A wireless telemetry system includes many radio transmitters using frequency-hopping carriers for intermittently transmitting very short messages indicative of status of stimuli associated with the transmitters. The transmitters can transmit independently of any receiver for receiving from the transmitters and independently of each other. Transmission frequency and time between transmissions are varied according to time-frequency patterns that can be different for each transmitter. Urgent messages, such as alarms, are transmitted at transmission opportunities at intervals smaller than routine transmissions. The transmission opportunities are also according to a time-frequency pattern. Power-up transmissions carry information about future transmission opportunities and/or routine transmissions. Power-up transmissions can also carry information about time-frequency pattern for controlling routine transmissions and/or transmission opportunities. The system comprises a receiver for receiving from the transmitters. The receiver holds data indicative of time and frequency of future routine transmissions and transmission opportunities simultaneously for each of the transmitters.
