Abstract

One example described herein includes a launchable communications device. The device includes an electronic payload comprising a communication system configured to receive a first communications signal and to transmit a second communications signal along a communications path between a first communication station and a second communication station. The device also includes deployment equipment configured to deploy the launchable communications device and to sustain a deployment state of the launchable communications device with respect to a predetermined operational environment. The device further includes a rigid housing configured to substantially enclose the electronic payload and the conveyance equipment prior to and during at least a portion of deployment of the launchable communications device to the predetermined operational environment.
