With AT&T’s arrival in the Mexican wireless marketplace with its purchase of Iusacell and Nextel, América Móvil is responding with plans to build a new state-of-the-art $50 billion fiber-to-the-home network for Mexican consumers.

According to El Economista, América Móvil has a five-year plan to construct a 311,000 mile fiber network that will offer phone, broadband, and television service. The move comes in response to media reports AT&T is exploring delivering a video package over its acquired wireless networks within the next two years. The network will support broadband speeds that are faster than what most Americans along the border with Mexico can receive from AT&T and CenturyLink’s prevalent DSL services.

In comparison, U.S. phone companies like Verizon have stopped expanding its FiOS fiber to the home network and AT&T largely relies on a less-capable hybrid fiber/copper network for its U-verse service.

Competition in Mexico has forced providers to upgrade their networks to compete for customers while those in the United States tend to match each other’s prices or advocate for industry consolidation to maximize revenue and keep their costs as low as possible.

América Móvil’s broadband service Infinitum Telmex has already attracted 22.3 million broadband customers — a number likely to rise once it can enhance its online video streaming service Clarovideo.
