Mobile Phone Technology and Developing Nations 54

Posted by samzenpus from the can-you-help-me-now dept.
angry tapir writes "Mobile Operator Tata Teleservices is testing technology that allows farmers to use their mobile phones to remotely monitor and switch on irrigation pump sets in far-flung locations. The technology, called Nano Ganesh, is being tested in two villages in the Indian state of Gujarat. In India, where the electricity supply is erratic, farmers often walk several kilometers to where their irrigation pumps are located, only to find that there is no electricity available. By dialing a code number from a mobile phone to a wireless device attached to the pump, farmers can now remotely monitor the electricity supply, and also switch the pump on and off. It's just the latest example of how mobile phone technology is being employed in novel ways to solve problems in developing nations. For example in Kenya, GSM technology has been used to help tame marauding elephants."

    In most of the Developing economies mobile phones are the first and mostly the only computing devices people have. How much can they realize the potential of such devices is upto the developers and innovators. Having a computing device gives people a lot of leverage. The challenge to us as developers is, can we use it solve real world problems ? Can we make people's lives better with technology ? Or do we continue to waste time in iFarting and Pulling the Fingers ? Or in having a flame-war about OSes and Vi over Emacs ?

    Kudos to Tata Teleservices.

      Can we make people's lives better with technology ?

      By "people", you must mean the execs and stockholders of Apple and AT&T. We (the USA) have not yet reached the status of 'developing nation'. We're still under the thumb of corrupt officials who bend the laws around to maximize their take from the economy. The only difference is that, in Africa, its someone who has installed himself as president for life. In this country, its private business getting legislation (like DMCA) written to keep technologies safely locked inside their walled gardens.

    My company currently produces what we call "potato stations" though they can be used in farming of other stuff.
    They monitor humidity of soil and some other factors like temperature, and send SMS when these exceed preset thresholds and require attention.
    The SMS can be either received on personal phone so the farmer just goes to start the sprinklers or whatever, or can be read by automated system that does it without human attention.

      It isn't as bad as you think with this kind of devices. Due to lacking size restrictions like normal cellphones, they can afford decently-sized antennas in place of the puny things put in the phones, and since you don't keep them to your head, they can emit stronger signal too.. That means the coverage is vastly better than in case of normal phones.

      The downside is the battery life - the battery should optimally last at least one farming season. Thus it is much better if the devices don't listen in to outside communications, but simply report their status periodically, waking up for a minute once a hour or so, collect overdue SMS config/request messages, collect data, then send out what is to be sent (if any). No interactive communication.

        With low-powered handsets, it's not economically feasible to cover sparsely populated areas. With high powered devices and well-placed antennas, a large area can be covered with less infrastructure than a network that otherwise serves typical handsets.

        Plus, regular GSM is limited in distance - it won't work more than 20 miles away from the base station. CDMA and WCDMA do not have this limitation.

    • Whilst this is true, its also alot smaller problem than trying to lay cables to every individual house/street/village etc, for a wired service.

      No problem with the coverage here in the Philippines. Up to just recently, my research is on remote control of scientific and biomedical devices over IP networks including GSM, 2.5G and 3G networks. We were able to do telemicroscopy using a phone. We're now in the second year of a grant to design and deploy telehealth devices to underserved areas. If everything works as expected, it would surely help a lot of people and personally give me a lot of satisfaction.

        True, asterisk is powerful and convenient, but you need a whole computer to run it, and a computer in that area is a real magnet for thieves, unless you put it in a wall and cover it with bricks and mortar.

        A phone, on the other hand, can be powered by a solar cell and a charger, and takes time to find, especially if hidden well in a big place.

    Since the switch would need a battery and charger of some sort to operate it and the radio link, just get a pump that runs on solar.
    They make anything from .25GPM up to like 50,000GPD.

    I was in Cambodia last week, when I saw a weather alert sent to locals via a free SMS. It was warning people that a storm was spotted with dangerous lightning, so people should go indoors.

    In a place without the weather channel, I thought this was a rather inspired way to easily inform people of approaching danger.

      • I actually don't see many radios there, and it seems like almost everyone has a cell phone. Since most can double as a music player, people gravitate to that instead. Also, the preferred transportation is motorbike, which doesn't have one at all.
