Antenna DBM strength - Galaxy S III General (US Carriers)

Can any one give an antenna signal strength DBM wise? Whats the signal strength when you receive full signal bars.

I wish I could help but I want to know the same. Preferably someone coming from a nexus or gs2 and familiar with what they used to get. Hoping gs3 has better radios

The questions as framed are really about how the manufacturer (and carrier?) define "bars" -- which is mostly a marketing concept invented differently by different vendors to obscure scientific facts. We might as well call them "unicorns." FWIW for comparison, my current phone, a Samsung Epic 4G, reports "bars" mapped to the following dBm values:
0 bars = -106 dBm
1 bar = -101 dBm
2 bars = -96 dBm
3 bars = -91 dBm
4 bars = -86 dBm
5 bars = -76 dBm
6 bars = -65 dBm
In my testing, I have not seen values reported between these intervals.
So it would be interesting to see how the marketing-driven designers have defined "bars" on the Sprint Samsung Galaxy S III, if only to translate that into common units that are not marketing gibberish.
Another question generally relevant might be this, to describe the receive sensitivity of the radio: After translating "bars" to dBm, what is the worst dBm reading you can experience and still have the phone function. Or perhaps plot lots of Speedtest results at various dBm readings of strength.
Note that reported strength -- whether stated as "bars" or dBm -- has nothing directly to do with transmit strength, and all this is about two-way radio communication.

Well my signal at home is crap so I can tell you 1 bar is -100 through -102...
And I keep getting a data roaming pop up even with the roaming guards turned off, annoying, anyone else dealing with this?

I don't care about bars. More so dBm if can. I have a nexus and a razor Max on Verizon. I was with sprint. I'm looking to get opinions

Kegacide as far as your raining pop us go into settings and networks and start disabling and enabling so that you don't get those anymore. Same w gs2 and all Samsung sprint phones

I turned off the roaming guards for everything, even turned them on, then off again when the pop up came up and I clicked for show again....
Even still the data roaming signal keeps showing up in my notifications bar, which is two problems, one my bad connection, and two the annoyingness of the pop up...
What do you mean start enabling and disabling things, like what?

Honestly you guys are silly all non Motorola cdma devices perform identical on sprints network. The inconsistencies you guys see is sprints network not the devices.

If it seemed gauge I'm sorry. Been a while since I been on sprint but you can unchecked/disable some of those boxes and the data roaming will not pop up. I have done it since the epic 4g.

reception sucks!

I hate to say it but I am having 3g issues. By that I mean no 3g and one to two bars. Usually I have perfect reception.

i've noticed on the incredible that my displayed signal strength isn't as strong as it is on my droid. haven't noticed a difference in call reception or data speeds though...yet.
Eris users have noticed the same thing as you bzbz when compared to the Droid. Could be the cpu or something else HTC vs Motorola.

I noticed the same thing but my download/upload speeds are just as fast if not faster. I gave my Droid to my mom and took her upgrade so I have both side by side, off WiFi downloading a movie and the Incredible is actually 20-50kbs faster than my old Droid and yes the Droid is over clocked with petes 1ghz kernel.
I have had the Incredible for a couple of days, and I've noticed a lower displayed signal strength than I'd see on my Droid in the same locations.
But I've not experienced any reception issues, and my internet speed seems the same or faster.
This is what I expected. We all know that you can't count on those reception bars to compare different phones, and also that Moto tends to have better radios/reception than everyone else anyway. As long as you're phone's radio is close to Moto's in the ability to make/receive calls, then normally you're not doing bad.
well it's good to know that the signal strength concern may be more of a "cosmetic" issue than a legitimate performance issue.

It is definitely cosmetic, the newest radio i have installed on my eris does the same. The reception on my eris is better then my friends with the older radio, but he has more 3G bars.

