802.11a/b/g/n/ac access point, UN band, IP68, -40 to 75°C operating temperature

WLAN Interface
  • WLAN Standards

    • 2.4 GHz: 802.11b/g/n with 256 QAM support
      5 GHz: 802.11a/n/ac Wave 2 with 256 QAM support
  • Frequency Band for UN (20 MHz operating channels)

    • 2.412 to 2.484 GHz (14 channels)
      5.180 to 5.240 GHz (4 channels)
      5.260 to 5.320 GHz (4 channels) DFS (Dynamic Frequency Selection) channel support: In AP mode, when a radar signal is detected, the device will automatically switch to another channel. However, according to regulations, after switching channels, a 60-second availability check period is required before starting the service.
      5.500 to 5.700 GHz (11 channels) DFS (Dynamic Frequency Selection) channel support: In AP mode, when a radar signal is detected, the device will automatically switch to another channel. However, according to regulations, after switching channels, a 60-second availability check period is required before starting the service.
      5.745 to 5.825 GHz (5 channels)
      Available channels change depending on the selected country or region code.
