Research and Teaching Laboratories

The Applied Communications and Information Networking Center
The ACIN Camden Center, Camden, NJ; Dr. Moshe Kam, ACIN Program General Manager; Dr. William Regli, Dr. Kapil Dandekar: Principal Research Invesigators

The focus of the ACIN Camden Center is on the creation and demonstration of
innovative telecommunications and information networking technologies; and
the demonstration of proofs-of-concept for: secure, reliable, user-centered,
wireless communication and networking platforms that leverage these
technologies.

These platforms will support network-based end user applications that end
users can depend upon, in critical missions and operations... where these
networking platforms may be severely stressed or limited by environmental
factors; and where these networks may be under attack by adversaries,
including criminals and terrorists.

Current projects focus on wireless communication in non-line-of-sight
environments using various advanced technologies that employ relaying and
multipath diversity; and the creation of secure, wireless networks to
support teams of users conducting emergency operations.
