RadioResource has an article on DHS’ collaboration with the NYPD on their test and evaluation of ATAK for Emergency responders, also integrating with another licensee, Persistent Systems.
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) First Responder Group (FRG) examined two communications technologies and evaluated them for public-safety use.
FRG evaluated the Mobile Ad-hoc Networking (MANET) system, a communications system originally developed for military use, and an Android Tactical Awareness Kit (ATAK) to determine if they could improve communications and public-safety situational awareness.
FRG conducted a field test in collaboration with the New York City Police Department’s (NYPD) Emergency Service Unit (ESU) and with technical assistance from S&T’s partners Johns Hopkins University Applied Physics Laboratory (JHU/APL) and Persistent Systems. Earlier MANET systems proved to be effective to address mission-based communications needs for the U.S. military and other DHS components, such as the U.S. Border Patrol. DHS S&T is exploring this capability with the NYPD to overcome factors such as wireless coverage dead spots and service congestion associated with existing network infrastructures.
“Ensuring our public-safety agencies have the necessary technologies to share interoperable voice, data and video during an emergency remains a top priority for DHS,” said Cuong Luu, S&T program manager for the MANET project. “By testing systems in operational environments, we can observe how equipment supports the mission-specific needs of local law enforcement agencies and help determine its communications range capabilities for supporting voice, video and geographic location capabilities in a complex urban environment.”
The main component of the MANET system, the Persistent Systems’ MPU5 Smart Radio (MPU5), can be used to transmit data, video and voice communications between several radio nodes and can augment LMR communications and cellphone networks as necessary. It can also be used with various accessories, including antennas and can withstand extreme temperatures, as well as water immersion, shock and salt fog.
The ATAK is an Android application developed by the Air Force Research Lab that shows the geographic location of all MPU5 nodes on the network and provides text, chat, video and picture-sharing capabilities on a moving map display.
The field test took place at two venues in New York’s Times Square: the Marriott Marquis Times Square and the Times Square subway station. The NYPD ESU participants use an LMR network with one citywide repeater frequency and three point-to-point frequencies with limited encryption mechanisms available. These frequencies allow only for voice communications. With responders walking through a realistic scenario for the field test, they evaluated the MANET system’s ability to enhance their situational awareness by providing location and real-time video streams in addition to voice.
The feedback during the field test was largely positive. Participants appreciated the software tool’s ability to provide video streaming and live location updates of each personnel. The tool augmented voice communications because the team could see locations on a map, along with a live video stream from the team lead.
“Having the ability at the mobile command vehicle to view a live video feed improves our situational awareness because the video can augment our voice communications,” said Detective John McKenna of NYPD ESU.
These types of field tests also allow responders to provide input into improvements and modifications to allow the equipment to meet specific mission-based needs. For example, because the MANET system requires several radios to comprise a mesh network with multiple radios serving as relay nodes, and it is not feasible for NYPD personnel to carry radios for the sole purpose of serving as relay nodes, participants suggested using drop boxes such as pelican cases with radios pre-loaded as the relay points.
S&T will publish an-after action report in the coming months summarizing the field test details, findings and lessons learned.
