IP gateways for remote locations
Advantech's GPRS IP gateways, the EKI-1321 and EKI-1322, are designed for use in remote locations and feature two SIM card slots and allow the user to create a secure virtual private network (VPN).
Advantech's GPRS IP gateways, the EKI-1321 and EKI-1322, are designed for use in remote locations.
To get the best possible connection, these devices include two SIM card slots to be able to choose two service providers to transmit the data. The devices will automatically switch between the SIM cards to gain the best possible signal and transmission rate. During this switch, the serial data being transmitted will be either buffered in the memory or stored on an SD card where it will be sent on when the signal resumes.
To remotely use the gateways, they feature has the Reverse Virtual COM, which allows the gateways to automatically connect to a server if a public IP address is used.
For users to be able to create a secure virtual private network, the gateways include support for the OpenSource VPN software OpenVPN, which uses RSA Asymmetric Encryption technology with key sizes up to 4096 bits.
To future-proof the gateways, they can used either with IP version 4 or version 6. IP version 4 is still the most common but version 6 is becoming more widely adopted. If a customer's network does make the change, the gateways are easily reconfigured. They both have passed the phase-2 approval of IPv6 Ready Logo Committee.
