Introduction

The TAP-323 Series Wi-Fi 4 (802.11n) railway train-to-ground wayside IP68-rated dual-radio wireless APs are built for CBTC, CCTV, and BBRS communications, supporting seamless controller-based Turbo Roaming with handover times under 50 ms. They are highly compact and rugged wireless units combining two access points, a managed fiber switch, and a wide-range AC/DC power supply into a single box. The TAP-323 Series can supply power to up to four PoE devices while providing reliable LAN communications powered by Moxa’s Turbo Chain technology.

WLAN Standards

2.4 GHz: 802.11b/g/n with 64 QAM support, 20/40 MHz
5 GHz: 802.11a/n with 64 QAM support, 20/40 MHz
Frequency Band for US (20 MHz operating channels)

TAP-323-US models only:
2.412 to 2.462 GHz (11 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 (8 channels) Excludes 5.600 to 5.640 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.
