Test Case 3.7: Lots of Large Traffic Join Test
This test verifies that a DUT will join an existing beacon group with 7 rows MAS
reserved with a hard DRP. Tester transmits multiple data frames with 4k byte transfers
during reserved MAS slots.
Test procedure:
1. Start analyzer capture.
2. Test system starts the beacon period and sends a beacon in slot 2 with a DRP IE
that reserves the lowest 7 rows in the superframe with reservation type Hard DRP.
The target of the reservation is the test system DevAddr. The BP Length is set to 12.
3. The test system begins to transmit data frames with a 4095 byte payload at 200
Mbps with SIFS separation throughout the 7 row reservation. The destination
address for the data frames is the test system DevAddr.
4. Standard test start-up sequence.
5. After 1 minute, test system stops beaconing.
6. After at least 2 seconds, stop analyzer capture.
Notes:
• Background observation checks verify DUT & INTD follow correct signaling and
slot contraction behavior
Test Case 4.1: Bad Link Test
This test verifies that a DUT will join and stay synchronized with the tester under faulty
link conditions.
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. The beacons each contain a BPOIE
that properly indicates the presence of the other test system beacons. In addition:
Each of the test system beacons have the following behavior.
a) Randomly transmit FCS errors 10% of the time.
b) Randomly do not transmit 10% of the time.
c) Randomly indicate that other test system beacons are received with an HCS error 10% of the
time.