It may just be the way HTC displays the signal. I know on the Touch Pro 2 and Touch Pro, the signal indicator frequently shows incorrect (lower) signal strength but works fine.
I compared signal strength between my BB Curve 8330 and my new Incredible.
In spite of the indicated signal strength being lower on the Incredible, the dBm was the same. It's only one location and one user, but I suspect it's not an actual signal strength issue.
i used my incredible all day. i work in a downtown area with many tall building surrounded and i still got a good 3g signal and speed.
from Boston.
the 3G speeds on my incredible are slower that my 2G G1 running on AT&T. i get les than 200 kbps downstream. My friend with a droid standing in the same room will get aound 1100 Kbps. What gives??
if you are haveing a tough time with a signal.. I update my roaming towers... I had an issue today where I couldn't get much.. I did *228 option 2 and it updated my roaming towers and have had no problems since... sometimes you need to do that with a new phone so it knows exactly what towers to look for
tried the *228 to update. Update was successful but no improvment. still have very slow data speeds and terrible call quality. reception stays about around -100 dBm
I'm also noticing what appears to be poor reception. I was getting better reception with my Droid than I am with Incredible. I've tried the *228 last night and this morning but that hasn't helped. Hopefully there will eventually be some kind of software fix for this. I'm seeing other threads on other sites with the same kind of complaints so I don't think it's a select few who are experiencing this issue.

Your speed will depend on what tower your connected to. on my Eris, I've gone from 1mbps/0.70mbps in New York, NY to 2mbps/2mbps in West Haven, CT. It's not the phone. The newer radio on the Incredible will show less bars, but your signal strength will be fine .(dBm)
My phone keeps dropping 3G my droid never has done this in the location the incredible is. I will go into airplane mode then back out and I will have 3g again
Over at Androidforums there is a thread going regarding reception issues. On page 2 is some help in running a debug on the phone that will give you dbm levels and some other info. I'm not sure how to use the info the debug gives but perhaps it may be of some use to someone here.

You don't need to go into field test mode like this guy said, all you need to do is from the home screen > menu > setting > about phone > network.
Here you will see signal strength (typical between -100 to -80dBm) the closer to 0 you are the better your signal is (ie: 80dBm > 90dBm)
Hope that clears up some confusion. I've tested both the motodroid and the incredible side by side in a location with low signal and can say that my incredible gets better signal than the droid, even though the "bars" don't indicate as such.
my signal always stays at -81, is that a good thing?

Possible bug in Fascinate's signal strength

I believe there is a bug in the signal strength indication on the Fascinate, the one that shows the signal strength in -dBm.
You can see the signal strength of the cell signal on the Menu, Settings, About, Status screen. Or you can place a widget on your Home screen. There are several widgets available, I'm using Mobile Signal Widget.
I have a network extender, which basically creates a cell tower right in your home. With my Motorola Droid, I used to get signal strengths down to about -50 something and 60's in indicated signal strength. I can hold both of our Fascinates right next to the network extender's antenna and they will read no better than -86 dBm. So far I've seen signal strengths from -86 dBm to -106 dBm (terrible).
I believe there is a bug in the software (Baseband) on the Fascinate. Previously, I thought the hardware (antenna/radio) wasn't very good, but now it may be software related.
Has anyone seen a signal strength stronger than -86 dBm on the Fascinate?
That's a good point. Mine has never gone below -86dbm either. It fluctuates between -86 at it's best and -106 at it's worst.
Ill keep an eye on this with my phone

