LA JOLLA, CA(Marketwired - Feb 3, 2016) - Mobile World
Congress - Acorn Technologies, Inc., a semiconductor and
telecom research and development company, today launched the
commercial availability of its new hellaPHY RSTD advanced
signal processing IP core for LTE network based positioning and
E911 indoor location accuracy standards. The hellaPHY™
RSTD IP core is targeted at the LTE baseband chipset market
providers as the FCC mandates new 911 location reporting rules
for wireless carriers.
hellaPHY RSTD, is an advanced signal processing algorithm
that was developed to improve LTE wireless network indoor and
outdoor location accuracy and offers extreme performance in an
efficient low-power DSP implementation. The algorithm has
been demonstrated to outperform advanced super-resolution algorithms at a fraction of the complexity. It
is designed to be a drop-in replacement for existing Reference Signal Time Difference (RSTD)
algorithms in User Equipment (UE) chipsets and can be customized for any unique DSP or interface
requirements. The hellaPHY RSTD IP core is designed to support advanced LTE features contemplated
by operators as well as for LTE Release 14 including PRS muting, CRS plus PRS transmit diversity, and
fractional Ts reporting. The hellaPHY RSTD IP core is scalable and can support CAT-M through CAT-
15.
"Our latest hellaPHY IP core is based upon our ground breaking work in developing channel estimation
algorithms for LTE basebands and complies with the FCC's new rules on E911 indoor location accuracy
and reporting, that will be mandated for wireless carriers in the very near future," said Steve Caliguri,
vice president of Telecommunications for Acorn Technologies. "We expect to be shipping Acorn
hellaPHY RSTD IP cores in certain LTE basebands later this year."
hellaPHY RSTD can also support indoor commercial applications and will help operators develop new
features to enhance their user experience. The potential for new applications that can rely on a very low-
cost and low power positioning using hellaPHY RSTD are enormous. In particular, with the emergence
of IoT, where the cost and power of traditional GNSS based positioning solutions become more
prohibitive, hellaPHY RSTD offers a low cost and accurate off-the-shelf solution.
