1. A device for wireless communication comprising:
- a. a transmitting portion including one or more antennas characterized by one or more radiation patterns, each radiation pattern defining dependence of intensity of electromagnetic radiation generated by an antenna on direction and distance from the transmitting portion in correspondence with power supplied to the antenna;
b. a sensor system configured for determining a relative orientation between the transmitting portion and a reference orientation, the reference orientation indicative of one or more predetermined axes external to the device;
c. a control system operatively coupled to the transmitting portion and to the sensor system, wherein the control system is configured to selectively control the power supplied to the one or more antennas in correspondence with the determined relative orientation between the transmitting portion and the reference orientation; and
d. an interconnect system configured to interconnect the device to a host computer system, said device configured as a peripheral device,wherein predetermined control of intensity of electromagnetic radiation emitted from the transmitting portion is provided in predetermined directions.
