[Q] Increase signal (radio) power on nexus 5

mmojica53 · May 30, 2014

Hi, I've been searching about the problem and I didn't found anything.

Here is the thing, I compare the nexus 5 LTE signal strength with the iphone 5s and when iPhone has 2 or more LTE bars, the nexus 5 doesn't get bars, even the nexus switch to 3g and the overall of the LTE is unstable compared with iPhone. That comparison is based on medium LTE signal strength with the same carrier at&t.

I saw a post it is possible by software increase the Wi-Fi signal strength, so my question is, can I increase the signal (radio) strength?

I've been trying flash different radios, build. Prop tweaks, change the prl preference, anything I found in Google, but noting happen.

you can try adding these 4 lines to your build.prop(and reboot)..

ro.ril.hsxpa=3
ro.ril.gprsclass=12
ro.ril.hsdpa.category=27
ro.ril.hsupa.category=7

Did you find this really works? curious...
are these only for LTE or like a universal setting for data signal?

works for 3G/lte. what it does is it lets you get to your top data speeds faster, making it feel like your connection is better/higher quality. it might improve data speed as well. i have a thread with these lines, most people say they got a difference, while some didnt have any difference. you cam try, it wont hurt for sure

I already have those lines in my build. Prop

These are my parameters

Code:

ro.ril.enable.dtm=0 
ro.ril.gprsclass=10 
ro.ril.hep=0 
ro.ril.enable.3g.prefix=1 
ro.ril.hsdpa.category=8 
ro.ril.hsupa.category=6 
ro.ril.hsxpa=2 
ro.ril.enable.a53=1

I put the parameters you post, and I didn't see difference. I post screenshot of my signal

You've got really great signal if the dBm and asu is anything to go by. I get much lower than that. The bars are not to be used for comparison. Try and compare dBm or asu to the iPhone not "bars"

hmm.. whatever rom you are using is using old lines from a much lessor device! looks like they just add in anything to your rom without actually looking what it does. get rid of those lines, and copy/paste those four lines i posted only, with their numbers. then save it and reboot for it to take affect.

OK, but I mean in areas when I do not have coverage the iPhone has.

OK, I will, thanks for your help, I will post my result

Edit: I put the just the 4 lines and I didn't see difference, -98dbm 42asu obviously I rebooted my phone

OK, I'm just saying your bars in particular are giving what I would call a bad indication of signal strength. Just ignore the bars and read the asu. My phone shows full bars at half your asu.. so something is off there.

i get 1 bar at home, but get 60mbps download speeds at home(lte)

I cant say for LTE specifically as I dont have it, but I can get a good 20 Mbps and full bars on about 20 asu

My N5 is pretty much as good as the wife's Moto x for signal. So I think the N5 does pretty darn good with it's radio! I had to go outside to make calls and even text sometimes on my S2. Lol

Actually, I care more when my phone switch to 3G and the iPhone still in LTE stronger. I don't have both phones right now to put the screenshot, by the way, I created this thread to figure out how increase my phone reception.

I just added those to my build.prop..

I check the dBm and asu before and after... before I was at around -89dBm and 12asu.. now its -99dBm and 9asu...
So I guess its working? :fingers-crossed:

Not work for me!

Any other suggestions?

The only other way is a booster. They're very expensive and better read the reviews on them to get a feel for if they work for people.

In Canada here they are $300 to $400 dollars.

There's really not much else you can do.

Normally I'd say get a Motorola, but as I said, my N5 is about as good as my moto x.

I think -89dBm is better than -99dBm.

Yes, lower is better.

Just stay off the .23 radio and it should be good.

Thanks everybody, any other suggestions? I can't believe Android don't allow modify those values by software... I saw a extra antenna, you install that in the back cover but the nexus cover isn't removable, "not for the user"
