Great questions. CDMA uses a spec where voice and data are not available at the same time. This means if you're on a voice call you can't pull down wb pages or mail etc. This is a problem for the deaf because they use call captioning services. What these do is provide a just about near real time written transcript of what's being said by the far end. I believe voice recognition is used for this and the output text is displayed on a web type interface that the deaf user views while on the phone. As you know many if not most deaf people can speak very well it's just hearing the far end that's the challenge. On GSM / UMTS devices you can easily see the web content and talk at the same time bcause that facility is provided as part of the protocol, CDMA this is not the case.
Hope that clears it up a little. On Jan 12, 2011, at 11:44 PM, Chris Moore wrote: > Sorry for coming across a bit thick here.
