Orbital Location ) ORDER AND AUTHORIZATION Adopted: December 22, 2006 Released: December 22, 2006 By the Chief, Satellite Division, International Bureau: L. INTRODUCTION 1. By this Order, we authorize EchoStar Satellite Operating Corporation (EchoStar) to operate the EchoStar 9 satellite in 400 megahertz of additional Ka—band spectrum at the 121° W.L. orbital location. Specifically, we authorize EchoStar to operate EchoStar 9 in the 18.3—18.5 GHz, 18.6—18.8 GHz, 28.4—28.6 GHz, and 29.3—29.5 GHz frequencies, in addition to the previously authorized 29.5—30.0 GHz and 19.7—20.2 GHz frequencies. We also grant EchoStar‘s request for waivers of two of the Commislsion’s rules. Finally, we dismiss EchoStar‘s pending application for special temporary authority as moot. IL BACKGROUND 2. The EchoStar 9 satellite, a hybrid Ku—/Ka—band satellite, was launched in 2003 and is currently located at the 121° W.L. orbital location." EchoStar 9 is authorized to operate in the "upper" half of the 1000 megahertz of Ka—band spectrum ("upper Ka—band") allocated in both transmission directions to the Fixed—Satellite Service (FSS). When the "lower Ka—band" became available for ‘ See IBFS File No. SAT—STA—20050608—001 16. * See EchoStar KuX Corporation, Application for Authority to Construct, Launch and Operate a Geostationary Satellite Using the Extended Ku—band Frequencies in the Fixed—Satellite Service at the 121° W.L. Orbital Location, Order and Authorization, 20 FCC Red 942 (2005); EchoStar Satellite Corporation, Order and Authorization, 18 FCC Red 15862 (2003) (granting EchoStar‘s request to modify its Fixed—Satellite Service (FSS) Ka—band license at 121° W.L. to permit hybrid Ka—/Ku—band operations); EchoStar Satellite Corporation, Order and Authorization, 13 FCC Red 5664 (1996) (granting EchoStar‘s application to launch and operate a FSS satellite in the Ka—band at the 121° W.L. orbital location).

Federal Communications Commission DA 06—2590 reassignment, EchoStar filed a modification application‘ to add these frequencies to its license for a next— generation Ku—/Ka—band satellite which is scheduled for launch in 2009 and will be located at the 121° W.L. orbital location. The Commission granted this modification application in August 2005." On August 30, 2006, EchoStar filed the instant application to add 400 MHz of the lower Ka—band frequencies‘ to an existing payload on its EchoStar 9 satellite." The application was placed on public notice as accepted for filing on September 29, 2006."‘ In addition, EchoStar seeks waivers of Sections 25.210(d) and 25.210(i) of the Commission‘s rules. No comments were filed. IIL DISCUSSION A. Full Frequency Reuse 3. Section 25.210(d) of the Commission‘s rules requires that all FSS space stations employ state—of—the—art full—frequency reuse cither through the use of orthogonal polarizations within the same beam and/or through the use of spatially independent beams." According to EchoStar, the EchoStar 9 satellite is able to achieve full—frequency reuse in the uplinks for Channels A and B in the upper 500 megahertz of the Ka—band, but not in Channels C and D in the lower 500 megahertz ofthe Ka—band." EchoStar contends that grant of this waiver is in the public interest because it would allow EchoStar to use 400 megahertz of spectrum that otherwise will not be used until EchoStar launches its next—generation Ku—/Ka—band satellite in 2009. 4. The Commission may waive a rule for good cause shown.‘‘ Waiver is appropriate if special circumstances warrant a deviation from the general rule and such deviation would better serve the public interest than would strict adherence to the general rule." Generally, the Commission may grant a waiver ofits rules in a particular case if the relief requested would not undermine the policy objective of the rule in question and would otherwise serve the public interest." 5. The full—frequency reuse requirements were desi‘gned to ensure that satellites maximize the use of their transponder capacity to the benefit of the public.‘" The Commission has waived these * See IBFS File No. SAT—MOD—20050617—00127. * See EchoStar Satellite LLC, Grant Stamp, IBFS File No. SAT—MOD—20050617—00127 (August 15, 2005). 5 Specifically, these frequencies are 18.3—18.5 GHz, 18.6—18.8 GHz, 28.4—28.6 GHz, and 29.3—29.5 GHz. ° IBFS File No. SAT—MOD—20060830—00092 (Application}. * See International Bureau, Policy Branch Information: Satellite Space Applications Accepted for Filing, Public Notice, Report No. SAT—00390 (rel.

