Abstract

A novel wireless data communication topology collecting and transmitting data from various sensors and other data sources in a facility. The topology includes serial data modems, serial to Ethernet converters, Ethernet to General Purpose Interface Bus (GPIB) converters, wireless data transmitters and wireless Ethernet radios, e.g., wireless bridges. These data transmission devices transmit data collected from sensors, test instruments and other data generators that monitor a facility. The transmitted data is uploaded to data collection computer systems that may be networked using a LAN (local area network) an intranet and/or internet.
