American Tower Corp.’s growth strategy is based on a premise that’s hard to dispute. The Boston company that placed fourth on the 2013 Globe 100 list believes consumer demand for mobile communication and entertainment is only going to grow stronger in the future. American Tower, which operates communications cites around the world, saw that demand propel profits by 60 percent to $637 million last year. Chief executive James Taiclet believes installation of fourth-generation wireless technology will require more towers and additional communication devices on existing cell sites. Since 2007, American Tower has nearly doubled revenues and manages more than twice as many towers. Now the company has a new goal in mind — to double in size again over the next five to six years.
