When it comes to life-threatening situations, it is an expectation of the population to be notified immediately via several contact paths. In the 2000’s as smart phones emerged and built market share, showing dominance would continue, Computer Aided Dispatch (CAD) 911 systems developed or integrated software solutions to improve 911 that allowed mass alerting to a geographic area or mapped area (map-based notifications). Such notifications are known as Amber Alerts or similar have a regional name such as “Alert Iowa” and can be state-wide and even city, county or municipality focused. Wide geographic areas and mass populations could quickly be notified of urgent and important information that impacted personal safety or assisted law enforcement. Or, citizens can now text 911 for help if they are not able to speak on the phone for some reason. Municipalities to include cities, towns, and counties have created citizen opt-in portals (via website or internet enabled signup) to help ensure that people sign up and receive these emergency notifications. Some of the large state-wide or national wireless emergency network alerts are opt-in through phone settings. However, it is not a surprise that many citizens (for local and regionalized alerts from 911 dispatch or emergency management) are ill informed about the need to proactively keep the cell phone carrier updated in the database, as text and SMS/MMS technology relies upon carriers receiving the information and then delivering the alerts to the citizen (enabled by cell towers and data plans). New technology through push notifications and cloud-based software as a s solution (SaaS) and mobile applications allows for just a one-time signup that stays with a designated cell phone despite their carrier. In addition, alerts are delivered via mass distribution at a higher guaranteed rate and speed of delivery due to cell phone tower limitations that exist when massive data stacks on towers. Reverse 911 systems should allow for both SMS/MMS/text delivery and push notifications and cross platform deliveries that could include robocalls and emails as well. Plus, there are additional advantages of mobile application based alerts that include citizens only getting alerts if they are in an impacted area or ‘geofenced’ area where a threat or impacted area is known to exist. Mass notifications historically have improved public safety notifications but the 2020’s have seen the evolution of new GPS enabled technology to ensure that citizens only receive on-the-go alerts regarding public safety when they are in an impacted area. Surprisingly, CAD 911 systems are still playing catchup and many 911 dispatch centers and communities or large groups/gatherings/hosts to large events do not know about this technology. The newest technology allows the incident commanders, management, or law enforcement with feet on the ground to actually get more assistance in protecting those impacted by clear and meaningful notifications to assist in evacuation, shelter-in-place or get assistance with things like assistance in finding a missing child at large public events. Notifications and alerts can even allow for those receiving the alert to be able to respond within a designated time period and see all updates in a feed within the app that do not disappear to help improve communication flow and improve outcomes for those impacted.
