[Q] Better Wimax Signal EVO 4G

So I've been up searching and searching and searching to see if anybody has found a solution to better increase the 4G connectivity for the HTC EVO 4G and the only thing I've come across from is
http://forum.xda-developers.com/showthread.php?t=925898
My question is, can we make the same changes on the exact same fields and have better signal for our EVO's

Does anybody know anything about this??

The main thing you can do to get a better Sprint WiMax signal is to go outside. It just doesn't work very well indoors. I'm not serious about actually walking outside just to use 4G, but unfortunately am serious when I say that the frequency Sprint/Clear uses is just too high to get inside well.
I'm on CM right now, so I can't go hunting for a similar value in the Evo's EPST. It probably would increase the battery drain when using 4G though, if it even really works at all.

Going outside isn't gonna work for me, reason being I'm trying to use 4G tethering for my xbox.

I wasn't really being serious about going outside...i'm just saying Sprint's 4G network doesn't work that well inside unless there's a tower in your backyard.
Also, latency on WiMax will be pretty bad, which matters for gaming. You'll get killed a lot.

I use to use those and they work a little better its not really a stronger signal but I was able to connect in doors to my ps3 and stay connected longer.

Best radio fix for a weak wimax signal?

Has anyone tracked down a good radio fix when wimax doesnt stay connected? I know they have radio updates but does anyone have one in particular they would recommend?

No. Unless you understand the risks do not flash a new radio ("modem" in Samsung land), there is currently no way to go back to stock (EG30).

There was a thread here on tweaking that. You have to dial a number on your phone and edit something.

Tweaking the radio
I know there was a fix to tweak the radio by dialing certain numbers, but i'm curious if anyone has done it and saw a big improvement in their 4g signal.
Considering sprint will probably not expand wimax anymore, i'm screwed with this weak signal.

Both posts above are right. It is in here. I will try and post a link if I can find it. I did the same tweaks on my OG Epic and they work well for me. There are certain setups depending if you are always in a good signal area or if you want it to connect faster,etc
Sent from my SPH-D710 using xda premium

Essentially you are looking to lower the threshold for signal strength to connect and raise the timers for disconnect. It's not going to make your signal any better. It's only going to make it more usable--maybe. It could also keep you "connected" and not transmit or receive anything. Not too sure how that would be useful.

Well, i know there are things you can type for sure, but i've never heard from someone that has tested it and said it improved their 4g experience.
Was trying to find a signal amplifier because i'm in a weak 4g spot, but i'm not spending 600 bucks for something i should be getting anyway with my "premium data" 10 dollar addition to my bill from sprint.
Pisses me off that they expect their customers to be happy they are switching to LTE. Me and my expensive wimax phone are so happy sprint is changing their cell tech to LTE..

They are useful if you are in a good or fair 4g area. I live in a full bar 4g area and shortened the connect time and lowered the minimum signal strength a bit. I used same settings that I had on my OG Epic. If you don't get it now it most likely wont do anything or MAY get you 1 bar if you are in a fringe area

4g or 3g battery life

So, I read somewhere that 4g is more similar to wifi, indicating that 4g is better for the battery if you have good signal. But I notice the exact opposite, 4g kills my battery whereas 3g isn't SO bad. Can anyone confirm this?

Sent from my SPH-D700 using Tapatalk

I use 4G frequently while at work. I obviously don't use my phone as much while I'm at work as when I'm not, so it's tough for me to get a good comparison.
It does seem to me when downloading bigger items, like ROMs, 4G will take up more battery than 3G even though it will certainly take longer on 3G to accomplish the same thing.
And for what it's worth, I do get a good 4G signal while at work too, so it's not like it's bouncing back and forth between 3/4G.

From my own personal experience;
Wifi>3G>4G

Imho I think it is modem/kernel/ rom related. I certianly think there was a period that wifi was sucking the life from my phone and 4 g was sipping. Presently I think I am doing 3g>wifi>4G...but I have seen this flip arround on diferent versions.

Thanks for all the replies (literally). I've seemed to notice exactly what your saying though, I was just wondering because I heard somewhere 4g drains less battery in high signal areas. I usually get 2/3 4g bars, so id say mine is ok, but it definitely drains faster than 3g
sent from my touchwiz 4.5-ed epic

It doesn't make much of a difference for me. Probably though because my school is so close to a 4G tower? I mean I can literally see it.

4G is a seperate radio so would require more power. 3G is tied to the CDMA radio. Wifi uses almost no power when connected. So I get days of standby on weekends at home on wifi.

Funny, my device gets the opposite with 3g vs wifi. My sleep policy is set on 'never', but wifi has drained the hell out of my batter since Froyo. It's nearly as bad of a drain as 4g, when I was in a 4g area to test.

