iSat: Case studies for the Romantis satellite router

iSat designed networks using Romantis modems

This week iSat configures a Romantis satellite router to offer more functionality and flexibility than any comparable technology. Get more for less!

Context
A mining company in an African country wants to connect its HQ in the countries capital with four remote sites that use satellite. The in-country regional hub has a 2.4mtr, and 1.8mtr is desired at remote sites to keep transport costs down. The M&C supervision and international connection is through a European based hub.

The in-country hub uses highly efficient DVB-S2 to download the 2Mbps into the remotes and supervisory site.
The return carriers use the “Full Mesh” feature to connect the two hubs, but VLANs prevent remotes talking to each other.
The remotes and supervisory hub are using both their DVB-S2 and TDMA receivers. All traffic is single hop. The in-country hub is timed by the Master Mesh unit residing in the supervisory hub. Telnet is available, so even if contact is lost through one receiver, the unit can be recovered through the other.
One single hardware platform serves a spare for a modem however its configured.
