Abstract
Techniques for using at least one of omni-directional and directional antennas for communication are described. A station may be equipped antenna elements selectable for use as an omni-directional antenna or one or more directional antennas. The station may select the omni-directional antenna or a directional antenna for use for communication based on various factors such as, e.g., whether the location or direction of a target station for communication is known, whether control frames or data frames are being exchanged, etc.
Claims16
An apparatus for wireless communication, comprising:
- at least one integrated circuit configured to send a Request to Send (RTS) frame to a station via an omni-directional antenna, to receive a Clear to Send (CTS) frame from the station, to select a directional antenna based on the CTS frame, and to send at least one data frame to the station via the selected directional antenna.
A method for wireless communication, comprising:
- sending a Request to Send (RTS) frame to a station via an omni-directional antenna;
- receiving a Clear to Send (CTS) frame from the station;
- selecting a directional antenna based on the CTS frame;
- and
- sending at least one data frame to the station via the selected directional antenna.
An apparatus for wireless communication, comprising:
- means for sending a Request to Send (RTS) frame to a station via an omni-directional antenna;
- means for receiving a Clear to Send (CTS) frame from the station;
- means for selecting a directional antenna based on the CTS frame;
- and
- means for sending at least one data frame to the station via the selected directional antenna.
An apparatus for wireless communication, comprising:
- at least one integrated circuit configured to receive a Request to Send (RTS) frame from a station via an omni-directional antenna, to select a directional antenna based on the RTS frame, and to receive at least one data frame from the station via the selected directional antenna.
A method for wireless communication, comprising:
- receiving a Request to Send (RTS) frame from a station via an omni-directional antenna;
- selecting a directional antenna based on the RTS frame;
- and
- receiving at least one data frame from the station via the selected directional antenna.
An apparatus for wireless communication, comprising:
- means for receiving a Request to Send (RTS) frame from a station via an omni-directional antenna;
- means for selecting a directional antenna based on the RTS frame;
- and
- means for receiving at least one data frame from the station via the selected directional antenna.
