20100727M02V01_Filing_Notes.doc 1 FCC Filing Notes On-The-Move SATCOM Permanent Licensing Form 312, Schedule B E10: Our earth station is mobile with operation within CONUS and Hawaii. We are excluding transmissions near White Sands, NM in order to not interfere with government operations in that area. • Mobile-CONUS • 14.0 to 14.5 GHz • No transmissions between 14.0 GHz and 14.2 GHz within 125 km of o White Sands, NM ƒ latitude: 32.5430N, longitude 106.6121W ƒ latitude: 32.5008N, longitude 106.6086W o Blossom Point, MD ƒ latitude: 38.4289N, longitude 77.0839W E11,12,14: Since this is a mobile satellite earth station we are leaving the coordinates completely empty and have indicated CONUS coverage in E10. The elevation is left blank since it will vary. E29: While we anticipate filing for a blanket license in the future, the current filing is intended to be for ONE mobile satellite earth station. We understand that there are additional rules that we need to address for a blanket license. We expect to be able to comply with the blanket license rulings, but would like to review these in detail and prepare a future filing. For now the filing is for ONE mobile satellite earth station only. E32, 33, 34: Antenna Patterns are included in the technical brief. These patterns are for the L3/Datron FSS-4180-LP Antenna Assembly which is an elliptical antenna with the following attributes: E32: Diameter (meters): 0.36 (equivalent diameter) E33: Diameter Minor (meters): 0.30 E34: Diameter Major (meters): 0.44 E33 and E34 are actual dimensions. For E32 we put the equivalent diameter (ie. as if it were circular). E35: The antenna will typically be mounted on top of a vehicle with a height of about 1-2 meters. We have indicated a maximum height of 3 meters to include the antenna height as well as that of the vehicle. E36, 37, 39: Since this is a mobile satellite earth station the height field is left blank since it will vary. E48, 49: For receive carriers we have left the EIRP field blank. E49 Maximum EIRP Density per Carrier: A range of transmit emissions are possible with an average EIRP density of 11.1 dBW/4kHz. Only ONE carrier type will be transmitted at any one time. Following is a list of carrier types that cover the minimum and maximum bandwidths and the minimum and maximum EIRPs. iNTELLICOM Satellite & Wireless Engineering and Management www.ITCcom.net

20100727M02V01_Filing_Notes.doc 2 E56, 57, 58, 59 Frequency Coord: The radiation safety report (04_20090915MV05_FSS4180LP_Rad_Hazard.pdf) describes the built-in safety controls on low elevation transmissions. Radiation safety calculations are shown for emissions down to low elevation angles which may NOT be needed in some operational scenarios. For the satellites and CONUS operation requested in this license the lowest elevation angle is 10 degrees and this occurs at Caribou, Maine while pointing at IA7 at 129 degrees W. We have examined the azimuth and elevation angles for locations within CONUS to determine the extremities for eastern and western satellite limits.
