Abstract: A marker for burying adjacent an underground structure such that a location of the underground structure can be identified from above a ground surface. The marker comprises a housing, a gimbal beacon retention device pivotally disposed within the housing, and a beacon device carried by the gimbal beacon retention device. The gimbal beacon retention device is structured and operable to orient the beacon device in a desired orientation relative to a ground surface regardless of the orientation of the housing relative to the ground surface.

Abstract: A system for determining and optimizing wireless network performance of a network having at least two access points comprises a plurality of wireless instruments configured to send, receive, and measure received wireless signals in a monitored area. The system further comprises a master controller in communication with the wireless instruments to form a distributed wireless network testing solution. The master controller is configured to send wireless signals to and receive wireless signals from the wireless instruments, measure the received wireless signals, and perform an analysis of the wireless signals to determine a radio frequency environment performance of the distributed wireless network based at least in part on the wireless signals.

Abstract: Methods of planning network provisioning that incorporate real-world measurements of signal quality into simulations of signal quality under alternative configurations. In one embodiment, the disclosure includes a method of determining placements for access points in a wireless network, comprising ingesting a floor plan for a deployment site, determining initial placements for the access points, determining placements for sensors, each sensor configured to wirelessly communicate with at least one access point, measuring a signal metric for each sensor, based at least in part on the measured signal metric for each of the sensors, simulating a projected coverage map for a plurality of alternate placements for the access points, determining an placement of the access points, and presenting, to a user, the placement of the plurality of access points.

Abstract: A system and method for generating a three dimensional graphic illustration of wireless communication system performance in a building.
