Description
* Highly Integrated Solution with Ranging
The nanoLOC TRX Transceiver is a highly integrated mixed signal chip utilizing Nanotron’s unique wireless communication technology CSS (Chirp Spread Spectrum).
With its unique ranging capability, nanoLOC can measure the link distance between two nodes. Thus, nanoLOC supports 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 support for multiple physically independent networks and improved 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 installation 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.
