Frequency and Time Multiplexing

In any toll site involving multiple simultaneous transmitting antennas either frequency division or

time division between adjacent trasmitting antennas is required. The required spacing and re-use

guidelines are discussed in Installing an Antenna and Appendix B FCC Approved Port Frequencies and

Selection which provides details on the FCC permitted Frequencies and ERP.

The TDM time sequence is controlled by the TDM Panel as part of the frame sequence, see Frame

Sequence building, page 59

Frequency Selection

In Tag Protocol page, click protocol icon to show details. In the Frequency panel, choose the desired

operation frequency for each port.

Note1: There should be at least a 2.5 MHz separation between adjacent Ports both on Ports in

a reader and between adjacent Ports of adjacent readers.

Note2: The FCC allowed frequencies are protocol specific. See Appendix B

Note3: Normally the frequency selected will be the same for all FDM protocols on a Port

Note4: The TDM frequencies cannot be changed

Result: The following screen is shown as an example (TDM protocol in 4 Port configuration).
