24. AGENDA ITEM 1.20 WHAT: Protection of the EESS (passive) from unwanted emissions WHY: Vital U.S. interests both in passive sensing and in services that could cause interference (fixed service, radars, fixed-satellite service uplinks, etc.) U.S. POSITION: NOC for some bands/services and non-mandatory limits for some bands to protect remote sensing OUTCOME: Combination of non-mandatory/mandatory limits based on feasibility and importance of protection. Non- mandatory for all services around 1400-1427 MHz and FSS in 30-31 GHz. Mandatory limits on active services in all other bands with phased implementation dates

26. AGENDA ITEM 7.2 WHAT: Future Conference Agenda 2011. WHY: Agenda Item 7.2 deals solely with developing a Resolution containing the recommended agenda for the next two conferences (i.e., WRC-11 & WRC-15). U.S. POSITION: The United States had several proposals for this agenda item, including both additions and those we wanted to suppress or modify to reduce the risk associated with them.
