Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; this brings a bright future for GPRS data networks applications.Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones.
Ethernet is migrating from traditional IT equipment and being adopted as a standard interface for many types of machines, however challenges arise at customers sites where the LAN infrastructure is outside your control.
The wireless router creating a standalone network, where access to attached LAN-based devices is gained over wireless network for control and monitoring purposes.
The H685g GSM Router is easy to install reducing the reliance on the end customer and enables direct access to your remote LAN devices for control and monitoring purposes.
It enables companies to remotely access equipment at mobile, remote networks and isolated sites.
GPRS Router offers wireless network routing optimised for machines, small networks and specialised Fixed IP services now available from wireless operators. It offers low cost router operation through Dial-out, Dial-in and Always Connected modes of operation.
H660g key feature:
WAN (xDSL) and GPRS backup each other
Dual SIM with dual mode backup each other
Dual SIM work together to bind the two network to increase the speed.
