Overview

The Neratec DT-5302 is a high performance Wi-Fi access point designed for onboard installations. It supports a wide variety of wireless applications including, for example, passenger information systems and maintenance, wireless voice communications and wireless video. 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 DT-5302 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.

DT-5302R is 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 DT-5302 is used as part of a system solution developed and installed by system integrators and service providers. Typical installations consist of 50 to 500 Neratec DT-5302 as access points installed onboard of vehicles or trains. DT-5302 can support a large number of third party mobile devices as clients. Our customers benefit from long-term availability, high reliability and good system integration support based on Neratec in-house development.

Applications for Neratec DT-5302 include:

  • Mobile passenger/driver information systems
  • Public wi-fi access onboard trains, buses and ships
  • Security applications at terminals and depots
  • Large area coverage wireless communications for moving objects in industrial environments
