Tired of abysmal sound quality when yapping via PTT? Are your chirps not leading to responses in a timely fashion? Never fear, as Motorola is all over it. For better or worse (though probably better), Moto has released its next-generation push-to-talk over cellular (PoC) solution, which is optimized for CDMA 1x networks with EV-DO Rev. A data capability. According to the official verbiage, the new solution leverages the zippy protocol to provide "low call set-up time latency and improved quality of service (QoS)." Rev. A chirping -- who woulda thunk it?
