One-way transmission of measurements at a distance from the measuring instrument✓Bonne réponse
Two-way transmissions in excess of 1000 feet
Two-way transmissions of data
One-way transmission that initiates, modifies, or terminates the functions of a device at a distance
Explication
Telemetry is a one-way transmission of measurements at a distance from the measuring instrument. The choice describing a one-way transmission that starts, changes or stops a distant device defines telecommand instead, and nothing about telemetry is two-way or distance-limited.
