Claim Text:
1. A remotely deployed two way audio communication system, comprising: a plurality of observation devices deployed in, and distributed in a region, each observation device including a wireless local area transceiver, an audio processor coupled to the wireless local area transceiver, and a microphone and a speaker that are each coupled to the audio processor, wherein each of the plurality of observation devices are acoustically calibrated for audio magnitude and audio phase with respect to each other, and wherein the observation devices form a wireless mesh network where each observation device communicates in the wireless mesh network using its respective wireless local area transceiver; and a gateway device co-located in the region with the plurality of observation devices, and having a wireless local area transceiver that communicates with the plurality of observation devices through the wireless mesh network, and further including a wireless wide area transceiver in communication with a wide area station located remotely from the region, wherein the gateway device communicates audio signals received from the observation devices to the wide area station, and from the wide area station via the wireless wide area transceiver to the plurality of observation devices via the wireless mesh network to be played by at least some of the observation devices to acoustically combine additively at a selected location in the region.
