Wireless Carriers To Adopt New Real-Time Text Protocol By December 2017 (engadget.com)

An anonymous reader quotes a report from Engadget: The FCC is ready to adopt a proposal that'll bring a new protocol to wireless networks to help people with disabilities communicate. It's called real-time text (RTT) and will be a replacement for the aging teletypewriter devices that let users transmit text conversations over traditional phone lines. According to the FCC's statement, RTT will "allow Americans who are deaf, hard of hearing, speech disabled or deaf-blind to use the same wireless communications devices as their friends, relatives and colleagues, and more seamlessly integrate into tomorrow's communications networks." The big differentiator for RTT over current, commonly-used text-based messaging systems is that RTT messages are sent immediately as they're typed. The RTT technology will let text users communicate with people on voice-based phones and vice versa; it can also work easily in your standard smartphone, eliminating the need for specialized equipment. The proposal calls for RTT to roll out over wireless networks run by "larger carriers" by December of 2017.

    I gave up my TDD/TTY a few years ago, when I started using my own cell phone to send texts to family and friends, as well as my boss. I thought I had seen the last of the TDD/TTY when I did so, and now I'm interested in seeing how the new RTT works.

      I'm curious if we'll see new stand-alone TDD/TTY devices (that have a SIM slot instead of a phone jack on them), or perhaps wireless carriers will just do a web-based gateway service instead (log into your account on your carrier's website, enter a destination number, and once the connection is made type away in the input area).

      I'm sure we will. Because that way the manufacturers can rely on FDA regulations to keep the market to themselves and jack up prices.

      Like the touch pad speech generating devices used by people with ALS which, in theory, could be replaced by a cheap tablet app. But nope. Can't do that because the moment it becomes an assisitive device, the manufacturer has to jump through FDA approval hoops.

      Yeah, that works for most things.

      However, government communications, finance (minor things can be done online; big transactions still require a phone call with security checks), and that kind of thing need something extra.

  5. If your backbone is 64K dial up by raymorris · · Score: 1

    If you're shared medium, your office backbone, is a dial up connection then yes, small messages are inefficient.

    In the US, dozens of packets from a user using this protocol are nothing compared to the billions of packets used by an HD video stream.

    The other way around is much bigger problem. High bandwidth connections with lots of traffic means a lot of big queues. Queues murder latency and jitter. Telcos can and do use a lot of processing to try to speed the few latency-sensitive packets through the sea of data, but that's not free. Wireless carriers have to be good at doing so because 150ms or 250ms of latency is quite noticeable on a voice call.

      No, those are the equivalent of IRC. You type a line, and it isn't sent until you hit the enter (or send) key.

      This is more like the old Unix talk program. Every key you type gets sent as you type it. The recipient can watch the other person type, including correcting mistakes. It doesn't have the "I'll get to it when I have time" nature of SMS, email, etc. where you can just ignore an incoming message and reply to it later. It's more interactive, and real-time - like a phone call. Which is why it's of interest for deaf people. I would've thought the old teletype protocol could've been easily incorporated into to an app, but I guess not (cell phone voice transmissions are sent a different way than data, and this sort of device has to use the voice channel to maintain compatibility with landline units which may be in a location without Internet).

      Funny, my company spent (several years ago when we did smartphones) a lot of time and effort getting TDD/TTY devices working with them. Not because we wanted to, but it was a carrier requirement for our customers. Admittedly, it was basically a device that hooked into the headset jack of the phone and transmitted tones over it. Now, the network doesn't transmit the tones directly I'm led to believe - the cellular modem was put into TDD/TTY mode and we fed the audio directly to it where it's decoded and sent over the network as data instead of voice packets.

      Of course, these days one wonders why you can't have an app for that, but our smartphones had, by our customers request, TDD/TTY support. Heck, until the customers asked, we didn't even know it was supported.
