It's easy for the 2.4 GHz spectrum to get crowded and suffer issues. Zigbee runs on the 2.4GHz frequency with rapid transfer rates, which is comparable to a frequency for Wi-Fi. All Digi XBee modules support a common command language and communications interface, so switching between protocols is easy, and can often be . When you turn on your Sengled bulb using the app, the signal is sent to your router, then the Sengled Smart Hub (or compatible hub) translates that command into a Zigbee signal and sends it out to the bulb. II. ZigBee was established in the late 1990s as an alternative to Wi-Fi and Bluetooth for some applications. The expectations for 802.11ax are high due to its network access enhancements, which will naturally provide secondary benefits of IoT enablement. Having said all of this, Zigbee is actually fairly similar to WiFi in many respects - it operates on the 2.4 GHz radio frequency band, it has a similar default range to many real-world WiFi setups, and it requires some sort of controller device (a hub/router type device) somewhere within the network. This is because the latter runs on a lesser-used radio frequency, 908.42 MHz, whereas the former runs on 2.4 GHz making it a Wi-Fi competitor. When deploying both Wi-Fi and ZigBee in the same environments, careful planning must be performed to make sure that they don't interfere with each other.
