    • Base stations for · ΜΙΜΟ wireless systems embodying efficient channel estimation techniques. One illustrative embodiment includes: an array of multiple antennas to exchange uplink and downlink signals with spatially-dlstributed user terminals; multiple: transmit chains, each coupled to one of the multiple antennas by a respective transceiver that also couples that antenna to a respective one of multiple receive chains; and a controller, Each of the receive chains opportunistically derives estimated uplink channel response coefficients from packet headers In the wireless uplink signals,, and the controller determines a steering transform based at least in part on the estimated channel response coefficients. The transmit chains apply the steering transform to spatially-distinct downlink signals to produce antenna-specific downlink signals for each antenna in the array. Another illustrative embodiment determines, based at least in part on the estimated channel response coefficients,; a mobility indicator for each user terminal, and, based on the mobility indicators, schedules at least one action.

    • A quick release strap tube mount is for mounting a strap tube to an equipment item. The strap tube has a notch formed therein and provides a channel for conveyance of strapping material. The mount includes a housing defining a strap tube channel. At least one locking arm is mounted to and disposed within the housing. The locking arm is disposed outside of the strap tube channel. A locking hub is operably connected to the locking arm and extends into the strap tube channel. The locking hub engages the strap tube at the notch. The locking arm and hub are pivotable relative to the housing between a latched position and a release position. A biasing element is coupled to the locking arm and the housing to bias the locking arm into the latched position and a release member is operably connected to the locking arm to move the locking arm and hub from the latched position to the release position to release the strap tube.
