C-level officials are the public face of companies, but little-known executives are often powerful players behind the scenes. They are the ones doing the heavy lifting necessary to grow or create business units, take risks and overcome challenges and corporate bureaucracy to deliver results. In our annual feature, FierceWireless acknowledges achievements of the wireless industry's rising stars, whose efforts often go unheralded. Some are industry veterans who have been asked to take on new roles and responsibilities, others are refurbishing business units and driving new strategies while others are working to push networks at carriers to the next level. We think that the executives we have chosen this year as rising stars in the wireless industry are working on projects or leading business units that are likely to have large-scale impacts on their companies in the years ahead.
