Moxa AWK-3131 and AWK-4131 series 3-in-1 wireless AP/bridge/clients

Moxa has released the AWK-3131 and AWK-4131 series, two high-bandwidth 3-in-1 industrial wireless AP/bridge/clients that provide secure wireless coverage both indoors and out. Both series are fully compliant with the IEEE 802.11n standard for a maximum bandwidth of 300 Mbps and are backward compatible with existing 802.11 a/b/g deployments.

The company’s 802.11n products use a combined technique of MIMO (multiple input, multiple output), channel bonding and frame aggregation. MIMO is the key technology for enhanced data rates in 802.11n networks. It enables a link where both the transmitting end and the receiving end are equipped with multiple antennas, creating multiple paths for the radio signals. This technology eliminates the effects of multipath fading on the receiving end for improved wireless range and reliability. The 802.11n standard couples MIMO technology with the channel bonding operation in the physical layer, which bonds two 20 MHz channels together to increase the bandwidth that is available for data transfer to 40 MHz. Finally, frame aggregation technology greatly reduces the average delay by packing multiple frames in a single transmission. Together, these three elements of 802.11n network technology ensure high reliability while satisfying higher throughput demands up to 300 Mbps.

Both the AWK-3131 and AWK-4131 series feature rugged housings that are necessary for harsh industrial environments. Both series also feature industrial-grade QoS and VLAN for efficient data traffic management and integrated DI/DO for on-site monitoring and warnings. The AWK-4131 is an outdoor model with an IP68-rated metal housing that is designed to withstand harsh environments and extreme temperatures from -40 to 75°C.
