Cellular Phone Forum / Providers / Nextel / January 2004Nextel PTT vs PoC
I'd like to understand more about the technical differences between how Nextel PTT operates and how push to talk over cellular (PoC) will work. I have read a lot of older posts that are sort of related to this, but I'm seeking greater clarity. Any help appreciated!

Kathy Heh, given the experiences others have had with Verizon Push-To-Talk, I parsed PoC as "Piece of Crap." <g>  SignatureJustThe.net Internet & New Media Services, Apple Valley, CA Steven J.

I would have to agree there. From a user's standpoint, soon to be 'former' user, VZW PTT simply SUCKS!!!!! Sensor Man wrote: > * > Nextel is basically a two-way radio with cell service added.

If you ever used > voice-over-internet it's the same concept. * verizon also does not search over the network constantly, only ever few minutes, where nextel is searching for the closest towe continuously. basically, when a ptt (by verizon) is initiated it mus search the network and will "dial-in" as a standard cellular cal (unlike nextel) and will then get transferred to the other user. ther are more technical definitions too...i'll look them up because i explains much better than i do!: - rdmille > Sensor Man wrote: > [quoted text clipped - 22 lines] > ------------------------------------------------------------------------ > http://cellphoneforums.netView this thread: http://cellphoneforums.net/t106607.html Very interesting, I wonder how does Sprint's (crap) ptt or Alltel's new ptt work? are they also POC as I read somewhere months ago ...I believe it was T-Mobile with one of the Nokia's was going to implement the ptt but over gprs. @(none) wrote: > *rdmiller wrote: > > Sensor Man wrote: [quoted text clipped - 46 lines] > ptt > but over gprs. - mmdstec Kathy wrote: > *I'd like to understand more about the technical differences between > how Nextel PTT operates and how push to talk over cellular (PoC > will > work.

Kath > * iDEN allocates certain channels at each EBTS for dispatc calling(half-duplex). These channels are allocated at 6:1. Th interconnect channels are allocated at 3:1, or with SR10.5 and whe activated, 6:1. 1. MS initiates a call. 2. calls arrives at the EBTS. 3. ISC discriminates what type of call it is. 4. we will assume it is a dispatch call.frame relay. 5. T-1 facilities to the DACS at the MSO. 6. call routes to the MPS and then to the DAP which includes the HL and the VLR. 7. If it is a group call the call routes from the MPS to the PD and o the APD. The DAP( dispatch application processor) assigns the signaling an routing paths for dispatch and packet data. CDMA operators have to us VOIP protocols like Winphoria( which interesting enough is owned b Motorola - mmdstec It doesnt make sense because people just post what they think, not actually how it works. -- mmdstech heh! very nice...Nextel.Done. | -- rdmiller > I'd like to understand more about the technical differences between > how Nextel PTT operates and how push to talk over cellular (PoC) will > work.

That's why it's PTT is very fast and efficient. VZW sends it's PTT voice data in packets over the cell network, which is why there are longer delays in the talking. The busier the network, the longer the pauses can be between talk and listen. If you ever used voice-over-internet it's the same concept. >> I'd like to understand more about the technical differences between >> how Nextel PTT operates and how push to talk over cellular (PoC) will [quoted text clipped - 8 lines] >the pauses can be between talk and listen. If you ever used >voice-over-internet it's the same concept. yep, vzw and sprint use VoIP for ptt. alltel uses kodiak or somethng like that. and Iden is something about switch routing.
