Patent ID: 8102796

Claim:
A wireless data communication system comprising: a master device comprising wireless data communication means for transmitting and receiving data packets between the master device and at least one slave device using a synchronized data communication protocol, at least one slave device comprising wireless data communication means for transmitting and receiving data packets between the master device and at least one slave device using the synchronized data communication protocol, means for monitoring data traffic of a communication channel, from the slave device(s) to the master device, to control the traffic in the channel itself, the means defining a first time period between consecutive packets to be transmitted in the master device, defining a second time period for calculating the number of packets received by the master device during the second time period, calculating the number of data packets received by the master device in the predetermined second time period, wherein when the calculated number of packets is smaller than a first threshold value the first time period is decreased, and when the calculated number of packets is larger than a second threshold value the first time period is increased, wherein monitoring data traffic of the communication channel, from the slave device(s) to the master device, to control the traffic in the channel itself reduces the average power consumption in a wireless data communication system, and wherein said monitoring of data traffic reduces data transfer variation and improves consistent data transfer between the master device and the slave device(s).
