Speedway Revolution Installation and Operations Guide
Appendix A: Information Specific
to Regions of Operation
Speedway/R is designed to work in various regulatory regions. This appendix includes
frequency ranges and antenna requirements specific to each supported region. Note that
this first release of Speedway/R covers operation in North America only.
Important
For each region, the reader is locked such that it can operate only in the specific frequen-
cies for that region. The region-specific frequencies are listed in this appendix.
Operation in North America
Frequency Plan
The FCC specifies 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). This is further explained in the table below:
Antenna Requirements
Positioning
Position the antenna such that personnel who will be in the area for prolonged periods of
time can remain at least 25 centimeters from the antenna's surface. This is required by the
FCC. For more details, see the following FCC bulletins:
