QAM modulation available for the Satellar XT 5R/5RC

The new QAM variant of the Satellar XT5R modem is now available.

QAM modulation (phase and amplitude modulation) improves performance and radio sensitivity in tricky environments with multiple radio paths and returns.

With this new modulation, the available radio rates are up to 121 Kbps for a 25 kHz channel !

CityMobil2 at La Rochelle

Committed to the European project CityMobil2, the Agglomeration of La Rochelle successfully completed in 2015 a demonstrator with 6 8-seater electric vehicles without driver.

Comatis acted in partnership with the Agglomeration by providing the two radio solutions allowing the precision positioning of vehicles and the crossing of traffic lights in autonomous mode (without human intervention).

Precision positioning is made possible by radio transmission of RTK corrections ensuring sub-metric accuracy.

Crossing of the intersections works by issuing requests for the passage of vehicles accompanied by authorization information from the traffic light controllers.

Comatis was naturally asked for this operation given its position as supplier of the bus priority solution at the La Rochelle traffic lights, in place since 2009.

AES128 Encryption for Satelline Easy.

AES128 encryption is now available across the entire range of Satelline Easy Modems.

Specific encrypted models of modems now have this new feature :

  • SATELLINE-M3-TR1
  • SATELLINE-EASy with and without display
  • SATEL EASy-Proof
  • SATELLINE-EASy Pro

The use of encryption on the radio interface ensures that only the receiver authorized to access the data sent is able to receive and read this data.

Satel offers more security to your communication network!
