Goodbye iDEN

This looks like the unofficial, eventual end of the iDEN network to me. Anyone else concur?

Yeah, I concur. I don't really understand the different between iden push to talk, what AT&T offers they're push to talk, or Qchat, they all seem the same to me.

iDEN PTT- Is a digital, trunked radio system. A switch based integrated half-duplex system that allows for instant communication at the push of a button.

QChat- An net based PTT system that uses broadband to send and receive voice calls at the push of a button. Latency of initial call setup is reportedly slightly slower than that of iDEN.

AT&T PTT- Uses Kodiak's Push-over-cellular technology to imitate a two-way radio conversation. This system uses an actual cellular voice channel to send & receive communications. Latency on initial call setup is extremely slow, similar to the amount of time needed to send a text message.

I don't see any replacements to my Nextel Blackberry 7100i yet (work paid), and I've only had it since the summer.

in english?

Nextel is like using a walkie talkie you buy in the store. Instant connection with a push. ATT you push wait wait wait and then connect and still the voice is slow getting back and forth. Have you ever used nextel? I have and sprint CDMA one and there is no comparison. Sprints was garbled at times as it uses the 1xrtt data network to transmit. Really have to see it in real life and you will see in a instant (no pun intended) what the difference is!

There is a big difference with each push to talk solution. Mainly it has to deal with latency on the intra calling and set up. After that, it has to deal with whether it is on a great network voice and data wise. If there are the right circumstances with a great data network that delivers high-speed data and a push to talk network that delivers very good intra calling and set up calling latency, it will be a very big winner to the business and enterprise customers, because you can do whatever you want with that solution. They aren’t the same at all. Go try a Nextel PTT and try an AT&T one: much difference. Nextel wins on the intra calling and set up calling but AT&T wins on the data speeds and in some areas network, although, PTT can st...

Qchat is Sprint's solution on the FCC'c rule regarding the movement of the iden network. I think the deadline that the FCC gave Sprint to move the iden network is on june 2008. It is also the reason why Sprint has introduced the hybrid phones so that they can switch those direct connect customers to the sprint network.

That is actually wrong. Sprint well Nextel wanted to do something that will prepare for the merger with Sprint’s CDMA network which is why Nextel, Motorola, and Qualcomm developed Qchat (well I guess now its Broadcom’s as they won a suit). The FCC Consensus plan in which you are referring to does not say that Nextel has to be off the IDEN network at all it just states that some spectrum will be given back in exchange for 10mhz of 1.9ghz and some spectrum back but in a contiguous band. FCC said they must configure, retune, and finish the tuning of the spectrum bands by a certain date cept Sprint is asking the FCC for many extensions and an emergency issue due to capacity issues. (On a side note; I was away for some time and when I c...

Good to see you back. 🙂

Beside that, a Hybrid phone wouldn't solve a Nextel user's dilemma if the government was mandating a 2008 shut-off, since the PTT portion of a Powersource phone uses iDEN for that purpose.

Yea I realized that this is very severe and FCC does have a right to impose fines and other sorts if the promises are not met but this is to the extreme to threaten a shutdown. Nextel did this to please the FCC so I think FCC should give it to some leeway. Regardless, it will not happen because 20 million+ will be affected including government and enterprise customers. Remember the threaten of the RIMM situation and injunction, well it is the same thing and it did not happen there so it will not happen here. Of course, they are separate matters but with the end, result should be the same especially when millions of people will be affected by this. Threatening a network shutdown is not in the interest of anyone. FCC actually threatened to jus...

it will very exciting to use these phones. I finally had to switch over to sprint because nextel in my area was just to unreliable. I put my dad on one of the PowerSource phones, as he refuses to do without the direct connect. Finally i'll be able to get all the ppl on nextel direct connect with a sprint phone 🤣
