Qualcomm announced this week it has a program under way to develop Push to Talk (PTT) technology to run over Long Term Evolution (LTE) networks. As we all know, Sprint is migrating to a LTE network for it's 4G technology in Network Vision.

Qualcomm's current development schedule for LTE PTT is several years, with a commercial release in 2015 or 2016. In case you are wondering what PTT is, it's the walkie-talkie style telephones that have been offered from Nextel for years.

This seems like a natural migration path for Sprint's CDMA Direct Connect services which are IP based and largely dependent on network ping times for performance. The LTE network will have much improved and more consistent low ping times than their current CDMA network.

According to Qualcomm, not only are they targeting the commercial PTT sector, but they want to expand it to a large section of the smartphone market. If your smartphone had 4G PTT technology built into it, and Sprint allowed you to add it to your plan for no cost, would you use it? Sound off below...
