Cell Broadcast-Based Public Warning Systems – An Effective Solution for Emergency Alerts

BELLEVUE, Wash. – July 24, 2018 – Cell broadcast-based Public Warning Systems (PWS) is currently the most effective technical solution for large group emergency notifications above other alerting methods in the Americas according to a new report from 5G Americas, the industry trade association and voice of 5G and LTE for the Americas. 5G Americas announced their publication of Public Warning Systems in the Americas whitepaper that elaborates on the benefits of cell broadcast-based Public Warning Systems that have been specified by the Third Generation Partnership Program (3GPP) and standardized by multiple Standards Development Organizations throughout Europe, Asia, and the Americas.

The paper by 5G Americas confirms that it is more beneficial for the general public to use cell broadcast-based PWS as opposed to point-to-point alerting methods such as Short Message Service (SMS) and Over-the-Top (OTT) applications to provide wireless emergency alerts. Cell broadcast-based emergency alert communication has advantages over for point-to-point methods including:

  • There are typically no significant delivery delays when attempting to deliver messages to a large number of recipients in a short period of time due to the underlying broadcast technology
  • There is no cell broadcast subscription required for receiving emergency alerts via cell broadcast technology
  • Messages are broadcast to all devices within a specific alert area, so if a user roams into a cell site in an alert area, the user will receive the alert
  • Smartphone subscribers do not require a data services subscription with their wireless operator in order for their device to receive an emergency alert via cell broadcast

Chris Pearson, President, 5G Americas commented, “Successful emergency warning communications systems are essential in today’s society when the impact of monumental disasters can be lessened by proper advance notification to people. Several countries in the Americas region have deployed and are actively working towards developing cell broadcast-based public warning systems, built upon the industry-wide 3GPP standards, which offers the best technical option for providing a safety net in the event of emergencies.”

Key challenges for SMS and OTT smartphone applications in providing emergency alerts include: possible delivery delays when attempting to provide messages to a large number of recipients in a short period of time; alerts are addressed to phone numbers in a chosen cell site area rather than users in the cell site alert area meaning not all users will receive alerts; SMS could possibly be spoofed by hackers; smartphone users must have a data service subscriptions to receive alert notifications via the cellular network on smartphone apps. Cell broadcast-based systems are effective in most all the challenged areas for SMS and OTT apps meaning any user in the geo-targeted area will typically be able to receive the alert.

“There is a tremendous benefit for countries to deploy the cell broadcast-based warning system so that any user can roam to any country and be able to receive wireless emergency alerts in a time-sensitive manner,” noted Jose Otero, Director of Latin America and the Caribbean, 5G Americas and also the author of this paper. “There remain some challenges to overcome in order to promote seamless international roaming such as the use of different applications in countries, different languages, and even the use of different ringtones, alert banners and character sets.”

The goal of the 5G Americas whitepaper is to inform and educate vendors, operators and regulatory authorities of the benefits associated with the cell broadcast-based system, explain and compare PWS and other alert systems in the Americas and describe the international roaming support for PWS. The paper will provide an understanding of varied emergency alert systems currently in use throughout the Americas, including details on emergency alert systems in many countries in the Caribbean and Latin America as well as Canada and the U.S.

Public Warning Systems in the Americas was written by a working group at 5G Americas under the leadership of Orlett Pearson of Nokia and Peter Musgrove of AT&T as well as representatives from member companies of 5G Americas who participated in the development of this whitepaper. Public Warning Systems in the Americas is available for free download on the 5G Americas website.

RO-ALERT – Cell Broadcast

Sistemul de avertizare RO-ALERT va fi testat Miercuri, 27 iunie 2018 in Bucuresti

Sistem de avertizare RO-ALERT

ISGU, Inspectoratul General pentru Situatii de Urgenta, a anuntat oficial astazi ca sistemul RO-ALERT va fi testat in anumite zone ale capitalei Miercuri, 27 iunie 2018. Ulterior sistemul de alertare va fi extins si la nivel national.

Conform autoritatilor, pe device-urile conectate la retelele operatorilor telecom din Romania va aparea mesajul: ”Acesta este un mesaj pentru testarea sistemului RO-ALERT. Nu se impune aplicarea măsurilor de autoprotecţie. DSU-IGSU”.

Sistemul de avertizare a fost implementat de catre Ministerul Afacerilor Interne, prin DSU şi IGSU, cu suportul tehnic al Serviciului de Telecomunicaţii Speciale si permite transmiterea mesajelor de tip Cell Broadcast destinate avertizării şi alarmării populaţiei în situaţii de urgenţă, pentru adoptarea comportamentului necesar autoprotecţiei, în caz de urgenţă majoră.

