Atmel Corp. launched the AT86RF233 2.4GHz IEEE 802.15.4 radio transceiver that supports distance measurement between two radios, also known as ranging, in wireless sensor network for IEEE 802.15.4 2.4GHz radio signals.

This novel technology uses the measurement of phase differences between radio signals and enables items to be tracked within a wireless network for industrial and consumer applications. Phase measurement is a less complex technology than current distance measurement technologies available on the market today, with similar measurement accuracy and lower overall system cost.

Many of today's applications for wireless networks come with the inherent need to determine the location of the individual nodes within a 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.

"In this era of the Internet of Things, we are seeing an increase of smart, connected devices within the wireless networks," said Oyvind Strom, Sr. Director of Wireless Solutions, Atmel Corp.. "With this increase, many of our customers are demanding solutions that efficiently support the installation and maintenance of their systems. This new phase-difference technology can be used to determine the position of nodes within a network to help address these demanding requirements. By using a cost efficient standard radio transceiver, Atmel significantly helps lower the overall bill of materials for such systems."

To accelerate a designer's project, software evaluation kits utilising the REB233SMA-EK are available now. Atmel AT86RF233 transceivers, introduced in April 2012, are available in mass production.
