Abstract:
1. A device configured to wirelessly transmit management data to an other device without cables in a data center, where the device and the other device run in the data center, the device comprising: memory for storing a program; and a processor functionally coupled to the memory, the processor being responsive to computer-executable instructions contained in the program and operative for: obtaining management data at the device in the data center; generating a wireless management data signal from the management data; configuring the wireless management data signal to be transmitted at frequencies matching an ambient electromagnetic noise emitted by the data center, such that the wireless management data signal is masked in the ambient electromagnetic noise emitted by the data center; and wirelessly transmitting the wireless management data signal to the other device; wherein generating the wireless management data signal from the management data comprises: modulating the management data on a plurality of target frequencies for carrier frequencies of the management data, wherein the plurality of target frequencies are within a spectrum of the ambient electromagnetic noise of the data center; spreading the management data on the plurality of target frequencies for carrier frequencies to have a larger bandwidth than the management data, while still maintaining the management data on the plurality of target frequencies for carrier frequencies within the spectrum of the ambient electromagnetic noise of the data center; randomly selecting an order in which the plurality of target frequencies for carrier frequencies are to be transmitted; and clipping an amplitude of the management data on the plurality of target frequencies for carrier frequencies to be within a regulated class.
