Atmel has developed technology allowing its recently launched AT86RF233 2,4 GHz IEEE 802.15.4 radio transceiver to support distance measurement between two radios, also known as ranging.
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.
Atmel’s 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. According to the company, this is less complex than current distance measurement technologies available on the market, with similar measurement accuracy and lower overall system cost.
To accelerate a designer’s project, software evaluation kits are available.
