Dal Fabbro, Nicolas Raemy CSEM, Neuchâtel, Switzerland The ubiquitous deployment of the Internet-of-Things (IoT) requires integrated, high performance, and low-cost wireless connectivity. Bluetooth Low Energy (BLE) is popular due to low complexity and relaxed carrier-to-interference suppression (C/I) [1,2]. With a typical 0dBm transmitter (TX) [1], BLE suffers from a limited link budget, susceptibility to jamming in the congested 2.4GHz band, and suboptimal bandwidth utilization. BLE supports a maximum 2Mb/s data rate over 40 channels, whereas Bluetooth Classic Basic Rate/Enhanced Data Rate (BT-BR/EDR) supports up to 3Mb/s in 79 channels [3] but dissipates high power due to stringent C/I and non-constant envelope modulation
