FOREWORD

The National Urban Security Technology Laboratory (NUSTL) is a federal laboratory organized within

the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T).

Located in New York City, NUSTL is the only national laboratory focused exclusively on supporting

the capabilities of state and local first responders to address the homeland security mission. The

laboratory provides first responders with the necessary services, products, and tools to prevent,

protect against, mitigate, respond to, and recover from homeland security threats and events.

NUSTL manages the System Assessment and Validation for Emergency Responders (SAVER)

Program, which conducts objective assessments and validations on commercially available

equipment and systems and develops knowledge products that provide relevant equipment

information to the emergency responder community. The SAVER Program mission includes:

• Conducting impartial, practitioner-relevant, operationally oriented assessments and

validations of emergency response equipment.

• Providing information, in the form of knowledge products, that enables decision-makers and

responders to better select, procure, use, and maintain emergency response equipment.

SAVER Program knowledge products provide information on equipment that falls under the

categories listed in the DHS Authorized Equipment List (AEL), focusing primarily on two main

questions for the responder community: “What equipment is available?” and “How does it

perform?” These knowledge products are shared nationally with the responder community,

providing a life- and cost-saving asset to DHS, as well as to federal, state, and local responders.

NUSTL is responsible for all SAVER activities, including selecting and prioritizing program topics,

developing SAVER knowledge products, coordinating with other organizations, and ensuring

flexibility and responsiveness to first responder requirements.

NUSTL provides expertise and analysis on a wide range of key subject areas, including chemical,

biological, radiological, nuclear, and explosive weapons detection; emergency response and

recovery; and related equipment, instrumentation, and technologies. In support of this tasking,

NUSTL conducted a market survey of mobile messaging applications for first responders. Mobile

messaging applications fall under AEL reference number 13IT-00-ALRT titled “System, Alert/

Notification.”

EXECUTIVE SUMMARY

Smart phones and other mobile devices are ubiquitous in our society. First responder agencies are

increasingly adapting and implementing mobile technologies into their day-to-day operations, in

part because these devices can increase their capabilities in two critical domains: situational

awareness, and communications and information sharing.

This market survey report contains 23 different mobile messaging applications that could

potentially be leveraged by first responders when responding to incidents and emergencies. Some

of these applications were developed with first responders explicitly in mind as the primary end

users, while others, developed for the broader consumer marketplace, may also lend themselves to

first responder applications.

When searching for a mobile messaging solution to enhance situational awareness, communication

and information sharing in a secure and reliable manner, first responder organizations have many

viable options to explore and from which to select a tool that meets their specific needs.

1.0 INTRODUCTION

Law enforcement departments across the country are beginning to use smartphones and mobile

messaging apps with the goal of augmenting the safety and efficiency of their operations. The

Boston Police Department (BPD) requested assistance from the Department of Homeland Security

(DHS) Science and Technology Directorate (S&T), National Urban Security Technology Laboratory

(NUSTL) in exploring mobile messaging applications (herein also “mobile apps,” “messaging apps,”

or simply “apps”) with potential to support incident response and management in the Boston

region.

Currently, some first responders are not equipped with a dedicated, text-based messaging platform

while on the job. These personnel must communicate location positions and other critical

information over the radio. Reliance on radio, however, limits the first responders’ ability to quickly

share photos, maps, and location information all at once.

This market survey identifies messaging apps that enable first responders to send information such

as messages, alerts, images, and locations between field operators using mobile devices and

officers stationed at static locations (such as an incident command location or headquarters

building) who are using desktop computers.

NUSTL performed due diligence to develop a report that is representative of products in the

marketplace. To provide the BPD and other agencies with information on commercially available

mobile messaging apps, NUSTL posted a request for information (RFI) on the federal business

opportunities website (fedbizops.gov) and requested a technology scouting report from the

Technology Scouting Branch within DHS S&T [1]. From October 2019 through January 2020, NUSTL

also gathered information using internet research, industry publications, consultations with subject

matter experts, and subsequent contacts with mobile messaging app developers in order to

produce this market survey report.

Solutions that fall into the category of “mobile messaging applications” generally have a few

relevant features in common:

• Users can share written text-based messages

• Users can share image messages

• Users can share multimedia messages such as audio and video recordings

• Exchanging messages relies on wireless networks and standard information exchange

protocols (e.g., Wi-Fi, TCP/IP, fourth generation long term evolution (4G LTE), short message

service (SMS), multimedia service)

The mobile messaging apps included in this market survey report contain the features mentioned

above, as well as two additional features of particular importance to first responders as detailed in

the next section.

