of CRS. – Resolution provides a framework for guidance on further studies. Disadvantages – Does not provide provisions for the implementation of CRS.

  8. Caveat • The value of the CPM Report today is {x | x > 0}. • The value of the CPM Report on January 23, 2012 is {x | x = 0}.

  9. What else is going on with WRC-12 preparation? • Defensively, we are working on HF and VHF radar and monitoring other issues. • Offensively, we are working on a secondary allocation between 415-526.5 kHz. The United States has taken an affirmative position on this item despite significant opposition by maritime interests. • WRC-12 will determine the agenda for WRC-15. It is a near certainty that a reallocation for mobile broadband/IMT will be on the WRC-15 agenda.
