615M-1 and 645M-1 Cellular Modems & IP Routers

The ELPRO 615M-1 3G cellular modem and 645M-1 4G/LTE cellular modem are powerful Multi-Service Provider Cellular Broadband Routers that deliver wireless data connectivity for up to two LAN connections and one serial port through public cellular networks at 3G and 4G/LTE network speeds. UMTS technology leverages high-speed HSPA to provide data access at speeds up to 14.4Mbps with backward compatibility to GSM’s EDGE and GPRS. CDMA technology leverages high-speed EV-DO Rev A to provide data access at speeds up to 3.1Mbps with backward compatibility to EV-DO Rev 0 and CDMA 1 x RTT. It provides real-time redundancy between Carriers in case of a network failure, reliable connectivity for Programmable Logic Controllers (PLCs), Remote Terminal Units (RTUs), Ethernet web cameras or any other Ethernet connectivity device. The ELPRO cellular modems feature an integrated DHCP server, port forwarding and port mapping capabilities.

The perfect solution for remote monitoring and control of critical customer assets, using reliable and proven cellular network technology.
