Network Design and Optimization

By Vikram Singh
Wireless communication network consists of two parts (network infrastructures), the radio access network (RAN) and core network (CN). 4G-BWSim and 5G-BWSim focus on the RAN infrastructure which consists of three layers L1, L2 and L3. 4G simulator can simulate all the three layers whereas the 5G simulate the layer 1 end to end and elements of layers 2 and layer 3 but not complete layers. Both these simulators allows the designers/developers design the algorithms for radio access network but also optimize the methods/algorithms based on their customers need. Consider an example, an algorithm designed for mobile broadband may not be the best for IoT applications because the for mobile broadband applications the objective of algorithm design is to maximize the data-rate/throughput whereas for IoT applications data rate requirements are often low instead the power consumption is a major concern. Similarly, the protocols and algorithms designed for outdoor applications might not be the best for Indoor factory/gaming/V2X application. Hence, the terrain, scenario and use-cases plays a crucial role while designing the algorithms. The terrain and cell size are often captured by the channel model. In channel models, the small-scale parameters and large-scale parameters are calculated from data collected from a specific terrain. These parameters are characterized by the probability distribution function, mean value and the standard deviation. To make these channel model realistic these parameters maintain inter-parameter correlation, spatial consistency and correlation across space and time. On the other hand, the cell size has constraints on the base-station transmit power as the path-loss is lower and line of sight probability is higher in small cells (micro) compared to large (macro) cells. To design the whole network, the designers test their algorithms, protocol stacks and procedures implemented for different layers of the network using simulators.
These simulators helps in identifying following:
GigaYasa Wireless has designed system level simulators for 4G and 5G networks, called BWSim-4G and BWSim 5G-R15 respectively. Both our simulators are very helpful in simulating the networks for wide varieties of use-cases, terrains and capabilities.

career and higher studies
The internship program not only provides scholars with hands-on experience in the field of wireless technology but also offers them a unique opportunity to join the organization as full-time Wireless Researchers upon completion of their internship. Furthermore, Gigayasa's location within the IITM Research Park allows scholars to apply for higher studies at IIT Madras, directly, without going through any entrance exam, while simultaneously continuing their work as part of our team. This affords researchers the opportunity to pursue advanced courses in parallel with their research work, facilitating a well-rounded development of their skills and knowledge.

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.
