The Third Wireless Evolution – Sensor Networks?
If you ever had the foresight in 1970 to wonder along what sequence of events wireless technologies would start penetrating society, you probably would not have started first with high quality voice networks, then followed with high speed data-networks and finally ended with low data rate, low duty cycle simple sense and control networks. Most likely you would have suggested a sequence the other way around: let’s start “slow and easy” with sense and control networks (sending temperature information every 5 minutes and control our heaters or air conditioners); then you may have guessed that this would have been followed by more complex data networks, as a higher speed next generation data network, and finally the wireless revolution would have been completed with the most complex voice networks with its high demands on low latency and high quality.
