Universal Multi-Rat Tester For Mmtc Applications
 Juráň, Radovan ; Možný, Radek
While the IoT has made significant progress along the lines of supporting its individualapplications, there are many massive Machine-Type Communication (mMTC) scenarios in which theperformance offered by any single Radio Access Technology (RAT) available today might be insufficient.To address these use cases, we introduce the concept of multi-RAT tester, which implies theavailability and utilization of several RATs within a single IoT device. We begin by offering insightsinto which use cases could be beneficial and what the key challenges for mMTC implementation are.We continue by discussing the potential technical solutions and employing our own prototype of amulti-RAT device capable of using different Low-Power Wide-Area (LPWA) communication technologies.It is assumed that use of multiple radios simultaneously will lead to overall improvementof communication parameters by leveraging the synergy between RATs. The novel vision enabledby the multi-RAT concept in this work could be impactful across multiple fields and calls for crosscommunityresearch efforts in order to adequately design, implement, and deploy future multi-RATmMTC solutions.

Suitability Of The Lorawan Technology For Massive Machine-Type Communication
 Mašek, Petr
A remarkable progress in the LPWAN (Low PowerWide Area Network) technologies overthe recent years opens new opportunities for developing versatile massive IoT (Internet of Things)applications. In this paper, we focus on one of the most popular LPWAN solutions operating in thelicense-exempt frequency bands, named LoRaWAN (Long Range Wide Area Network). The keycontribution of this work is the implementation of the LoRaWAN technology within the NetworkSimulator 3. The collected simulation results reveal the expected spectrum utilization within theunlicensed band as well as show the transmission success rate for different communication distancesbetween end-devices and LoRaWAN gateways.
