Installation
Because Speedway/R is capable of up to +32.5 dBm conducted power on the housing RF
connector, professional installation is required.
Power
Speedway/R may only be operated with Impinj-approved antennas and can radiate no
more than 36 dBm EIRP (Equivalent Isotropically Radiated Power) per FCC Part 15.247
regulations. The Speedway/R output power may be increased to provide the maximum
allowable EIRP subject to a maximum conducted power allowance as well. The maximum
conducted power at the antenna connector can be no more than 30 dBm. The maximum
allowable output power of the reader can be set to satisfy both the conductor and radiated
maximum criteria. The expression for the maximum reader power setting is:
where the composite antenna gain comprises the maximum linear antenna gain in dBi
minus any cable loss between the reader and antenna in dB. Approved antenna vendors,
model numbers, and associated gain are listed in the next section.
