Pangean Technologies last month launched Y-Talk, a session initiation protocol-based software application that brings push-to-talk functionality to any Windows PDA, explains Mobile Radio Technology.
The application is targeted primarily at campus environments in the hospital, warehouse, and retail sectors and currently is available on Symbol Technologies MC50 and MC70 enterprise digital assistants.
Y-Talk’s voice-over-Wi-Fi technology, was first was developed for PCs about two years ago and allows them to create an ongoing talk group.
“They’re always there, as long as you’re logged onto the system,” he said. “You don’t have to set up a conference, or anything like that,” said Pangean CEO Tarun Kapoor.
Pangean’s engineers encountered a few challenges along the way, Kapoor said.
Complicating matters, according to Kapoor, is that mobile devices require a unique installer for every platform and device being targeted. “It’s a configuration-management nightmare just making sure you keep up with all of these things.”
“With some PDAs that are operating on Windows, the battery dies after four to five hours,” Kapoor said. “If you’re using push-to-talk all the time, you might get a very low battery after just a couple of hours.”
“Most existing wireless LANs in enterprises are not optimized for voice in the traditional sense … of a circuit-switched call,” Jackson said. “So these networks require considerable optimization and, in many cases, wholesale equipment upgrades to handle the resource intensity of multiple simultaneous data users.”
