Keep up with 5G TN/NTN standardization
Ensure compatibility with the latest 3GPP developments related to 5G, 5G-Advanced, and 6G TN & NTN.
ALIX is a 5G TN/NTN system-level simulator that is used for detailed protocol level simulations for 5G Terrestrial and Non-Terrestrial Networks.
Operating on a packet level resolution, ALIX makes it possible to evaluate communication technology performance, keep up with 3GPP 5G TN/NTN standardization efforts, and explore future technologies such as 5G-Advanced and 6G NTN.
Ensure compatibility with the latest 3GPP developments related to 5G, 5G-Advanced, and 6G TN & NTN.
For example: performance differences between DVB-S2X and 5G NR.
Optimize, refine, and develop your future network systems.
Magister has developed the ALIX simulator through projects with the European Space Agency and the European Union, and our internal development work.
These projects include, for example, ALIX, SAIRCC, HELENA, and DYNASAT (EU Horizon).
Co-existence of Terrestrial and Non-Terrestrial Networks on Adjacent Frequency Bands
Co-existence of Terrestrial and Non-Terrestrial Networks on Adjacent Frequency Bands/ Lauri Sormunen, Henrik Martikainen, Jani Puttonen, Dorin Panaitopol, The 11th Advanced Satellite Multimedia Conference and the 17th Signal Processing for Space Communications Workshop (ASMS/SPSC), 6–8 September 2022.
This paper presents the latest achievements concerning 3GPP Release-17 adjacent band coexistence simulation work on 5G new radio non-terrestrial networks (NTNs) for satellite communications.
The main conclusions can be summarized as follows: (1) NTN UE can reuse the current requirements of the TN UE, (2) the satellite connectivity does not require a dedicated satellite waveform, and (3) TN can co-exist with NTN on adjacent channels with relaxed ACIR requirements for the tested simulation scenario.
A System Simulator for 5G Non-Terrestrial Network Evaluations
A System Simulator for 5G Non-Terrestrial Network Evaluations / Jani Puttonen, Lauri Sormunen, Henrik Martikainen, Sami Rantanen, Janne Kurjenniemi, IEEE International Symposium on a World of Wireless, Mobile and Multimedia Networks (WoWMoM), Non-Terrestrial Networks in 6G Wireless workshop, June 7-11, 2021.
The 3rd Generation Partnership Project (3GPP) is working on the specifications related to the 5G satellite component, i.e., 5G Non-Terrestrial Networks (NTN). 5G NTN specifications can be used to build different spaceborne or airborne 5G systems.
This article presents a 5G NTN extension to an open-source Network Simulator 3 (ns-3) and its 5G extension (5G LENA). The objective is to use the resulting System Level Simulator (SLS) in 3GPP standardization to evaluate different system concepts and parameterizations.
Multi-Connectivity in 5G and Beyond Non-Terrestrial Networks
Multi-Connectivity in 5G and Beyond Non-Terrestrial Networks / Mikko Majamaa, Henrik Martikainen, Lauri Sormunen, and Jani Puttonen, Journal of Communications Software and Systems, 2022.
The Fifth Generation (5G) communications systems aim to serve such service classes as Ultra-Reliable Low Latency Communications (URLLC), enhanced Mobile Broadband (eMBB), and massive Machine-Type Communications (mMTC).
To meet the growing requirements posed to mobile networks, satellites can be used to complement the Terrestrial Networks (TNs). To increase the efficiency of the satellite communications involved, bandwidth-efficient techniques should be used. Multi-Connectivity (MC) is one such technique. In MC, a User Equipment (UE), for example, a smartphone, can be connected to multiple Next Generation Node Bs (gNBs) simultaneously.
In this paper, an adaptive MC activation scheme for throughput enhancement in 5G and beyond Non-Terrestrial Networks (NTNs) is presented. The algorithm is evaluated by system simulations using different traffic split algorithms, namely, even split, data request per connection and per gNB algorithms. In the considered simulation scenario, the maximum throughput enhancement of 9.1%, compared to when MC is turned off, is experienced when using the adaptive Secondary Node (SN) addition algorithm with the combination of the data request algorithms.
