A new infographic is providing a realistic look at the demand for mobile connectivity and the limited space on the airwaves that's available to accommodate consumers.

Called “Growing Demand for Wireless Spectrum,” the infographic shows that the U.S. government has assigned less than 16 percent of the airwaves between 400 MHz and 3 GHz for commercial wireless broadband services. In contrast, the remaining spectrum — nearly 85 percent — is occupied mostly by TV broadcasters and government agencies.

“Rapidly growing adoption and limited spectrum resources is a losing combination for the 330 million wireless connections used by American consumers,” said Jonathan Spalter, chairman of Mobile Future, the coalition that released the infographic, in a statement. “With consumers already starting to see the affects from near capacity mobile networks, it is critical that government act swiftly and responsibly to free up more spectrum to help keep pace with exploding consumer demand for wireless connectivity.”

According to Mobile Future, 3 billion networked devices are expected in the U.S. by 2016, which translates to more than nine devices for every person. Cisco also predicts that U.S. mobile data traffic will grow 16 fold by 2016. Despite the FCC estimating that mobile demand will exceed available spectrum by 2013, spectrum allocation has not kept up accordingly.
