("MSV") hereby files the attached Affidavit from LCC International Inc., a recognized leader in wireless network design, explaining how MSV will always be able to determine the number of base stations and the on-the-air traffic operating on its licensed frequencies both within and outside of the United States at any given time. This Affidavit demonstrates that the Commission can allow MSV to use over 50% of its authorized system-wide co-channel reuse in the United States while ensuring that MSV does not exceed a system-wide co-channel reuse allowance.' Please direct any questions regarding this matter to the undersigned.

Affidavit of LCC International Inc. on the Ability of MSV to tolo\* the Number of ATC Base Stations Usine Its Licensed Frequencies Tliroughout Ita Coverage Area I. ’Illis affidavit will address how Mohile Satellite Ventures t.,P (“MSV”) will be able to asccrtitin the number of Ancillary Terrestrial Component (“ATC”) base stations and periodic determination of on-the-air traflic that use its licensed ficquencies throughout the United States artd C:ilnada. 2. We understand, bawd on information provided to us by MSV. that (a) AI’C presently is only authorized in the Unitcul States and Caitada, (b) as in the United States, AIC: in C’anada itiust he integrated under the control ofthe satcllitc operator, (c) MSV‘s hybrid satellitdA1’C: iictwork will use the s a n e frequencies fi,r the siitellite and torrestrial components throughout the l.ntied States anti Canada, (d) these are the irequcncics that MSV rind MSV Canada has coordinated under the Mexico City Memorandurn oflinderstanding, ( e ) MSV’s satellite and terrestrial infrastructure will he under the central control of a dynamic radio resource manager that allocates and distributes frequcnciw between the tencxrial and satellite portions in real time, 3. W e also understand, based on information provided to us by MSV. thdt there will also he cl system ot‘ switches that are networked togethcr and monitored at a central control p l h t (the Network Operations Center ~NCX?’)), and the ATC will include mrtny switches, or Mohile Switching Centers (“MSCs”), optimally distributed throughout the United States and Canada. All of these disparate switches may bc networked together. The networking may include inter- switch trunks that may be used litr intra-network infonnation transfer, call setup and handover

between different components of the syslcnr, frequency management, and rcal-time coordination for silktying dynamic prioritization and preemption requirements. 4. This entire distributed network of switches may be monitored and managed from a central point o f control ..-. the NOC. At the NOC. MSV will be able to obtain the number of bast: static)ns and periodic deterniination of on-the-air traffic using its licensed frequencies both within and oulsitle ofthe linited States. 5, Based on data conrpiletl in real time at the NOC', using this wnligiiration. MSV will be able to provide the FCC' upon request with the (i) number o f b a x stations and periodic detinninntion of on-the-ail- tlafEc using its licensed frequencies both withiii and outside ofthe l!nitetl States and (ii) the precise locatioiis of those base stations. l,C(y IN'rERNA'lTIONAI,.
