nanoLOC TRX
High Performance RF Transceiver
Enabling Location Awareness
Highly Integrated Solution with Ranging
Key Features
The nanoLOC TRX Transceiver is a highly integrated mixed
signal chip utilizing Nanotron’s unique wireless communica-
tion technology CSS (Chirp Spread Spectrum).
+
Single chip 2.4 GHz RF Transceiver operating in the
worldwide ISM Band
+
+
Integrated MAC controller with FEC and CRC checking
Automatic retransmission and acknowledgement, as
well as automatic address matching
With its unique ranging capability, nanoLOC can measure
the link distance between two nodes. Thus, nanoLOC sup-
ports location-aware applications including Location Based
Services (LBS), enhanced RFID, as well as asset tracking
(2D/3D RTLS). As ranging is performed during regular data
communication, additional infrastructure, power, and/or
bandwidth is not required.

Low supply voltage.................................2.3 – 2.7 V
Improved Coexistence Performance
nanoLOC supports a freely adjustable center frequency with
3 non-overlapping frequency channels. This provides sup-
port for multiple physically independent networks and im-
proved coexistence performance with existing 2.4 GHz
wireless technologies.

Data rates are selectable from 2 Mbps to 125 kbps. Due to
the chip’s unique chirp pulse, adjustment of the antenna is
not critical. This significantly simplifies the system’s installa-
tion and maintenance (“pick and place”).

External power amplifier supported
A sophisticated MAC controller with CSMA/CA and TDMA
support is included, as is Forward Error Correction (FEC)
and 128 bit hardware encryption. To minimize software and
microcontroller requirements, nanoLOC also provides
scrambling, automatic address matching, and packet
retransmission.

Medical Applications
Superior Ranging with SDS-TWR
Nanotron's SDS-TWR algorithm (Symmetrical Double-
Sided Two-Way Ranging) allows superior accuracy even
with the use of low cost crystals for the oscillators. High
frequency clocks are not required to achieve a resolution
of less than a meter.
Minimal External Components Required
The nanoLOC TRX Transceiver can work with almost ev-
ery microcontroller. It is designed so that only a minimal
number of external components are required to build a ful-
ly operational bi-directional wireless communication node,
thus reducing the BOM to a minimum.
SDS-TWR enables low-cost and easy to install infrastruc-
ture RTLS – freeing you from the burden of expensive
readers and time-synchronization cabling.
Flexible Development Tools
nanoLOC is fully supported with development and evalu-
ation tools as well as drivers and demonstration software.
Designers can quickly evaluate and develop custom loca-
tion-enabled and ranging wireless applications.

mance or Ranging Evaluation Kits, the nanoLOC Devel-
opment Kit, and the nanoLOC nTRX Driver.
