DETROIT — AT&T Wednesday announced the expansion of its mobile Internet network by enhancing 10 cell sites along I-69, from Calhoun County south through Branch County to the Indiana state line, that provide coverage for area residents and businesses.
The network enhancements extend access for advanced mobile services, devices and feature-rich audio and video content to customers who travel, live or work in these areas.
From 2009 through 2011, AT&T invested more than $1.5 billion in its wireless and wireline networks in Michigan.
AT&T’s mobile Internet network is based on the 3rd Generation Partnership Project family of technologies that includes GSM and UMTS, the most widely used wireless network platforms in the world. AT&T has the broadest international coverage of any U.S. wireless provider, providing access to voice service in more than 225 countries and data service in more than 200 countries. AT&T also offers voice and data roaming coverage on more than 135 major cruise ships, as well as mobile Internet services in more than 130 countries.
AT&T also operates the nation’s largest Wi-Fi network with more than 30,000 hotspots in the U.S. and provides access to nearly 225,000 hotspots globally through roaming agreements. Most AT&T smartphone customers get access to our entire national Wi-Fi network at no additional cost, and Wi-Fi usage doesn’t count against customers’ monthly wireless data plans.
