802.11a High Power Industrial Hotspot (FCC)


Discontinued: No new product for sale. More Info
Recommended replacements: RLX2-IHA-A

The 802.11a High Power Industrial Hotspot (RLXIB-IHA) is a high-speed wireless Ethernet radio, with Power over Ethernet and Serial Encapsulation. The RLXIB-IHA operates at speeds up to 54 Mbps, using the IEEE 802.11a (5 GHz band) standard. In addition to transmit power up to 250 mW, the RLXIB-IHA offers many Industrial features including hazardous location certifications, IGMP Snooping, OFDM for noise immunity, simultaneous bridge / repeater / access point mode, OPC server diagnostics, extended operating temperature, high vibration/shock resistance and DIN-rail mounting.

Features and Benefits

Conforms to IEEE 802.11a

  • Open standard protects wireless network investment
  • High speed (54 Mbps), low latency communications
  • Radio-based IGMP snooping/querying to filter multicast industrial Ethernet maximizing bandwidth

Rugged and Powerful

  • Metal enclosure, industrial operating temperatures, vibration and shock resistant
  • Certification approved for use in hazardous locations and explosive atmosphere (UL1604 Class I Div 2, ATEX Zone 2 Category 3)
  • Transmit power and radio frequencies programmable for use globally

Data and Network Security

  • Cryptographic strength security with WPA2 - 802.11i with 128 bit AES encryption and CCM integrity check
  • Limit access to approved device MAC IDs

Flexible and Reliable

  • Single radio can be configured as an access point and repeater/bridge or as a client
  • User selectable automatic or manual network configuration (can be prioritized or fixed) with self-healing network and master redundancy for reliable large networks (e.g., SCADA)
  • Power over Ethernet (PoE) enables radio placement near antenna to reduce antenna cable costs and improve wireless network performance

Serial Device Connectivity

  • Encapsulation / de-encapsulation of serial data to / from TCP or UDP packets
  • Advanced features include multicast and Domain Name Server (DNS) support

Easy to Configure and Monitor

  • Built-in web server for browser-based configuration and remote diagnostics
  • Included OPC Server for HMI-based wireless network diagnostics
