Industrial 802.11n/HSPA Wireless Routers

Enabling Wireless Network Connection on Demand

Industrial applications involving mobile communications, such as moving vehicles, industrial M2M, and geographically dispersed monitoring sites, face a common challenge. Communications links must be reliable and failsafe under dynamic and radio-hostile environments. To overcome this hurdle, the WDR-3124A industrial 802.11n/HSPA wireless router comes equipped with multiple radio interfaces to enable reliable mobile data access anytime, anywhere.

Certain industrial applications may be either very remote, very mobile, or both. The ability to securely extend high speed wireless networks into remote locations while maintaining mobility and user device choices is desirable in many industries. For oil and gas applications that need systems to communicate wirelessly with remote wellheads and tank farms, the WDR-3124A can be used to connect remote assets and send status data back to a control center via a 3G connection. 802.11n ability enables Wi-Fi access for field service personnel. What’s more, 802.11n WLAN can act as a client to transmit data from moving trains to wayside stations with 3G backup when Wi-Fi is inaccessible.

There are many benefits to deploying multiple wireless routers in industrial applications. Learn how Moxa industrial 802.11n/HSPA wireless routers keep your wireless networks connected at all times.

Flexible Extension
There are several benefits to deploying multiple wireless routers for network extension. First, wireless routers can be used as Wi-Fi access points to gather local data at field sites before using cellular networks for long-distance data transmission back to control center. Remote access applications, such as road intersections or metering stations, may be located over a thousand kilometers away from the control center and need a cost-effective solution to reduce cellular airtime costs by optimizing Wi-Fi connections.

   

Seamless Switchover

Another type of connection is a Wi-Fi client to communicate with access point and cellular connection as backup when Wi-Fi is inaccessible. This setup is usually seen in applications that require transmitting data from a moving device. To ensure seamless and flexible network extension, automatic detection and fast recovery time is required for seamless Wi-Fi and cellular connection switchover.

Auto-failover

Moxa’s WDR-3124A multiple wireless routers feature an auto-switchover feature that delivers seamless transmission between 802.11n radio and standard HSPA communications. When you set Wi-Fi as the primary communication link and the 3G connection as a redundant back-up path, the traffic will automatically failover to the cellular backup link within milliseconds if the primary link goes down. The seamless auto-switchover offers wireless networks flexible and always-on signal connections.
