The nation’s two largest carriers added more connected devices last quarter than postpaid subscriptions, according to data released this morning by Chetan Sharma, a wireless analyst. Other than making you wonder what six-year-olds are toting cell phones, the data indicates that the Internet of things has clearly dawned, and with it, a new arena of competition. In his quarterly update, Sharma noted that wireless penetration in the U.S. reached 95 percent and surpassed 100 percent if one takes out children younger than five. While there are only 20 million connected devices out of 311.3 million subscriptions, the devices are where the growth is.
