MEXICO CITY, March 6 (Reuters) - Mexico's telecoms regulator said on Thursday it would introduce measures to boost competition in a market dominated by billionaire Carlos Slim's phone giant America Movil.
The Federal Telecommunications Institute (IFT) said it had determined who is dominant, or has an oversized market share, in the telecoms and broadcast sectors.
It did not name the companies but America Movil controls around 80 percent of Mexico's fixed-line business via its Telmex unit and about 70 percent of the mobile sector through its Telcel subsidiary.
In December, America Movil and broadcaster Televisa said the regulator had told them it was determining whether they are dominant players in their industries.
The IFT said it had approved measures that include the unbundling of the local loop for the dominant telecoms player, which would give increased network access to competitors.
The regulator said it was in the process of notifying the companies concerned. A spokesman for America Movil said the company had yet to be notified.
The dominance ruling is part of wider reforms of the telecommunications and broadcast industries approved by the government which have lifted expectations that Mexico might finally tackle the extraordinary power enjoyed by a select few companies in Latin America's second largest economy.
The reforms will allow the regulator to apply tougher rules in an effort to even the playing field for smaller competitors.
Televisa, the world's largest Spanish-language content producer, has more than 60 percent of the TV market, leading many Mexicans to complain that it exerts too much political influence.
