MSV's MSS with ATC Presented to the FCC on December II, 2003 TsMSV -- ="- -7 M o b i l e Satellite Ventures

MSV’s First Generation MSS with ATC ATC Efficient spectrum reuse Mass-market standards (e. g., CDMA, GSM) Fully integrated end-user device with companion antenna booster

MSV’s Next Generation MSS with ATC Next generation satellite system with ATC Higher spectrum reuse efficiency - Many more satellite spot beams Mass-market standards (e. g., COMA, GSM) End-user device remains fully integrated and no longer nee!ds a companion antenna booster ;MSV - r s i . - =”- - Mobile Satellite Ventures

Key Issues ATIT - Up to 6% should be allowed for the ATC - Irrefutably defendable (less than 0.2 dB of link margin loss) - The satellite ATlT impact is dropping like a rock Cochannel vs. non-cochannel - Non-cochannel frequencies should be exempt from reuse restrictions - Non-cochannel frequencies cannot be interfered with Overload Threshold of lnmarsat METs - All measurements indicate that more than -45 dBm of power is needed to cause overload

Waiver Requests Increase of cochannel reuse up to 6% AT/T - Unlimited reuse of non-cochannel frequencies Increase of base station ElRP per sector by 15 dB - Eliminate limit on number of carriers per sector Increase base station PFD limit by 15 dB at airport runwayslstand areas and at waterways Reduce base station overhead gain suppression - Less than 0.03 dB impact to airborne METs Eliminate limit on aggregate adjacent channel traffic FsMSV s= Mobile Satellite Ventures