Smart provides communications equipment to support disaster preparedness efforts

Philippines’ mobile operator Smart Communications has provided communications equipment to the National Disaster Risk Reduction and Management Council (NDRRMC). The government disaster agency can now access Smart’s Emergency Cell Broadcast System (ECBS) and use it to quickly send public warnings to mobile phone users in specific areas.

The ECBS is designed to send urgent messages, such as evacuation notices and earthquake and tsunami warnings to activated mobile devices within the affected area. According to Smart, cell broadcast is effective in disseminating quick hazard alerts because it operates on a radio channel separate from those used by voice calls and text messages or SMS, which may get congested in times of calamities.

NDRRMC, the National Telecommunications Commission, and Smart, launched ECBS on a trial basis in March 2017. It has since been used to broadcast quick alerts during typhoons and post-earthquake situations. Most recently, ECBS messages were sent to Albay residents in the wake of the eruption of the Mayon Volcano. During this trial period, the alert messages were sent by the NDRRMC to Smart which then transmitted the messages. With the turnover, NDRRMC personnel will be trained on how to use the equipment to send out messages themselves, Smart also said.

Cell Broadcast Canada – Emergency Alert

What you need to know about the new mandatory alert system

‘It won’t be just a sound, it will come with some information as well’

Nearly all Canadians will receive mandatory emergency cellphone alerts starting April 6 to warn people across the country about impending dangers and threats, including natural disasters and terrorist attacks

“When you hear that tone, it means that there is an emergency that needs immediate action,” said Scott Shortliffe, chief consumer officer at the CRTC, which is mandating the change.

“It won’t be just a sound, it will come with some information as well.”

The ominous alarm will go off during an emergency, including Amber Alerts, forest fires, natural disasters, terrorist attacks or severe weather.

Shortliffe explained to CBC Radio’s Ottawa Morning Thursday how the new system, compatible with all wireless devices on LTE networks, will work in Ottawa.

Here’s what he told Ottawa Morning host Robyn Bresnahan.

Answers have been edited for length and clarity.

‘Imminent danger to life and limb’

Q: Who is going to get this alert?

A: Most Canadians will get the alert on their phones. There’s not a precise tracking of how many Canadians have LTE phones … but we know that 98.5 per cent of Canadians can receive [the alerts].

We [also] know over 87 per cent of Canadians have cell phones.

All future cell phones will be compatible with this. We believe the vast majority of Canadians who have cell phones will be able to get these alerts starting Friday.

People who don’t have up-to-date phones will still get alerts on radio and television.

Q: What does it mean when you hear the sound come out of your phone?

A: It means there is imminent danger to life and limb and it’s one of the reasons why we don’t allow people to opt out of this program.

When you hear the tone, it means that there is an emergency that needs immediate action. Typically, that would be something like a tornado or a forest fire [but] it can be used for Amber Alerts as well.

It won’t be used, for example, for heavy snow fall.

If you hear this alert it’s very important to take action immediately. [You should] read the alert and take appropriate action.

Alerts in both official languages

Q: Will it have sound and send out information?

A: That’s right. One of the reasons why this has taken a while to implement is because it’s capable of sending alerts in both official languages.

It will have that sound, which is the same sound you hear on television or radio, and then you will see the message.

Q: Will there be geographic limits on who hears what sound?

A: There will actually be … One of the benefits of using cell phones with LTE technology is they are geolocated … It sends you the alert for where your phone is at the moment.

So for example, we’re here in Ottawa [but] if you were to travel to Vancouver with your phone and there was an alert in Vancouver you would get the alert there, but not the alert for Ottawa.

[This] will work anywhere in North America.

Not replacing radio and TV alerts

Q: What if your phone is turned off?

A: If your phone is off you won’t hear the alert … It’s not replacing radio and television alerts.

In some cases of particular emergencies, of course, emergency management organization will also send people door to door.

It’s meant to be part of a system. It is not meant to be the sole way of reaching Canadians with emergency alerting information.

Emergency management organizations … [will] determine which alerts to send and when.

I think they will be managing that very carefully and they are not going to be sending any middle of the night alerts unless they’re pretty sure about it.

Q: Will it cost people money to receive this alert?

A: It does not use either your text messaging system or your data system.

It uses cell broadcast, [which is] a push system. Your wireless company will push it out to you but they have no way of tracking whether you received it or not.
