Speedway Reader IPJ-R1000 for Gen 2 UHF RFID

Figure 4-2 Speedway Reader Settings Page

Mode

The reader mode is established via the Mode pull-down menu. Mode profile is a factory preset that configures the reader

according to the mode’s respective default settings.

Antenna

The Speedway reader supports four (4) independent, bidirectional, full duplex TX/RX ports, which must be cabled to their

respective, Impinj-approved antennas prior to power-up. Each antenna port is labeled (ANT1−ANT4) on the Speedway unit,

and these designations correspond to the Antenna selection buttons that appear on the lower third of the screen. Only those

antennas activated by clicking the appropriate button(s) will be operational.

Session

The reader may be assigned to one of three Sessions (1−3), selectable via this pull-down menu. A function of dense-reader

mode, the use of sessions allows as many as three different readers to access the same population of tags through a time-

interleaved process. In this mode, a shelf-mounted reader in the midst of a counting operation (assigned to, say, session 1), for

example, may be interrupted by another reader entering the field—possibly a handheld reader—to perform its own inventory

operation (in session 2, perhaps). A dock door or forklift reader, assigned to session 3, might also initiate an inventory round.

Because Gen 2 tags maintain a separate "inventoried" flag to keep track of each of these various random and independent

sessions, they're able to seamlessly resume their participation.

Transmit Power

The reader power setting is selected from the Tx Power pull-down menu. The output power ranges from 15 dBm to a

maximum of 30 dBm (in .25 dB increments), measured at the Speedway reader's antenna ports.

Channel

The FCC stipulates frequency hopping across the North American spectrum allocated to UHF RFID (902−928 MHz, with

hopping occurring between 902.75−927.25 MHz in 500 KHz steps). As such, the Speedway reader does not allow the setting

of a static frequency. For North American operation, Channel is factory-set and fixed to frequency hop.
