Innovation: GNSS Spoofing Detection

June 1, 2013By
In-opener

It's a hostile (electronic) world out there, people. Our wired and radio-based communication systems are constantly under attack from evil doers. We are all familiar with computer viruses and worms hiding in malicious software or malware distributed over the Internet or by infected USB flash drives. Trojan horses are particularly insidious. These are programs concealing harmful code that can lead to many undesirable effects such as deleting a user’s files or installing additional harmful software. Such programs pass themselves off as benign, just like the “gift” the Greeks delivered to the Trojans as reported in Virgil’s Aeneid. This was a very early example of spoofing. read more

Rohde & Schwarz, 7Layers Verify Improved Test Method for ECC

May 22, 2013By

Rohde & Schwarz and 7Layers have verified and validated the synchronized test approach to determine the Envelope Correlation Coefficient (ECC), a value characterizing the antenna subsystem of multiple-input and multiple-output (MIMO) LTE devices. The Synchronized ECC approach delivers significantly shorter test durations and repeatable results, ultimately resulting in reduced costs. Long term, this collaboration will also help product manufacturers develop... read more
