Achieving Harmony Among Wireless Networks Sharing Radio Resources (Uzyskanie harmonii w działaniu sieci bezprzewodowych korzystających ze wspólnych zasobów radiowych)
English

Various radio access technologies are beginning to compete for license-free frequency bands. The most notable is the well-established Wi-Fi technology (based on IEEE 802.11), while the newcomer is LTE in its various unlicensed versions. LTE operators around the world are interested in utilizing the unlicensed bands to deal with the problem of licensed bandwidth shortages and growing user expectations and needs (high throughput, low latency). These operators perceive license-free bands as a great opportunity to increase their earnings. On the other hand, Wi-Fi vendors are afraid of the new competitors, who may lower the popularity of Wi-Fi devices in the future. Therefore, this is certainly one of the hottest telecommunications-related topics, which is widely discussed by researchers and scientists (from both industry and academia) around the world and is motivated by the high competition on the market.
 
Comparing Wi-Fi and LTE-based technologies it terms of accessing the channel in license-free frequency bands, both aim to grasp as much radio resources as possible while coexisting with other channel users. Each technology has its advantages, however, its operation and performance boundaries are well known only if we have a single network type operating in isolation. In case of several competing technologies, the observed performance is often unexpected and surprising (i.e., different phenomena are observed which are hard to predict). This leads to the following general research problem: how can harmony be achieved among wireless networks sharing radio resources? In particular, the interactions between networks using scheduled-based access (such as LTE) and using a combination of scheduled and random access (such as the upcoming 802.11ax) are an important future research topic. Our goal is to study the interactions between such technologies in hopes of gaining new knowledge and answering research questions of a more general nature. In particular, we want to provide solutions that will allow fairness in radio resource sharing while maintaining efficiency in terms of channel utilization.
