The Need
 THE NEED is for an alerting system which can cover all hazards and
can be delivered by authorized agencies directly and instantaneously
to those who respond to the emergency.

2
Hazard Warning System (HWS)?
 Internet for HWS
 Usable for small to medium networks where telecom infrastructure is well
developed
 Type of connectivity is point-to-point
 Bandwidth at time of greatest need is not guaranteed
 Time to download can vary
 Depends on available telecom infrastructure
 Problems in handling large files
 Problems in handling streaming data
 Initial costs, usage, and connectivity charges increase with network size

VSATs for Hazard Warning?
—
—
—
—
—
—
Two-way and one-way VSATs
Fixed cost per site significantly higher
Infrastructure requirements higher
Installation and maintenance issues
Regulatory clearances required
Non-scalability downward
VSATs good for small Closed User Groups with large data
requirements – not for HWS delivery to a large number of sites

AREA: A WorldSpace Solution
 Addressable Radio for Emergency Alerts (AREA)
—
—
—
XML based protocol adapted to suit WorldSpace digital satellite radio
system
Special receivers to deliver audio/multimedia alerts selectively, securely
and reliably
Independent of any terrestrial communication therefore can be
deployed and sustained even in the most remote locations
www.worldspace.com
19
AREA: A WorldSpace Solution
 The alert service proposed by WorldSpace allows to offer administrations
(local/national/international) an effective tool for immediate reach of the
populations and local authorities and independent from local terrestrial
infrastructure. It can be used in several domains.
www.worldspace.com
20
AREA: A WorldSpace Solution
Audio/data early warning and crisis communication system. Operates as a single point
of entry for national, regional and multi-continental authorities.
 For audio and data, on a per customer basis, a Web site allowing generation and
broadcasting of alerts and geo-reference alerts.
 For audio, the customer will be able to record and deliver instantly audio warnings
throughout continents to designated receivers.
 A Public Key Infrastructure (PKI) to ensure users authentication and encryption of
exchanged messages.
 XML-based Alerts, allowing interoperability, evolution messages and multi-lingual
communication.
The alert system includes in this base configuration - a DAMB-R2 receiver with an L-band antenna
- a power supply (2 AA batteries or 6V AC/DC adapter
or car power adapter).

Common Alert Protocol (CAP)
 International effort initiated in 2001; finalised October 2005
 Worldspace received a grant from CNES (French space agency,
equivalent of ISRO) to develop an Early Warning System in 2004 prior to
the Tsunami. Under this contract, WorldSpace adopted CAP, which allows
interoperability at the data representation level.
 We also developed a full system including a GIS-based portal together
with an alert terminal with a tactile screen.
 Single message format to handle multiple categories of emergencies over
a wide range of network
Major features:
—
—
—
—
—
Incorporation of geo spatial elements
Association of digital images and binary information with alerts
Ensuring message authenticity, integrity and confidentiality
Full compatibility with Emergency Alert System (EAS) of the United States
Can support the needs of multi-lingual and special needs population
www.worldspace.com
23
The Alert Portal
 Developing a Web-based platform allowing the customer (the
administrations) to manage their recipients, to generate alerts (for audio, a
recording function will be offered) and to geo-reference the alerts either a
built-on GIS (Geographic Information System) or by country codes.
 The customer can access the service through the Internet. A portal is
available for him to manage the terminals and the alerts.
 Access to this portal is fully secured.
 Any user worldwide is a click away. The alert is distributed in less than 10
seconds wherever the terminal is located in the coverage area
www.worldspace.com
24
Alert Management
 The customer can create alerts following the CAP standard. The user
can define and activate recipients though standard forms. He can also
create groups of recipients.
 The addressing of terminals can be done several ways
—
—
—
—
—
by listing the groups of recipients
by defining a geographical area (latitude/longitude)
by defining a country code
by a combination of the above criteria
The system supports also exercise or test alerts.

8.
Data is available – need a media to reach out
Early warning is not limited to coastal area only – fishermen or other
elements.
Something which is being used on daily basis. Not used only at the
time of disaster. Interruption gives the disaster warning –
like “Breaking News in TV”.
Language not a barrier. Audio and alarm both can be configured.
Independent of ground infrastructure. Even at the place of disaster
one can still send messages as quick deployment is possible.
Secure means of communication.
No special training /expertise required to operate.
Limitation – RLOS – Radio Line of Site
