What's everyone's opinions on there radios? I came from the charge and a s2 shortly... My note comes in everywhere my charge didn't after a few days of use...I hear lotsa talk about how they suck...they must not have a note cause they have improved alot in my opinion...

Better than my HTC Evo, but not as good as my friends Razr HD MAXX and iPhone 5. But, I was originally on EVDO and now on GSM. That might make a difference too.

My Note and Note 2 have consistently 5-10dBm weaker signal than my Motorola Defy, on both at&t and T-Mo.

I have no technical data but I have had no issues since my move from the Motorola Razr Maxx. I was worried as I work on the fringe of reception, but is well with my reception.

Sadly mine has been a lot weaker then my S3 or Iphone 4s. Used to get 3-4 bars easily and now getting 2-3 at work. Still wouldn't trade my N2 though.

"Number of bars" is arbitrary, and relative to a given phone, in regards to actual signal strength in dBm readings. I got "3 bars" with my at&t Note 1, when dBm was at -97 to -103...however calls start to fail, and data fails to connect at these levels. I think 3 out of 5 bars is a bit overstated in this case.

Well I notice with 2 bars, some calls do not go through and when I have three bars I don't seem to miss any. 3 bars showing -102dBm 40 asu. I'll have to see what it shows with 2 bars.

Roger that.

Not as good as my former Motorola Photon but better than the S3. It's one of the reasons I traded up to the Note 2. I'm just glad it was an improvement.

My experience has been interesting. My s3 had better dbm, but worse real life reception.

My note 2 has worse dbm than the s3, but phenomenal reception. I not only can get a signal, but can place good quality calls in my underground basement and the hospital. The s3 was dead in most of these areas. Interestingly, the dbm are worse, but the call quality is better. Hard to explain, unless the antennae is much better in the note 2.

Got this off another forum. Would this be correct?

dBm Signal Strength
-105 to -100 = Really bad
-99 to -90 = Not great
-89 to -80 = Pretty good
-79 to -65 = Good
Over -65 = Excellent

FWIW, I generally see increased battery drain below -90dBm, and connection issues start at the -101/-103 level. YMMV.

All I know is it puts my charge to shame..I don't care about numbers..I know where it works now and it didn't before...

That seems according to old RSSI signal measurement standard. That doesn't apply to LTE phones with Android 4.x, OS. But it was correct for 3G android phones with OS up to 2.3.X.

Simply put, subtract about 15dbm to above numbers for RSRP signal reporting on LTE phones. -120dbm is about where LTE signal starts dropping, which is in line with my experience.

This post on rootzwiki explains that well though it's a bit length. But it's worth of reading to understand how signal is reported on phone.

Lucky you. .."my" LTE Note fails to load web pages at -105dBm, or "2 bars". Even loading these forums via Tapatalk.

The original Note was released with GB. Was that -105dbm reported from Gingerbread or ICS? If GB, that's roughly equivalent to -120dbm on ICS or JB.

I posted above things just to point out the difference in dbm reporting with different OS, radios. Still a lot of folks don't realize this and wrongly compare 3G signal strength of old phone to 4G strength of new phone.

colnago · Jan 23, 2013

I had both GB, and ICS on my Note 1...same behavior at same dBm levels, for both GSM, and LTE. Also see same behaviors, at the same dBm levels, on my T-Mo, HSPA+, Note 2.

I'm with ctxx24 on this .... For a year and a half I had Samsung Droid Charge .... Constantly getting lousy, weak WiFi system .... Now my Galaxy Note II gets strong WiFi reception throughout my house ... Last week used it on Amtrak and got good WiFi onboard the train .... Just a world of difference, very very pleased with Note II's radio.
