This virtually extends the communications range with multiple Reader/Writers, and communicated with
RF Tags detected by any of the Reader/Writers.
Use RF Tag communications in the following applications.
• Once multiple RF Tags passing through in logistics/transport, etc., have been read, RF Tag communi-
cations are possible at high reading accuracy by arranging multiple Reader/Writers and creating a
wide communications range.
• If a point where the RF Tags are unreadable (null point) is generated due to the cancellation
(multi-path) of the radio waves due to reflected wave in the ambient environment, RF Tag communi-
cations will be possible at high reading accuracy if multiple Reader/Writers are arranged, supple-
menting the null point.
