Subspace transceiver

A subspace transceiver, also known as a subspace comm, subspace radio, hypertransceiver, subspace vox, or wide-band radio receptor, was a standard device used for instantaneous, faster-than-light communications between nearby systems. Similar to its shorter-ranged cousin, the comlink, subspace transceivers relied on energy to broadcast signals. Starships carried these units to broadcast distress signals and other important messages. They used subspace as the communications medium. The subspace transceiver of an Imperial Star Destroyer had a range of 100 light-years.
