DENVER, May 7, 2019 -- 5G’s characteristics sound promising for first responders, but what is the best path for public safety to take as it tries to get there? Join S&T Panelist Cuong Luu to learn how the evolution from 4G to 5G will differ significantly from previous generational transitions in the wireless industry, and what that will mean to public-safety agencies, in terms of short-term buying decisions and long-term strategies. This panel will be held in the Expo Theatre: IWCE Public Safety Summit, from 2:35-3:10 p.m. at the Colorado Convention Center.
DHS S&T is showcasing technology advances, program impacts, investments, and emergency communications solutions at this year’s International Wireless Communications Expo.
Since 2012, S&T has funded academic research to improve the WEA technology focused on how the public responds to alerts and warnings, and enhancement of WEA’s geo-targeting capabilities.
This test report documented ViSi Mobile’s value in improving basic life support medical care. ViSi Mobile achieves its goal of reducing entanglement and eliminating the need to constantly connect and disconnect to different vital signs monitoring systems. It also possesses the potential to continue to grow and improve to incorporate additional future capabilities such as defibrillation.
A significant long-standing challenge for imminent threat alert originators (AOs) at all levels of government is how to quickly communicate warning messages to people in danger, while avoiding to warn those not at risk. Providing effective warnings of an imminent threat, such as a dangerous tornado, can save lives. Ideally, people can take shelter before the tornado strikes if they are provided enough warning time.
Effective alerts and warnings during a disaster protects people and saves lives. Over the past decade, mobile communication technologies have become ubiquitous. Disaster and emergency messages sent directly to end users has emerged as a promising new practice. In particular, short message service (SMS) text message formats have emerged as a modality that is both practical and popular as the majority of Americans now use smartphones. In regards to Department of Homeland Security (DHS) wireless emergency alerts (WEAs), these messages are pushed out through commercial mobile carriers to customers who are located geographically near the hazard, and newer smartphones are ‘WEA enabled.’
With increased risk and financial impacts from different hazards in recent years, building community resilience through public and private stakeholder participation has become a priority for researchers and policy makers (Cutter et al. 2008; NRC 2012). Risk communication has been identified as a crucial component of community resilience-building efforts, and a precursor to undertaking disaster risk reduction initiatives during different phases of emergency management (Mileti and Peek 2002; Morgan et al. 2002; Hooke and Rogers 2005; Fischhoff 2009). The Sendai Framework for Disaster Risk Reduction 2015―2030, a recent United Nation’s initiative to build resilience and a successor to the Hyogo Framework for Action (HFA) 2005―2015, has also identified the need to develop, maintain and strengthen a multi-hazard, multi-cultural and people-centered forecasting and early warning system for disaster risk communication (UN 2015).
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) envisions a future where all Americans are able to receive accurate alerts and warnings, regardless of communications technology used. This vision is being achieved through the Federal Emergency Management Agency’s Integrated Public Alert and Warning System (IPAWS). IPAWS is a modernization of the nation’s alert and warning infrastructure, integrating new and existing public alert and warning systems and technologies. In partnership with DHS Science and Technology Directorate (S&T), IPAWS is working to incorporate alerts to mobile devices through Wireless Emergency Alerts (WEA), formerly known as the Commercial Mobile Alert Service. This inclusion is an acknowledgement of the important role wireless technologies play in Americans’ lives today. Given the wide use of wireless mobile devices, WEA ensures more people can receive actionable alerts to help avoid danger or respond more quickly during crises—thereby saving lives and property.
The goal of this project is to characterize risk perception and response to a designated hazard.
This document describes research being done on a new Wireless Emergency Alerts (WEA) geotargeting mechanism by the Johns Hopkins University Applied Physics Laboratory (JHU/APL). This work was undertaken with the support of the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T). The WEA service provides the ability to send geographically targeted text alerts to the public. However, the current WEA geotargeting mechanism is limited by the relatively coarse granularity of cellular network sites. JHU/APL investigated methods of improving the geotargeting accuracy of WEA.
