Abstract:The feasibility of a reconfigurable LPWAN node is discussed. A proof of concept is presented for an optimum solution that is reconfigurable yet comparable with the price and power consumption of available LPWAN nodes. The proposed solution is capable of following features: •SDR-based standalone module •Supports sub-1Ghz band •Max Bandwidth 600 kHz •Cost<§30 • PCB area of the design less than 5x5 cm2 •low power consumption •GPIO capability for interfacing sensors A three-chip solution is found to be feasible for the intended reconfigurable node. In a three chip design an FPGA performs data rate conversion and filtering, while a microcontroller performs the baseband processing. An RF transceiver chip is attached to the FPGA for data transmission and reception in sub-1Ghz band.
