Catalyst Receives SBIR Contract to Explore Broadband PTT Interoperability

The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) awarded a total of $4,479,195.95 in competitive research contracts to 30 small businesses across the United States to participate in phase one of the DHS Small Business Innovation Research (SBIR) program. These awards, which were competitively sourced, were developed in collaboration with program managers and stakeholders across DHS to address homeland security research and development needs.

Catalyst Communications Technologies received a contract to research the feasibility of a broadband push-to-talk (PTT) interoperability platform. Catalyst had previously been awarded contracts from DHS S&T in 2018 and 2020 to research and develop a platform for communications between LMR subscriber devices and smartphones on LTE networks, including FirstNet built by AT&T, using a standards compliant mission-critical PTT (MCPTT) application. With the proliferation of different PTT over broadband systems, there is now a need to research how these different LTE based systems might interoperate together.

“We have broad and significant domain expertise in the area of LTE and LMR technology and interoperability requirements, especially as a result of our 2018 and 2020 Awards,” said Catalyst President Robin Grier. “This award continues our commitment to develop technology in support of first responder communications and the needs of the mission critical communications marketplace.”

The award is a SBIR phase one award. At the completion of phase one, awardees will be eligible to submit proposals for a phase two award. The objective of phase two is to continue efforts to develop and demonstrate a working prototype.
