Features and Benefits

  • 2 dual-band radios, IEEE 802.11a/b/g/n compliant
  • Rugged IP68-rated housing and -40 to 75°C operating temperature
  • Controller-based Turbo Roaming (less than 50 ms) 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.
  • 2 fiber SFP slots and 4 PoE ports with M12 LAN connectors
  • Complies with all EN 50155 mandatory test items This product is suitable for rolling stock railway applications, as defined by the EN 50155 standard. For a more detailed statement, click here: www.moxa.com/doc/specs/EN_50155_Compliance.pdf
  • Complies with EN 50121-4

Introduction

The TAP-323 trackside wireless unit is designed for train-to-ground wireless communication. The TAP-323 is a highly compact and rugged wireless unit that integrates two access points, a managed fiber switch, and a wide-range AC/DC power supply into one box. The IP68 housing allows the unit to withstand harsh weather conditions, and the M12 connectors make the unit shock and vibration resistant. The TAP-323 supports advanced controller-based Turbo Roaming technology for train-to-ground wireless applications such as communication-based train control (CBTC) and CCTV. The unit can supply power to up to 4 PoE devices while providing reliable LAN communication with Moxa’s Turbo Chain technology.
