Method for transmitting a digitized message of little information depth
First Claim
1. A method for radio transmitting a digitized message of little depth of information in a power-saving manner by transmitters with limited power reserves in an environment of periodic radio interference sources generating periodic disturbances, wherein the method comprises the steps of:
- transmitting the digitized message of little depth of information in each of a transmitting pulse;
for each said transmitting pulse, transmitting the digitized message of little depth of information with a data transmission rate which is at least of such a magnitude that a length of the transmitting pulse in time is shorter than a length in time between the periodic disturbances; and
wherein a message of a same content is transmitted at least a second time, a period of time between the transmitting pulses of the message of the same content being one of predetermined and randomly selected; and
wherein the period of time between the transmitting pulses of the message of the same content differs from integral multiples of interference signal periods of the periodic disturbances, within a range of the signal pulses.

Abstract
A method for transmitting a digital message of little depth of information such as, e.g. measured values of sensors by transmitters, for example wireless sensors with little power reserves, in which the data are transmitted in pulses and each transmitted pulse transmits the data with a data transmission rate of more than 100 kbit per second. To further optimize the transmission method, the information content of an individual transmitted pulse is increased by time- or position-coding.
