Abstract: A system for effecting communication between first and second radio transceivers, comprises a communicator for effecting communication between the first and second radio transceivers over a first channel; a determiner for determining the distance between the transceivers, and for determining if the distance falls below a predetermined threshold; and a channel charger responsive to a positive determination, for effecting direct mode communication between the transceivers over a second channel.

Abstract: A system for interacting with a physical entity includes a user-wearable terminal and a mobile station. The user-wearable terminal is capable of automatically receiving a selection of a physical entity as at least a portion of a user wearing the terminal moves into proximity with the entity thereby moving the terminal into proximity with the entity. The terminal includes a first short-range communication element for receiving information from the entity at least partially over an air interface. In addition, the terminal includes a second short-range communication element for transferring input data to the mobile station at least partially over an air interface, where the input data is based upon the information related to the entity. The mobile station, upon receiving the input data, is capable of performing at least one action based upon the input data.
