In one wastewater treatment plant, wireless technology was used to establish a simplified network structure, as shown in the diagram. Real-time monitoring was possible due to fast, reliable Ethernet between the remote control center and the different water treatment stations. At various stations, the AWK-1200-AP or AWK-1200-AC was installed, forming a wireless communication network that could deliver data synchronously or in batches. For better range and signal quality, antennas were installed at the highest point possible. No other infrastructure change was required. Since AWK-1200 products are IP68/67-certified, they can easily withstand the rough elements of outdoor environments, such as rain, dust, and extreme temperatures. With the wireless network in place, field engineers could now check the status of each station from anywhere on the plant, using their PDA or mobile phone.
Wireless systems provide significant advantages over wired systems for certain applications, particularly those involving long-distance communication. These advantages are particularly applicable to water distribution systems and wastewater collections systems. For such applications, wireless networking reduces installation costs, adds flexibility, improves data collection, and potentially improves site security.
