PROTOCOL
BETWEEN THE DEPARTMENT OF STATE

OF THE UNITED STATES OF AMERICA
AND THE SECRETAR�A DE COMUNICACIONES Y TRANSPORTES

OF THE UNITED MEXICAN STATES
CONCERNING THE ALLOTMENT AND USE OF THE 380-399.9 MHz BAND FOR FIXED AND MOBILE

TERRESTRIAL NON-BROADCASTING SERVICES
ALONG THE COMMON BORDER

 


This Protocol is being concluded on an interim basis pursuant to the Agreement Between the Government of the United States of America and the Government of the United Mexican States Concerning the Allocation and Use of Frequency Bands by Terrestrial Non-Broadcasting Radiocommunication Services Along the Common Border signed in Williamsburg, Virginia June 16, 1994, (herein referred to as the "Agreement").


ARTICLE I. Purposes

1. The purposes of this Protocol are:
a. To establish and adopt a plan for the equitable allotment on an interim basis of the frequency sub-bands in the 380-399.9 MHz band within the Sharing Zone defined in this Protocol; and

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.

ARTICLE II. Definitions


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 Secretar�a de Comunicaciones y Transportes of the United Mexican States (hereinafter Mexico).


2. The Sharing Zone is defined to include the border areas within the United States and Mexico and their respective territorial waters as set forth in Appendix I.


ARTICLE III. Restriction on Use of Mobile Satellite Service


Neither Administration shall introduce the mobile satellite service into the sub-bands allotted for the primary use of the other Party within the Sharing Zone defined herein.


ARTICLE IV. Conditions of Use

1. Within the Sharing Zone, the radio frequency sub-bands in the 380-399.9 MHz band shall be allotted for the primary use of each Administration in accordance with Appendix II. Each Administration shall ensure that new assignments made on or after the date that this Protocol enters into force are operated in such a way that the transmission bandwidth shall not exceed the primary frequency allotments in Appendix II.


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):

APPENDIX I
Areas Within Which the Frequencies Are to Be Protected

Areas Within Which the Frequencies Are to Be Protected


 


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.


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.
