Deploying long distance communication is usually expensive for industrial applications that require a fast and reliable connection. Moxa’s AWK-3191 wireless AP/bridge/client not only eliminates the wiring expense, it also gives users field tested 900 MHz wireless communication at a 6 Mbps data rate over a distance of 30 km, providing an excellent alternative to expensive microwave radios.

Unlike traditional point-to-point 900 MHz devices, the AWK-3191 supports both master/slave and AP/client operation modes to enable both point-to-point and point-to-multi-point communication for the kind of line-of-sight applications required by a wide range of applications, including open-pit mining, offshore drilling, pipeline monitoring, and oil and gas.

The AWK-3191 follows the 802.11 standard to provide reliable and secure wireless communication, and uses frequency-shifting technology to allow advanced users to adjust the central frequency and communication bandwidth to avoid signal interference. Together with Moxa’s industrial design, which includes a wide operating temperature of -40 to 75°C and power and antenna isolation, the AWK-3191 is truly the best long range wireless solution for industrial applications.

Deploying Reliable, Long Distance WLAN Solutions

• 900 MHz AP/bridge/client

• Proven 30 km @ 6 Mbps P2P connection

• 902 to 928 MHz adjustable central frequency

• Antenna and power isolation

• 802.11i WEP/WPA/WPA2 encryption

• -40 to 75°C operating temperature

Field Test: Proven performance and reliability over a distance of 30 km

Open-Pit Mining ApplicationsOpen-pit mining typically covers a large area, and requires an extremely reliable wireless connection to ensure operational safety and efficiency for distributed communication and data exchanges.. The AWK-3191 leverages the lower 900 MHz frequency bands to ensure better penetration and longer range communication, and by following the 802.11 protocol, this solution can handle more data than traditional long distance microwave solutions.

Wireless communication is essential for offshore applications, which provide a bigger challenge for network communications due to the likelihood of encountering severe weather conditions. In this case, signal strength and sufficient bandwidth are both critical. The AWK-3191 provides reliable wireless communication by enhancing its signal integrity with frequency-shifting technology and a rugged design, helping ensure operational safety and productivity in offshore conditions.
