Abstract
The present invention provides methods, devices, and systems for creating an ad-hoc conference station from speakers on a plurality of mobile communication devices. The ad-hoc conference station can cancel the echo of any incoming audio for all of the communication devices. This feature may be achieved by employing a master/slave configuration for the communication devices within a common area.
