  • Patent number: 10263753
    Abstract: In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.

  • Publication number: 20180212669
    Abstract: A wireless communication device includes a number of radio-frequency (RF) antennas and one or more radio circuits. Each radio circuit includes a receive (RX) chain to process RX signals and a transmit (TX) chain to process TX signals. An RF switch network couples at least one RF antenna to at least one radio circuit. A baseband processor controls a configuration of the RF switch network. The baseband processor determines a plurality of parameters and controls the RF switch network based on at least one of the parameters. The parameters are determined during a training interval including at least an inter-frame space (IFS). The configuration of the RF switch network is based on the determined parameters and is employed for selection of an antenna to improve a link performance when used for communication of a next packet following the IFS.
