F4: Wireless low-power transceivers for local and wide-area networks.

An overview and comparison is provided of the different emerging wireless standards and their circuit solutions, which target low data-rate IoT applications, featuring ultra-low-power and/or long-range. Different RF transceiver implementations are presented, including proprietary solutions in license-free spectrum, WLAN-based IEEE802.11ah solutions and mobile operatorsu0027 alternatives based on emerging long-term evolution (LTEM) standards. The different approaches coming to the market and their circuit design aspects will be discussed.
