ARTICLE I. Purposes 1. The purposes of this Protocol are: b. To allow for new assignments in frequency sub-bands allotted as primary for each Administration in the 380-399.9 MHz band within the Sharing Zone defined in this Protocol on an interim basis until a more complete protocol governing both new assignments and existing stations can be negotiated and concluded. 2. This Protocol does not apply to existing stations for fixed and mobile services in the 380-399.9 MHz band within the Sharing Zone defined in this Protocol. 1. For the purpose of this Protocol and as provided for in Article IV of the Agreement, the term Administration or Administrations will refer with equal effect to the National Telecommunications and Information Administration of the Department of Commerce United States of America (hereinafter United States) and to the Secretarνa de Comunicaciones y Transportes of the United Mexican States (hereinafter Mexico). 2.

Each Administration shall ensure that fixed and mobile stations assigned to primary frequency allotments within the Sharing Zone shall be operated on an interim basis in accordance with the effective radiated power (ERP) and antenna height limitations specified in the following table (Table I):
Table I_________________________________________________________________ Average of the Antenna Height Maximum ERP in Any Meters Watts dBm _________________________________________________________________ _______________________________________________________________ Appendices I and II are an integral part of this Protocol. ARTICLE VI. Entry into Force and Termination This Protocol shall enter into force on the date of signature. It shall remain in force until it is replaced by a Protocol governing both new assignments and existing stations, or until it is terminated in accordance with Article VII of the Done at Mexico City this twenty-seventh day of July, 2005, in duplicate, in the English and Spanish languages, both texts being equally authentic.
U.S.-MEXICO SHARING ZONE The Sharing Zone is defined on an interim basis as the area covered by a distance of 145 kilometers (90.1 miles) from the U.S.-Mexico common border into the national territory of each country and includes areas of the Pacific Ocean and the Gulf of Mexico. These areas are enclosed by the boundaries shown on the map to the right and are further defined in Table II.
The following geographic coordinates define the U.S.-Mexico Sharing Zone on an interim basis in the national territory of each country. Point 1 is located in the Pacific Ocean due west from the U.S.-Mexico common border and is the starting point in defining the Sharing Zone. The boundary of the Sharing Zone is then defined by plotting each geographic point in advancing numerical order in a clockwise direction. Each distance path between consecutive points is traversed by great circle arc.