2.0 MOBILE MESSAGING APPLICATIONS OVERVIEW

Smart phones and other mobile devices are ubiquitous in everyday society. First responder

agencies increasingly adapt and implement mobile technologies into their day-to-day operations, in

part because these devices can increase their capabilities in two critical domains: situational

awareness and communications and information sharing.

According to “Project Responder 5” [2] “Situational Awareness” is the capability to provide and

distill specific knowledge concerning emerging threats, hazards, and conditions in a timely fashion

to support incident management decisions across all phases of incident response.

“Communications and Information Sharing” is the ability for both the on-scene responder and

incident command to access, integrate, and display images and video from the incident scene.

2.1 PRIORITY FEATURES FOR FIRST RESPONDERS

Based on conversations with first responders, mobile messaging app features that are particularly

important to their work include, but are not limited to:

• Multimedia sharing – messaging app solutions able to send pictures (like .jpg and .png),

videos (such as mp4), and audio files (for example, mp3) between users

• Location sharing – messaging app solutions able to share the location of users to other

users also on the app’s platform

• Auditability – messaging app solutions able to be audited for both training purposes, after-

action reviews, and meeting legal or regulatory requirements

An effective mobile messaging platform would enable first responders to send location maps,

pictures, and other real-time alerts instantaneously to an entire first responder team. Users could

actively track the locations of other officers on duty, analyze pictures with layered information, and

stay abreast of unfolding situations through mass alerts. As a result, the messaging application

would enable the advanced coordination needed for first responders to manage large-scale events.

The application would also allow incidents, responder communications, and actions taken to be

revisited.

2.2 FIRSTNET

First responders may also access a priority network while using mobile messaging applications—a

matter of devices (hardware), not just applications (software). While using a particular software

solution can boost capacity for situational awareness and information sharing, using hardware

compatible with FirstNet can boost communications reliability as well as expand the range of

mobile applications available.

In 2012, Congress established FirstNet, a nationwide broadband network dedicated to first

responders – a response to the diminished communication capabilities first responders

experienced during 9/11 due to network congestion. During any incident with high-traffic network

activity, first responder devices connected to the FirstNet network receive priority for text and voice

communication, through a mechanism called “priority and pre-emption.”

Approved for Public Release

Public safety devices will gain access to the network first, network resources will not be taken away

from public safety devices and in some severe cases commercial users may be momentarily

disconnected from the network. Thus, emergency and security personnel can handle large-scale

situations without compromised communication abilities.

In addition to providing voice, data, and messaging services, FirstNet hosts an app catalog that

features software and apps tailored to the needs of first responders. [3] The solutions offered for

first responders range from communication apps, fleet management software, and push-to-talk

communications to cloud storage options and device security solutions. Apps are vetted by FirstNet

to ensure developers are following industry best practices. In addition, during times of network

congestion, traffic on apps from the FirstNet catalog receives priority connection versus publicly

available apps. Supervisors and chiefs can apply for FirstNet network access, devices, rates, and

(once connected) its app catalog.

This report, however, does not address solutions available only in the FirstNet catalog. This market

survey focuses on commercially available messaging applications, but notes when an application is

compatible with FirstNet for readers who may be interested in taking advantage of its network

prioritization features.

Both iOS and Android devices may be compatible with FirstNet. FirstNet-certified hardware,

however, is not limited to mobile smart phones. A full list of certified FirstNet devices is available

from the National Institute of Standards and Technology [4].

informed event response. Since being used in

overseas military operations, ATAK-Civ has been

modified for domestic use by federal, state, and local

police departments and first responders. Through

ATAK-Civ teams can track and mark on maps the

locations of team members, incidents, and threats for

enhanced team situational awareness. The app

enables users to chat and share files through either

user-to-user or user-to-teams communication

channels. Recently, a new universal push-to-talk plugin for ATAK was developed that uses Mumble,

an open-source backend. The Team Awareness Kit (TAK) can be considered as a suite of services

across different platforms that are interoperable. It includes, ATAK-Civ, WinTAK-Civ a Windows

based TAK client, and TAKServer which can be used by all TAK clients to coordinate information.

3.3 BRIDGE4PS – MOBILITY4PS

collaborate on shared floorplans, images, and maps. It

is a part of the FirstNet app catalog.

