World's First Wireless Ultra-Narrow Band Transceiver for IoT Applications

Leti, a technology research institute at CEA Tech, will demonstrate the world’s first wireless transceiver dedicated to ultra-narrow band (UNB) communications at the International Microwave Symposium (IMS 2017) in Honolulu, Hawaii, June 4-9.

UNB (ultra-narrow band) 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.

The single-chip sub-GHz transceiver developed by Leti is know as Foxy. Foxy 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.

In addition to the UNB device, Leti will present its latest developments in IC design dedicated to 5G communications in five talks during the IMS and RFIC conferences:

Leti will demo the UNB transceiver at IMS booth #1937 from June 6-8, 2017.
