Small footprint and low power nodes are indispensable for the billion devices Internet-of-Things.


By the end of the decade billions so called Internet-of-Things (IoT) devices will be connected to the Internet. IoT nodes can range from electrical energy meters to tiny positioning nodes connected to a cellular network. In particular the latter require low power consumption and low footprint. To this end, the 3GPP standardization committee specified a new user equipment category (Cat-0) for low complexity IoT devices in release 12 [1]. The low complexity is achieved by single receive antenna and 1.4 MHz bandwidth requirements. A further bandwidth reduction down to 200 kHz may be considered for release 13 [2].

Project Description

In this project, the base for the development for an LTE release 12 and release 13 based IoT module shall be established. A commercially available LTE RF transceiver can be used to extract baseband I/Q samples onto an FPGA testbed. Preliminary synchronization as well as FFT computation shall be implemented and tested.

Status: Completed
