This, in turn, will expedite the provision of satellite services to consumers and enhancing the types of services available, without increasing the likelihood of harmful interference to adjacent satellite operators or to terrestrial wireless operators. Rules That the Commission Amended oThe Commission adopted off-axis EIRP envelopesfor routine earth station operators in the Fixed Satellite Service (FSS) (47 C.F.R. § 25.218). Previously, to be considered routine, all earth station applicants were required to meet specific input power level and antenna gain performance standards. Under this new rule, applicants choosing the off- axis EIRP option can offset changes in input power level with changes in antenna gain, and still receive routine treatment. Impact on Small Business This new rule will have no

  • also contends that Row 44 did not properly account for the effect of aircraft banking on antenna misorientation. Furthermore, ViaSat argues that Row 44 AESs will have to operate with higher than specified amplifier output power in order to maintain an adequate signal/noise margin, and will consequently generate off-axis EIRP density in excess of the pertinent envelope specified in Sections 25.218 and 25.222 even if pointing error is kept within 0.2 degrees. As noted above, Row 44 tested its proposed AMSS system to determine whether or to what extent its system would cause harmful interference to adjacent satellite operators under normal flight conditions. Row 44 filed reports of its test results pursuant to requests for confidentiality on April 13 and May
