Wireless UNB Transceiver Foresees Apps For ‘Massive INTERNET OF THINGS’

Leti, a technology research institute of CEA Tech, will demonstrate the world’s first wireless transceiver dedicated to ultra-narrow band (UNB) communication at the joint conferences of IEEE Radio Frequency Integrated Circuits (RFIC 2017) and the International Microwave Symposium (IMS 2017) in Honolulu, Hawaii, June 4-9.

 

UNB is an enabling technology for low-cost and low-power wide-area (LPWA) networks. It is one of the core technologies employed by IoT network providers such as Sigfox and Telensa. Based on spectrally efficient modulations such as differential binary phase-shift keying (DBPSK) and Gaussian frequency-shift keying (GFSK), UNB simultaneously optimizes network capacity and maximizes the communication link budget.

 

Known as Foxy, the single-chip sub-GHz transceiver developed by Leti is a 65nm CMOS device that pushes UNB technology beyond state of the art. It can achieve unprecedented bandwidths of 100 Hz, even while doubling the power efficiency of the downlink.
