Sprint 4G Rollout Updates

Thursday, February 23, 2012 - 1:01 PM MST

 

Sprint announced yesterday that in recent testing conducted in 17 markets, that their new CDMA-based Sprint Direct Connect met or exceeded all measurements. Sprint Direct Connect, or SDC, is the successor push-to-talk network that Sprint is implementing to replace its aging iDEN network it inherited from its merger with Nextel.

 

This come on the heels of recent developments of how the Nextel iDEN PTT sites are currently being reduced in some areas, in preparation of next years shut down. Sprint Network Senior VP Bob Azzi said of the results, "(this is) conclusive validation of Sprint's sustained push-to-talk leadership."

 

Sprint Direct Connect PTT will offer a much expanded footprint over the current Nextel iDEN legacy PTT network. Most of the expansion is due to the ability of the SDC devices being able to roam on other CDMA 3G networks. This roaming ability is expected to start opening up to current Sprint Direct Connect customers in the next few months.

 

The data experience for SDC customers is being touted as much improved over the 2G like speeds endured on Nextel's iDEN. Being CDMA based, the EVDO network will be seen as a much improved data solution for Sprint's PTT customers. Although, in some areas in the short term, Sprint's EVDO will perform at 2G like speeds. No surprise that Sprint didn't mention this point. However, the 3G EVDO data experience will demonstrably improve through Network Vision upgrades.

I wonder if Sprint is going to allow 3G roaming on SDC devices onto VZW & others until they get their own data speeds together, at least it makes SDC more useful.

We actually use the SDC devices here at work. Half of our staff are on the old Nextel PTT devices, and the other half are using the Motorola SDC units.

How is it working so far?

Are you in a Sprint coverage area? Any 3G? How good is it?

It was a fail for my buddy. He's been using Nextel for years for work. Decent Nextel coverage in his home. Sprint CDMA switches back and forth from roaming to native all the time. He was telling me about some jobs he goes to there is no Sprint CDMA coverage but his Nextel has full coverage and works fine. His only option is AT&T at this point.

It just doesn't work when you have such a huge difference between coverage (yes I know it's from 2010 but it hasn't changed in 5 or 6 years maybe more).

Our coverage is about the same. The devices could use some work though. Sometimes it would take a second or two for the SDC devices to connect to the network and start transmitting. There was a recent update that helped out tremendously though

 

The 3G on them is horrible, at least it was when they first got the units, which was about a month ago or so. I haven't had a chance to test them. They are both using the Motorola Titanium

The titanium is an iDen phone. The Motorola Admiral is CDMA PTT.

We have a couple of the new Admirals since they were released in Oct. They work nice if you never loose sprint coverage. Once you roam SDC will not work anymore even after returning to sprint coverage. You have to reboot phone to use SDC again. Sprint did not plan this very well. Even though Nextel had limited coverage at least when you got back to a Nextel area you could use SDC without having to reboot all the time. The phones are nice but can only make use of DC about 60% as much as with the old Nextel phones we had. A new PRL helped a little so sometimes SDC will return after a few minutes but still need a lot of reboots. I tried waiting over night and still no SDC

Two separate networks so coverage depends on where you are.

 

Nextel DC Coverage:

Sprint DC Coverage

However, after Network Vision, the coverage should be terrific.

 

And yes, there is a known issue if the Admiral drops to 1XRTT or roaming it will not go back to SDC until rebooted or, I have heard, if you toggle Airplane mode.

Ahh yeah, maybe they are the admirals. I haven't looked at them since they first got em. Maybe I'll ask to check em out to see if things have improved. I'm still on an old Nextel.

Anyone have any idea if they are going to fix this Admiral defect or am I stuck having to reboot my phone several times a day for two years. I did try toggling airplane mode once but did not turn SDC back on only reboot seems to fix
