From Satellites to Streets

11 Jul

There has been a tremendous growth in satellite-guided navigation systems and secondary applications relying on GIS systems, like finding shops near the place you are, etc. However, it remains opaque to me why we are using satellites to beam this information when we can easily embed RFID/or similar chips on road signs for pennies. Road signs need to move from the ‘dumb’ painted visual boards era to electronic tag era, where signs beam out information on a set frequency (or answer when queried) to which a variety of devices may be tuned in.

Indeed it would be wonderful to have “rich” devices, connected to the Internet, where people can leave our comments, just like message boards, or blogs. This will remove the need for expensive satellite signal reception boxes or the cost of maintaining satellites. The concept is not limited to road signs and can include any and everything from shops to homes to chips informing the car where the curbs are so that it stays in the lane.

Possibilities are endless. And we must start now.