Federal Communications Commission DA 06—2590 requirements where doing so would allow for the use of satellite capacity that would not otherwise be used, and as long as such use does not preclude a satellite which is capable offull—frequency reuse from operating."" We agree with EchoStar that granting this waiver will allow EchoStar to provide service using 400 megahertz of spectrum that will not otherwise be used until EchoStar launches its authorized next—generation Ku—/Ka—band satellite. We therefore find thatit is in the public interest to waive Section 25.210(d) of our rules. As a condition of the waiver, however, EchoStar shall claim no more protection against interference to its operations from other licensed radiocommunication systems operating in accordance with the Commission‘s rules than if it was able to achieve full—frequency reuse in all ofits transmissions. B. Cross—Polarization Isolation 6. Section 25.210(i) of the Commission‘s rules requires space station antennas in the FSS to be designed to meet a cross—polarization isolation of 30 dB within the primary coverage area of the antenna.‘" EchoStar states that the EchoStar 9 satellite‘s antennas are designed to meet a cross— polarization isolation of 22 dB for the downlink bands and 20 dB for the uplink bands."" 7. Section 25.210(i)‘s cross—polarization isolation requirement facilitates two—degree orbital spacing between geostationary satellites, which is a cornerstone of the Commission‘s satellite licensing policies."" This policy permits the maximum use ofthe geostationary orbit, The Commission, however, adopted the cross—polarization isolation requirement in an environment where satellites were predominantly using analog transmissions. Along with the C—band analog video frequency plan of Section 25.211(a)"" and the polarization switchability requirement of Section 25.210(c)"", the cross— polarization requirement serves to minimize the interference between adjacent satellites when both are carrying analog video signals with highly peaked spectra. In addition, the cross polarization requirement serves to limit the level of self—interference, thus assuring that operators do not allocate an inordinate proportion of the interference budget to themselves. In this context, it is worth noting that the cross polarization performance ofthe satellite receive antenna has no effect on the interference into other systems. Also, in a two—degree spacing environment, the cross—polarization performance of the downlink satellite antenna has only a second—order effect on the interference into the neighboring system."‘ Since " See, eg., Systematics General Corporation, Order and Authorization, 2 FCC Red 7550 (1987) (authorizing the TDRS—1 and TDRS—3 satellites, which did not meet the full frequency reuse requirement, to provide service fro the 41° W.L. and 62° W.L. orbit locations until those locations were ready to be occupied by compliant satellites). See also Columbia Communications Corporation, Memorandum Opinion,Order, and Authorization, 7 FCC Red 122, 123, para. 15 (1991). ©47 CFR. §25.2190). ‘‘ EchoStar Application at 5. * See Application of New Skies Satellites, N.V. for Authorization to Access the U.S. Market, Order and Authorization, 14 FCC Red 13003, 13037 at para. 75 (1999). ©47 CFR. § 25.211(a). * 47 CFR. § 25.210(c). *‘ The impact of the satellite downlink antenna cross polarization performance is to raise slightly the interference level into the downlink of the victim satellite‘s wanted polarization. Thus, the neighboring victim satellite would receive a co—polar interfering signal in its wanted polarization at a level defined by its co—polar earth station sidelobe performance. In addition, in the same polarization, it would receive a much lower interfering signal whose level is defined by the interfering satellite‘s downlink cross—polarization performance. If the sateilite antenna met the 30 dB requirement of 25.210(i) and if it transmitted at the same level in both polarizations, this cross—polar contribution would increase the co—polar interference level by one part per thousand. This increase would correspond to a (Continued....)

Federal Communications Commission DA 06—2590 the EchoStar 9 system uses only digital transmissions, its antennas® non—compliance with our analog cross—polarization isolation requirement should have only a negligible increase in interference to adjacent satellites. 8. We therefore find that it is in the public interest to waive Section 25.210(i) of the Commission‘s rules. As a condition of the waiver, however, EchoStar shall claim no more protection from interference from other licensed radiocommunication systems operating in accordance with the Commission‘s rules than if its antennas were in compliance with Section 25.210(i) of our rules. C. Coordination with Government Operations 9. Ka—band space systems operating in the 18.3—18.8 and 19.7—20.2 GHz bands are required to coordinate with Federal FSS systems, both geostationary and non—geostationary, in accordance with footnote US334 to the U.S. Table of Frequency Allocations."" Accordingly, EchoStar‘s Ka—band authorization is conditioned on this coordination requirement." D. Application for Special Temporary Authority 10. In June 2005, EchoStar filed an application seeking special temporary authority to operate in the same frequencies for which it is being given authority to operate herein."* Because we are granting authority to EchoStar to operate in these frequencies on a regular basis, we dismiss the application for special temporary authority as moot. Iv. CONCLUSION AND ORDERING CLAUSES 11. Accordingly, IT IS ORDERED that the modification application, File No. SAT—MOD— 20060830—00092, IS GRANTED and EchoStar Satellite Operating Corporation IS AUTHORIZED to operate the EchoStar 9 satellite in the 18.3—18.5 GHz, 18.6—18.8 GHz, 19.7—20.2 GHz, 28.4—28.6 GHz, and 29.3—30.0 GHz frequency bands at the 121° W.L. orbital location. 12. IT IS FURTHER ORDERED that, pursuant Section 1.3 of the Commission‘s rules, 47 C.F.R. § 1.3, the request of EchoStar Satellite Operating Corporation for a waiver of Section 25.210(d) of the Commission‘s rules, 47 C.F.R. § 25.210(d), IS GRANTED, with the condition that the EchoStar 9 satellite shall claim no more protection against interference to its operations from other licensed radiocommunication systems operating in accordance with the Commission‘s rules than if it was able to achieve full—frequency reuse in all of its transmissions. 13.

With the EchoStar—9‘s downlink antenna cross—polarization isolation of 22 dB, cross—polar interference contribution would increase to about six parts per thousand, and represent a C/I decrease of 0.03 dB. This level ofincreased interference resulting from the satellite downlink antenna‘s non—compliance remains negligible relative to the main interfering signal. * See also 47 C.F.R. § 2.106. * A licensee may initiate coordination under US334 by submitting a letter request to the Commission. * See International Bureau, Satellite Division, Policy Branch Information: Satellite Space Applications Accepted for Filing, Public Notice, Report No. SAT—00299, rel.
