Dead Zone Killer Makes GMC a High-Tech Leader

DETROIT Jan. 26, 2011

In an era where cars and trucks double as online data and information portals, General Motors has created a first-of-its-kind gigantic signal-testing facility to keep data, cellular and other signals active in areas where wireless signal strength is limited.  The Yukon Denali is one of the first vehicles to benefit from the technology, which looks like something out of a sci-fi movie.


The data is used to optimize satellite antenna design and placement on GMC and other GM vehicles.

"The ATS system lets us test the antenna systems on the GMC Yukon Denali in virtually every possible real-world condition," said Graham. "What would take other automakers days of testing can be done in minutes with this system."  

Graham confesses to dragging her family to remote parts of the country to spot test XM satellite radio and OnStar signals on GMC trucks and SUVs.

"They’ve been unwittingly pulled into my antenna obsession on several occasions while traveling."  

What’s her favorite arch?

GM’s antenna testing system is one of many behind-the-scenes facilities that make the 2011 GMC Yukon Denali a technology leader. Other technologies available on the 2011 GMC Yukon Denali, such as regenerative braking and active fuel management, are designed to provide efficiency, refinement and comfort without sacrificing professional grade capability.
