"The push-to-talk playing field just became a bit more crowded. After months of discussion and endless hinting by executives, Sprint PCS today launched its PCS Ready Link push-to-talk service. Sprint joins push-to-talk veteran Nextel Communications Inc. and newcomer Verizon Wireless, which launched its PTT service last August. Like Verizon Wireless, Sprint is using equipment from Motorola's Winphoria Division for its PCS Ready Link PTT solution."
