EADS Secure Networks Successfully Demonstrates Multi-Vendor, System of Systems Radio Interoperability EADS Collaborates With General Dynamics and M/A-COM in P25 ISSI Interoperability Demonstration Friso, TX , January 16, 2007 - As the first in the industry to successfully demonstrate the P25 Inter-RF Subsystem Interface in August 2006, EADS Secure Networks North America, Inc., a subsidiary of EADS North America announced today that it has now successfully interoperated with a different manufacturer’s P25 network in an independent lab led by General Dynamics C4 Systems. EADS Secure Networks, which markets IP-based, mission critical radio systems based on the P25 Open Standard to Public Safety and First Responders in the North America, worked with General Dynamics and M/A-COM on December 1st at the General Dynamics Homeland Security System Development Laboratory in Scottsdale, Arizona to demonstrate the real-time, comprehensive radio communications interoperability that public safety officials and first responders are seeking. Following EADS’ successful launch of their P25 ISSI solution, General Dynamics requested that EADS collaborate with M/A-COM to create a live demonstration of the powerful abilities of open standards-based radio interoperability. Two key demonstrations took place: 1) network level interoperability between P25 system from different manufacturers and 2) units roaming from their “home” system and being able to talk on the system they are “visiting” with connectivity back to their home system. Today’s public safety and homeland security challenges demand that radio networks be united to enable law enforcement, fire, EMT, and other first responders to support each other regardless of geographic boundaries,” said David Cerqua, General Manager of EADS Secure Networks. “This test validates the P25 ISSI Standard and proves absolutely that the technology is in place and ready to support these requirements without the need for expensive or proprietary gateways.” The demonstration used the recently passed Association of Public Safety Communications Project 25 (P25) Inter-RF- Subsystem Interface (ISSI) standard to enable the two systems to interoperate at the network level, rather than only over-the-air. “For nationwide law enforcement and homeland security applications such as the U.S. Government’s Integrated Wireless Network (IWN), meeting the standards for interoperability is a priority,” said Lee Wright, director of National Communications and Homeland Security for General Dynamics C4 Systems. “Recognizing the growing importance and potential of enabling agency responders to communicate securely anywhere, General Dynamics made a significant investment in the laboratory in order to advance standards-compliant radio interoperability.” EADS and General Dynamics will continue collaboration on interoperability testing. In addition, EADS continues to validate other manufacturer’s P25 radios, equipment and software applications on its P25 radio architecture as part of its commitment to delivering mission critical radio systems for public safety built for today and tomorrow.
