This transition plan provides for the replacement of those remaining links with commercially-leasedbandwidth. Details:Two remaining sites employ microwave relay links in the band 1755-1780 MHz: Los Angeles/Oxnard, California, and Missoula, Montana.Uponreceipt of transition funds, NOAA/NWS will undertake to lease necessary point-to-point bandwidth and remove the associated government-ownedmicrowave equipment. As the currently-installed equipment is considered to have remaining economic lifetime in excess of five-years, NOAA/NWS isseeking reimbursement for estimated installation and recurring lease costs for five years. (The Los Angeles/Oxnard link will be given priority forremoval/replacement owing to that region's high rank in the list of economic areas being offered to commercial wireless entities.) Note: For simplicity, the authorized AOA for assignments C131126, C131146, and C131148 is provided in Tab C (column I) as the radius (in km) of a circlecentered on the given TX/RX latitude/longitude that circumscribes the actual authorization which was defined by polygons; thus, the actual authorizationcovers a smaller overall area than implied by the point/circle definition.
