Atmel Has Demonstrated at Embedded World in Nuremberg This Week Its Radio Transceiver

Atmel has demonstrated at Embedded World in Nuremberg this week its AT86RF233 2.4GHz IEEE 802.15.4 radio transceiver carrying out distance measurement between two radios. A process known as ranging.
 
It can be necessary to determine the location of the individual nodes within a wireless network to keep installation and maintenance costs low. 
 
The capability to determine the distance between any two nodes within a wireless sensor network is the reason for implementing positioning and localisation solutions. While GPS is very successful outdoor, it cannot support indoor applications efficiently.
 
Phase difference
 
However, Atmel said that the measurement of phase differences between radio signals is a less complex technology.
 
"This new phase-difference technology can be used to determine the position of nodes within a network," said Oyvind Strom, senior director of wireless solutions at Atmel.
