The federal park police utilized Alcatel-Lucent's LTE system operating on 700 MHz D-Block spectrum during the Washington, D.C. July 4 celebration this year on the National Mall. Their video-surveillance system is the first to operate on these waves, which the FCC currently has reserved for commercial auction.
The video backhaul system they have in place allows fixed surveillance equipment in the area to send high-definition video and thermal-imaging feeds to officials in a remote location. Their video-based technology, which included analytic capability, requires robust bandwidth.
Using 700 MHz frequencies allowed the base station to receive signal despite being out of the line of sight, something that would be impossible over a cellular connection because of the caliber of the cameras used. The FCC granted temporary authority for the federal park police to operate on the D-block spectrum for the event.
The technology services commander for the U.S. Park Police attributes the success of the network to having dedicated spectrum that did not have to be shared with commercial users.
