Internet-connected cars and other everyday products have become the fastest-growing part of the U.S. wireless industry, adding more links than mobile phones and tablets combined in the second quarter.
AT&T Inc. dominated revenue in connected devices, with the company connecting cars to its network at twice the pace of tablets, analyst Chetan Sharma said in his quarterly wireless industry report. AT&T should reach 10 million connected car subscriptions soon, he estimated. Verizon Communications Inc. is actively adding connected devices as well.
For carriers, the so-called Internet of Things -- a world in which everything from garage doors to cars to light bulbs connect to the web -- has become a major source of revenue growth at a time when phone-related business has slackened.
