With the recent finalization of the IEEE's 802.16e-2005 standard and the upcoming test and certification of WiMAX products, mobile broadband services are becoming a reality. As an IP-based solution, mobile WiMAX technology will provide converged video, voice, and data services to mobile users. To investigate the capabilities and challenges of deploying a(More)
As the information needs and services of today's Armed Forces grow in size and complexity, providing the necessary transport networks to support broadband services becomes a significant challenge. This is especially true in tactical environments where warfighters often rely on low data-rate tactical networks or bandwidth-constrained terrestrial circuits for(More)
As the defense information systems network (DISN) transitions to a native-IP network supporting converged unclassified and secret data, voice, and video on the global information grid (GIG) backbone, an extensive quality of service (QoS) architecture will be required to effectively support real-time and mission critical traffic. Service level agreements(More)
The Defense Information Systems Agency (DISA) is operating as the Lead Service in the FY07 Joint Capability Technology Demonstration (JCTD): Tactical Services Provider (TSP). TSP will evaluate the ability of mobile broadband technologies to provide global communication capabilities to support widely dispersed warfighters on mobile and fixed platforms.(More)
The global broadcast service (GBS) provides a worldwide, high capacity, one-way transmission of classified and unclassified video, imagery, and other information as required to support joint military forces in garrison, in transit, and in theater, GBS enables real-time information product delivery to the warfighter by providing a combination of leased(More)
The Defense Information Systems Agency (DISA) is operating as the Technical Manager in the tactical services provider (TSP) joint capability technology demonstration (JCTD). TSP will evaluate the ability of mobile broadband technologies to provide global communication capabilities to support widely dispersed Warfighters on mobile and fixed platforms.(More)
Leveraging the Defense Information Systems Agency's (DISA) experience on the Tactical Services Provider (TSP) Joint Capability Technology Demonstration (JCTD), this paper analyzes the security weaknesses and vulnerabilities of mobile Worldwide Interoperability for Microwave Access (WiMAX) in the TSP architecture and explains DISA's approach to deploying an(More)
