摘要： Methods, apparatuses and systems directed to providing location services in a wireless network. According to one implementation of the present invention, the wireless network infrastructure provides high-accuracy location information via location services to wireless clients. In one embodiment, during an advertisement phase, a location server provides a list of available location services to wireless clients via a central controller. In another embodiment, during a presentation phase, a driver of the wireless client presents the available location services to one or more applications of the wireless client. In another embodiment, during a request phase, the driver transmits a location service request to the central controller, which passes the location service request to the location server.

摘要： Measured data, such as WLAN data, are received. The measured data are compared with expected data, such as expected WLAN data. Expected WLAN data can be generated from various sources, for example floor plan data and access point data (e.g., quantity, placement, and/or configuration). Based on such measured data, WLAN features can be changed, such as floor plan and/or access point data (e.g., quantity, placement, and/or configuration).
