  The U.S. Department of State has posted a news item entitled, "Amendment 
to the U.S-Mexico Bilateral Agreement for the 700 MHz Band to Allow for 
the Timely Deployment of Fourth Generation (4G) Wireless Broadband Service."  
The story reads as follows:

  "On July 28, 2011, the FCC and the Mexican Ministry of Communications 
and Transportation concluded an exchange of letters to amend the 2006 
Protocol for the 698-806 MHz band to increase the power limitations and 
facilitate increases in parameters when counterpart operators across the 
border from each other do not exist.  The changes were necessary to 
accommodate the advanced technologies employed for 4G service.  The 
amendment became effective on July 28, 2011 and applies to both sides 
of the entire common border area."
