When should Cellular Data Networks be considered for SCADA applications?
Use of Cellular technologies for SCADA may be considered when wide area coverage is required and the cost of alternative technologies (Private Radio systems, Satellite, etc…) is uneconomical. Although Cellular communications is available throughout many parts of North America and many remote sites are covered by Cellular, there are still many areas where it is not available due to remoteness and lack of customer base. When considering the Cellular SCADA communications option, check with your local Celllular Provider to see if Cellular data service is available in your area. Cellular communications may be employed as the link to all remote sites or as a main link to a hub site, with private radio system used to extend out to nearby sites. What technologies are available for SCADA communications over Cellular? Technologies for SCADA communications over cellular include: • ● Circuit switched data • ● Packet data. Circuit Switched data is essentially dialup modem communications except th
