Push to Talk and some facts
PTT over iDEN (Nextel)
Average call set-up 0.92 seconds
Mouth-to-ear Latency 0.58 seconds
PTT over 1xRTT
Average call set-up 4.3-6.3 seconds
Mouth-to-ear Latency 1.1 - 1.5 seconds
PTT over GPRS (PoC Standard)
Average call set-up 1-2 seconds
Mouth-to-ear Latency 1-3 seconds
PTT over EV-DO Rev. A
Average call set-up
well anyway for PTT over EV-DO Rev. A
the average call set up is= less then 1 second
the mouth to ear latency is= under .5 seconds.
Nextel you are the master of deception. I like how all the things you put on the first post, Nextel's beat all them out. But you included the winner on the second post, so maybe no one will look there.
Great job.
With the introduction of these various 3-3.5G mobile technologies, wouldn't it be to the advantage of U.S. wireless carriers to explore a PoC(OMA) standard for PTT? I could imagine increased RPLs (revenue per line) if an ATT customer to PTT a Nextel/Sprint or VZW customer? Everyone makes money by charging extra for PTT...right???
When you have customers from different carriers having what we call interoperability, it can be done but it is challenging. Moreover, Sprint would never let anyone use its Qchat solution or else they would not have made that solution proprietary. It would not be in their interest to share. They could but it would not be wise.
