Preventing interference in mixed operation

You ensure problem-free operation by a strict separation in the assignment of transmission
and receive channels of the RF600 readers according to EN 302 208 V1.1.1 and
EN 302 208 V1.2.1. This means that neither the transmission channels nor the receive
channels of the readers operated according EN 302 208 V1.1.1 must overlap with the
transmission or receive channels of the readers operated according to EN 302 208 V1.2.1.
Procedure
1. In the channel plan, only mark the transmission channels as assigned channels of a reader
for all readers that are not to operated in dense mode (EPC Global Class 1 Gen 1,
EPC Global Class 1 Gen 2 (no dense mode)) or ISO 18000-6B).
2. For all readers that are to operate in dense mode (EPC Global Class 1 Gen 1,
EPC Global Class 1 Gen 2 (dense mode)), mark the transmission channels and the
channels right next to them (receive channels) as assigned channels of a reader.
3. For this purpose, first mark all transmission channels and any adjacent receive channels
in dense mode operation of the R660R readers for V1.3 or later versions in the channel
plan. In mixed operation, the RF660R reader operated according to EN 302 208 V1.1.1
can use more channels than an RF660R reader operated according to EN 302 208 V1.2.1.
4. Then mark all transmission channels and any adjacent receive channels in dense mode
operation of the R660R readers for V1.2 or earlier versions in the channel plan.
