Wireless terminals including smart antenna systems having multiple antennas
First Claim
1. A wireless communication device, comprising:
- a transceiver configured for communication using multiple communication modes, the transceiver comprising a transmitter and a receiver;
a plurality of antennas coupled to the transceiver, the plurality of antennas including a first antenna and a second antenna, wherein the multiple communication modes include a multiple input multiple output (“
MIMO”
) mode and a single antenna receive mode; and
a control circuit configured to detect selection of the single antenna receive mode as an active one of the multiple communication modes, to detect selection of the MIMO mode as the active one of the multiple communication modes, to configure at least the first antenna to transmit a signal responsive to detection of the selection of the MIMO mode, and to automatically alter a configuration of the plurality of antennas and transceiver by configuring the first antenna as a transmit only antenna and the second antenna as a receive only antenna responsive to detection of the selection of the single antenna receive mode.

Abstract
A wireless communication device includes a transceiver configured for communication using multiple communication modes, the transceiver comprising a transmitter and a receiver. A plurality of antennas is coupled to the transceiver. The plurality of antennas includes a first antenna and a second antenna. The multiple communication modes include a multiple input multiple output (“MIMO”) mode and a single antenna receive mode. The device further includes a control circuit configured to detect selection of the single antenna receive mode as an active one of the multiple communication modes and to automatically alter a configuration of the plurality of antennas and transceiver by configuring the first antenna as a transmit only antenna and the second antenna as a receive only antenna responsive to detection of the selection of the single antenna receive mode. Related methods of operation are also discussed.
