Abstract: A wireless communication device (e.g., operative within a wireless local area network (WLAN)) coordinates with another wireless communication device to determine which communication parameter(s) to use in at least one FTM frame exchange. In an example of operation, the wireless communication device includes a communication interface and a processor such that the processor receives, via the communication interface, a fine timing measurement (FTM) request frame from the other wireless communication device. The FTM request frame specifies at least one preferred communication parameter for the at least one FTM frame exchange. The processor then determines, based on the FTM request frame, information related to the at least one preferred communication parameter. The wireless communication device generates and transmits a response to the FTM request frame to the other wireless communication device that confirms or overrides the at least one preferred communication parameter.

Abstract: A method and telecommunications system for identifying uplink multiplexing resources of a multi-beam satellite that are usable in a land-based telecommunications system, e.g., a transmitting station for transmitting radio signals to a receiving station. The transmitting station or the receiving station being a base station having a range defining a coverage area. For a given uplink multiplexing resource, a maximum allowable interference level, with respect to the satellite, for radio-electric signals transmitted from the coverage area is estimated. A potential interference level of the transmitting station is estimated. The transmitting station determines the usability of the given uplink multiplexing resource by comparing the potential interference level with the maximum allowed interference level for the given uplink multiplexing resource.

Abstract: Systems and methods visualize a point to multi-point network, such as a network including Ethernet Ring Protection (ERP) using a visualization techniques used for point-to-point networks. For example, for a selected start and end node, intervening nodes may be identified and any protection rings also identified. A blocking port for each ring is identified and based thereon a path through the ring is identified. A trail between the start and end node is then generated using the current path through the protection rings. The trail may then be represented graphically. Unblocking of a blocked port of a ring may be detected and a new path through the ring may be determined and represented graphically. Status indicators may be included in the updated representation of the ring to indicate the presence of a failure condition.

Abstract: A system and method that utilize a learning system to maintain a set of geographical locations indicating an area where network data coverage is poor. When it is determined that a client device is moving towards such an area, the client is forced or instructed to switch to a lower delivery bitrate for video segments in order to force the client's Adaptive Bit Rate (ABR) playback buffer to fill itself with enough low-quality video segments to enable the client to cross the area without video playback interruption. Thus, the client mobile device may be preemptively forced to choose the lowest bitrate specified in a manifest file for the delivered video segments as the bitrate for downloading video segments when approaching the poor coverage area. Hence, the client device can maintain a minimum level of Quality of Service (QoS) when moving through network areas with poor data coverage.
