WIRELESS COMMUNICATION SYSTEM |
摘要 |
<p>In a wireless communication system, an approach determination section determines whether a portable device is inside of a nearby area of one of a plurality of transmitting antennas transmitting a primary signal. When the approach determination section determines that the portable device is inside of the nearby area, a transmission control section changes a driving voltage of another one of the transmitting antennas disposed outside of the nearby area, such that a communication area of the another one of the transmitting antennas is increased to encompass the nearby area of the one of the transmitting antennas, and the primary signal is retransmitted from the another one of the transmitting antennas.</p> |