+1 and also since froyo. How I long for the wifi battery sipping days.

4g spectrum runs at a higher frequency rate than 3g. Therefore, 4g will drain ur battery a lot faster, especially if u have weak or weaker signal strength. Wifi, is low aplitude frequency rate, meaning..it an open frequency , therefore, does not require much power for high speed. 3g is moderate frequency rate. Just to clearify..3g and 4g are cdma, depending on carrier. Support information regarding can be allocated at www.phonescoop.com

I have no doubt you are technically accurate and it could be the implementation and how they are managed. If I take a full battery and leave one of these on at a tome...as of stock froyo (I think some roms may have had different results) and all gb 3g certianly is usong about half the battery being used as 4g and wifi consistantly uses more.
Sammy should talk to u guys n get theeir sheit fixed.

it also has to do with power time managment in the kernels. i discovered that between the different kernels i have tried and xda. you just have to play with the different roms and kernels and see which gives you better results.

Terrible signal

I'm sitting here at work and I check my signal strength it say -91. When I had my Droid incredible original it would have a signal strength of around -62. Do I have one of those defective nexus phones I keep hearing about? Also in my house I go from
-120 to -140 what's up with that? My cell standby says 73% of the time that can't be good.

Are you on LTE? If so, the Nexus properly reports the LTE signal, which may be worse because it is not rolled out as widely as the 3G on your Incredible.
Also, the radios on the GNex aren't the best, as is widely noted and complained about.

I am on lte so if I change to cdma it'll have better signal?

Outside of the appearance of a "weak" signal, does the device function? Can you make a call? I have a signal of -102db at work because we have crap coverage of all kinds and can still make a clear call on my VZW GNex. Outside of the building I get more bars (like it matters) and can make the same phone call. Obviously data speeds are slower inside than out, but communications still flow.
Edit: Your giant 4.65 inch screen is probably using more juice than your weak signal. It's the price of a big display.

Yes I still can make phone calls, but when I first noticed it I had my wife call me and it didn't ring. So I'm afraid that I'll end up missing phone calls. I'm a firm believer in the "if you pay for something it should work and not be defective". Also when I talked to Verizon the tier two tech said it couldn't activate/communicate with the device at the the switch. He suggested a new sim or phone. He also said with the worry free guarantee I could switch out the phone for another. I would have to pay the difference if it cost more. I'm now wondering if since I got this phone for free would I have to 299.99 for a phone, or since it costs 299.99 at Verizon could I switch it out for a phone that costs 299.99?

I'm pretty sure it only means the difference in MSRPs between the two devices. Had the same situation a few years ago with Sprint when 3 Instincts went bad. Upgraded to a Touch Pro and only had to pay $100, even though I got the Instinct for only $50 on special.

I have AT&T. Been using the GNEX for months (before it was available on Google Play) and it shows ~1 bar/0 bars in my basement. I recently got a new GSM RAZR MAXX and in the same basement, I get 4/5 bars and never drop a call ever.
That says something to me. Quite simply Samsung radios aren't nearly as good as Motorola's radios.
I'm actually selling my GNEX and keeping the RAZR.

Do you have a Verizon Galaxy Nexus? Most likely

Yeah its a Verizon nexus. Man I really like this phone the screen is amazing, I get OK battery life, and the 5mp camera is really good in low light. I wish I could get the reception of the razr maxx as I'm hearing it is greatly superior. Plus with the razr HD coming out it makes me second guess. If I keep switching sim cards and phones until the razr HD comes out what would my chances be in getting that one as a trade in?

Slim-to-none in my experience. I think it's always been a tradeoff between Motorola and Samsung. I love Samsungs design and screens and ease of rooting/unlocking compared to HTC and Moto. For me, the carrier (Verizon) and their excellent network in my area more than makes up for the lack of the GNex's signal-pulling ability.

I get lousy reception on my gsm galaxy nexus on Bell too. This is my second nexus and it's definitely no better than the first. They keep making phones thinner and thinner and at some point radios, batteries, internal storage have to suffer. I like the phone but I can't wait until my contract is up and I can check out the new Nexus'.

No time without signal that high is killing his battery more than the screen. Cell phones want to remain in contact with the tower at all times, the poor signal the phone tries that much harder to stay on the tower.

If you're using 4G, remember that 4G on ICS and higher (I believe it's all ICS/JB devices) reports RSRP signal status, rather than RSSI. RSRP shows a much lower number for a similar signal level. Read this thread for more information.

I think I pinpointed it to the fact that when I'm connected to wifi I'm not connected to the mobile network. Does this make sense? when I'm not connected it is reading it as time without signal.
