Abstract: A system and method including a local network formed of a plurality of identification devices that are operable to initiate communication with other identification devices to form the local network and are further operable to poll other identification devices, each identification device in wireless communication with at least one other identification device such that each identification device is capable of direct or indirect communication with other identification devices in the network. A gateway in wireless communication with the local network can allow direct or indirect communication between the gateway and each identification device in the local network. A central shipment controller can be configured to communicate with the gateway and is operable to receive data from and transmit data to the local network via the gateway. Each identification device can include a local device controller operable to switch the identification device between device operating states.
