ABSTRACT:
A conference call feature is offered for use with spread spectrum cordless communication systems. The conference call feature is achieved through the alternate use of redundant communication resources by units on the conference call. The redundant communication resources in spread spectrum communication systems transmit duplicate copies of messages in high noise environments. In residential environments, noise tends to be less of a problem and can, hence, be used to support a conference call feature.
