MEXICO CITY, Dec 18 (Reuters) - AT&T Inc and billionaire Carlos Slim's America Movil are interested in an auction of 80 MHz of wireless spectrum in February, the Federal Telecommunications Institute (IFT) said in a statement on Friday.
The IFT said the companies would need to file documents in January ahead of the auction on Feb. 15.
Since declaring Slim's America Movil dominant in the sector last year, the IFT has been introducing stricter measures designed to boost access. America Movil operates around 70 percent of Mexico's mobile and fixed lines. (Reporting by Michael O'Boyle; Editing by Lisa Shumaker)
