Lab 3: 802.15.4 Channel Assignment Our motes use the physical layer of 802.15.4, which is uses part of the free spectrum. This free spectrum is shared with other technologies as well, 802.11 (WiFi) for example: In order to avoid interferences, each group will use a different channel: Group Channel 1 23 2 22 3 21 4 20 5 19 6 18 7 17 8 16 9 15 10 14 11 13 12 12 13 11 The channel needs to be changed in the makefile. If you are going to change your channel for testing the difference between channels, please let the lab assistant know about it.
