While driving down from Moolchand to New Delhi Railway station, the clock on the big hoarding (next to CGO complex said) - 4:32am. Actually the time was close to 6:15am. How do get up there and fix the clock. Time is not far when the clock would be enabled with a GSM SIM inside it and can be remotely controlled from a control panel -either on another mobile or on a computer terminal. The control panel could also get a report indicating that the clock was either behind or running fast -- so corrective action could be taken.
Wireless sensors can do a lot more than get the correct time on the clock. They could transmit information on weather, temperature, brightness, traffic, diesel level on a telecom tower in a remote area etc. They could also be integrated on the top of network routers and transmit alerts on an alternate channel when the Internet traffic which they monitor reached un reasonable thresholds.
Time is not far when such sensors would make devices more intelligent and also controllable.
