In their push to introduce a CDMA equivalent to Nextel’s iDEN-based Push-To-Talk feature, Sprint has announced the first cross-network walkie-talkie call last week. The call connected a CDMA and iDEN phone, and represents a major advancement in Sprint’s efforts to integrate the walkie-talkie feature on the CDMA Rev. A network. The tricky part is emulating the functionality of a feature that was built into the iDEN network (from the ground up) on Sprint’s mobile broadband network.
If all goes as planned, and this latest test is a good sign, Sprint will be launching their new mobile broadband service in 2008. Once complete, CDMA and iDEN users alike will be able to get their “chirp” on.
