20100075611 | APPARATUS AND METHOD FOR IMPROVED WIRELESS COMMUNICATION RELIABILITY AND PERFORMANCE IN PROCESS CONTROL SYSTEMS - An apparatus includes a transceiver configured to transmit wireless signals to and receive wireless signals from wireless nodes associated with an industrial process. The apparatus also includes a controller configured to initiate transmission of the wireless signals and to process data contained in the received wireless signals. The transceiver includes a diversity receiver configured to process the wireless signals from the wireless nodes. The transceiver may be further configured to perform beam-shaping in order to transmit a directional beam to at least one of the wireless nodes. Also, the controller may be configured to perform spatial routing by identifying a target of a wireless transmission and to initiate transmission of the directional beam towards a known or estimated location associated with the identified target. | 03-25-2010 |

20130094422 | ANTENNA SELECTION DIVERSITY SCHEME FOR ZIGBEE OR OTHER WIRELESS DEVICES AND RELATED APPARATUS AND METHOD - A method includes identifying, at a wireless device, transmit and receive link costs respectively associated with transmitting data to and receiving data from one or more neighboring nodes of the wireless device. The method also includes selecting at least one of multiple antennas to be used to further communicate with the neighboring node(s). The at least one antenna is selected using the link costs. At least some of the link costs are identified using link status messages received from the neighboring node(s). For each neighboring node, one antenna can be selected as a unicast antenna for unicast communications with that neighboring node. Also, one antenna can be selected as a broadcast/multicast antenna for broadcast or multicast communications with multiple neighboring nodes. An identity of the at least one antenna selected to communicate with the neighboring node(s) may not be communicated from the wireless device. | 04-18-2013 |
