Inpixon Swarm Chirp

Compact, Low-Power, Chirp Radio and Sensor Module

Product photography for the Inpixon Swarm Chirp RTLS sensor module, formerly known as the nanotron swarm bee LE

The Inpixon Swarm Chirp (formerly swarm bee LE) is a 2.4 GHz Chirp Spread Spectrum (CSS) module suitable for a multitude of IoT implementations. Its small form factor, low power consumption and long-range transceiver makes it ideal for wearable IoT devices and discreet product designs and can be used for personnel, equipment, and asset tracking products where indoor and outdoor location sensing is critical.

This miniaturized radio transceiver features embedded accelerometer and temperature sensors and has a configurable transmission power output to further stabilize communication reliability and connection robustness. Far exceeding typical radio and sensor module application ranges, the Inpixon Swarm Chirp is capable of a radio range up to 1,000 meters.
