Introduction

The AWK-4252A Series are a range of 3-in-1 industrial wireless AP/bridge/clients engineered for reliable wireless connectivity in harsh outdoor environments such as mining, oil and gas, and transportation. Their robust enclosure provides superior protection against the elements, while antenna isolation and power isolation protect against ESD and power surges. The built-in 2.4/5 GHz band-pass filter minimizes out-of-band interference.

Featuring AeroMesh technology, the AWK-4252A Series simplifies network deployment where cabling is impractical or costly. Self-forming and self-healing wireless paths speed up deployment and configuration in highly dynamic applications while minimizing downtime.

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)

  • 802.11r Fast Roaming enables faster, more reliable Wi-Fi client roaming and improved third-party interoperability

  • DFS channel support for a wider range of 5 GHz channels to avoid interference from existing wireless infrastructure

  • AP-based client disconnection mechanism to help wireless clients without roaming intelligence obtain optimal AP services

  • Universal (UN) models with configurable country for more flexible global deployment

  • Dedicated MXview Wireless network management software with dynamic topology view, interactive roaming history playback, and detailed device information and performance indicator charts

  • Latest WPA3 encryption for enhanced wireless network security

Industrial Compliance and Certifications
