Robust wireless backbone solution AP-5312F

AP-5312F – 802.11n Access Point

Neratec AP-5312F is a robust high-performance wireless backbone solution for industry and public transport.

  • Based on 802.11 WLAN technology, adapted for special in-vehicle and onboard requirements
  • Separate RF monitoring interface
  • Supports reliable operation in outdoor Radar (DFS) bands
  • 2.4 GHz and 5 GHz operations, up to 450Mbps Data rate
  • Better link span-optimized transmitter and receiver performance 
  • IP66 housing and extended operating temperature range: -40°C to 70°C
  • 1 x 1000Base-FX optical Ethernet
  • 1 x 10/100/1000Base-T Ethernet with M12 connector
  • 100...240VAC power feed


The Neratec DAP-5312F is the infrastructure-side 802.11n solution for a wide variety of wireless applications including, for example, onboard-to-trackside or vehicle-to-infrastructure communications, passenger information systems, remote control and maintenance, wireless voice communications and video surveillance.

Thanks to its optical Ethernet interface the AP-5312F can also be used as a reliable wireless backbone solution in very large installations. Once the initial configuration is done, the device can be remotely managed using a standard Web browser or SNMP management tools.

IEEE 802.11 compatible – with more performance

Neratec AP-5312F is compatible with the IEEE 802.11 standards, but designed for demanding and harsh environmental conditions where complex radio propagation constellations, physical shocks and vibrations are present. 

Thanks to its second RF interface used for monitoring purposes the AP-5312F enables applications to use 5GHz outdoor radar frequencies reliably. 

AP-5312F uses the same high performance RF front end as DT-5302R meaning that it is also optimized for better link span, faster roaming, higher payload data rates and improved resistance against typical electrical interferences in industrial environments. These features provide more reliable data communications, best-in-class service availability, long lifespans and lower lifecycle costs.

Installations and Applications

Neratec AP-5312F provides optical Ethernet and direct 240VAC power feed which makes it very suitable for any large or small infrastructure installation. Typically the Neratec AP-5312F is used as part of a system solution developed and installed by wireless system integrators and service providers. Typical installations consist of 50 to 500 Neratec AP-5312F access points as backbone and support a large number of mobile or stationary Neratec or third-party devices as clients. As with all Neratec WLAN products, customers benefit from long-term availability, high reliability and good system integration support based on Neratec in-house development.

Applications for Neratec AP-5312F include:

  • Outdoor / Railway Infrastuctures using 5GHz DFS frequencies
  • Onboard-to-infrastructure communications: video, data exchange, remote control
  • Mobile passenger/driver information systems
  • Security applications at terminals and depots
  • Wireless remote control systems
  • Large area coverage wireless communications for moving objects in industrial environments
