LTE Applications [2]

Introduction

Cellular standards and networks have traditionally been optimized for the high throughput requirements of modern smartphones. Recently the Internet of Things (IoT) has emerged as a new application with vastly different requirements. Ericsson predicts, that there will be 15 billion smart devices with Internet connectivity. Potential applications include smart metering, tracking in logistics, environmental sensing, and smart buildings. Two new variants of LTE have been standardized as part of Release 13 in 2016 for this kind of device [1]: LTE Cat-M1 (eMTC) and NB-IoT. They both offer reduced cost and power consumption, as well as improved coverage, but Cat-M1 supports more features and has a higher maximum throughput. As part of our communication platform, we are currently developing a modem, which supports both standards, at IIS.

One of the key features of cellular communication is switching to another cell if it provides better service. To enable this functionality, the device must be able to measure multiple neighbouring cells while also performing regular communication tasks. In LTE this includes measuring the received power level and SINR of multiple cells on the same, or different carrier frequency.

Project Description

During the first part of this project, you will study the requirements and existing neighbour cell measurement techniques. Based on this, you will develop a method to perform neighbour cell measurements in an LTE Cat-M1 device. You will extend our existing Matlab simulation framework and run simulations to verify the performance of your algorithms.

Depending on the duration of the project, you can also realize a hardware-implementation and verify it on our FPGA testbed.
