Mobile-Satellite Service at 148-149.9 MHz

By this action, we deny a Petition for Reconsideration filed by STARSYS, Inc. (STARSYS). In its petition, STARSYS requests either that the Commission increase the permissible duty cycle from 0.25% to 1.0% per 15 minute interval for those systems in the low-Earth orbit (LEO) mobile-satellite service (MSS) operating in the 148-149.9 MHz band that use code division multiple access (CDMA) spread spectrum systems and which do not utilize a system that avoids frequencies used by other services in [[Page 20910]] this band, or in the alternative, that the Commission exempt from the duty cycle limitation CDMA systems operating below a certain power density. We are taking this action because we continue to believe that the power density and duty cycle requirements we adopted are necessary to prevent interference to incumbent government fixed and mobile operations that will share this band with LEO MSS on a co-primary basis.
