    OK, so I finally found something I am not happy about on "MY" hero (hahaha)

    Not really, but I though that would grab your attention.


    EvDo Rev. 0 or A


    I had Rev.A on my prior phone and not now(same location). I read in the Sprint user forum that they say its(Hero) just reporting it as rev.o but you get the rev.A speeds if it is available. I have speed tested and speed tested and find this to be erroneous. I have gotten MAX - 800Kbps down, 250+ up with a 300 avg. ping. Hmmmm, I certainly remember getting over 1Mbps on my old palm, lol...

    A few things...

    1. Is anyone in the same thought as I, that Sprint did this to throttle the connections and limit bandwidth demand from the influx of phones hitting the network?

    2. My last phone allowed the setting (EvDo) to be manually set as default via codes... ##3282# (I don't remember if that is it exactly but it's just for example) and I wonder if the HTC phone has the same setting or FORCE rev.A capacity?

    Lastly, is this something that has been mentioned in the coming update? I remember reading it was supposed to be addressed in the maintenance release but obviously it had not been. Some phones have it, most don't...

    Any information or opinions on the subject is gladly appreciated.

    I should have mentioned that I read this too, sorry and thank you for the link.

    Personally, I don't agree(that it is just an indicator glitch). Like I posted, I have done speed tests which don't quite measure up to the Rev.A throughput... I am consistently in the Rev.o band and not exceeding it...

    EVDO Rev A: 600Kbps - 1,400Kbps Down (with bursts to 3.1Mbps); 500Kbps-800Kbps Up (with bursts to 1.8Mbps)
    EVDO Rev 0: 400 - 1000Kbps Down (with bursts to 2.0 Mbps); 50 - 100Kbps Up (with bursts to 144Kbps)
    1xRTT (Sprint & Verizon 2G, AKA "NationalAccess"): 50Kbps - 100Kbps with bursts up to 144kbps Down/Up
    EDGE (AT&T 2G): 50Kbps - 100Kbps Down/Up
    HSPA (AT&T 3G): 700-1700kbps Down; 500-1200kbps upload

    It is possible that I am wrong with my previous experience, but I am using the phone in the same locations. Ultimately proof is in the pudding, I don't care what it says, its what I'm getting in speed that is relevant. Just like the battery, I don't care what it shows, but how long it lasts, lol.

    Maybe it might help, if Hero users post their speed test results and locations and what their Hero's are reporting with respect to the Rev.0 or A on their phones and we could all see? Make a comparative study...

    I'll edit this later and place my speed test result here.

    .93mbps down
    .18mbps up
    334ms ping
    1:38 p.m.
    NY - W. VA test server...

    Not bad. Better then I have been getting but we'll see... the ping is terrible though. I'll keep playing and post more results later.

    Just an idea?

    Thanks again PDragon...

    i am nowhere near an expert on this subject and don't claim to be, but isnt' the high end of the Rev 0 speeds somewhere around 700? That's the impression I was under. I have gotten anywhere from 300 to 1500 on the mobile network

    Well, since my OP I have been checking at least a few times a day. I have been getting consistent readings from speedtest.net. The tests are primarily from NY to servers in NJ, D.C., P.A., etc., not too far so the results should be more respectable.

    Troubling is the high ping but... my issue is not with the phone. It is more so with the network and carrier. They advertise 3G and the related speeds, I am IN the (EvDo Rev.A) coverage area, but the phone is reporting otherwise and the test's prove this as well. Although the speeds are respectable, they are NOT in the Rev.A level of performance.

    I would have hoped more users wanted to verify (and post results here) that the services they are paying for are being delivered, but to each his own. I will be in touch with Sprint to see if there is anything I can do to reduce the ping response and increase throughput performance... We'll see...

    Thanks so far for the responses... Hopefully more will come in.
    Nick325i - those are awesome speeds... What is your location if I may ask?

    Your ping might not have anything to do with Sprint. You might already know how a ping works. But for those of you who don't here goes.

    Latency and speed are two seperate issues but can effect one another. A ping is a single packet of 32 bytes sent from you all the way to the server that is your final destination. This means that depending on how far away the final point is physically, the server could have 20 routers in between that are run and controlled by different internet providers and companies.

    With all of that said...

    If one router is having an extremely heavy traffic moment or any actual issues. Your ping could be spiked to 500ms easy. This is especially true in high population areas.

    Thanks, but yes, I am aware of PING and what it does performance wise, the latency could be the heart of the issue regarding the relative speed I am experiencing. The Cell tower is not far either, less then a 1/4 mile from my location so...

    I just checked again...

    .84 Mbs Down
    .20 Mbs Up
    329 ms Ping
    -75~85 dBm 14 asu Signal

    Interesting thing I have observed... the I.P. changes all the time! Everytime I have gone back to SpeedTest.net it indicates a different I.P. for my phone. My old phone had the I.P. address static, this dynamic I.P. is interesting... Hmmmm...?

    Anyway, so far... Rev.A indicated phones are showing a higher throughput, with the exception of Nick325i...

    Thanks for the responses... Keep them coming!

    I jsut did it with the WiFi turned on,

    Down:3611 (3.53)
    up: 837 (.82)
    png: 97

    Is that good?
  15. nick325i

    That is excellent! The phone being able to sustain that as throughput on WIFI is good.

    Forgot your ping and Rev. type?

    Keep em' coming...

    Like I said, so far, the Rev.A Phones "ARE" indicating a higher downloading speed... Hmmmm...

    Just now.

    Png:72 ms Dwn: 5204 Up:850 From Morrisville to the Wilson, NC server...

    Could someone do me a favor, and tell me,
    Is the Ping number supposed to be higher or lower to be better... (Down, and up I understand to be higher is good? Right?:thinking:

    Ahh shnikes, I was on WiFi, btw... those numbers could be misleading. lol.:D

    Lower....it's the time it takes for a packet of data to complete it's journey. 72ms is great.

    Thanks but you are measuring the WiFi speed, you must turn off the WiFi when connecting to measure the Sprint network speed and relative EvDo performance.

    I have consistently been in the Rev.0 bandwidth...

    The ping is the a tool which is used to measure the pathway between two points on the internet.

    Ping operates by sending an echo request in packets of data to another I.P. address, usually a server and waits for an ICMP response, sometimes casually called a pong, lol. This pinging measures the round-trip time and records any lost packets as well in the transmission. The results you see in these speed tests are a summation of the data, but a detailed report gives much more information. It will show you the addresses of servers transmitting the info you sent until it arrives at it's destination, the time to hop from each place to another and if there are any lost packets along the way. Generally, yes, the lower the time from one place to another the better. But fast speed with packet loss is not good either because then a repeat transmission is required to complete, etc., so anyway...
    (Just for those who might not know)

    Low Ping is Good :)
    High Speed is Good :)
    But High Speed is not measured by low ping or vice/versa :)


    Keep them test results coming, and thanks a bunch!
