At the Consumer Electronics Show (CES 2016) in January 2016, the Wi-Fi Alliance introduced the HaLow designation for the new low power, long range Wi-Fi protocol IEEE802.11ah, developed by the IEEE standardization committee. This new protocol is especially optimized for Internet of Things (IoT) applications.
Imec and Holst Centre’s fully digital polar transmitter meets the tight spectral mask and error-vector-magnitude (EVM) requirements of conventional Wi-Fi standards. The power consumption of the transmitter is as low as 7.1mW, when delivering 0dBm output power and operating from a 1V supply. This represents a 10x power reduction compared to state-of-the-art OFDM transceivers.
Imec’s Intuitive internet-of-things R&D program aims at developing the building blocks for the future internet of things, an intuitive IoT, with sensor systems that are aware of us, our perspective and our environment and react exactly as we need or want, assisting us in an unobtrusive way. Imec’s research activities focus on the development of ultra-small, low-cost, intelligent, and ultra–low power sensors, radio chips and heterogeneous sensor networks.
