A material medium, such as an optical fiber or electrical cable, is commonly used to carry services, such as telecommunications or energy service. The current invention identifies the following problems which may be encountered when monitoring a material medium. They are: (1) requiring a time and labor intensive investigation to find a fault, (2) needing a significant change in a current material medium infrastructure to support a monitoring effort, or (3) reducing available bandwidth in a material medium due to a monitoring device intruding into the material medium to send data. These problems are solved, in accordance with a feature of the current invention, by monitoring a material medium with at least one diagnostic sensor, and using an electromagnetic (EM) signal, such as radio frequency (RF), signal to wirelessly transmit the sensor data. The diagnostic sensor may measure the operational health of the material medium, or may measure local environmental conditions around the material medium. Using an EM signal, such as RF, to wirelessly transmit sensor data allows for a fast, low labor monitoring approach. Additionally, it avoids a need to either; (1) transfer the data by intruding into the monitored material medium, or (2) set up an independent material medium system to transfer the data. |
