Hi John,
It was with the QCOM and Gilder posts in mind that I sculpted my statement. My point was that future IP on cellular would involve the "inclusion of voice and data" in addition to the adminstrative capabilities allowed through IP, as the case has been up until now, or recently.
>>IP in cellular is not new. CDMA from QCOM has had a full IP stack since 1991. See QCOM thread msgs 20547 from George Gilder and 20555 from engineer for info on full IP stack in CDMA and new pdQ.<<
In contrast, what has been in place using their (QCOM's) TCP/IP stack up until now (since '91, as you correctly noted) has been the ability to perform administrative tasks over wireless links using IP. This did not, however, to the best of my knowledge, include voice and data, or end user payload transport.
VoIP, in the true networked sense of being able to encode/decode and transport voice and data, has only been with us in crude form since the mid-Nineties. It's only been tuned, and to some degree perfected (cough!), recently, to the point where we are seeing the beginnings of concensus as to how to manage it in a commercially viable way.
If I am mistaken about any of this, I'd gladly stand corrected.
