A. Regions of Operation
The BLUEBOX reader has been designed to work in various regions with
differing frequency requirements. This document covers operation in North
America and Europe.
In each region, the reader is not locked to only operate in the
specific frequencies listed in the respective frequency plan tables
shown in next paragraphs. The user is responsible to correctly use
the
BLUEBOX in the relative region.
A.1. Operation in North America
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 specification states that no listen-
before-talk is performed, the maximum continuous transmit time on a channel
is 0.4 seconds.
RF Channel Frequency [MHz]
1 902.75
2 903.25
3 903.75

49 926.75
50 927.25
A.2. Operation in Europe
For European operation, the BLUEBOX reader supports the frequency plan listed
in the table below and is compliant with the ratified ETSI EN 302-208
specification V.1.4.1. 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.
In some applications (i.e. conveyor systems) it may be necessary for
interrogators to transmit while tags are not present. To accommodate such
requirements, the device shall include within interrogators a means to minimize
