New industrial cellular gateways bring extensive multipath functionality to remote applications. Devices using 3G/4G cellular services round out the EtherWAN lineup of connectivity products.
Two new models of industrial cellular gateways are the EW50 and EW200. Using a standard SIM card and a cellular subscription, these devices interconnect Ethernet, serial, Digital I/O and Modbus protocols, bringing together various field assets for demanding applications. The addition of these new models allows EtherWAN to deliver a set of comprehensive solutions that are anticipated to unlock more vertical integration market opportunities.
Both devices improve application design versatility while offering more topology options. They are great for M2M and IIoT applications, including transportation and smart grid.
Network security is now more critical than ever before. The EW50 and EW200 both provide secure VPN remote connectivity using Ethernet, Wi-Fi, and Cellular IPSec, OpenVPN, PPTP, and L2TP VPN, with support for up to 16 concurrent tunnels with 70~100Mbps throughput. Additionally, SPI (Stateful Packet Inspection) and IPS (Intrusion Prevention System) firewalls provide added protection against network invasions. Dual SIM card slots in a single module provide a unique fail-over mechanism. If the cellular connection for the SIM card currently in use ceases, the device automatically switches over to the other card, which significantly reduces network downtime. Support for VRRP (Virtual Router Redundancy Protocol) further enhances the availability and reliability of the communications between remote devices.
