1.4.2 Dual-Radio/Triple-Radio and BandFlex
The Zyxel Device models are equipped with two or even three WiFi radios. The Zyxel Device uses the WiFi
radios to transmit WiFi signals. This means you can configure two to three different WiFi networks to
operate simultaneously.
BandFlex allows you to select the frequency bands operating on the radios by configuration. A
frequency band is a range of frequency divided into channels which carry the WiFi signals for data
transmission. If your Zyxel Device supports BandFlex, you can configure the second radio on the Zyxel
Device to use the 5 GHz or 6 GHz bands, while the first radio is always set to use the 2.4 GHz band. The 6
GHz band provides less coverage but has the highest amount of channels among the three frequency
bands. Use the 6 GHz band for the most congestion-free transmission if your client devices supports WiFi
6E (see
).
Note: Due to each country’s regulations on frequency band usage, the available radio
bands (2.4 GHz, 5 GHz, and 6 GHz) may differ by countries or markets the Zyxel Device
products are sold to.
Note: A different channel should be configured for each WLAN interface to reduce the
effects of radio interference.
You could use the 2.4 GHz band for regular Internet surfing and downloading while using the 5 GHz or 6
GHz band for time sensitive traffic like high-definition video, music, and gaming.
See
for the supported number of radios, frequency bands, and see if your Zyxel
Device supports BandFlex.
