    Hi,
    I've a specific question to compare the Push to Talk (PTT) service
    developed by Open Mobile Alliance (http://www.openmobilealliance.org)
    with iDEN technology.

    In a PTT half-duplex call involving 3 users (UserA talking; UserB &
    User C are listening and are within the same cell), there will be a
    seperate radio channel to carry voice packetes to UserB and UserC.

    When we take the same scenario as mentioned in the previous paragraph
    for an iDEN network, will there be a seperate radio channel to UserB &
    UserC?

    -Regards
    Vinoth

    If I read it right I think you can in the group call this way, we use it in
    our Nextel we got 6 user's we all got the same fleet number so we all can
    talk to whole fleet. now if I need to keep it within 3 user's I program the
    sub fleet number to just those three phone and just those three got there
    own channel. but we try not to use group call feature to much because it can
    get little expensive at time. my explanation might be wrong in term wise but
    I hope I got the idea right

    iDEN: You would use 3 slots (1/2 a 6:1 channel) for a 3 person DC
    conversation on the same cell site. When users are on different cells
    I don't know if the packets are multicast over the back haul or not.

    Openmobile: I have no idea
