Operation in European Union
Frequency Plan
For European operation, the Speedway Revolution Readers support the frequency plan listed
in Table A.2 and are compliant with the ratified ETSI EN 302 208 specification v.1.2.1. This
specification states that no listen-before-talk is performed, the maximum continuous
transmit time on a channel is four seconds, and the Reader enforces the 100 ms off time
before reusing the same channel.

Antenna Requirements
Power
European regulations allow a maximum radiated power of 33 dBm ERP (Effective Radiated
Power) for high power RFID systems. The maximum Speedway Revolution output power is
determined by the following equation:
Power) for high power RFID systems. The maximum Speedway Revolution output power is
determined by the following equation:
Maximum power setting (in dBm) = 33 – Antenna Gain (in dBd) + Cable loss (in dB)
For example, for an application with an antenna gain of 6 dBd and cable loss of 2 dB, the
Reader output power can be set no higher than 33-6+2 = 29 dBm. The maximum transmit
power of Speedway Revolution is 31.5dBm measured at the RF antenna port.
Reader output power can be set no higher than 33-6+2 = 29 dBm. The maximum transmit
power of Speedway Revolution is 31.5dBm measured at the RF antenna port.
Note
: It is important to apply the antenna gain expressed in dBd (dB with respect to a
dipole), which is equivalent to the isotropic antenna gain (in dBi) minus 2.15 dB.
Additionally, the antenna gain used to set the output power must be the maximum linear
gain of the applicable antenna. Approved antenna vendors, model numbers, and associated
gain are listed in the next section.