I have no experience with cell phone radios so take this with the appropriate helping of salt.
Most radios have input protection that attenuates any signals greater than a set maximum level to prevent damage to the radio. I'm guessing the Fascinate reports it's receive signal level post input protection. It appears you just discovered this threshold for the Fascinate. Honestly, -86 dBm is plenty of signal, anything more is just for show
Again, I'm only speculating here.
Martian21
Interesting theory. I have emailed Verizon support as well. Hopefully, I will get a technical response and not a canned response from them.
With mine, it only fluctuates in -5dBm increments lol. I thought it was a litle wierd. I've seen -86, -91, -96, -101, and -106 lol.
As far as what the OP is talking about, my BB Tour (alltel) is the same way. It won't ever display anything lower than a -80.
Anyone else have a consistently high TWS(Time Without Signal) percentage? Mine almost never goes below 50%, and I've seen it up in the 80s. I think my battery life is really suffering from this. You can see yours in Settings > About Phone > Battery Use > Cell Standby. I've tried a few "fixes" that I've found through researching the issue on other android phones in general, but haven't seen any results.

I was thinking about this the other day. Is it possible "time without signal" is simply a poor translation? The reason I ask this is when taking my phone off the charger overnight, I went directly to this setting to see what it reported. The phone reported having been unplugged for 2 minutes and already showed 5% TWS. I had been looking at the phone the whole time and didn't see it drop at all. What I did see is it going from 3G w/ arrows to 3Gd. So maybe this percentage isn't time without signal but rather time not active (i.e. 3G d).
I agree w/ the 3g d, I did not update to DI01 yet and it said I have 20% TWS throughout the day, but the phone didnt make a no service sound.
On my drive home everday I pass a Verizon owned tower.
I've stopped at a liquor store about 200 yards away from it and they maximum signal my Fascinate would pull down was -86dBm (4 bars as well).
My Cell Standby is usually around 11%.
Battery life of my Fascinate is very good.
xliderider: Any news/word from Verizon on this? What kind of Network Extender do you have? Got a brand/model #? Been thinking of picking something up like this.
So it isn't just my phone. My Fascinate goes from -86 to -106 as well. I had my Droid and Fascinate sitting next to each other, both reporting 4 bars. I went into status, and my Droid's signal strength was -77. The Fascinate was at -86. It's gotta be capped.
You're holding it wrong.
Sent from my SCH-I500 using XDA App
You are probably right. With 4 full bars I can't get better than -86
I've been having the same problem...I was told by Verizon that it just has a "weaker" antenna. I go throughout the day with about 20% TWS. Never had that with my other Verizon phones.
do you get dropped calls or otherwise poor service?
I am returning my incredible due to dropped calls (while at home) using Verizons network Extender. I have had the incredible since April 29th (I believe that was the first day it was released). I have had the signal boosted twice by Verizon but still can't get close to 40' without dropping. One thing I noticed on the incredible while in the same room with the Extender is it would read let's say a -86dbm before placing a call then when placed and on the Extender network the signal would automatically go to -56dbm (stronger signal than -86dbm) and then back up after my call. What I saw was the Extender wasn't active until you make a call... Having said that, I am hoping the Fascinate will be better than the inc was... I will let you know when the Fascinate gets to me Wed or Thursday.

Sounds like it could have the same problem that affected the Vibrant. It NEVER showed higher than -81dBm, and would often reflect no signal (-0dBm is spectacular but it really means no signal within the Android system). Now with the update it reflects up to -51dBm like it should for GSM/WCDMA with Android and doesn't drop to -0dBm anymore. This of course effected the bars, often dropping to no bars or 1. Now after it's been fixed, plenty of bars and proper -dBm readings.

Signal Strength Booster?

I get poor reception on my Incredible whereas my parents get great reception on their phone. A little googling and this popped up:
http://www.onlyincredible.com/incredible-booster.html
is this legit at all? i'm not a technical guy so I have no idea.
I call bull****. They used to sell these things for regular cellphones. They didn't work then, either.

I was thinking the same thing but trying to be hopeful ya know? I really need some signal boost. I average around -90 dBm
If you're desperate, it's not like $2 is a huge sacrifice for a likely useless piece of plastic. I don't know I usually get between 80-100dBm at my house and i have no complaints about the service... The bars don't necessarily tell the whole story. 85dBm is 5 bars on my 6bar signal meter, so keep in mind that bars don't necessarily tell how mcuh signal you have. With the stock 4 bar meter, I would never have 4 bars at my house; usually 1 or 2; sometimes 3.

I go by the dBm and just sitting my room I can go from -85 up to -120
I always thought that it would be normal for my dBm to be in the -60 range. Am I wrong or is -80 to -90 okay?
I get -91 to -106 in my room and I have good enough signal to do anything I want. Also my friend bought one of those for his Eris and thinks it actually hurt his reception but I can't imagine there's a difference with or without it

If you want something to boost your signal this is one of the only things I've found that will actually do it..... http://www.tigerdirect.com/applicat...CODE=GOOGLEBASE&cm_mmc_o=VRqCjC7BBTkwCjCECjCE
They are normally priced at $120 but can be had for $15. I bought one and currently use it in both my vehicle and home. It will boost the signal for me from around -105 dbm in my house to around -90 dbm, but I've seen it get as good as -81 dbm. I plan on buying another that way I don't have to keep moving it around.
They say it works within a 6 ft radius of the plug but I've found that you need to be a little closer than that to it.
-80dbm is the best signal possible. Also, cdma signal fluctuates. Don't expect it to stay at a consistent number. Unless you're having issues with dropped calls or slow data, I wouldn't spend another second concerning yourself over it.
Thanks for this... now would two of these work better then one?

Your head absorbs wireless signals.
So, use the speakerphone more often, or better yet, use a good quality Bluetooth ear piece so the phone can sit near a window still.

keep in mind that CDMA phones with VZW use two radio frequencies. one is voice, the other is data. so the "bars" and 3G doesn't do much to specify which of those two network connections its representing. my guess is that it's representing data strength, not voice.
-80dbm is the "best" signal strength i've ever seen a verizon wireless cell phone have. and that's based on other phones, such as blackberries, winmo, etc...i'm not sure if it gets any lower than that on CDMA networks. i know my WI-FI, when at the strongest, is usually -40 or -60 dbm.
for example, sitting at home my signal is -84 dBm, and that is pretty much full strength
also, the value we are discussing is how "loud" the signal is. take into consideration that network traffic will also impact service in varying ways.

[BUG] Signal Strenght Indicator

so here i got 3 Android phones
all sitting on the same spot
2 of them (SGS / XT720) shows 3 or 4 bars signal strength, but SNS only shows 1 bar, 2 at best.
however a quick test using 3G speedtest confirms the same download/upload speed as the 2 other phones.
and there's no problem calling even when it only shows 1 bar.
Can any body confirm this?
Go to settings > about phone > status and post the signal strength of each of them (should be in dBa). If they're the same, then ya either the SGS phones are overinflating their strength or the Nexus is reporting lower than it should.

The farther it is from 0 in the negative, the worse the strength is. The best strength I've ever seen on an android phone was -69. Worst is in the -100's so it looks like the Nexus is actually getting worse signal, not just reporting worse...maybe an antenna problem =(

quite the opposite, 0 is just a reference point, the farther from zero the better
Mine is -101 with 2 bars.
I'm not sure where you're getting this from, but you're saying -100dbm is better signal reception than -70dbm? If that's the case then the signal strength reporting is completely reversed... as I have full bars in my apartment and it shows -72dbm, and at work I have 1 to 0 bars and it says -101dbm. It's been like this for all of my phones.
Also speed tests at home give me 500k/s down and 50k/s up while at work I only get 60k/s down and 20k/s up...

It seems like the SNS is getting far worse ACTUAL reception than the other two phone.
-107 is very bad comparing to -97 and -84.
Are all 3 phones on the same carrier?

