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.”

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.

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.

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