Tracing the SIMs of the Mumbai raiders

Posted on December 9, 2008  /  1 Comments

Here is an update on the search on how the Mumbai attackers coordinated their murderous activities: The police official, Javed Shamim, said both men were in Calcutta in October when Mr. Rehman used a dead relative’s photo identification to buy the SIM cards. Mr. Rehman then activated them and either gave or sold them to Mr. Ahmed, Mr.

Use of mobiles in the Mumbai attacks

It is always informative to engage in a retrospective assessment of the use of technology in a terrorist atrocity and see what we can do to make their activities more difficult (and prevent knee jerk reactions that only make the lives of law-abiding people more difficult). The first reports on the use of mobiles by suicide attackers of Mumbai are coming out: Mr. Muzammil, who is the right-hand man to Zaki-ur-Rehman Lakvhi, the operational commander of the group, talked by satellite phone to the attackers from Pakistan when the gunmen were in the Taj and Oberoi hotels, the Western official said. The attackers also used the cellphones of people they killed to call back to Mr. Muzammil somewhere in Pakistan, the official said.
The Economist, which has been quite skeptical about mobile advertising, has a story which reports takeoff has occurred. What I find interesting is the analysis of which roadblocks have been removed. Here, the relevance of the broadband quality of service experience work we have been doing is noteworthy. Assuming that mobile operators want ad revenues (not a hard assumption), this shows that it is in their interest to improve the quality of service experience from the dismal levels that exist today. Faster networks and lower rates also help.
The New York Times carries a story on the wrong conclusions people jump to when they try to self-diagnose on the web. The story does not say that the findings of the study identify a market opportunity for telecenters, but I do. Apparently two percent of all web searches are health related. Given the massive number of searches devoted to Brittany Spears, Paris Hilton and other luminaries, this is a very significant number. Of the people who search the web for health matters, many want to know about symptoms they are experiencing.

Passage to India

In 1997, NTT bought 35 per cent of a badly managed government phone company called SLT along with the right to manage it for five years for USD 225 million. The decision was bracketed by the Central Bank attack (on a per capita basis more devastating than the World Trade Center hit of 11 September 2001) and the bombing of an empty [Sri Lankan] World Trade Center. Many wondered what the logic was. One explanation was that NTT saw Sri Lanka as a stepping stone to India. But no step was taken.

An antidote to the scare stories

The Internet is a public space, and like any public space it is not without danger. But the scare stories are overhyped as the NYT story based on a USD 50 million research project shows: Good news for worried parents: All those hours their teenagers spend socializing on the Internet are not a bad thing, according to a new study by the MacArthur Foundation. “It may look as though kids are wasting a lot of time hanging out with new media, whether it’s on MySpace or sending instant messages,” said Mizuko Ito, lead researcher on the study, “Living and Learning With New Media.” “But their participation is giving them the technological skills and literacy they need to succeed in the contemporary world. They’re learning how to get along with others, how to manage a public identity, how to create a home page.
We’ve covered the progress of the OLPC from time to time. The person leading the effort in China and South East Asia is an old and good friend, Tony Wong. By now, Mr. Negroponte insists, enough of these learning machines are in the hands of children in the developing world to see results. The children, from 6 to 12 years old, are more passionate about learning and educators are reporting fewer problems with discipline and truancy.
The download speeds that customers get in Chennai, Colombo and Dhaka are not very different, if you carefully examine the results of the October 2009 results of broadband QOSe using the Ashokatissa methodology jointly developed by IIT Madras and LIRNEasia. What differs is the level of truth in advertising. In Sri Lanka, everybody is lying. In India, they are closer to the truth. The difference is regulation.
One of the main reasons for collecting and disseminating indicators data at the regional level is currency. By the time the ITU puts out its reports, two years have gone by, and the data are of historical value in these fast-changing times. Despite knowing all this, even we got tripped up this time. In attempting to release mobile and broadband benchmarks at the same time, we delayed the release of the mobile data collected and analyzed in early October and were overtaken by events. In the future, the data will be released without delay.
Buddhists are duty bound to offers alms. Zarganar, one of Burma’s most popular comedians, did. But to the wrong monks, according to the Generals. They were protesting the government’s misrule. Among other things Zarganar will be charged with offenses under the Electronic Transactions Law.

WiFi on steroids

Chanuka posted the story before the Economist, but it may still be worthwhile reading what the take is from the headquarters of free market thinking: White space could be even bigger. The frequencies involved were chosen for television back in the 1950s for good reason: they travel long distances, are hardly affected by the weather, carry lots of data, and penetrate deep into the nooks and crannies of buildings. No surprise proponents have dubbed them “WiFi on steroids”. Once the changeover from analog to digital broadcasting is complete, the television networks will no longer need the white spaces between analog channels to prevent interference from noise and other transmissions. Apart from digital broadcasts being far less vulnerable to interference, there’s now plenty of frequency-hopping technology around for detecting digital broadcasts and avoiding them.
Few weeks ago I wrote a column about a surreptitious attempt to impose a draconian regulatory regime on TV, cable, satellite and mobile broadcasting. A post in this blog discussed the implications for convergence. There was also a high-profile Sinhala language op-ed that contributed to framing the ensuing debate in relation to a 1997 Supreme Court decision and the recent cancellation of a radio license (rescinded when the owners joined the government party). Now the Supreme Court has stayed the regulation. A victory, I guess.
One of the key actions required to make Mobile 2.0 real is to allow people to use voice commands instead of typed commands. Looks like Google has made a big leap: Both Yahoo and Microsoft already offer voice services for cellphones. The Microsoft Tellme service returns information in specific categories like directions, maps and movies. Yahoo’s oneSearch with Voice is more flexible but does not appear to be as accurate as Google’s offering.
A study by Professor Rajat Kathuria, ICRIER and International Management Institute New Delhi, is now available. In the paper, Professor Kathuria seeks to assess the impact of decline of leased line prices in Indonesia. It tries to capture this impact through qualitative as well as quantitative impacts. Since the decline in prices occurred recently (2008 April), the period post the decline is not large enough to do a meaningful time series analysis. However, qualitative assessment is made and the impact is compared with India, where decline in leased line prices led to substantial benefits to user industries.
The 2009 Budget contains the following statement: Allocations were made in the 2006 Budget to connect rural villages in backward areas with the rest of the world and enable them to blend with the global community and economic trends, through Information Technology. This program has enabled online connectivity through around 500 Nana Sala Centres, between villages, schools and state and public institutions, and also facilitates to broaden the knowledge of English and Information Technology. I propose to name the year 2009 as an year dedicated to expand the knowledge of English and Information Technology and allocate Rs. 100 million to broaden the scope of this programme. The questions are: * The Budget contains no other allocations for ICT related activities, explained possibly by the existence of a USD 80 million or so e Sri Lanka program, funded primarily by a concessionary IDA credit and a Korean loan which has not been fully disbursed and is in danger of being cancelled.

Policy enlightenment

Posted on November 11, 2008  /  0 Comments

Carol Weiss says one of the most useful things researchers can do is to give policy makers the tools to think about problems. She calls this policy enlightenment, as opposed to direct policy influence. In Sri Lanka we now make policy in the Supreme Court. This is not optimal, but it’s the way it is. Therefore, I was pleased to see that Justice Tilakawardene had used one of the analogies I had pushed hard in relation to the recent punitive measures taken against mobile phones.
