FCC grants waiver to AT&T to proceed with Wi-Fi calling

FCC grants waiver to AT&T to proceed with Wi-Fi calling
Late last week, we shared news about AT&T’s consternation over Sprint and T-Mobile rolling forward with Wi-Fi calling despite not receiving a waiver from the FCC.

At the heart of the issue is compatibility of non-hearing customers that use “text telephony” (teletypwriters), which does not reliably work on Wi-Fi based communications. AT&T had been waiting for a response to a request to implement Wi-Fi calling in support of an alternative protocol for the deaf, called RTT (real-time text), which is under development.

AT&T had been planning to launch Wi-Fi calling in September, but the nod from the FCC was not forthcoming, pushing the carrier’s plans back to some undetermined time. Yesterday, the FCC gave AT&T the needed waiver so that it does not have to guarantee TTY transmissions over Wi-Fi calls.

According to the FCC, there are “major technical barriers” that get in the way of reliable transmissions of TTY over IP networks. This is as much a limitation of TTY which was invented in the 1960s. However, current regulations require that phone companies and wireless carriers support TTY, hence the need for a waiver.

AT&T is pushing the FCC to levy some type of enforcement action against T-Mobile and Sprint since they have been operating outside the regulations for “quite some time.”

Got that on Three Mobile about a year ago but doesn't work on rooted phones so have to do without.

Had it on TMO for a while now. Nice back up they give you. If wifi is around you can call from anywhere. Gotta love that.

Awesome! However it'll probably only be rolled out to stupid iPhones. I highly doubt it'll work with the Nexus 6P I'm planning on getting.
