EvDo Rev A_EHRPD on Verizon prepaid

[rybshik]

If 3G/4G/LTE modem (such as 4510 or 4620) is flashed to $50 Verizon prepaid, will it take an advantage of EvDo Rev A_EHRPD (over EVDo Rev A)? Is EvDo Rev A_EHRPD any better than EVDo Rev A?

In other words, if flashed to $50 Verizon prepaid, will 4620 be any faster than 2200 in Verizon 3g/4G/LTE coverage area?

I believe the EvDo Rev A_EHRPD is just for LTE phones to be backwards compatible with the 3g network. Verizon prepaid does not get any 4g or LTE i use a 4510l flashed and i am on Rev A

he is right ehrpd was made to allow a smooth fallback from lte to 3g/1x or what is available so on a device that doesnt get lte to begin with how will it know how to handle ehrpd,the answer is...it wont.so dont use it,whether you have the lte modem loaded or not it will only give you problems on any device

Being within Verizon LTE coverage, I activated Mifi4620 on Verizon, forced it into 3G mode and compared the download speed with a Mifi2200.
MiFi4620 appears to be 20-40% faster as well as it's ping time is less. In MiFi4620 diagnostics window, it shows "EvDO Rev.Ae" which is "EvDo Rev A_EHRPD", while Mifi2200 is obviously Evdo Rev.A.
So?

So?SO is the 2200 capable of EvDO Rev.Ae? That would be where I would start...

4620 is a lte device 2200 is not,did you not know that? did you not know that the processor in the 4620 (mdm6600) is far superior and renders speeds of 5 to 12 mbps compared to that of the 2200 which renders a speed of 500kbps to 1 mbps......

read my post dude,i said " so on a device that doesnt get lte to begin with how will it know how to handle ehrpd,the answer is...it wont.so dont use it"
so of course it is going to be faster than the 2200. like i said do not use ehrpd on non lte devices,but sounds like you will anyway.

do not use ehrpd on non lte devices.ok, apples to apples. Now I only play with 4620 activated on native Verizon LTE account, with SIM card. The device is forced to EVDO mode (Rev A_EHRPD).

Experiment-1: SIM card is enabled (RUIM only mode). Device reports PRL 15226, which I assume is LTE+EVDO PRL.

Experiment-2: SIM card is disabled (NV only mode). Device reports PRL 53175 which is the most recent EVDO PRL for my location.

When I compared speeds, it seems that in Experiment-1 speed was slightly better. Although it might be just a "placebo" effect.

So, LTE+EVDO prl might somehow provide better connection than most tecent EVDO PRL. Possible?

No. The only difference would be QoS setting favoring postpaid customer over prepaid customer on that tower/site. Anything else is wishful thinking at very best.

QoS setting favoring postpaid customer over prepaid customer on that tower/site.. Is it only set on Verizon side/tower? Or in modem settings as well?
