Assignee: SR TECHNOLOGIES, INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 10:
11. A monitoring station configurable to monitor a communication between a first wireless device and a second wireless device, the monitoring station comprising:
a transceiver configured to:
receive a packet from the first wireless device, the packet being addressed to the second wireless device;
transmit a blocking signal when the received packet meets at least one criterion of one packet that is to be blocked, the blocking signal causing:
an interference with a reception, at the second wireless device, of at least one field of the received packet;
the second wireless device to determine that the packet has not been successfully received at the second wireless device based on the interference with the reception of the at least one field;
the second wireless device to avoid transmitting a first acknowledgement packet, in response to determining that the packet has not been successfully received at the second wireless device;

transmit, from the monitoring station to the first wireless device, a second acknowledgement packet including information indicating a successful reception of the packet by the second wireless device, the second acknowledgement packet being transmitted at a time after the termination of the transmission of the blocking signal, the transmitted second acknowledgement packet triggering the first wireless device to determine that the packet was successfully received by the second wireless device and to avoid re-transmission of the packet; and

processing circuitry in communication with the transceiver, the processing circuitry being configured to:
determine whether the received packet meets the at least one criterion of the one packet that is to be blocked.
