Features

Graphical Users Interface

The Simulator is integrated with a graphical user interface (GUI) which simplifies the process of configuring numerous interrelated parameters in 5G for the simulations. The GUI provides visual feedback for errors in a parameter input and captures the relations and dependencies between the parameters to assist you in setting the configurations. The Simulator allows the users to run multiple simulations one after another manually or automatically and to compare the results side by side in a single plot.

5G uses forward error correction at the transmitter and adapts modulation and code rate (link adaptation) to counter the volatility and dynamic nature of wireless channels.

Adaptive Networks

5G uses forward error correction at the transmitter and adapts modulation and code rate (link adaptation) to counter the volatility and dynamic nature of wireless channels. Simulator implements the link adaptation using a standardized parameter termed channel quality index (CQI). Further, the Simulator’s rank adaptation feature allows the transmitter to select the suitable number of layers for SU-MIMO and MUMIMO to avoid degradation from transmitting too many layers.

Simulation Key Performance Parameters

  • Link Level Simulation
In link level simulations, the users control the signal to noise ratio (SNR) of the link and evaluate the performance including Bit error rate (BER), Spectral Efficiency, Block Error Rate (BLER) and Throughput.
  • System Level Simulation​
System level simulations compute Cumulative Distribution Function (CDF) of Throughput/Spectral Efficiency/BLER, Spectral Efficiency etc. to evaluate system performance.
  • Multi-cell Simulation
Multi-cell simulation computes parameters related to channel/link including CDF of Transmit Antenna Gain, Link Gain, Channel Gain, Signal to Interference and Noise Ratio (SINR), Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ).

Antenna Models​

Antenna radiation pattern plays a crucial role in Massive MIMO’s ability to exploit spatial multiplexing and beamforming gain. The tool allows simulation using parabolic and omni directional antennas. However, custom antenna patterns can also be configured for evaluation using system level simulations.​

Multiple Input Multiple Output (MIMO) Systems

5G networks can spatially multiplex multiple layers/streams by exploiting massive MIMO and can be equipped with hundreds of antennas. MIMO implementation requires the availability of Channel State Information (CSI) which can be acquired either based on reciprocity or based on feedback, along with Codebook Type I & Type-II all of which are supported by Simulator.

System Terrains​

3GPP has defined different indoor and outdoor terrains for study and evaluation including Rural Macro, Urban Macro, Urban Micro, Indoor Hotspot and Indoor Factory. Simulator supports all these terrain channel models including hexagonal & rectangular layouts as well as inter-site distance, base-station heights, number of sites and UE distribution.​

publication of research papers
Collaborating with Gigayasa can provide research scholars with access to cutting-edge technology and resources, which can enhance the quality and impact of their research. By partnering with us, scholars can benefit from the company's expertise in simulation technology, as well as its access to advanced computational resources and software tools. In addition to gaining access to these resources, research scholars who collaborate with us can also contribute to the development of new simulation methods and techniques, which can benefit us and the wider scientific community. One of the key benefits of collaborating with us is the potential for co-authorship and joint publication. By working together on research projects, scholars can produce high-quality publications that are jointly authored by both parties. Furthermore, we provide guidance to research scholars on publications in international journals, with the expectation that the scholars will cite and credit Gigayasa's simulation tool in their papers.
corporate training and incubation
Gigayasa is committed to advancing the field of 5G technology and promoting innovation in various industries. As part of this commitment, Gigayasa offers commercial licenses to academia, which provides various benefits to academic institutions and to the startups incubated through them. With the commercial license, academic institutions can utilize the 5G-Toolkit and BWSim-5G license for commercial purposes, including corporate training programs. Faculty members can utilize these simulation tools for delivering high-quality corporate training programs, either within their campuses or at corporate campuses. Additionally, the commercial license also enables academic institutions to offer the license/products to startups availing Institute's lab facilities. Startups can leverage the 5G-Toolkit and BWSim-5G license to develop and test their products, enabling them to accelerate their development process.
intellectual propery and patents
Intellectual property (IP) is a critical aspect of research collaboration, particularly in deep tech areas where we operate. We recognize the importance of IP and have developed a policy for IP ownership and sharing for work outputs that come through research collaboration. Under this policy, Gigayasa will file IP for work outputs that come through research collaboration. The institute will be a co-applicant in the IP, which means that they will have shared ownership of the IP. This provides the institute with legal protection over the IP and allows them to mention it in any medium, such as research papers or publications. The institute is free to use the IP for any of its research or publications, except for competing purposes or for commercializing the same. Gigayasa will use the IP for its own commercial purposes without any royalty payment to the institute. However, if we sell or sublicense the IP, then a share of the royalty would be paid to the institute.
Internships
Gigayasa recognizes the importance of internships in developing the next generation of researchers and offers internships ranging from 2 to 6 months in wireless communications. The internships offered by Gigayasa are a great opportunity for research scholars to gain hands-on experience in the field of wireless communications and contribute to its advancement. The internships offered by us are paid, and the stipend is in accordance with the norms of the institute. Our internships are also an opportunity for research scholars to network with experienced professionals in the field of wireless communications. This can be invaluable in building relationships that can lead to future job opportunities or collaborations.
