My understanding is that the higher your phone signals dBm (decibel-milliwatts) are i.e. closer to zero the better. Also that if your ASU (Arbitrary Strength Unit) is higher the better and that both these measurements of phone signal strength are more accurate than the signal bars on your phone. Is this correct?
I am doing some testing trying to compare LTE to 3G on my phone.
With LTE selected I get -108 dBm and 32 ASU (Network setting: LTE/WCDMA/GSM)
With HSDPA selected I get -87 dBm and 13 ASU (Network setting: WCDMA/GSM)
What I thought was that a higher (i.e. closer to zero) dBm would result in a higher ASU but the above figures do not confirm this.
The phone signals in my area are generally not wonderful and you should be on 3G and not GSM to properly receive phone calls in most areas.
Ultimately I am trying to figure out whether having a weak LTE is better than a strong 3G especially for VoIP calls. Also my understanding is that if you are using LTE or 3G for mobile data, if you make a phone call it will automatically be on GSM. Is this correct?
