Hello All -
However, the app I am developing (an enterprise app for determining cellular
coverage in a given location) seems to be limited by the SNAPI abstraction.
That is, Microsoft.WindowsMobile.Status.SystemProperty.PhoneSignalStrength
gives me "phone signal strength, expressed as a percentage of full strength"
but that value is not actually useful in technical applications. (It's kinda
like if your car gave you a percentage as your speed.) Can anyone help
answer any of these questions:
What is the actual RSSI value? A percentage such as that returned by
PhoneSignalStrength is a fraction. In this case, it is probably the current
RSSI divided by the maximum RSSI. I need to know the current RSSI - either
directly or by deriving from the percentage and maximum RSSI. Does anyone
know how to access these values?
Is there a way to get the current Bit Error Rate (BER)? Many modems offer
this in response to an AT command. It would be almost as helpful as RSSI.
For that matter, does anyone know of a way to send AT commands directly to
the modem and get the response? The modems have a ton of troubleshooting
tools (that admittedly may be modem-specific) that would be great to have in
a mobile device that relies on said modem.
Thanks for any insights or advice.
- Hank
