If a lotof units need to be controlled, 2-wire phone line and connectorswill probably a lot cheaper. Of course wireless may be essentialfor roving units.

The brands you want to look at depend uponthe application. The on-farm equipment is generally verydifferent from that used for canals. If you are interested in SCADA (Supervisory Control and DataAcquisition) for irrigation projects, we offer short courses onthe topic and have the latest equipment set up at our WaterDelivery Facility. The on-farm is a big topic, but various techniques include usingpager signals, spread-spectrum radio, regular types of radio,infrared, etc. Charles M.
