LIRNEasia@10 - LIRNEasia is celebrating its 10 year anniversary. Check out our timeline of events

A response to an essay about mobile access not being real access to the Internet

This is not to dismiss the idea of connecting via mobile phones. I have spent the last few years researching the challenges of pulling together real connectivity and access for the poorest, and it’s no picnic. Infrastructure constraints, high taxes on imported computers, low income levels and connectivity problems all make the internet extremely challenging […]

Cloud computing is needed in developing countries, but the barriers have to be understood

Today at IGF 2013 in Bali, I was part of a panel on cloud and mobile computing. We at LIRNEasia need cloud computing. But we are also realistic about the challenges. Here is the slideset I used to illustrate the quality problems. But I also talked about the weak links in the chain and what […]

Fraudband in Germany too?

Germans have a reputation for technical prowess. You’d expect the operators there to be technically superior in delivering what they promised when they sold broadband service. But it appears that they have not been so, according to a New York Times report. A government study released Thursday supports what many German consumers have long suspected: […]

Mixed messages from Bangladesh regulator

For too long the government of Bangladesh has hesitated to accept the fact that the only realistic way a majority of its people can be connected to the Internet is over wireless media and has tended to treat the mobile industry as a cash cow to be taxed in order to fund Digital Bangladesh and […]

Slow WiFi can ruin your broadband experience

I like to point out in all the talks that I give on broadband that it’s the slowest link that defines the experience, as in the strength of the weakest link is the strength of the chain. Here is an excellent illustration that uses an example that is close to home (or in the home […]

Quality of service and sending-party-network-pays: An absurd connection

Mr Luigi Gambardella of ETNO responded to one of my tweets and asked me to relook at their proposal. I did (CWG-WCIT12/C-109 of 6 June 2012). On the face, it appears that they are concerned about broadband quality of service, a real problem that we have been working on since 2007. But then they go […]

Diagnosing broadband quality in the Pacific

The Pacific is a tough environment for ICTs. Small populations scattered across thousands of islands over one third of the earth’s surface. More or less the opposite of South Asia. But distance does not make the need for broadband less. One requires more access when one is far away. Since 2006, when I first came […]

Belated post on presentations made at ITS India conference, New Delhi, Feb 2012

LIRNEasia organized a panel on Broadband Bottlenecks in Asia at the ITS India Conference. Here are the slides that were presented at the session, with apologies for the late posting. Helani Galpaya presentation on “Network bottlenecks in South Asian broadband?” Rohan Samarajiva and Abu Saeed Khan presentation on “Removing a broadband bottleneck: International connectivity” Payal […]

Throttling more common in mobile networks than on fixed networks?

As attention shifts to broadband quality of service experience, more tool for understanding what’s going on are becoming available. One tool Glasnost is described in the NYT: In general, the Glasnost results suggest that telecom and cable TV operators, when they do use throttling, do so mostly to suppress bandwidth hogs and ensure a reasonable […]

Extending the reach of LIRNEasia research: Broadband QoSE results in a popular blog

A good value-added blogpost drawing from LIRNEasia research Helani Galpaya’s work: These are only a few graphs and download speeds are only one measure. What’s nice is that we can now quite confidently say Sri Lanka’s Internet and not be talking about a niche product. There are at least 280,000 fixed subscribers (including dial-up, ADSL […]

Data Centers expand, including in China (surprisingly)

Our work on broadband QoSE showed that quality deteriorates when one has to communicate with the Internet cloud. We’ve been pushing for action to reduce the prices of international backhaul from Asia, which 3-6 times the prices in Europe and N America. Another solution is to bring the data centers closer. Appears that is happening, […]

Bhutan acts swiftly on AT Tester findings

On May 9th and 10th, LIRNEasia presented a selection of its research on Bhutan and of potential relevance to Bhutan at events organized in Thimphu. The following news report indicates that BICMA the Bhutan regulatory body is acting on one of the findings of the diagnostic tests run on broadband connectivity in Bhutan that showed […]

New tool for measuring broadband quality

When we started on measuring broadband quality back in 2007 along with our colleagues from IIT Madras, there was little else beside speedtest. Then the FCC got on the bandwagon. Now another tool. Everyone talks about being more customer-centric these days. And the incentive for focusing on customers is growing in part because customers are […]

Crowdsourced broadband QoS, with value added

We thought up the idea of crowdsourcing broadband QoSE, but could not make it work because the AT Tester was too complicated. In the US, they came with the idea two years later but made it work. Now someone has added value to that product. Given many governments in the region (e.g., Bangladesh, India and […]

Sri Lanka: Regulator promises higher download speeds

For a long time, we were the voice in the wilderness. But now the regulator is on the job. If the promised results materialize, we can move on to something else: “Three months ago, most operators were provided services 70% less than the speed rate advertised in the package”, TRC Director General Anusha Palpita said. […]
