Remote Data Exchange – SMS and GPS based products

Remote Data Exchange (RDX) is an interesting Pune-based company that builds a number of products based either on GPS devices, or based on idea of using SMS for achieving things remotely. They have recently released a product called Jai Kisan which is essentially a setup that allows farmers to remotely manage their motor pump sets.

This system has the following features:

  • Allows you to start or stop the motor pump set from anywhere
  • Works with any kind of GSM/CDMA Mobile handset
  • Gives you feedback about whether the motor actually started or not
  • Tells you if power is present on the field or not
  • Automatic charging of mobile handset
  • Ultra low cost, INR 1250/- only

This is just one of the products they have up their sleeve. There are a number of other little products based on these technologies. For example, there is the sms-based car security system which:

  • Allows you to figure out the the location of your car from your mobile at any time by giving your car a missed call
  • Turn ON or OFF Car Engine from your Mobile. (I wonder whether I can use it to remotely turn on the AC!)
  • Car immobilization via SMS message
  • Intrusion SMS message alert – if the door is opened in your absense.
  • ARM/DISARM the security system via SMS message
  • Lowest recurring cost per month: based mainly on simple sms messages (and in some cases missed calls!)

There is a similar sms-based system for home security too. And a Bike security system (which doesn’t appear to be sms-based.) And a vehicle tracking system (which is integrated with Google/Yahoo/MSN/NASA maps. Useful for car fleets (think BPO pick-up / drop-off.)

Then they get into “Big Brother” management techniques. The person tracking system which is a small GPS device that can be given to an employee, and will then send detailed reports about the whereabouts of the employee to the supervisor. A similar thing can also be achieved by simply giving the employee a GSM mobile phone. Apparently to be given to employees who have a tendency to lie about whether they actually visited a customer or not.

See the full punetech profile for more such mini-products from RDX. Like the sms-updatable LED displays. And GPS based clocks (always exact time.) And GPS based Passenger Information System. This is installed, for example, in some AC coaches in Indian Railways and gives the passengers video clips with local information (i.e. about the station they are going to soon reach) based on where the train currently is.
