The Teleterm M3 RTU now boasts a satellite communications option to the Omniflex Web based Data2Desktop Datacentre. The satellite has access to hard to reach locations, with limited infrastructure.

Remote Monitoring requires the usage of the most suitable communications infrastructure available at the remote location. While GSM networks are ubiquitous they do not provide complete coverage whereas satellite coverage is essentially global.  The Teleterm series has now added Satellite communications to its list of remote monitoring options.
