allow AT&T to use the PSD model at a maximum ERP level of 125 watts/MHz in four Missouri cellular market areas. AT&T can potentially increase the power to 250 watts/MHz in nonrural areas and 500 Watts/MHz in rural areas, said the order in docket 15-86. AT&T told the FCC that granting the waiver would help it build out its LTE network more quickly. The bureau said it had earlier approved similar waivers for AT&T in Vermont and Florida. “We find it persuasive that AT&T and several public safety entities previously conducted successful tests using the PSD model, and that no public safety licensees have raised objections specific to AT&T’s proposed PSD model for the Missouri Stations or requested testing,” the bureau said. “Further, the conditions we impose will help ensure that public safety systems and neighboring Cellular licensees will be protected from increased harmful interference from AT&T’s operations using the PSD model.” Among conditions imposed is a notice requirement for public safety agencies with nearby operations using 806-824 MHz/851-869 MHz before the carrier deploys a base station.
