City-Wide Wi-Fi Network

This is an 802.11b network designed for the City of Central Point law enforcement using Aironet and Cisco radios.  The project used solar for sites that were located without power.  There are 9 "repeater" and 1 root radio with a single hop to the police station.  IP based traffic was routed to the closest access point of the network as officers travelled throughout the city in their vehicles.  Cisco PCMCIA radio cards were installed in each MDC along with a CDPD card. 

Law Enforcement officers used the network to permit video surveillance from cameras located at key points within the city.  The speed of the network (2-11M)  versus the CDPD cards (up to 19.2K) in the in-car Mobile Data Computers permitted 5 - 15 fps of video and control of a PTZ camera from software running on the MDC's.  Access to local photos and other large files on servers located at the police station was made possible using the 802.11 Wi-Fi network.

Below are some photos of a "test" site as well as actual installations.
