LA JOLLA, Calif. -The Open Mobile Alliance has described as proprietary the Push-to-Talk standard announced by two competing vendor interests yesterday.
“They are not 3G products,” remarked Gaby Lenhart, chairman of the OMA PTT working group.
Nokia had said its products differ from those announced by other vendors like L.M. Ericsson, Siemens AG, Motorola Inc. and Sony Ericsson, which have recently conducted an interoperability test.
The standard will not be ready until the end of the year.
