Mexico's telecom industry grew 11.9 percent in the first quarter of 2012 compared to the same period last year due mainly to strong performance by the satellite TV, mobile telephony and long distance segments, the Federal Telecommunications Commission, or Cofetel, said.

The telecom industry's growth was much more robust than that of the economy as a whole, which expanded by 4.6 percent in the first quarter, Cofetel said in a statement.

The strong quarter was due in part to market changes that bolstered competition and to various strategic alliances forged among telecom firms.

Technological developments that have made fixed and mobile broadband services the "main drivers of growth" also were a contributing factor, the regulator said.

The most dynamic segment between January and March was satellite TV, which grew 26.9 percent relative to the first three months of 2011, followed by international long-distance telephony, up 26.6 percent, and mobile telephony, which climbed 15.8 percent.

The number of mobile broadband subscribers rose from 4.1 million at the end of March 2011 to 8.7 million at the close of the same month of 2012, Cofetel said.

Landline service continued to cede ground to mobile services in the areas of voice and data transmission, with the number of fixed-line subscribers falling to 19.7 million at the close of March 2012, down 0.3 percent from the end of the first quarter of 2011.
