nanoLOC TRX
High Performance RF Transceiver
Enabling Location Awareness
Highly Integrated Solution with Ranging
The nanoLOC TRX Transceiver is a highly integrated mixed
signal chip utilizing Nanotron’s unique wireless communica-
tion technology CSS (Chirp Spread Spectrum).
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.
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”).
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.
