Abstract
A communication device is presented that includes a receiver operatively coupled to a processor. The receiver receives communication data from other communication devices. The device also includes a speaker operatively coupled to the processor. The speaker is configured to output a sound wave based on an output from the processor. The processor determines a distance from another communication device transmitting communication data to the communication device. A volume of the sound wave is reduced in proportion to the distance between the communication device and the other device.
Claims20
A communication device, comprising:
- a receiver operatively coupled to a processor, wherein the receiver receives communication data from other communication devices;
- a speaker operatively coupled to the processor, the speaker configured to output a sound wave based on an output from the processor;
- wherein the processor determines a distance from another communication device transmitting communication data to the communication device;
- and
- wherein a volume of the sound wave is reduced in proportion to the distance between the communication device and the other device.
A method of switching between communication networks, the method comprising:
- operating a communication device in a first communication network with a first group of devices;
- detecting that a first distance between the communication device and the first group of devices is increasing;
- adjusting a first volume associating with received communication from the first group of devices to zero after a threshold distance is reached;
- detecting a second group of devices, in a second communication network, within the threshold distance;
- joining the second communication network;
- and
- increasing a second volume associated with received communication from the second group of devices as a second distance between the communication device and the second group of devices decreases.
