The Dual-PAN feature of the KW2x allows the single 802.15.4 radio to participate in two different networks simultaneously, switching back and forth between the 2 networks under software or hardware control. The typical use case model would be one higher duty cycle network and one network with a low duty cycle. One example is a remote control and home automation using the following Freescale software stacks; RF4CE and ZigBee HA. Figure 1 shows the Daul PAN use case model:
Figure 1: Daul PAN use case model
The figure shows a remote node participating in two networks where it is communicating within its RF4CE network and a home automation network. This would be a type of low duty cycle application.
