ExcitationId frames. By using two loops to generate the field the resulting excitation field provides
a more reliable excitation for tags (independent of their orientation) with a compact spatial
presence compared with the previous exciter models.
3.3. UHF transmitter
Exciter EX23G includes an UHF transmitter capable of transmitting its digital ID using
messages on 433.92 MHz channel. These UHF messages can be used to communicate wirelessly
the EX23G operational status and in the same time to check the reception performance of the
Readers located in the neighborhood.
The interval of time separating two transmissions and the number of messages in the packet are
programmable by parameters, Table 2 listing the available user-programmable parameters.
