Abstract: A network based positioning (NBP) system that improves the accuracy of wireless positioning systems by concurrently performing RTT ranging operations and associated TDOA operations to generate a number of difference measurement values from which the position of a station device (STA) can be determined using, for example, multilateration techniques. Because the RTT values and their corresponding TDOA values both include the turn-around time (TAT) of the STA, subtracting TDOA values from their corresponding RTT values generates difference measurement values that do not include such TAT values of the STA. In this manner, the STA position can be determined without estimating the STA's TAT.

Abstract: A user device receives packets from a base station. The user device may invoke decoding while the packet is still being received, based on the incomplete contents of a given packet. This “partial packet decoding” relies on the fact that the underlying information in the packet is encoded with redundancy (code rate less than one). If link quality is poor, the partial packet decoding is likely to be unsuccessful, i.e., to fail in its attempt to recover the underlying information. To avoid waste of power, the user device may be configured to apply one or more tests of link quality prior to invoking the partial packet decoding on a current packet.

Abstract: A physical Fiber Channel over Ethernet (FCoE) switch defines a multipath virtual FCoE switch to provide uninterrupted storage access between N_PORTs of an FCoE host and a Fiber Channel (FC) storage target, for example, in response to an F_PORT failure. Through the multipath virtual FCoE switch, the fabric is configured with multiple physical paths available between the FCoE hosts and FC targets. The multipath virtual FCoE switch is defined between or among multiple physical FCoE switches coupled to the Ethernet fabric. One of the F_PORTs is designated as being in the primary FCoE path, while any other F_PORTs sharing the virtual FCoE switch are reserved for standby paths in case the primary FCoE path is disabled. When a failure to a primary FCoE path is detected, a standby path is promoted to become a new primary FCoE path and subsequent traffic is routed in both directions through the new primary FCoE path.
