Test Case 3.3: TD.8.5.1.3 Synchronization with 10 Long Beacons
This test verifies that the DUT synchronizes correctly in the presence of multiple
beacons in slots 2–11 with nominal intervals of 65538 microseconds and with 300 byte
beacon payloads. Each beacon is sent a random number of microseconds early (0 to
4us) to verify the DUT tracks to the slower tester BPST.
Test procedure:
1.
Start analyzer capture with filter set to only capture beacon frames.
2. Start test system transmitting beacons in slots 2–10 with nominal intervals of
65538 microseconds (as reported by the analyzer). Each beacon is sent a random
number of microseconds from 0 to 4 earlier than the scheduled location based on
the nominal interval. The BP Length is set to 21. Each test system beacon
includes enough minimum length test mode IEs (with the subtype set to zero) to
increase the beacon payload length to at least 290 bytes, but not more than 300
bytes.
3. Standard test start-up sequence.
4. After 5 minutes, test system stops beaconing.
5. After at least 2 seconds, stop the analyzer capture.
Notes:
• Background observation checks verify DUT & INTD follow correct signaling and
slot contraction behavior
Test Case 3.4: Synchronization with 10 Beacons with the NULL EUI-48 (FF-FF-FF-FF-FF-FF)
and the same DevAddr
This test verifies that a DUT will join an existing beacon group with 10 beacon slot
occupied and slightly skewed BPST. Each beacon is transmitted earlier than the
scheduled location (from 0 to 4us). The BP Length is set to 21. The EUI 48 in all the
test system beacons is set to NULL and the DevAddr is set to 2.
Test procedure:
1.
Start analyzer capture with filter set to only capture beacon frames.
