Motorola introduced an IMS-based solution that extends Push-To-Talk connectivity across and between GPRS, CDMA2000 1X, and WiFi networks. This is a network-based solution, aligned with Open Mobile Alliance (OMA) standards, that does not require modification to standards-based Push-To-Talk over Cellular (PoC) clients.
Motorola said its Cross-Technology PoC solution would also be compatible with future Data Rate for Global Evolution (EDGE), High Speed Packet Downlink Access (HSDPA), Wideband CDMA/Universal Mobile Telecommunications System (W-CDMA/UMTS), and 802.16 “WiMAX” technologies. It is available for technical trials with select customers. http://www.motorola.com
