Abstract
A network of wireless sensor nodes for wireless transmission to a base station is provided. The sensor nodes can provide real time streaming of data over separate frequency links that can all be received by the base station. The base station includes a receiver for receiving at multiple frequencies, error detection or correction, and analog outputs so sensor data can be provided to standard analysis systems that require analog signals as would be provided by wired sensors. The base station also provides an output indicating the presence of transmission error.
