While a 2.4GHz Wi-Fi band can cover more area, being perfect for larger homes, the downside is that you’ll likely experience slower speeds and be prone to interference from other electronic devices.

2.4GHz also doesn’t need a mesh network to enable its reach, which most other wireless protocols in the smart home do. “2.4GHz Wi-Fi is table stakes.

The power is so low, and the protocol so different that it really doesn't matter. Bluetooth and WiFi are both ~2.4Ghz and those radio antennas are usually on top of each other in a laptop.
