It has allowed Developing World countries to establish telecommunications networks at a fraction of  the cost of putting in an expensive landline infrastructure that would include hundreds of kilometers of poles and wire. But even mobile telephone networks can be interrupted in a crisis. That’s why TRiaGnoSys, a mobile communications company headquartered in Germany is designing a mobile telephone network that can be deployed in minutes using kite-shaped helium-filled balloons called Helikites. One can be seen in the picture appearing at the bottom of this posting.

Helikites are helium-filled balloons with kite-like features. They have been used as airborne platforms for cameras and remote sensing. But TRiaGnoSys is using these balloons to lift as much as 10 kilograms (22 pounds) of its LAP (Low Altitude Platform) telecommunications technology to altitudes as high as 4 kilometers (approximately 2.5 miles) providing local mobile signal coverage for voice and data. Using DACA, Deployable Aerial Communication Architecture, each payload creates an instant local mobile network that can then be linked to ground-based communications or telecommunication satellites.  Each Helikite when deployed is tethered using multiple lines to ensure minimal drift and no loss of signal. It is easy to deploy multiple Helikites over an area as needed.

So where and when would you deploy a Helikite LAP? Primarily say its developers for use in the event of a disaster such as an earthquake or flood when critical land-based infrastructure becomes damaged. A Helikite LAP would not only provide emergency telephone service but the payload could also contain remote sensing equipment and cameras to provide ongoing real time data and pictures. Another application is for use with mass events such as the Olympic Games where mobile phone use could overwhelm the existing cellular infrastructure.

I haven’t been able to find out the cost of deploying such a network but you can read about the technology by going to the paper that describes it and the challenges the developers face.

In Pursuit of a Global Technical Society https://techsomogro.com/pursuit-global-technical-society/?utm_source=rss&utm_medium=rss&utm_campaign=pursuit-global-technical-society https://techsomogro.com/pursuit-global-technical-society/#comments Mon, 24 Dec 2012 16:52:02 +0000 http://www.21stcentech.com/?p=8048 Here we are in the last week of 2012 with another 88 years before we see the end of the current century and I am one of those who is hopeful that we have the tools to make the world by then a much better place for all of humanity and the biodiversity that surrounds us. That’s because we are beginning to witness a planet-wide revolution in the use of technology as the fruits of our know how spread even to the most unlikely places and begin to change lives forever.

Here are just a few examples from some recent press clippings:

  1. Brazil’s rural tribes in Amazonia are taking to DVD players and mobile phones in a big way. In a survey of 32 indigenous villages in the Amazon basin, 37% of households reported owning a DVD player while 36% had mobile phones.
  2. In Sub-Saharan Africa  mobile phone use continues to grow at a rate of 40% per year and is expected to achieve 50% market penetration by 2014.
  3. In North Africa mobile phone use penetration rates have exceeded 93%. That goes a long way to explaining the “Arab Spring.”
  4. Of the almost 4 billion people of Asia, more than 1 billion, 27.5% were Internet users as of June 30 and almost 236 million were on Facebook as of September 30.
  5. Even in Oceania, the island nations of the Pacific, 67.6% of the population were Internet users and 14.6 million were on Facebook.
The chart and map above show the increasing use of mobile phone technology and projected growth rate in Sub-Saharan Africa.

Of course there remain pockets where 21st century technology has yet to make a significant impression. In Bangladesh, one of the poorest countries on the planet, Internet usage has only reached 5% of the population of its 160 million citizens. And in places like North Korea the 24 million of its people remain isolated from the global conversation.

Another dark side is the propagation of 21st century technology without safeguards. China is the one country where this phenomenon is quite visible. A good example can be seen in the transportation sector where there is a rising demand for automobiles. The Chinese have caught the North American and European bug about cars. Beijing, Guangzhou and Shanghai are the hottest markets and have had to resort to a lottery to allocate vehicle registrations. To service this demand, the country has added 32,000 kilometers (almost 20,000 miles) of new paved highway in the last 5 years, a rate 4 times faster than the speed with which the United States built out its Interstate highway system. The bicycle, once the principal means of transport for so many in China, has receded as automobiles have taken over.  Where 60% of trips taken in Beijing back in 1986 were by bicycle, today that number is 17% today. The result for China is 300 traffic fatalities per day, the highest rate in the world, and smog in its urban centres caused by automobile tailpipe emissions.

This picture is of a 100 kilometer (62 mile) traffic jam on a highway leading to Beijing that occurred in 2010. It took more than ten days to clear the congestion.

The 21st Century Electricity Capacity Challenge

Today 1.3 billion of us have no energy security and 2.7 billion lack clean cooking facilities. Electricity consumption in Sub-Saharan Africa, excluding the Republic of South Africa, is about equal to that used by the State of New York. That means 20 million New Yorkers consume the same amount of electricity as 850 million Africans. To deal with this challenge the International Energy Agency estimates we need to invest $48 billion U.S. annually to achieve 100% penetration by 2030. Interestingly, money spent by governments on fossil fuel subsidies is nearly ten times this amount.

What would universal access to electricity mean for the world’s population? Less burning of carbon, not more, as poorer countries move away from cooking fires to cleaner energy sources.

What will it take to get to universal accessibility? Global political will that includes building financial capacity in the Developing World to ensure investment are made in energy projects and in urban and rural infrastructure to deliver energy everywhere.

Mobile phone penetration and Internet growth are leading the way and showing us just how hungry the Developing World is for 21st century technology.  If we can duplicate the 21st century revolution happening in communications by making electrical power accessible and ubiquitous we can involve the entire planet in collective progress. Wouldn’t that be a great New Year’s Resolution?
