The Department of Homeland Security (DHS) is conducting a market survey to gather information on commercially available Mission Critical Push-to-Talk (MCPTT) systems through a Request for Information (RFI) issued by the National Urban Security Technology Laboratory (NUSTL). The objective of this RFI is to collect data that will inform the DHS Science and Technology Directorate’s System Assessment and Validation for Emergency Responders (SAVER) program, which aims to assist response organizations in selecting and procuring effective communication equipment. These systems are crucial for enhancing communication capabilities among law enforcement, fire personnel, and emergency medical services during critical operations. Interested vendors must submit their responses, including product specifications and company information, by October 5, 2024, and are encouraged to use the online Product Summary Questionnaire provided. For further inquiries, vendors can contact Gladys Klemic at nustl@hq.dhs.gov or Chase Knechtel at chase.knechtel@hq.dhs.gov.
