Some governments shut down telecom networks including the Internet to control dissent. Others do not. What are the conditions that give rise to the former action? Why do others not do this? Israel never shuts down telecom networks but Sri Lanka does.
There are many who think telecom networks should be congestion free, always, like during or just before a disaster. It is practically impossible because no network can be economically designed and run for unusual peak loads. The report that mobile companies in the US are asking their customers to go easy on calls and MMS, is illustrative of the phenomenon. Why would they walk away from an opportunity to make money? The largest cellphone carriers, fearful that a communicative citizenry will overwhelm their networks, have taken the unusual step of asking people to limit their phone calls and to delay sending photos.
Serving Sri Lanka: Indian Ocean tsunami warning capabilities improving Addressable satellite radio sets were found to be the best alerting technology of the community disaster warning pilot project conducted by LIRNEasia and Sarvodaya. Java enabled mobile phones which has a wake up siren came next. The GSM based remote alarm device developed locally by Dialog Telekom, MicroImage and University of Moratuwa followed closely. It has both light and siren.Findings of this project on learning how information-communication technologies and community based training can help in tsunami and other disaster situations had been discussed by community leaders and international experts at a workshop on “Sharing Knowledge on Disaster Warning with a Focus on Community-Based Last-Mile Warning Systems” at the Sarvodaya Headquarters in Moratuwa recently.
By Rohan Samarajiva The findings of a pilot project on learning how information-communication technologies and community-based training can help in responding to disasters such as tsunamis were discussed by community leaders and international experts at a workshop on “SHARING KNOWLEDGE ON DISASTER WARNING, WITH A FOCUS ON COMMUNITY-BASED LAST–MILE WARNING SYSTEMS” held on March 28th and 29th, 2007 at the Sarvodaya headquarters in Moratuwa. These finding ranged from the difficulties experienced in communicating disaster warnings to villages when mobile GSM and fixed CDMA telecom networks were not functional due to conflict conditions to the importance of not leaving newspapers on top of sensitive electronic equipment which can overheat and shut down as a result. In terms of the five communication technologies that were evaluated across multiple criteria, the addressable satellite radio sets and the java-enabled mobile phones performed the best, with the GSM-based community warning device developed locally by Dialog Telekom, MicroImage and University of Moratuwa following closely. The VSAT based warning system did not perform too well in the tests. The objective was not to declare a winner among the technologies, but to find out how they could be improved to perform reliably in the difficult conditions of Sri […]
Our colleagues from Latin America have drawn our attention to the following article, perhaps because they think that our TRE (telecom regulatory environment) work is premised on FDI being an unmitigated good. We welcome the opportunity for a debate. Kevin P. Gallagher and Lyuba Zarsky, “Rethinking Foreign Investment for Development”, Post-Autistic Economics Review, issue 37 Abstract “In the 1990s, foreign direct investment (FDI) came to be seen as a “miracle drug”—a jumpstart to economic growth and sustainable industrial development, especially in developing countries. Policies to attract FDI became the centerpiece of both national development strategies and supra-national investment agreements.
Ten preliminary lessons of the 28th March 2005 Sumatra great earthquake (Photo Source) LIRNEasia, together with Vanguard Foundation, intends to systematically analyze the Sri Lankan media response to the great earthquake of the 28th of March. However, it appears useful to draw some preliminary lessons from this tragedy which has cost over 1,000 lives, including the people of Nias and other islands and those in Sri Lanka and elsewhere who died as a result of the warnings. The conclusions are preliminary; comments are welcome. # Earthquake hazard detection is easy; tsunami hazard detection is not. One cannot simply infer the existence of a destructive tsunami from an earthquake.
