The 600-page bill, approved after 17 hours of debate yesterday, will now pass to the lower house of Congress.
It creates regulations enacting a constitutional reform adopted in May 2013 and so far will mainly impact television giant Televisa and the telephone empire of billionaire Carlos Slim, which will each have to open space for competition.
The overhaul is a major piece of President Enrique Pena Nieto's structural reform agenda, which includes historic changes in the energy sector, tax collection and education.
Slim's Telmex controls 90 per cent of the landline phone market, and his Telcel company controls 70 per cent of the mobile phone sector.
Televisa, the biggest Spanish-language television company in the world, which airs content in 60 countries, controls 70 per cent of broadcast television and 60 per cent of the cable market in Mexico.
The Federal Telecommunications Institute (IFT), the new market regulator created under the constitutional reform, ordered both companies to make their infrastructure available to competitors.
Most of the debate was over whether the notion of "prevalence" applies only to the telecommunications and television industries, or also to related services.
The senate, following the position of Pena Nieto's government, decided to limit this notion of preponderance to within the major industries.
The subject sparked protest from Televisa and Slim's company, while opposition parties accuse the government of watering down the legislation's goal of opening up the sector to more competition.
