5 REGULATORY COMPLIANCE
5.1 FCC
This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may
not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause
undesired operation.
Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
5.1.1 Maximum Transmission Time
To comply with 15.231(a) of FCC regulations, the maximum transmission time of CT23 in Excitation or Motion modes must not
exceed 5 seconds.
To minimize collisions in an application, CT23 tags are programmed with different values for the WSD parameter, which ensures
that inter-message durations are randomized differently for individual tags. To ensure sufficient transmission redundancy in an
application a certain optimum number of transmitted messages is selected and programmed into a CT23 tag: WEP for excitation
transmissions and WMP for motion transmissions. Combination of all three parameters affects the overall transmission duration.
The following table was generated by taking into account all possible randomization patterns for a single Motion or Excitation
transmission and selecting the worst (longest) case scenario. Each cell shows the maximum possible transmission time for a given
message number and randomization pattern. In green are the fields that fall below 5 seconds. From this table we can see that for
our typical application (WEP=20, WMP=5 and WSD=10..30) we comply with the FCC regulation for maximum transmission
time.
Maximum time in seconds required to transmit a packet (burst) of WEP or WMP number of messages for a specific value of WSD.
