Abstract IEEE 802.11 ah, marketed as Wi-Fi HaLow, is a new sub-1GHz Wi-Fi technology for
the Internet of Things (IoT), aiming to address the major challenge of the IoT: providing …

Hyperconnectivity, real-time processing, and interoperable communication facilities are key
to the Next Generation (NG) Internet of Things (IoT). However, existing IoT architectures …

IEEE 802.11 ah, marketed as Wi-Fi HaLow, extends Wi-Fi to the sub-1 GHz spectrum.
Through a number of physical layer (PHY) and media access control (MAC) optimizations, it …

This paper presents a 2 GHz digital-to-time converter (DTC) with 244 fs time resolution. The
DTC consists of a multi-modulus divider (MMD) and a phase interpolator (PI) as coarse and …

A fully integrated 750~ 960 MHz wireless transceiver (TRX) is presented for single-tone NB-
IoT applications. Effective design methodologies and techniques, from the system level to …

This paper introduces an ultra-low power 1.7-2.7-GHz fractional-N sub-sampling digital PLL
(SS-DPLL) for Internet-of-Things (IoT) applications targeting compliance with Bluetooth Low …

This paper presents a dual-band high-power digital polar Doherty power amplifier (PA). A
current-mode parallel-combining transformer (PCT) power combiner is introduced for …

IEEE 802.11 ah is the new sub-1 GHz Wi-Fi standard, targeting large-scale and dense
deployments of low-power stations. One of its major improvements compared to previous …

This work presents a wideband digital polar transmitter (DPTX) with an integrated capacitor-
digital-to-analog converter (C-DAC)-based digital-to-phase converter (DPC). A normalized …

The new medium access method of IEEE 802.11 ah, called restricted access window (RAW),
divides stations into different groups, and only allows stations in the same group to access …
