MOXA AWK-3252A Series

The AWK-3252A Series 3-in-1 industrial wireless AP/bridge/client is designed to meet the growing need for faster data transmission speeds through IEEE 802.11ac technology for aggregated data rates of up to 1.267 Gbps.
The AWK-3252A is compliant with industrial standards and approvals covering operating temperature, power input voltage, surge, ESD, and vibration. The two redundant DC power inputs increase the reliability of the power supply, and the AWK-3252A can be powered via PoE to facilitate flexible deployment. The AWK-3252A can operate concurrently on both the 2.4 and 5 GHz bands and is backwards-compatible with existing 802.11a/b/g/n deployments to future-proof your wireless investments.

1. 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.
2. DFS (Dynamic Frequency Selection) channel support: In AP mode, when a radar signal is detected, the device will automatically switch to another channel. However, according to regulations, after switching channels, a 60-second availability check period is required before starting the service.
