The D.W.A.F. existing grid system includes level transmitters and loggers, and field recorders, most of which require field technicians to visit the often far & remote sites to extract data & bring it back to the regional offices for processing. Almost all of these sites are in areas where there is no access to AC power. Laptops are used, & they are not well suited for use in sunlight, they consume power fast and take time to start up, connect up, download data,& shut down. This data is referred to as Historic Data, as station data for the previous two weeks or so is extracted at each visit. After two years of marketing a Swiss range of level equipment to the lower provinces - saw the problems being incurred by the D.W.A.F & decided to make the 'low powered' GSM communications system.
