1. A method of sensing conditions of a wireless network, comprising:

  • receiving, by a network sensor of a plurality of coordinated network sensors within the wireless network a packet transmitted to an access point;

    determining, by the network sensor, a time stamp for the packet for synchronization of packet transmission; and

    determining, by the network sensor, whether to transmit at least a representation of the received packet transmitted to the access point to a service engine of the wireless network based on at least the time stamp of the packet plus or minus a statistical confidence interval of time synchronization between the plurality of coordinated network sensors and on an internal state of the network sensor; and

    wherein;

    the internal state of the network sensor comprises a data structure that stores a subsampling of previously input transmitter addresses active in the wireless network during a time window immediately prior to receiving the packet; and

    determining whether to transmit the at least the representation of the packet comprises;

    determining whether a transmitter address of the packet is different than any transmitter address of any other packet evaluated within a last T1 seconds of the time window or whether the transmitter address of the packet matches a transmitter address of another packet that is different than any transmitter address within a last T2 seconds of the time window.
