Success Story Excerpt: Louisville's Waterfront Park

Louisville’s picturesque 85-acre Waterfront Park became the site of “mob violence” on the evening of Saturday, March 22, 2014. According to the FBI, in an article published by the Courier-Journal, “mob violence” occurred when a gang of middle school students went to Waterfront Park to fight another local gang. City leaders needed to move quickly to increase security and help reduce safety concerns in the park in advance of the city’s Thunder Over Louisville air show and fireworks display scheduled for April 12, 2014. “We were tasked with installing 28 cameras in the 85 acre park in less than two week time due to the upcoming major event which would have over 600,000 attendees,” explained Chris Seidt, Network Supervisor at Louisville Metro Government. With the cameras installed throughout the park, network connectivity was enabled quickly and easily using the EnGenius wireless access points and bridges. “The ENH700s are installed on the buildings with the fiber and switches, and the ENH500s are mounted with the cameras and are pointed back to the ENH700s,” explained Seidt. “The EnGenius devices were simple to configure, easy to mount and install, and provide ample bandwidth for the high definition cameras we’re deploying.” According to Seidt, thanks to the easy installation and configuration of the EnGenius products, Waterfront Park’s new video surveillance solution was installed on schedule and is working well.

Beamforming

Beamforming or spatial filtering is a signal processing technique used in sensor arrays for directional signal transmission or reception.This is achieved by combining elements in a phased array in such a way that signals at particular angles experience constructive interference while others experience destructive interference. Beamforming can be used at both the transmitting and receiving ends in order to achieve spatial selectivity. The improvement compared with omnidirectional reception/transmission is known as the directivity of the element. Beamforming can be used for radio or sound waves. It has found numerous applications in radar, sonar, seismology, wireless communications, radio astronomy, acoustics, and biomedicine. Adaptive beamforming is used to detect and estimate the signal-of-interest at the output of a sensor array by means of optimal (e.g., least-squares) spatial filtering and interference rejection.
