Frequently Asked Questions
What RF frequency and protocol does the ETRX357HR-LRS support for mesh networking?
The ETRX357HR-LRS operates at 2.4 GHz using the IEEE 802.15.4 standard and supports ZigBee PRO mesh networking protocol. It provides AT-command firmware control over a UART interface, allowing host systems to manage network joining, data transmission, and topology without implementing the ZigBee stack directly on the host processor.
How does the U.FL connector on the ETRX357HR-LRS improve deployment range compared to modules with integrated antennas?
The U.FL connector allows connection of external high-gain antennas, such as dipole or directional antennas with 3 dBi to 8 dBi gain, significantly extending usable range beyond the typical 30 m to 100 m of modules with on-board chip antennas. This makes the ETRX357HR-LRS suitable for industrial facilities, warehouses, and outdoor deployments requiring several hundred meters of ZigBee link distance.
Which industrial and smart building applications benefit most from the ETRX357HR-LRS long-range ZigBee module?
Applications such as industrial plant sensor networks spanning large factory floors, smart metering across multi-building campuses, HVAC monitoring in multi-story buildings, and outdoor environmental sensing grids benefit most from the ETRX357HR-LRS. Its long-range RF capability at 2.4 GHz ensures mesh node connectivity even in environments with obstructions, metal structures, and high RF attenuation common in industrial settings.
