Moxa has released the WDR-3124A, its first wireless router that combines both WLAN and WWAN connectivity to ensure that wireless devices are connected anywhere, anytime. The WDR-3124A’s innovative auto-switch failover function enables automatic switchovers between 802.11n and HSPA standards, ensuring wireless availability for mission-critical systems.
Many industrial applications rely on moving equipment during operation, such as tramways in transportation or tank trucks in oil and gas applications. When operators need to access critical data onboard, there are two ways to build a wireless network. One way is to deploy a wireless client onboard to communicate with APs at each station. Another way is to deploy a cellular device onboard and communicate with the control centre directly. However, neither solution alone is ideal. According to Moxa product manager Sean Lin, “Long-distance transmission between remote stations is subject to WiFi access failures and cellular communication can be expensive. The WDR-3124A combines both 802.11n and HSPA connectivity for seamless auto-switch failovers so operators can set WiFi as the primary connection and automatically switch over to cellular if the WiFi link goes down. This not only ensures seamless connections, but also reduces costs for cellular airtime since the cellular connection is only used when the WiFi network is inaccessible.”
To ensure reliable wireless LAN and WAN connections, the WDR-3124A also supports Moxa’s Turbo Roaming technology for seamless WiFi roaming within milliseconds. For cellular transmission, dual SIM card slots with GuaranLink technology ensure reliable cellular transmissions, making the WDR-3124A an ideal wireless router for wireless applications that require both LAN and WAN connectivity.
