Abstract
In some aspects, a reader device may communicate with one or more first radio frequency identification (RFID) tags, during at least part of a first time period, using a first antenna of the reader device. The reader device may communicate with one or more second RFID tags, during at least part of a second time period, using a second antenna of the reader device. The reader device may select the second antenna over the first antenna based upon at least one switching metric associated with the first time period. Numerous other aspects are described.
Claims20
An apparatus for wireless communication at a reader device, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the reader device to:
- communicate with one or more first radio frequency identification (RFID) tags, during at least part of a first time period, using a first antenna of the reader device;
- and
- communicate with one or more second RFID tags, during at least part of a second time period, using a second antenna of the reader device,
- wherein the second antenna is selected over the first antenna based upon at least one switching metric associated with the first time period.
An apparatus for wireless communication at a reader device, comprising:
- one or more memories;
- and
- one or more processors, coupled to the one or more memories, configured to cause the reader device to:
- receive a first message from a radio frequency identification (RFID) tag using a first antenna of the reader device;
- and
- receive a second message from the RFID tag using a selected antenna of the first antenna or a second antenna of the reader device,
- wherein the selected antenna is selected based at least in part on a measurement associated with the first message.
A method of wireless communication performed by a reader device, comprising:
- communicating with one or more first radio frequency identification (RFID) tags, during at least part of a first time period, using a first antenna of the reader device;
- and
- communicating with one or more second RFID tags, during at least part of a second time period, using a second antenna of the reader device,
- wherein the second antenna is selected over the first antenna based upon at least one switching metric associated with the first time period.
