Introduction

The AWK-3131A Series is a range of 3-in-1 industrial wireless AP/bridge/clients designed to build reliable and interference-resistant indoor networks. They are ideal for creating robust Wi-Fi coverage in factories, warehouses, and complex RF environments. Through 5 GHz DFS channel support, the AWK-3131A Series automatically selects less congested frequencies to avoid interference and ensure stable communication.

With support for IEEE 802.11n and data rates up to 300 Mbps, the AWK-3131A Series can function as an AP, bridge, or client. Their -40 to 75°C wide operating temperature range and compact size make them a dependable choice for deployment in control cabinets and other industrial environments with limited space.

Tailored Industrial Wireless Technology

  • AP-agnostic seamless roaming with client-based Turbo Roaming 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. for sub-150 ms roaming recovery times between APs (in Client mode)

  • 2x2 MIMO technology for improved multi-stream data transmission and reception
