IEEE 802.11 a/n Wi-Fi AP/Client

  • Compliant with IEEE 802.11 a/n
  • IP55 waterproof certification
  • MIMO 2 x 2 11n
  • External RP-SMA connectors for 2T2R antennae
  • High output power
  • Passive 24 V PoE
  • WPA/WPA2-Enterprise encryption for a highly secure wireless network
  • WEP/WPA/WPA2/ IEEE 802.1 x authentication support

The EKI-6331AN is a feature rich wireless AP/Client which provides a reliable 5GHz wireless connectivity for industrial environments. The PoE injector enhances flexibility in deployment of this AP/Client even where the DC power supply is hard to fulfill. As an 802.11n compliant device, EKI-6331AN provides 6 times higher data rates than legacy 802.11a devices. With MIMO 2 x 2 technology, EKI-6331AN provides both robust wireless connectivity as well as high throughput rate in wireless transmission. With the support of WMM and IGMP snooping protocols, EKI-6331AN effectively improves the reliability of wireless connectivity, especially in applications that need high reliability and high throughput data transmission. To secure wireless connections, EKI-6331AN implements the latest encryption technologies including WPA2/WPA/802.1x for powerful security authentication.
