Definition of Telemetry:
A technology for transferring data from a remote measurement location to a main operations or control center where the data can be viewed, processed and stored. Telemetry typically refers to wireless communications (i.e. using a radio system to implement the data link), but can also refer to data transfered over other media, such as a telephone or computer network or via an optical link.