3.6 ESCHAT – SLA CORPORATION

ESChat is a solution that supports secure group

messaging for texts and images. ESChat’s desktop and

mobile interfaces allow dispatchers and supervisors to

both communicate with officers in the field and track

their locations live. The app also supports historical

location tracking so first responders can pinpoint their

location on a map at configurable intervals to leave

“breadcrumbs” with a date, timestamp, as well as the

speed and direction of the user when the location pin

was dropped. In addition, administrators can choose to

store the chats on the ESChat server for later audits.

3.11 IMESSAGE – APPLE

iMessage is the native texting and instant messaging platform installed on iPhones. Users can send

messages, photos, videos, and location pinpoints to each other using Wi-Fi or data. Viewable in the

“Find My” app, iMessage shares a user’s location with other iPhone users in real time. That location

data, however, is not stored so it is not available for later review. This app is only available on

desktop for macOS users; there is no web browser version. Also, of note, there is no enterprise

platform for iMessage, making after-action audits difficult.

3.12 INTREPID RESPONSE PLATFORM – INTREPID NETWORKS LLC

The Intrepid Response Platform is a first responder communication platform for both the web and

iPhone and is available only through the FirstNet app catalogue. The app supports group or person-

to-person chats that include photo and video sharing. The map feature of the app provides live GPS

iOS devices, allows officers to create chat groups or directly

message individuals. First responders are able to view the

locations of others with GPS location tracking in real time.

Dispatchers and supervisors can communicate with

officers in the field by using Orion’s Dispatch Console. This

app was created for workforce coordination but has first

responder applications due to its location tracking and

chat capabilities.

3.15 PUBLICEYE – ZCO CORPORATION

PublicEye is a collaborative app created specifically for public safety workers. It supports text,

audio, and video chatting. In addition, it supports ESRI map integration, allowing officers to mark

incidents and create real-time alerts for other members of their unit. PublicEye is also able to

monitor social media surrounding a specific crime scene for additional, nearly real-time

information. PublicEye is operable on Android and iOS mobile devices and desktop computers.

3.16 SIGNAL – SIGNAL FOUNDATION

Signal is an end-to-end encrypted instant messaging platform that has both a mobile and desktop

interface, allowing officers in the field and commanders at the station to communicate on the same

platform. Signal, being an end-to-end encrypted application, is not an easily auditable platform. In

fact, one key feature allows users to set messages to disappear. This could cause an issue

regarding data retention regulations.

3.17 TEAMS – MICROSOFT

Teams is an instant messaging platform on which users can send messages, photos, videos, and

host audio/video conferences on both desktop and mobile devices. Teams allows users to create

both group chats, individual instant messages, teams and channels. In addition, first responders

can share their locations but must manually send updates when they move to a new location.

Administrators of Teams can set the server to archive all chat history, which allows for after-action

audits when needed. Teams also allows integration into other Microsoft products and services such

as Office 365.

chats for sharing photos, videos, location pinpoints, and

documents. This application also has a one-way

information channel “broadcasting” function that chiefs

can use to push out announcements and alerts. Teamwire

has both a mobile app and a desktop interface so

supervisors can communicate with officers in the field.

3.22 WHATSAPP – FACEBOOK INC.

WhatsApp is a free, instant messaging app used primarily by private users. Users can send

messages, photos, and videos on both desktop and mobile devices. In addition, users can manually

send their location in group or individual chats. Other options include sharing one’s live location or

simply a location pinpoint. There is no enterprise subscription or administrative role through the

app, however, making after-action audits difficult.

5.0 SUMMARY

This market survey report provides information on 23 different mobile messaging applications that

could prove useful when coordinating responses to incidents and emergencies. The apps provide a

variety of mechanisms for increasing situational awareness across first responder teams and

organizations engaged in time-sensitive operations.

Some of these mobile technology solutions were developed with first responders explicitly in mind,

including some that are compatible with or only available through the FirstNet communications

network. Other messaging apps reviewed herein were developed for the broader consumer

marketplace yet may lend themselves to first responder applications. The products vary in

important areas such as ease of use, reliability, and ancillary features—including key features for

first responder organizations such as multimedia messaging, location sharing, and auditability.

There are many viable solutions for first responders to explore, making it possible for organizations

to select the application that best meets their needs for enhancing communication of incident

information and situational awareness in a secure and reliable manner.
