Alert Delivery-Typical Timeline Actions at the Alerting end Time = 5:35 pm Tsunami warning received from NOAA 5:36 pm (1 minute elapsed) Confirm the message Type out Alert parameters in the CAP format using the WorldSpace GUI Record a short audio message in the local language Convert audio file to the required format and FTP to WorldSpace server 5:40 pm (5 minutes elapsed) Issue the Alert through WorldSpace text channel Insert audio in the alert audio channel At the Receive point Time = 5:41 pm ( 6 minutes elapsed) AREA –C sounds a siren, displays alert parameters and switches the audio to the alert audio messaging channel whether or not the radio was being used at this time AREA-M responds to this alert signal only if its current position is inside the alert zone. It also displays the text and plays out the alert audio channel AREA-A uses the computer to provide a more comprehensive display of the alert parameters, plays the alert audio on the computer and optionally generates a siren sound on the computer.

Actions at the Alerting end

Time = 5:35 pm

Tsunami warning received from NOAA

5:36 pm (1 minute elapsed)

Confirm the message

Type out Alert parameters in the CAP format using the WorldSpace GUI

Record a short audio message in the local language

Convert audio file to the required format and FTP to WorldSpace server

5:40 pm (5 minutes elapsed)

Issue the Alert through WorldSpace text channel

Insert audio in the alert audio channel

At the Receive point

Time = 5:41 pm ( 6 minutes elapsed)

AREA –C sounds a siren, displays alert parameters and switches the audio to the alert audio messaging channel whether or not the radio was being used at this time

AREA-M responds to this alert signal only if its current position is inside the alert zone. It also displays the text and plays out the alert audio channel

AREA-A uses the computer to provide a more comprehensive display of the alert parameters, plays the alert audio on the computer and optionally generates a siren sound on the computer.

The Implementation Challenge New Technology Alert Delivery is the responsibility of a government agency and usually that agency has no role or budget for social development Need for coordination among Ministries A comparatively large one-time investment if it has to scale up to its full potential Need owners for the activities at non-alert times (which is hopefully most of the time!) Continued training of personnel at the hub as well as in the communities Sustainability and upkeep of the system

New Technology

Alert Delivery is the responsibility of a government agency and usually that agency has no role or budget for social development

Need for coordination among Ministries

A comparatively large one-time investment if it has to scale up to its full potential

Need owners for the activities at non-alert times (which is hopefully most of the time!)

Continued training of personnel at the hub as well as in the communities

Sustainability and upkeep of the system

Model in Indonesia-PPP Satellite Capacity Alert Content Commercials

Stakeholders: Indonesia Datacast for Group of Media Companies Re-use Strategy Chosen BMG Hub Operation Private Sector Integrator Training & Upkeep Media companies Custodians for Receivers Advertisers Datacast Content BMG (Government) Alert Content WorldSpace Channel Capacity

Model in Sri Lanka

Stakeholders: Sri Lanka Audio channel 24 x 7 for community use Re-use Strategy Chosen Sarvodaya HIH Operation Sarvodaya Training & Upkeep Sarvodaya Village Units Custodians for Receivers Sarvodaya (NGO) Audio Content DMC (Government) Alert Content WorldSpace Channel Capacity

Model in Bangladesh

Stakeholders: Bangladesh Audio channel 24 x 7 for use in fishing boats (PFZ, Weather etc.) Re-use Strategy Chosen DMB- Trained by Vista and BUET HIH Operation Vista Communications Training & Upkeep Individuals Custodians for Receivers Vista Communications (Private Sector) Audio Content DMB (Government) Alert Content WorldSpace Channel Capacity

In Summary The Government Agency responsible for Alert Delivery needs local partners These partners can be NGO’s, Private sector or other national organizations (Each country has to choose a model that best suits it) Non-alert time usage of the system vital not only for the economics, but for the local acceptance & up keep of the system If implemented in a large scale, across multiple projects and over a long duration, these solutions are cost-effective Need to bring in regional cooperation and inter-operability Important to adopt CAP and establish a Transmission Hub for all hazards, all media and all locations One point generation of the alert and multi point multiple media dissemination is reliable, scalable, sustainable and cost effective.

The Government Agency responsible for Alert Delivery needs local partners

These partners can be NGO’s, Private sector or other national organizations (Each country has to choose a model that best suits it)

Non-alert time usage of the system vital not only for the economics, but for the local acceptance & up keep of the system

If implemented in a large scale, across multiple projects and over a long duration, these solutions are cost-effective

Need to bring in regional cooperation and inter-operability

Important to adopt CAP and establish a Transmission Hub for all hazards, all media and all locations

One point generation of the alert and multi point multiple media dissemination is reliable, scalable, sustainable and cost effective.
