What is the minimum transmit power I can configure with the IImpinj R700 & R720 RAIN UHF RFID 4-Port Reader series?What options are available to power the IImpinj R700 & R720 RAIN UHF RFID 4-Port Reader series?The Impinj R700 series readers are powered exclusively via power over ethernet (PoE or PoE+). Many commercial switches offer this capability. For use cases that require AC connectivity, Impinj sells a midspan injector (P/N IPJ-A2010) that adds PoE+ capability to an existing network connection. There are many commercial off-the-shelf options available for other PoE injecting solutions.
What are the power requirement differences between the Impinj R700 and Impinj R720?The Impinj R720 requires approximately 2 watts more power than the Impinj R700 & R720 RAIN UHF RFID 4-Port Reader series. Due to this difference, it is recommended to use PoE+ to power the R720. PoE power is only recommended for the R720 if the device is running a transmit power of 20 dBm or less and is not using any peripherals.
How can I set the maximum receive sensitivity of -93 dBm with the Impinj R700 series readers?Maximum receive sensitivity varies depending on the reader mode you select. In the Impinj ItemTest software, check the “Enable Max Sensitivity” option to use the maximum receive sensitivity for the reader mode you are using.
When using the Impinj IoT device interface, omitting the “receiveSensitivityDbm” field from a preset configuration JSON will cause the reader to report tags at the greatest sensitivity for any given mode.
For more information on different RF Modes on the Impinj R700 & R720 RAIN UHF RFID 4-Port Reader series, please refer to Impinj R700 Reader Modes (RF Modes) article.
For more information describing how to optimize your deployment for receive sensitivity, please refer to Why Receive Sensitivity Matters article.
Why did the published R700 receive sensitivity values change from -92 dBm to -93 dBm?Along with the launch of the R720, Impinj changed their standard methodology for measuring receive sensitivity for all fixed readers, including both the R700 series and Speedway series products. The new methodology is better aligned with RAIN Alliance recommendations and the ISO 18046-2:2020 industry standard. This change appears to have improved the published values, however, Impinj’s fixed readers have not had any changes made to them that functionally improved their receive sensitivity.
For more information about this new methodology, including step-by-step directions, please refer to the How to Perform Reader Sensitivity Testing application note.
How can I know which antenna port an Impinj R700 & R720 RAIN UHF RFID 4-Port Reader series is using to read tags?ItemTest software’s Antenna column automatically displays which antenna port that the Impinj R700 series reader is using to read tags.
If you are using IoT Device Interface on 8.2.0 or newer firmware, under the Tag Streaming tab, there is an Antenna column that displays the antenna port number that last read a particular EPC.

For PoE, are there any requirement differences between Impinj Speedway series and Impinj R700?Yes, power requirements vary depending on the use of power drawn from the USB ports, the current draw from the GPIO port, and the length of the Ethernet cable from the power source to the reader. These differences for R700 are outlined in the table below:
Power Source TX Max Cable Max GPIO + USB Max
802.3at PoE+ 33 dBm 100 Meters 5V/500 mA
802.3af PoE 27 dBm 100 Meters 5V/500 mA
802.3af PoE 30 dBm 60 Meters None
These differences for R720 are outlined in the table below:
Power Source TX Max Cable Max GPIO + USB Max
802.3at PoE+ 33 dBm 100 Meters 5V/500 mA
802.3af PoE 20 dBm 60 Meters None
In general, the more power that is being used, the more likely that PoE+ will be needed to supply enough power to keep the reader operating without "browning out". For more information, please refer to the R700 Installation and Operations Guide found here.
