The conversation focused on the uplink and downlink interference limits established in the Commission‘s Memorandum Opinion and Order and Second Order on Reconsideration ("MO&O") in Docket No. 01—185, and the relationship between the limits adopted in that order and the terms of the ATC license issued to MSV in DA 04—3553. More specifically, we discussed (}) the relationship between the technical parameters underlying the 1999 L—band Operating Agreement and the technical limits adopted in the MO&O, (i) the impact under the new rules of new coordination agreements under the Mexico City MOU, (ii) the amount ofinterference than can be generated by the ATC component of an MSS/ATC system, (v) the Commission‘s process for allowing interested parties to review filings under the new ATC rules, (v) the Commission‘s process for resoving ATC interference disputes, (vi)the increased level of protection provided to MSS receivers in the 1544—1545 MHz band, (vi) the new rule requiring ATC proponents to provide affected L band users notice ofpossible intermodulation issues, (vii) the reference bandwidth contained the technical limits on ATC base station power levels, (ix) the Commission‘s assumptions about the amount ofL—Band spectrum to which MSV has access, and (x)the status ofcoordination under the Mexico City MOU.