That's interesting as there is a huge difference between the SNS and the XT720.
-84dbm means very good reception and -107 is at the end of the workable spectrum (at -113 you basically can not place calls).
I am also noticing very bad reception on my SNS but i thought that it is due to T-Mobile's crappy network. i have no other T-mobile device to compare it with though so i start to wonder if its the Nexus S that has crappy reception or T-mobile.
Try to do more tests in other locations with the XT720 and the SNS and see if you always see such a huge difference when both devices are in exactly the same spot.
I am interested in your findings.
And as for your initial question, there is no bug in the signal indicator as -107db is very bad signal so the indicator is correct.
Okay please allow me to clear up some misunderstanding in this thread...
First of all, dBm is a logarithmic measure of signal strength with respect to 1mW. So, a smaller (i.e. more negative) reading means that you have lower signal strength.
Just to give an example: -50dBm is a much better signal than -100dBm.
Alright, so now let's move on to the next issue: You can't compare signal strength on two phones which are running on different networks. Why? It's possible that you have a strong signal from Fido and a weak signal from Wind, or vice-versa. If you want to compare the RF capabilities of two phones, you should make sure that they are connected to the same network and even the same cell (you can check the service menu to make sure that they are on the same cell).
And finally: The Settings>About Phone>Status is usually not a very accurate measure of signal strength, since they are rounded off to some pre-determined list of values (So for example, if it is jumping between -100 and -110, it might actually be jumping between -104 and -105). You should instead go to the phone's service menu (i.e. you type in some code into the keypad) where you will get an exact measurement.
My friend happened to have the XT720 while I have SNS, and we happened to be at a same location where my SNS can't maintain the connection (only able to connect at one room spot with 0 bars and unable to hear a thing due to choppy voice when I tried to check voicemail) and XT720 still got 2~3 bars anywhere in the room and able to make phone calls. We are both from same carrier. We left our phone on table side by side without touching it. So despite the bars on phone nor the signal number in setting menu, real life experience tells me XT720 does have better reception than SNS sadly D: I was embarassed that night when other friends laughted at my supposely better phone

Signal strength issue

I received my XT1053 T-Mobile Moto X this past Thursday and have been having signal issues since then.
People I've spoken to notified me that voice quality they heard was choppy, although I heard them fine.
I also noticed that I've been getting anywhere from -95 to -105 dBm, while my old phone and other phones receive -65 dBm to -75 dBm around the house.
These numbers are within my house and outside my house.
I'm running unrooted/all OTAs. Safe to assume something wrong with this particular phone?
Edit: When I set to network type to GPRS (2G), I'm getting a good -58 dBm. When I put it back on LTE I'm getting -100 dBm again.
So when I'm on LTE its just not connecting to the closer tower?

I've had the same problem on 3 moto x's. I think its only the tmo version that has this problem since no one else is complaining about it.
EDIT: Maybe not the same problem. Mine happens on HSPA and EDGE as well. It looses signal completely for hours.
The way an LTE signal strength is measured is not the same as 2G or 3G, that can explain quite a large db difference. Voice calls don't use LTE right now, your phone will switch back to HSPA/WCDMA/2G for voice.
Im on a dev edition verizon phone. Ive noticed Im getting average 103 dbm lte where as my other phones are at about 97. Voice 3G is about 85db which is good. Wondering if there isnt something wrong.

You're right. It does switch to HSPA+ and signal strength does increase back to -60 dBm while I'm talking.
So the phone shows 2 bars while I'm not on a call is simply because signal strength is measured differently and it doesn't take into account the different network type?
I wonder why two different people on two different days told me they were hearing me pretty choppy (I heard them fine) and I even had a dropped call, all within like 3 days of owning the phone, with pretty much no issues that I can remember with my previous phone (it was an HSPA+ phone).
I'm not sure what to do...

Maybe turn off voice privacy in phone settings.

I agree with the poster that LTE is just measured differently.
I have the N5, HTC One, and Moto X and they are both usually is the 90s or 100s for LTE. The X is usually 5-10 dbm better than either the N5 or One.
Best reception phone Ive had thus far :laugh:
