That is not true. Zigbee and Thread both uses 2.4GHz on the ZBT-2 (so think might be confusing Zigbee or Thread with Z-Wave and the ZWA-2 adapter which does use Sub-GHz frequencies).

@matthewcbyington while in theory there could be a little interference between Zigbee and Thread adapters those both uses low-power radios that send very short messages at low bandwidth, so in a real-world scenarios you do not need to worry about Zigbee and Thread interfering with each other.

Now what you do need to worry about is keeping Wi-Fi radios, USB 3.0 devices/cables (like external harddrives) and any electical appliances or power-supplies too close to Zigbee/Thread radios.

Highly recommend reading and following these best pracites for Zigbee (also applies to Thread too):

Who is this guide for? I have tried to make this guide to be a comprehensive collection of the most basic yet essential tips with a set of actions and best practice steps that should be applicable to all types of Zigbee setups, regardless of what type of Zigbee adapter/gateway/hub/bridge/devices that you are using. This guide is meant for both those who are new to Zigbee as well as those who been using Zigbee devices for years but might not been aware of the underlying prerequisites to optimiz…
