Introduction
The AWK-3251A-RCC Series is a range of IP30-rated Wi-Fi 5 (802.11ac) AP/clients designed for railway onboard use, providing a reliable solution for dedicated applications such as inter-carriage backbone networks and onboard passenger infotainment systems. The Auto Carriage Connection (ACC) feature simplifies deployment and enhances the reliability of wireless carriage backbone networks. Optimized for passenger Wi-Fi services, the AWK-3251A-RCC Series supports concurrent 2.4/5 GHz dual-band connectivity, up to 120 client connections, and data rates of up to 1.267 Gbps. In addition, the AWK-3251A-RCC Series can be powered via PoE for easier installation and flexible deployment.

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 2.472 GHz (13 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.
