AT&T made an announcement, saying that it is prepared to respond quickly to Tropical Storm Bonnie, with an "arsenal of disaster response equipment and personnel."

"The Texas coast has been tested by inclement weather and hurricanes in the past and AT&T has always been quick to respond and restore service to impacted communities," said Chris Penrose, vice president and general manager for AT&T in South Texas. "Our customers rely on us to be prepared and keep them connected during emergencies, and we are committed to fulfilling those needs."

AT&T lists the following precautions it has taken:

• Adding capacity to the wireless network to accommodate increased call volume.
• Testing the high-capacity backup batteries located at every cell site.
• Distributing extended battery life and portable generators, and maintaining existing fixed generators.
• Topping off generators with fuel at cell sites and central and field-level switching facilities.
• Using natural gas in some of the permanent generators to eliminate the need to refuel.
• Staging generators in safe locations for their immediate deployment once a storm has passed.

The company has invested more than $500 million in its Network Disaster Recovery (NDR) capabilities, which includes over 300 technology and equipment trailers. The company says it invested $145 million in recovery and restoration efforts related to the 2008 hurricanes.
