Top message: Any updates on Sprint DC? by cellphonesaretools

Sure, all of the data & voice can and should be handled by the CDMA and upcoming LTE VOIP-based channels, but I do wonder if they couldn't have dedicated a comparatively small amount of bandwidth & computer in each tower to be hooked up like iDEN is (i.e. bypassing the PSTN) to provide genuine radio dispatch for the PTT calls. I know for a fact that Motorola has continued developing iDEN to be a more efficient system, and I'm sure Moto would have gladly worked with Sprint/Ericsson/whoever to integrate iDEN-like, radio-dispatch PTT into the new "Network Vision". You know, maybe just 3-5% of each tower's resources and a separate T1-type line that PTT would use.
Given that Nextel customers still represent roughly 15% of Sprint's customer base, dedicating a few percent of Network Vision to true radio-dispatch PTT is not too much to ask.
