NUREMBERG, Germany, Feb. 26, 2013 /PRNewswire/ -- Embedded World 2013 -
Atmel^® Corporation (NASDAQ: ATML), a leader in microcontroller (MCU) and
touch technology solutions, today announced its recently launched AT86RF233
2.4GHz IEEE 802.15.4 radio transceiver supports distance measurement between
two radios, also known as ranging.


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 localization solutions. While GPS is very
successful outdoor, it cannot support indoor applications efficiently.

"We have been evaluating several different technologies including RSSI, Chirp
and UWB methods for radio-based distance measurements over the last years,"
said Andreas Werner, Managing Director of Agilion GmbH. "We've seen all these
technologies only suitable for niche applications, either compromising
performance or significantly complex which ultimately drive the cost-per-node
much higher. The new Atmel technology establishes a unique value proposition
by combining wireless sensor networks with real-time location (RTLS)
capabilities even for mass market applications."

"Precise animal tracking is important in our business," said Eyal Brayer,
Founder of SCR. "We selected the Atmel AT86RF233 transceiver for our SCR
systems because of the new phase-difference technology. This technology allows
us to precisely track hundreds of cattle in our large dairy farms within a
single wireless network, enabling our customers to bring products faster to

"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 Corporation. "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."

Evaluation Kits
