Abstract: Systems and methods are described for determining latency in a communication network. A non-IP protocol physical interface may be implemented at an access node. The physical interface may be configured to receive a simulated wireless device that mimics a radio-frequency interface. Delay data associated with segmented portions of a backhaul of the communication network may be measured at a base band unit (BBU) of the access node using the simulated wireless device. At least one segment of the backhaul may be isolated based on the measured delay data associated with the segmented portions.

Abstract: A wireless mesh network is configured. Each node is configured to function as either a gateway node or a relay node. To configure itself as a gateway node, an access node selects an SSID for each of its wireless interfaces that indicates it is an access node. When a relay access node is configuring itself, it scans for the SSIDs of available networks. The SSIDs of the mesh network are selected to indicate the number of other access points between a given access node and a direct wired connection (which is zero in the case of a gateway node.) The relay access node connects to the network having an SSID that indicates the fewest number of hops between itself and a direct wired connection. The SSID that is broadcast by the relay access node indicates the number of other access points between itself and a direct wired connection.

Abstract: A method of transcoding web images. The method comprises determining a mean opinion score (MoS) for a test source digital image, transcoding the test source digital image to a test derived digital image, and determining a MoS for the test derived digital image presented on a standard display. The method further comprises receiving a source digital image by a server computer, where the source digital image is requested by a device for presentation on a target display, transcoding the source digital image to a derived digital image by a transcoding application executed by the server computer, determining an estimated MoS for the derived digital image based on the MoS for the test source digital image, based on the MoS for the test derived digital image, and based on differences between the standard display and the target display, and changing a parameter of the transcoding application based on the estimated MoS.

Abstract: In systems and methods of managing network selection for a wireless device, a record is sent to a wireless device in communication with a first communication network, the record comprising a plurality locations where other wireless devices have changed from communicating with the first communication network to communicating with a second communication network and a plurality of timer durations. At least one of the plurality of timer durations is associated with one of the plurality of locations. It is determined that the wireless device has entered one of the plurality of locations, and a timer is started using the at least one timer duration associated with the entered location. Before the at least one timer expires, the wireless device is prevented from changing from communicating with the first communication network to communicating with the second communication network.
