paper (http://bit.ly/13y4M6O) in April. TAC was chaired by Tom Wheeler, President Barack Obama’s nominee to be chairman of the FCC. “Receiver performance is a key element to successful use of electromagnetic spectrum, and it supports efforts to enhance receiver performance,” the association said (http://bit.ly/14zplFu). “CTIA believes that the TAC White Paper provides a potential framework for encouraging receiver performance where incentives have not spurred efficiency or accounted for future uses. However, CTIA notes that any initial efforts to implement a new receiver performance benchmark should be carefully tailored, and that a multi-stakeholder group process should be used to explore potential approaches.” The TAC paper laid out an interference limits policy built on power levels called “harm claim thresholds” that a service would be expected to tolerate before a claim of harmful interference could be made. Multi-stakeholder groups would play a big role in developing harm claim thresholds. “CTIA is a strong supporter of the use of multi-stakeholder groups, and has a great deal of experience with them,” the filing said. “Given the varied interests and the need for full engagement in the technical details of any new requirements for receivers, a multi-stakeholder group is the most logical approach to investigate the harm claim threshold approach suggested by the TAC White Paper.” But CTIA also urged the agency to move with care. “While CTIA is supportive of the Commission’s efforts to examine a harm claim thresholds approach, the initial steps in determining its effectiveness and appropriate bands for examination should be carefully tailored,” the filing said. “Existing CMRS spectrum allocations, where spectrum is heavily and efficiently used, are not the most appropriate place for testing these theories. Instead, CTIA suggests the Commission should choose a single new or less efficiently used allocation (or allocations) as a pilot to test the use of harm claims thresholds."
