In pictures: Inside the IoT and M2M innovations at AT&T's Texas-based foundry

At an unassuming office park a short drive from Dallas, a group of AT&T (NYSE: T) engineers have what many might consider the best jobs at AT&T--working at the company's Plano-based Foundry. This innovation center, which was opened in March 2011 and expanded to include M2M operations in 2014, is one of four foundries the company established globally to serve as a test-bed for new technologies and give AT&T an opportunity to work with partners and startups to accelerate innovation in areas like the Internet of Things and M2M. During a recent tour of the facility, Craig Lee, AT&T's M2M Foundry director, said that the group works on about 10 projects at one time. Unlike a typical product, however, these projects move quickly from concept to reality--often in a time frame of 18 months or less. To get a sense of the innovations on hand at the foundry, from in-stadium Wi-Fi to connected refrigerators, check out this slideshow.
