    Abstract: In an example embodiment, a method for determining backhaul channel assignments for multi-channel dual radio mesh nodes. The method comprises acquiring collision domain data for each access point of an associated mesh network. A cost function is calculated for each access point of the associated mesh network, the cost function assigning a weighted value for each access point in a collision domain based on a number of access points in the collision domain. Backhaul channel assignments for selected for each access point that minimizes the cost function.

    Abstract: 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 emobidment, 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.

    Abstract: Methods, apparatuses and systems directed to facilitating WLAM diagnostics and management using traffic stream metrics, In a data collection stage, according to one implementation of the present invention, localized uplink measurements are taken, at a wireless client associated with a wireless access point. During periodic intervals (e.g., every 5 seconds), the wireless client, in one implementation, transmits uplink measurement information, to the wi.rel.ess access point. The wireless access point may also take downlink measurements, which may also include one or more of the following metrics- observed latency, queuing delay, packet loss rate, and packet count information. The wireless access point, in one implementation, may aggregate and report the uplink and downlink metric information to a network management system. In a diagnostic stage, according to one implementation, a wireless network management module performs diagnostics of the WLAN based on the uplink and/or downlink metrics received from the wireless access point.
