Low Cost Low Power DedicatedTransceiver For Sigfox WorldwideNetwork!
What is Foxy?
Foxy is a single-chip Sub-GHz transceiver that connects Things to the Sigfox network, anywhere in the world, enabling:
Event-based IoT applications thanks to its:
- Marginal cost, miniature solution
- MPU-free autonomous mode
- Embedded Sigfox-compliant frame encoder
- 5 to 10 years foreseen lifetime on a coin battery
Complex IoT use cases thanks to its:
- SPI interface
- Datarates from 0.1 to 20 kbps DBPSK/GFSK
- Bidirectional modulator
- 1-Hz resolution frequency synthesis
Specifically designed for the Internet of Things, Foxy enables both marginal cost, event-based, massive IoT applications and complex IoT scenarios which require aggressive node lifetimes.
Foxy can build tomorrow’s millions-of-Things applications including predictive maintenance and asset management.
Ultra-narrow-band (UNB) is an enabling technology for the Internet-of-Things. UNB simultaneously optimizes network capacity while maximizing the communication link budget of Low-Power Wide-Area (LPWA) networks.
Foxy is the first wireless transceiver dedicated to UNB. Foxy is a low power, low cost 65nm CMOS transceiver that allows GFSK and DBPSK modulations as well as data rates from 100bps to 20kbps. Foxy covers the complete Sigfox specifications including ETSI, FCC, ARIB and AUS/NZ bands and its TCXO-less protocol.
Going beyond Sigfox specifications, Foxy can push the UNB paradigm to its limits. Indeed, at ultimate narrow bandwidths, this technology is historically limited by Carrier Frequency Offsets (CFO) and drift, classically mitigated using
a precise but costly TCXO.
Thanks to Foxy’s unique capabilities, unprecedented bandwidths of 100 Hz can be achieved even in the downlink, without a TCXO.
