Is a tower that connects eHRPD already upgraded?


Recommended Posts

To quote Robert from another topic,

Sprint installs eHRPD as a software upgrade over the EVDO network in an area before LTE is deployed. It must be complete on each LTE site and every site surrounding a live LTE site, to allow for the proper handoff between EVDO and LTE.

 

So Sprint typically is upgrading all the sites to eHRPD well in advance of LTE deployment. Every market that has active NV deployment already has eHRPD largely deployed. And some even that will not get LTE until 2013 are already reporting some eHRPD, most likely caused by which LTE core they are connected to coming live.

 

eHRPD is EVDO that runs through the LTE core, so it can maintain one IP address as it handsoff between LTE and 3G. It is possible that eHRPD will be faster at times, if the LTE core is less busy than the EVDO data switch. But when using the same backhaul, EVDO and eHRPD should be similar speeds.

 

So connecting to eHRPD doesn't necessarily mean anything about the tower to which you are connecting.

Interesting then that the Boston area is getting LTE towers going live, but I still haven't seen any eHRPD connections anywhere in Massachusetts. Only time i've gotten an eHRPD signal is in the Baltimore airport.

But now that Sprint is actively blocking LTE connections, eHRPD availability is less important. It will need to be up on every site and every site adjacent to any unblocked LTE site in order for the handoffs to occur as designed.

 

In cases where Sprint does not have eHRPD ready to be used around completed LTE sites, I expect them to continue blocking access to that LTE site...even on launched markets.

I live on the CT/MA border does that mean they should set my tower(CT) up for eHRPD so i can switch to LTE when you go into MA.

 

That's a good question. You would think so. I'm not sure how they will handle market boundaries. My guess is if the CT site is on the same exact 4G core as the site across the border in MA, then I believe they will.

how far in advanced do they do eHRPD and what is it software/hardware. like ahecht said it's not in the Boston market yet i keep checking.

 

There is no definite timelines in advance that eHRPD gets operational in advance of LTE. I just don't think they will allow LTE sites to go live without eHRPD live around it. Especially since LTE will start out as islands. They want customers to be able to Anne off seamlessly between 3G and LTE.

I have visited a couple of the MA LTE sites and have not found either LTE or ehrpd.

What are you using to try to connect to LTE or eHRPD? The E4GT is not capable of either connection...

What are you using to detect eHRPD vs CDMA? Thanks.

 

The Netmonitor app on Android works pretty well; you can also look under Settings -> About phone -> Network (at least on the Evo 4G LTE, although I think that's the standard place on all ICS phones).

He assumed you still have a E4GT, because that is what is listed in your profile. You should update your device when you get a chance.

The app is called "network signal info" by kaibits software.

 

Yeah, another of the class of apps that I don't like for privacy reasons, even the so-called "Pro" version. I realize that some people don't share my opinion, but I won't install such an app and widget.

May I ask what's wrong with the app?

Yep..nice looking app but horrible permissions.

Installing the app grants it permissions that could enable reading your phone number and those you connect to, as well as your location, and report them somewhere via an Internet connection over which you have no control. And if the widget is installed, then it runs full time as a service. I choose not to do that, although it is increasingly common as a business model to barter one's private details in exchange for the use of a "free" app. But even the paid "Pro" version has all those permissions.

    • The Kendall/Kerr/Gillespie PCS swap is a very nice win-win for AT&T and T-Mobile. Means both of them will have a 20x20 PCS channel, though in exchange T-Mobile goes from 10x10 to 5x5 on one of their spectrum blocks. I figure AT&T will start running n2 DSS on that channel, as they have enough customers in those areas to need the capacity, while T-Mobile will probably just run B2 LTE, as once Auction 108 finally clears they'll have plenty of n41 to play with. Guessing we'll see the non-G-block 5x5 slice running n25, but it would get aggregated with n71 rather than n41 I figure as n71 will remain 20x20 there until the STA goes away (and maybe after that, as if T-Mobile gets 700 MHz as the result of VZW buying West Central Wireless's spectrum there's no reason to run LTE in 600). Which makes me think that the next move is T-Mobile trading 700A for the 5x5 of orphaned PCS (E block) to VZW once the WCW transaction closes, as that would give VZW 20x20 PCS in the area, and would give T-Mobile 700 MHz in an area where they have none. Then VZW can either trade 700B to T-Mobile as well in exchange for the AWS I block in those areas (gives T-Mobile 10x10 B12, gives VZW 15x15 B66) or they can cut a deal with AT&T to give AT&T 10x10 B12 (AT&T has the lower C block), but I'm not sure what that deal would be if trading like for like (vs. AT&T handing VZW their upper tiny slice of B5, giving VZW 15x15 to play with in that band post-WCW-acquisition). EDIT: Just looked at AWS spectrum again, and if AT&T would rather have 10x10 B12 than 2x 10x10 AWS, they could swap AWS-D for VZW's 700B block. That would give VZW 20x20 AWS, and would take AT&T down to 10x10 + 5x5...which they'd likely be fine with as they have 20x20 PCS, small cells in the busy areas, and as a result of the transaction three 10x10 chunks of spectrum in the area below 1 GHz. And if VZW traded 700A to T-Mobile for PCS-E VZW would have 20x20 PCS as well. Which is quite useful in an area that's macro-only for VZW and likely not dense enough for proper mobile usage of CBRS or C-Band (and an area where VZW doesn't even run DSS now).
    • Yeah, $250 credit for an S22 is awful. tbf last year they didn't have solid upgrade credits until mid-late April, which is when I paid $225 to swap my S21 for an S22. Happy to wait 'til then for that kind of deal, though I'll be annoyed at battery life in the mean time.
    • Miserable upgrade credits from Samsung this year unless you want to rely on carrier financing. Sticking with S22U for a while. 
    • So far we've documented close to 100 Sprint conversions in NYC with permits still rolling in and that's only what we've identified manually. Tons of sites get converted/updated without permits so there's potentially a lot more that we haven't spotted yet. There are also dozens of sites that are still broadcasting the keep PLMN, some have been decommissioned but historically the vast majority have been converted.
