System and method for transmission parameter control for an antenna apparatus with selectable elements
View Patent ↗A system and method for improved data transmission on a wireless link to a remote receiving node includes a communication device for converting packets to RF at a physical data rate, an antenna apparatus having a plurality of antenna configurations for transmitting the RF, and a processor for selecting the antenna configuration and the physical data rate based on whether the remote receiving node indicated reception of the data transmission. The processor may determine a table of success ratios for each antenna configuration and may rank each antenna configuration by the success ratio. The processor may transmit with an unused antenna configuration to probe the unused antenna configuration and update the table of success ratios. Similarly, the processor may maintain a table of effective user data rates, rank each physical data rate by the effective user data rate and probe unused physical data rates to update the table.
1. A system for wireless communication, comprising:
a plurality of antenna elements including one or more selectable horizontally polarized antennas and one or more selectable vertically polarized antennas that transmit or receive a radio frequency (RF) signal with a remote node through a wireless link;
an antenna element selecting device that selects a first combination of one or more of the plurality of antenna elements to transmit or receive an RF signal; and
interference detection circuitry that detects interference in the wireless link, the antenna element selecting device further selecting a second combination of one or more of the plurality of antenna elements to transmit or receive an RF signal when the interference detection circuitry detects wireless link interference.
2. The system of claim 1 , wherein the interference detecting circuitry includes a processor that executes code that detects feedback in a signal received from the remote node and to select an antenna configuration in response to the feedback.
3. The system of claim 1 , wherein the interference detecting circuitry selects a physical data rate at which to transmit an RF signal.
4. The system of claim 1 , wherein the physical data rate is approximately 2.4 gigahertz.
5. The system of claim 1 , wherein the physical data rate is approximately 5.0 gigahertz.
