A communication device and method therein for obtaining a position of the communication device are disclosed. The communication device operates in a wireless communication environment which comprises wireless communication networks comprising one or more wider range Access Points and Localized Wireless Networks (LWN) comprising one or more LWN Access Points. The communication device determines if it is in an LWN, when it in an LWN, it receives its position from an LWN AP in the LWN. Then it measures and records a first set of Received Signal Strength values of one or more wider range Access Points. When it is not in an LWN, it measures and records a second set of RSS values of the one or more wider range APs, and scales each of the second set of RSS values by a scaling factor calculated for each of the one or more wider range APs based on the first set of RSS values and reference RSS values of the one or more wider range APs. And then the communication device calculates the position based on the scaled RSS values. |
