AT&T had a busy day Monday, from unveiling its Digital Home wireless monitoring service at an industry event to providing developers with details of new tools, including one that will allow a device user to port a mobile phone number across a range of devices. Also, AT&T Chief Technology Officer John Donovan detailed the carrier's plans to "densify" urban networks by substituting small cell sites for larger ones, a step aimed at preventing blocked calls and provide more reliable data speeds in crowded cities.
AT&T and Qualcomm introduced the "Internet of Everything" development platform based on a Qualcomm Gobi chipset designed to allow Java-based embedded devices to connect with the carrier's 3G network as well as to build industrial and health care apps.
