Get an Original EssayRather than wires and physical connections, "radio waves and frequencies" are used as a means of communication between devices to transmit and share data with each other also includes Internet access points. It makes it very easy for the user to move around the coverage area of ​​these radio waves without losing internet connection or any interruption. In the mid-90s it was absolutely impossible to use WLAN everywhere as it was very expensive and was only used in cases where physical network connections were not possible. But a great evolution has been observed in the field of WLANs. Each WLAN participant falls into one of these two categories, for example access point or client. There are still four main types of wireless networks available in the world. These include LAN, WAN, MAN, and PAN. Radio frequency based network involves two main components which are the sender and receiver of the waves. Here electromagnetic waves are sent and received via the sender and receiver respectively. Radio waves can travel in all directions as ripples which help form the coverage area of ​​the wireless network. Wireless Security Basics Understanding frequencies is very important for the company's IT manager to meet security challenges. By knowing the frequency of the equipment used, the IT manager has the right to know what level of interference can cause distortion in the system and could cause disruption or facilitate any hacking attack. If a hacker attempted to block one frequency, the system could switch to the other. Wireless Network-Related Security Threats As the wireless network has evolved and is now available everywhere, it has also brought with it few built-in threats associated with data protection and unauthorized accessibility. Unfortunately these wireless network systems are highly vulnerable to security risks as physical barriers cannot be formed to make the setup more secure and threat-free. This unauthorized access could damage your devices, hack your confidential information, and misuse your wireless network system. Please note: this is just an example.
