Claim:
A wireless security system, the system comprising: a network hub that wirelessly sends and receives message packets; at least one security sensor that wirelessly sends and receives message packets to and from the network hub; and a packet router that monitors packet communications from the network hub to the at least one sensor and from the at least one security sensor to the network hub, the packet router configured to determine when a first type of communication failure occurs, the first type of communication failure being a failure of a message packet from the at least one security sensor to be received by the network hub, and send a first message packet that is the same as the message packet from the at least one sensor to the network hub if the first type of communication failure occurs; and determine when a second type of communication failure occurs, the second type of communication failure being a failure of a message packet from the network hub to be received by the at least one security sensor, and send a second message packet that is the same as the message packet from the network hub to the at least one security sensor if the second type of communication failure occurs.
