Representatives of Vulcan Wireless met with FCC Commissioner Ajit Pai...

proceeding,” they said in an ex parte filing (http://xrl.us/bnj7tn). “Rather, the Commission need only adopt an order requiring interoperability across all paired spectrum blocks in the Lower 700 MHz band, and allow interested parties to cooperatively use the industry-driven standards body process to determine the best technical manner to implement an interoperability requirement. Under this approach, the Commission would ensure that a unified band plan is adopted and ratified within a reasonable time period, not to exceed six months (in which case Band Class 12 would become the de facto standard if a new, unified standard is not adopted and ratified).” The Vulcan representatives also weighed in on the very test results that have been submitted to the FCC on whether a single band would pose an interference risk to some licensees. “The only reliable technical evidence submitted to the record in this proceeding demonstrates that Lower 700 MHz interoperability will not adversely impact Lower B and C Block device reception,” the filing said. “By contrast, opponents of Lower 700 MHz interoperability have not provided any reliable measurements or empirical data to support their unsubstantiated claims of interference. Rather, they have only submitted data derived from very limited, fundamentally flawed, and corrupted test designs that fail to reflect real world device and network performance."
