How to get mobile signal strength in dBm?

There is an API called telephony_network_get_rssi, but this will return "relative strength" which is not very useful. Is there a mapping to convert this relative strength to an absolute value, e.g. in dbM? Or is there any other API that provides that information?

As a comparison in Android similarly name function returns signal strength in ASU and RSCP. Both are standards and convertible directly to dBm.

Platform: Tizen 2.3.2, Gear S3.

May be you are refering to these values, right?

I do agree with you, this is not as useful as 'representation in strength measuring units'. I have found some relation with units here in Samsung Developers: Network API, though it's for wi-fi signal strength in Tizen TV.

 

function: getWiFiSignalStrengthLevel

Hi Armaan,

Thank you. Yes I was referring to those values, which aren't very useful for most purposes (other than for displaying "signal bars" on the UI). Thank you the link to Samsung TV link, although I have to say that I doubt the relationships are the same or similar (mobile signals by definition are usually much weaker than Wifi).

I wonder if someone from Samsung can provide us with some answers.

Hi James B

I'm in charge of Telephony Framework in Tizen Platform.

As you mentioned, currently there is no API for signal dBm info.

Because dBm range and value of signal strength depends on Serving Network type, so Telephony framework serves the RSSI level instead of absolute dBm value.

Until now we think RSSI level info is more useful than the absolute dBm value for user.

However, your suggestion  is worthful opinion for improving Platform functionality.

So, we will condiser and discuss whether new API for absolute dBm info should be added  or not.

Thank you Shinhui.

When you make this function available, will this be ported back to Gear S3?

Hello James B

 

If this function is avaliable on public release of Tizen platform,

We can not confirm whether this is ported back to Gear S3 or not.

As you know, for applying any platform change on product device, there should be S/W update decision policy and release.

So To be applied any platform change to Gear S3, It should be decided  and handled by product relevant division.

Sorry for not being any certain about porting back on Gear S3 now.
