Verizon Wireless has confirmed that it will be rolling out an improved push-to-talk offering later this summer to compete with Sprint’s PTT services. Sprint recently launched QChat phones and services in several markets, including Colorado, Kansas, and Ohio. It will be expanding the availability of QChat over time. QChat permits standard CDMA-based phones to interact with iDEN phones and vice versa. Verizon will respond with the launch of new phones and an improved PTT service. It did not provide a time frame for the launch, nor did it say exactly what technology it will be using to improve it’s PTT service and make it competitive with Sprint’s QChat service.
