Centralized RAN for Future Low-Power Wide-Area Networks: A LoRa Case Study
Joachim Tapparel, Amavi Dossa, El Mehdi Amhoud +1
In recent years, low-power wide-area network (LPWAN) technologies have gained significant traction as a connectivity option for Internet of Things (IoT) applications. While these n…
Dataset and UAV Propagation Channel Modeling for LoRa in the 860 MHz ISM Band
Joachim Tapparel, Andreas Burg
LoRa is one of the most widely used low-power wide-area network technology for the Internet of Things. To achieve long-range communication with low power consumption at a low cost,…
LoRa Fine Synchronization with Two-Pass Time and Frequency Offset Estimation
Joachim Tapparel, Andreas Burg
LoRa is currently one of the most widely used low-power wide-area network (LPWAN) technologies. The physical layer leverages a chirp spread spectrum modulation to achieve long-rang…
A Maximum-Likelihood-based Multi-User LoRa Receiver Implemented in GNU Radio
Mathieu Xhonneux, Joachim Tapparel, Orion Afisiadis +2
LoRa is a popular low-power wide-area network (LPWAN) technology that uses spread-spectrum to achieve long-range connectivity and resilience to noise and interference. For energy e…
On the Advantage of Coherent LoRa Detection in the Presence of Interference
Orion Afisiadis, Sitian Li, Andreas Burg +1
It has been shown that the coherent detection of LoRa signals only provides marginal gains of around 0.7 dB on the additive white Gaussian noise (AWGN) channel. However, ALOHA-base…
An Open-Source LoRa Physical Layer Prototype on GNU Radio
Joachim Tapparel, Orion Afisiadis, Paul Mayoraz +2
LoRa is the proprietary physical layer (PHY) of LoRaWAN, which is a popular Internet-of-Things (IoT) protocol enabling low-power devices to communicate over long ranges. A number o…
