From 2G to 3G technology, to the current 4G network development, cellular networks are becoming faster and coverage is expanding rapidly. Moxa’s advanced OnCell and WDR series are engineered with HSPA and LTE to significantly improve communication speeds and are designed specifically for remote monitoring in industrial applications. A Moxa OnCell device is available for every key role on a cellular network, including as a modem, IP gateway, and router. OnCell and WDR devices are assigned an IP address by your service provider (your “cellular ISP”), and outgoing TCP/IP connections are handled with Network Address Translation (NAT), allowing any number of local Ethernet devices to act as outgoing TCP/IP clients to access remote servers. However, the OnCell appears as a single IP address to the “public” Internet. This means that incoming connections must be forwarded manually, with port forwarding (or sometimes known as virtual server) based on TCP port number, to the local Ethernet devices. The OnCell enables traditional serial (RS-232/422/485) devices to transmit data over the cellular network. The OnCell is a tiny computer equipped with a CPU and TCP/IP protocols that can bi-directionally translate data between the serial and IP formats. With this solution, your computer will be able to access, manage, and configure remote facilities and equipment over the cellular network from anywhere in the world. IP-based OnCell products allow you to communicate with your remote devices over a TCP/IP cellular network. As long as your host computer supports the TCP/IP protocol (Internet), your SCADA and data collection system will be able to access all devices connected to a standard TCP/IP network, regardless of whether the devices are deployed locally or at a remote site. Cellular IP routers and gateways are IP-based solutions equipped with a local processor and memory to store cellular profiles and use that information to “intelligently” Ethernet-to-Cellular Serial-to-Cellular IP-based Cellular Routers / Wireless Routers IP-based Cellular Gateways OnCell/WDR Series OnCell 5000 Series (3G only) WDR-3124A (3G/802.11n) OnCell G3000 Series (2G/3G) OnCell G3470A-LTE (4G) Application Reliable remote area network connectivity: WAN/SIM/Power Redundancy Wireless LAN to WAN extension/ auto-switchover between WLAN and WWAN networks Simple remote device connectivity: Ethernet/ serial/cellular connectivity Reliable video-over-LTE networks How to connect Automatic connection to cellular operator (3G only) Automatic connection to cellular operator Serial support N/A Virtualized COM port N/A LAN support WAN support Cellular WAN / Ethernet WAN** / Backup WAN Route Support Cellular WAN Security VPN/Firewall/Routing VPN* (advanced models only) Firewall/Serial Access Control VPN/Firewall/Routing Expertise Level Easy to Use Easy to Use *OnCell G3111/G3151/G3211/G3251/OnCell G3111-HSPA/G3151-HSPA IP gateways do not support VPN. **WDR-3124A wireless router do not support Ethernet WAN. establish cellular connections automatically. This means that you no longer need to worry about installing an IPC or limit yourself to traditional serial devices that have dial-up capability. You will not only eliminate the additional cost associated with deploying an IPC, but also save deployment space if your application is bound by tight space constraints. With the easy-to-use web console interface, you can enable industrial wireless communication without the need for complex AT command knowledge. Each device is engineered to transmit data as efficiently as possible, and is designed to Moxa’s exacting standards of reliability and rugged durability. In addition, our new WDR series features both cellular and Wi-Fi technologies, making it easier to enable seamless wireless connections from LAN to WAN networks. Refer to the following table for a quick overview of which products are most suitable for your application: GuaranLink OnCell and WDR IP-based products come with GuaranLink, which enables reliable, consistent connectivity. GuaranLink achieves this in a number of ways: (1) ISP initial check: The cellular device first sends a test packet to the base station and waits for a response before establishing a cellular connection, (2) Transmission-level check: Resets its cellular module before negotiating a connection to the base station, saving connection time and airtime cost, (3) Packet-level connection check: The cellular device sends a DNS lookup request to get the IP address of the intended receiver and pings a known remote host to ensure connection to the Internet, and (4) Connection- alive check: The cellular device re-registers with the base station to establish a new cellular connection to keep the connection alive after a period of inactivity.
