Each automatic station has an area of influence of 1250 meters. This means that any measurement done within 1250 meters of a station should be the same as the measurement done by the station itself. The total area of the district is 80,000,000 meters squared.
Stations have the ability to collect data at different time intervals.
They can be set to collect data every 5 minute or at every 60 minutes or every four hour. Data is transmitted from the stations via cellular phone to a central computer. More data means longer phone calls. Each byte, on the other hand, is made out of eight bits of information. Our cell phones and modem connections can transmit 4800 bits per second.
