Hasn't Sprints data service always been called "Vision" of some iteration?

 

Prior to PCS Vision, Sprint's cdmaOne circuit switched data service was called Wireless Web. Circa 2000-2001, when VZW was still getting its act together following the merger that formed it and Sprint was the only carrier to offer seamless wireless data service in all major markets, Wireless Web was kick ass.

OK. We now have a Motorola Photon on the way after a member donated his device to the experiment. So now we have a total of eight devices that will be a part of the 1x/EVDO radio performance article

Robert may have to adopt Buddhism in order to manage all of these handset RF tests.     AJ

In order to get reasonably valid results, I recommend a strict testing protocol: all handsets be set to a single mode (e.g. 1X only or EV-DO only) all handsets be set to the same sampling interval

I feel quite certain that guy in the video could tell you where you could get some weed.

Robert - can you comment on battery life of all the phones you're testing? No need to get into detailed tests for each phone, but just general impressions as to how the phones compare to one another.

EVO LTE = Great

Galaxy S III = Very Good

Galaxy Nexus = Good

LG Viper = Good

Any initial results yet? I'm not sure if I missed them or if you are trying to find time for this experiment. I'm sure juggling all those phones must be a daunting task!

 

I have one more batch of testing to do. Each batch takes a lot longer than I imagined before setting out. I hope to complete the work some time this week.

Are you going to be able to include any LTE tests? (Thought maybe you made a secret detour on your vacation.)

No. I'm going to release an article on the 1x/EVDO on 850 and 1900. I will be in Waco on Labor Day weekend, and I will test the 4 LTE devices I have there then in a separate article.

What are you going to be doing in Waco on Labor Day Weekend other than testing LTE?

I am there for a family function. My LTE testing is incidental, not the purpose.

Family function? Hopefully your family isn't as dysfunctional as mine is, lol.

Cleaned up the apk list on my EVO today and trimmed stuff down I will never use. Blocked a few permissions on apps that were causing some minor wake locks. Used better battery stats to identify them. And wow! Normal usage today and after 10 hours off the charger and I had 80 percent battery left. Awesome!

What rom are you using? I'm using Viper4g and it's awesome.

Tried viper way back. Went to meanrom. I have a script that cleans and mods a few things though.

 

One day I will just make my own since I can't find one that has everything set like I want. Like for one, if the app is available on the market, YouTube, facebook, etc it should not be on the Rom. Get it from the market if you want it.

 

Digging into things and trying to get rid of the ugly white on the settings screens and email screens. Maybe then I will put something together.

The new Viper that was released last week is very good. Not sure if that's the one your tried or not.

 

I might check it out, it had a bit of fluff to it though. Will have to see what I can clean up before flashing.

 

TWRP and titanium backup make it so easy to setup a new blank Rom and then flip back and forth between them on the go.

How is this test going to be better than using what the FCC report shows #s wise?....I guess showing the lte signal versus evdo and how that looks to an extent but I'd think the FCC #s would suffice for telling which phone had better signal than others generally....

 

Just trying to understand the overall purpose here as I don't see the need for comparing signals across phones since that's been done with high tech equipment at the FCC already...

Sgt., the FCC is not concerned with RF reception. The labs that are certified to submit test results to the FCC assess only RF transmission.

Ahhh

 

Okay so we end up making a lot of assumptions on things when trying to deduce the phones signal reception ability when we only base it off the FCC figures....(obviously ignoring the radio software as we all know this can vary drastically bw OEMs.)....that is if we are looking at this from a hardware perspective mainly...

 

On the same page now though... :)

 

What will be used to judge the signal? Going to go off the internal menus?...if so are the values there not effected somewhat by how the software calculates them or are the flat numbers/values/calculations used across all OEMs?...

Like how we know you can tweak it to show more/less bars depending on the signal # given....I dont know how the device is determining those internal numbers, hence the question.

Here's another to throw in the mix of thoughts... Two receivers side by side are receiving the same signal strength, but one is more "efficient" and shows a higher signal quality. The same can also be said on the send side. One radio might be more powerful on the signal power but it's not a high quality signal like another lower powered phone. One of the reasons you see loopback tests on many two way devices.

 

To really compare the phones on just debug screens alone you would also need the stats the tower has on receiving the signal from the phone.

 

I'm very interested to see the test article when it comes out.

      Dish Network/Boost Mobile cell/5G buildout thread

      Definite usage quirks in hunting down these sites with a rainbow sim in a s24 ultra. Fell into a hole yesterday so sent off to T-Mobile purgatory. Try my various techniques. No Dish. Get within binocular range of former Sprint colocation and can see Dish equipment. Try to manually set network and everybody but no Dish is listed.  Airplane mode, restart, turn on and off sim, still no Dish. Pull upto 200ft from site straight on with antenna.  Still no Dish. Get to manual network hunting again on phone, power off phone for two minutes. Finally see Dish in manual network selection and choose it. Great signal as expected. I still think the 15 minute rule might work but lack patience. (With Sprint years ago, while roaming on AT&T, the phone would check for Sprint about every fifteen minutes. So at highway speed you could get to about the third Sprint site before roaming would end). Using both cellmapper and signalcheck.net maps to hunt down these sites. Cellmapper response is almost immediate these days (was taking weeks many months ago).  Their idea of where a site can be is often many miles apart. Of course not the same dataset. Also different ideas as how to label a site, but sector details can match with enough data (mimo makes this hard with its many sectors). Dish was using county spacing in a flat suburban area, but is now denser in a hilly richer suburban area.  Likely density of customers makes no difference as a poorer urban area with likely more Dish customers still has country spacing of sites.

      Mike if you need more Dish data, I have been hunting down sites in western Columbus.  So far just n70 and n71 reporting although I CA all three.

      Good catch! I meant 115932/119932. Edited my original post I've noticed the same thing lately and have just assumed that they're skipping it now because they're finally able to deploy mmWave small cells.
