OpenThread是否使用频率/通道跳变？

Question

I am evaluating openthread for a project and is trying to find any information about whether it uses channel hopping. I've read the thread spec and found something about beacons on different channels when joining a network, but nothing more after that. I've also had a look through the code but must have missed the relevant sections.

What I am asking is simply does it stick to one 802.15.4 channel like ZigBee or does it use the whole available spectrum, like WirelessHART?

Answer 1

The Thread Specification uses the standard IEEE 802.15.4-2006 MAC and does not employ channel hopping - all devices on a network are configured to communicate on a single channel. The Thread Specification does include mechanisms for dynamically changing the network's channel over the air, along with other network configuration parameters.
