With the implementation of appropriate security measures receiving full attention in the water supply industry, many municipalities are faced with the challenge of not only monitoring their facilities through supervisory control and data acquisition (SCADA), but adding remote video surveillance and datalogging for security at remote sites. Most municipalities today already have SCADA systems in place, but those using radio communications as the primary backbone are limited to small bandwidths of less than 9600 bps. This leaves municipalities with only minimal bandwidth for datalogging retrieval and remote surveillance applications. Recently there has been an explosion in wireless products available on the market that will allow municipalities to leverage their existing infrastructure and available resources. These wireless products are based on the Ethernet communications media that is the underlying core in most office networking environments. This paper reviews fundamental concepts of wireless Ethernet communication, design considerations for implementation into new and existing municipal SCADA systems, benefits of using wireless Ethernet versus conventional radio systems, and its application with datalogging retrieval and video surveillance systems. Also discussed is an actual case study on a successful design and implementation project using a wireless Ethernet SCADA system in a large municipality. The case study examines integration into the Muncipality's existing SCADA communications infrastructure, design criteria used, benefits realized, and future IT development potential. Includes figures.
