MG102i wireless router securely and wirelessly connects two private networks/sites (e.g. Remote LAN and company Intranet) via public mobile networks and the Internet. The benefits of such Virtual Private Networks (VPN) are flexibility, security, cost-effectiveness and convenience.

MG102i is a GPRS/EDGE/UMTS/HSPA router and enables fast and secure data transmission between two sites. For the establishment of Virtual Private Networks (VPN) two different technologies are supported: IPsec and OpenVPN. For simple applications the use of Dynamic DNS or fixed IP addressing can replace the need of a VPN.

Multiple devices can directly be attached to the MG102i thanks to the integrated 5 port Ethernet switch/router. The dual SIM feature guarantees best availability of network connections. MG102i Software is based on well proven components including an Embedded Linux operating system and standard communication protocols.

The NTP server with GPS time allows precise time synchronisation in each remote location.

The addressed SCADA and telemetry serial protocols can by efficiently used over GSM networks. The MG102i Terminal server can communicate with a RACOM central device equipped with serial protocols, e.g. a RipEX. A hybrid network, where individual RTUs are connected either via MG102i (GSM) or via RipEX (UHF radio) to the same centre, is possible as well.

MG102i is a new product that extends HW and SW functionality of previous MG102 and is fully SW compatible with M!DGE routers.
