AT&T ($T) will experiment with digital-only telephone service in towns in Florida and Alabama in a project that accommodates medical device-related data and services. Bloomberg reported that the option would be muscular enough to carry data required by alarm systems and medical devices, something that could help expand the accessibility and use of mobile medical device apps and related services. AT&T wants to end the use of traditional copper wire networks by 2020, Bloomberg noted. They're mostly there already. More than 70% of residential customers in the phone company's 22-state service area have already moved away from traditional wired service, AT&T has said, according to the article, which notes that the phone company wants to end rules that stop it from dismantling legacy systems.
