methods involving higher arti?¬?cial intelligence in the central control unit, depending on
the noise received from the surrounding environment, but these await full development.
7.7 Variation of Synchronization
In the previous sections, suggestions on the implementation of a real life RFID reader
synchronization system are presented, together with some deployment options, such as the
connectivity of all the readers. In addition, ?¬?ne-tuning methods are presented. In this section,
some of the interesting variations of RFID reader synchronization schemes are presented.
These variations may not be readily incorporated into the suggested methods mentioned in
previous sections, but are presented here for future reference and for completeness.
7.7.1 Separation of Transmitting and Receiving Channels
For the RFID full-power operation (2 W ERP) as governed by ETSI 302 208, only
10 channels are available as shown in Figure 7.7. However, as discussed in Section 7.2,
there are actually 15 channels available for RFID in total. Five of the ?¬?fteen channels,
though used as guard bands, can be used for RFID operation with reduced maximum
allowable radiated power.
