Office for Interoperability and Compatibility

Office for Interoperability and Compatibility

The Office for Interoperability and Compatibility (OIC) provides local, tribal, territorial, state and federal stakeholders with the tools, technologies, methodologies and guidance to enable improved communications interoperability at all levels of government. OIC manages a comprehensive research, development, testing, evaluation and standards program to enhance interoperable emergency communications.

Emergency responders—police officers, firefighters, emergency medical technicians—need to share vital voice, video and data information across disciplines and jurisdictions to successfully respond to both day-to-day incidents and large-scale emergencies. Unfortunately, for decades, inadequate and unreliable communications systems have compromised their ability to perform mission-critical duties. Responders often have difficulty communicating when adjacent agencies are assigned to different radio bands, use incompatible proprietary systems and infrastructure or lack adequate standard operating procedures and effective multi-jurisdictional, multi-disciplinary governance structures.

OIC executes activities across two portfolios: Voice, Video and Data Communications and the Responder Technology Alliance. The Voice, Video, and Data Communications portfolio addresses the means through which first responders send and receive information. The Responder Technology Alliance (RTA) portfolio aims to develop integrated systems that improve first responder safety and effectiveness. Further, RTA leads visioning, planning and management of homeland security industrial base and venture capitalist initiatives to enable collaborative commercialization of technologies.

OIC supports the capacity for increased levels of interoperability by developing tools, best practices, technologies and methodologies that emergency response agencies can immediately put into effect. OIC is committed to working in partnership with all stakeholders to address critical emergency response communication needs with programs that advocate a “bottom-up” approach.

Our Projects


The datacasting technology provides public safety users with the capability to transmit secure data, including voice, text, files, images, and video over existing broadcast television signals to a targeted audience. It is a reliable tool to get first responders connected so they have the situational awareness and information they need to make informed decisions when responding to an incident.

Project 25 Compliance Assessment Program (P25 CAP)

Communications equipment manufacturers often use different technical approaches that have the potential to leave their products incompatible. P25 CAP provides first responders with summary test reports and declaration of compliance documentation from suppliers. This information ensures equipment complies with P25 standards and ultimately reduces waste and poor investments in untested equipment.

Video Quality in Public Safety (VQiPS)

VQiPS develops assessment tools and guidance documents that enable first responder agencies to purchase and deploy appropriate video technology to meet their operational needs. Purchase and deployment of systems by first responder agencies in accordance with VQiPS guidance will enhance video system interoperability within and across agencies. VQiPS coordinates disparate video standard development efforts and ultimately arm public safety consumers with the knowledge they need to purchase and deploy cost-efficient, interoperable video systems.
