Appendix

The setup described in Section 2.3 was placed in an anechoic clean room with the following devices:

  • Multirole device is Sitara AM335x™ with WL18xx™ running R8.8 release and configured as a bridge between the roles.
  • Remote STAs are Sitara AM335x™ with WL18xx™ running R8.8 release limited to 1Mbps.
  • External AP is Sitara AM335x™ with WL18xx™ running R8.8 release.
  • External STA is Linksys AE1000 dongle.

The two different network topologies are as follows:

  • The blue network includes the External AP, External STA and WL18xx™ STA role.
  • The red network includes WL18xx™ AP role and 5 WL18xx™ STAs.

Throughput was measured using iPerf tool running UDP for 5 minutes.
