Scientists track glaciers with RF 'pebbles'

June 21, 2004

BBC News reports: 'Wireless pebbles' track glaciers:

Glacial scientists trying to understand more about how the huge bodies of ice behave have made use of innovative wireless "electronic pebbles" to help.

It is the first time wireless sensors have been used in glaciers to collect information and transmit it instantly over the net to computers elsewhere.

Not unlike what we've seen in the past as applications for sensor-connected Active RFID tags broadcasting information about e.g. the temperature or other stats of freight containers, these sensors track parameters about their surroundings and report back through radio signals as well as SMS, according to the BBC report.
