BT Whole Home (Wholehome) WIFI >>> meaning of "Signal Strength"

The Whole Home App shows a signal strength 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The BT Whole Home App shows a signal strength for the wireless-only discs. My readings vary over time but one indicates -77 and the other -74 as I write.

 

Do these readings have a particular relevance, say in terms of dBW, or are they just relative numbers?

 

Are my readings good or poor?

Hi,

 

Are you referring to signal strength under disc details or device information?

Hello

 

I am referring to the Disk Details in the App.

Sorry - I didn't see the rest of your message the first time.

 

The readings refer to the signal in dBm.

 

Anything between -50 and -80 is ideal - this number influences whether the disc shows as "excellent", "good" or "poor".

Re: BT Whole Home (Wholehome) WIFI >>> meaning of "Signal Strength"

Thank you, Dan-O, I appreciate your clear response.

 

I now understand the numbers are dBm. 

 

I seem through early experimentation to achieve numbers in the -70 to -79 dBm region unless I have perfect line of sight between two transceivers in which case I can get figures of around about -55 dBm.

 

Now that I understand the boundaries (and with the addition of a power point in the hall), I may be able to contrive line of sight communications between transceivers.

 

Regards, Sterling

Hi Dan O,

Noting that your reply applies only to the discs - does the same range apply to the numbers shown in the App for connected devices?

Kind regards,

Graham
