iDEN vs OpenMobileAlliance technology

Archived from groups: alt.cellular.nextel (More info?)

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

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
