Patent ID: 8457174

Claim:
A method for wirelessly transmitting management data without cables in a data center, the method comprising: obtaining management data at a device in the data center; generating a wireless management data signal from the management data, which 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 s 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; 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 an other device.
