Thanks for joining the eero community, houghtona  I'd be happy to answer your question.

eero currently uses specific industry standards, including 802.11r, to help form and maintain great connections to your devices. These standards, along with our proprietary mesh and additional roaming technology, help ensure that your data is taking the fastest route from your device to the internet. 

I hope this is helpful! Let me know if you need any further clarification.
