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.

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.

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

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

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.
