In Windows Mobile, we can retrieve signal strength in two ways, one using TAPI and other using RIL. The TAPI function lineGetLineDevStatus is used to retrieve the signal strength of the current line. This function returns the details in LINEDEVSTATUS variable length structure. The dwSignalLevel member contains the signal strength in the range 0x00000000 to 0x0000FFFF.

The other method is to use the RIL function RIL_GetSignalQuality. This functon returns the signal strength in RILSIGNALQUALITY structure. The member nSignalStrength contains the signal strength. This link explains how to calculate the signal strength from the RILSIGNALQUALITY structure members.
