Today we can observe the rapid rise of technologies and their interference in multiple spheres of human activity to improve results and achieve higher efficiency levels. Another important domain for their application is the enhancement of communication between agents in different locations. The evolution of the Internet became one of the key factors that fostered this process and preconditioned the further development of technologies. In the modern world, the Internet is closely connected with wireless LAN (WLAN) protocols that are used to transfer data without traditional ways presupposing cables. However, it can suffer from channel fading or external interference, which means the need for an efficient tool to avoid these problems.
Background
WLAN becomes an advantageous way to use modern technologies and preserve access to the Internet not being limited by the cable and demonstrating high mobility. It emerged in 1971 as the first wireless computer network at the University of Hawaii. Since that time, it had passed a long way and became a popular means of transferring data. However, there are also several problems associated with the protocol that can be taken as its disadvantages. First of all, the issue of channel fading becomes topical. It can be determined as the variation of the attenuation of a signal that emerges under the impact of multipath propagation or wave propagation. It can significantly corrupt the quality of data transfer and prevent individuals from using the Internet and LAN. Another problem peculiar to wireless networks is the high risk of external interference. The opportunity for the breach appears because of the nature of this technology as malefactors can use it to enter the private network and analyze information presented there.
Purpose and Research Question
Under these conditions, the pivotal aim of the project is to investigate Wireless LAN, the problem of channel fading, and external interference to find an appropriate solution that can be used to minimize risks and align an efficient functioning of the system. It means that the existing tools to prevent fading such as diversity schemes and rake receivers along with the shielding and improved security measures to minimize security risks will be discussed. Regarding the central topic of the research, the following research question can be formulated:
What are the specific technologies and software that can solve the problem of channel fading and external interference and improve the functioning of WLAN?
Methodology
The given research question presupposes the use of a particular methodology to conduct an in-depth analysis of the issue and acquire credible data. Investigation of the efficiency of specific technologies and their impact on the work and stability of WLAN presupposes an analysis of research papers and articles to understand how these approaches might help to solve the problem and how they impact the discussed aspects. For this reason, the literature review becomes one of the central methods utilized in the project. At the same time, internet sources should also be investigated to collect data about the problem and discuss it.
Relevance
Altogether, the given project is focused on the in-depth investigation of WLAN as one of the modern technologies that guarantee increased convenience and provide users with high mobility. The work will contribute to the improved comprehension of the basic characteristics of this protocol and how such problems as channel fading and external interferences might impact its usability and reliability. The topicality of the selected area is evidenced by the growing number of devices using WLAN and its utilization in all spheres of human activity.
