IoT Products

Smart Gateway the model R654G 4G Router is highly integrated wireless solution designed for SME, M2M and IoT applications like Remote Office, ATM and POS terminals, with support WSN IEEE 802.15.4.

The Smart Gateway has automatic WAN failover between several upstream connections WAN (Ethernet) and WWAN (3G/LTE). The core of the system is open source (based on OpenWRT). Commercial support and customization of the software is also available.

The functionality of the Smart Gateway can be extended via additional built-in modules like module VoIP with FXS port (with RJ11 soket), module WSN IEEE 802.15.4 and others.
