Walkie-talkie with screen to show a list of other walkie-talkies within communication range
First Claim
1. A digital communication device comprising:
- means for transmitting identifying information as a first control signal periodically directly to other digital communication devices without utilizing fixed towers to re-transmit the first control signal;
means for receiving at least one second control signal as remote identifying information corresponding to the other digital communication devices within the communication range directly from the other digital communication devices without utilizing fixed towers to re-transmit the second control signal;
means for displaying information corresponding to at least a portion of the remote identifying information received from the other digital communication devices within the communication range, wherein the information is displayed as a selectable list to create a selected set of digital communication devices;
means for transmitting a voice communication as a voice signal to the selected set of digital communication devices while a transmit button is selected;
wherein the voice signal is received by the selected set of digital communication devices and the voice communication is output on a speaker of the selected set of digital communication devices.

Abstract
A device, method, and computer program product for identifying and communicating with digital communication devices within a communication range that includes a transmitter configured to transmit a control signal and a voice signal, a receiver configured to receive the control signal and the voice signal, a user interface unit having a display area, and a computational unit configured to control the transmitter to periodically transmit identifying information as the control signal. The control signal is received as remote identifying information by the other digital communication devices within the communication range. The remote identifying information is displayed on the display area of each of the digital communication devices receiving the control signal.
