8 Performance and Test Data

For this revision, a test with a 100-node mesh network and a 5-hop network topology was carried out. The border router pings each device periodically one by one. The ping packet size is 50 bytes; ping interval is 5 seconds with a ping response timeout of 30 s. The test is run for 24 hours.

Test Parameter Result
End-to-end delay Hop 1: 373 ms
Hop 2: 471 ms
Hop 3: 574 ms
Hop 4: 760 ms
Hop 5: 899 ms
Overall average: 583 ms
Average packet error rate (PER) 0.001%
Average network join delay 48.3 minutes

Looking at the average join delay, the designer must consider that this is tested with a 100-node network with the 5-hop architecture as shown in Figure 4. Every hop incorporates a different number of router nodes. Table 9 lists a differentiation of join delay per hop. The average join delay per hop is defined by the average time it takes from powering up the devices until 100% of the nodes in one hop have joined the network.

An out-of-the-box network with 2-3 nodes joins in 3 to 5 minutes after powering up. The exact join time is dependent on multiple timing factors and the desired data rate. Configure these settings in SysConfig.

Table 10 TI Wi-SUN® FAN 1.0 Performance Data
Performance Data Result
Maximum network hops Wi-SUN® FAN 1.0 standard supports up to 24 hops
Maximum network size Network size is limited by border router's RAM, in addition to application use-case details. TI recommends using up to approximately 100 nodes per border router for devices with 144KB RAM. Multiple border routers can be used to scale the network. TI devices with larger memory can support larger networks.
PHY certification results Wi-SUN® FAN 1.0 PHY for:
  • US and BZ regions
  • EU1, EU2, IN, and SG regions
FAN certification results Wi-SUN® FAN 1.0 certified router stack

The OAD tests were conducted with an image size of 352256 Bytes using different block sizes. The results vary depending on the number of hops that the data has to travel to the destination. OAD was tested for a maximum hop count of 2. Consider these values to be taken in a mostly noise-free environment. Heavy traffic leads to repeating packets, which increases the total download duration.
