Claim 0:
1. A method for filtering out signals, the method comprising:
extracting with an agent channel state information from a chipset operating according to a defined wireless standard of a wireless access point associated with an active sensing area where the wireless access point receives wireless signals via a wireless link according to the defined wireless standard from a wireless device associated with the active sensing area;
establishing a channel matrix based upon the extracted channel state information comprising channel state information of different frequency sub-bands of the wireless link according to the defined wireless standard in a first dimension of the channel matrix and different samples or packets in a second dimension of the channel matrix;
filtering with the agent the established channel matrix by applying a low-pass filter and a notch filter to the established channel matrix wherein the low-pass filter filters out a predetermined type of unwanted high frequency signals from the established channel matrix and the notch filter filters out a predetermined type of unwanted low frequency signals from the established channel matrix;
establishing in dependence upon the filtered established channel matrix and a plurality of profiles a profile of the plurality of profiles to associate with the sensing area where each profile of the plurality of profiles comprises a channel state information profile associated with one of an activity, an object, an individual and a biometric associated with or within the sensing area.
