Latest WPA3 encryption for enhanced wireless network security
Designed specifically for rail carriage-to-carriage communication
Millisecond-level Client-based Turbo Roaming The Turbo Roaming recovery time indicated herein is an average of test results documented, in optimized conditions, across APs configured with interference-free 20-MHz RF channels, WPA2-PSK security, and default Turbo Roaming parameters. The clients are configured with 3-channel roaming at 100 Kbps traffic load. Other conditions may also impact roaming performance. For more information about Turbo Roaming parameter settings, refer to the product manual.
Built-in 2.4 GHz and 5 GHz band pass filter for more reliable wireless connections

WLAN Interface

  • WLAN Standards: 2.4 GHz: 802.11b/g/n with 256 QAM support5 GHz: 802.11a/n/ac Wave 2 with 256 QAM support
  • Frequency Band for US (20 MHz operating channels): 5.745 to 5.825 GHz (5 channels)
  • Frequency Band for US (20 MHz operating 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.
  • Frequency Band for US (20 MHz operating channels): 5.500 to 5.700 GHz (11 channels)
  • Frequency Band for US (20 MHz operating channels): DFS (Dynamic Frequency Selection) channel support: In AP mode, when a radar signal is detected, the device will automatically switch to another channel.
