Wireless LAN is the type of network that does not involve cables or physical connectivity of devices to achieve networking. This helps avoid the introduction of expensive hardware included in conventional networks. Say no to plagiarism. Get a tailor-made essay on “Why violent video games should not be banned”? Get an original essayRather than cables 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 hotspots. This allows the user to move very easily within the coverage area of ​​these radio waves without losing the Internet connection or any interruption. In the mid-90s, it was completely impossible to implement WLAN everywhere because it was very expensive and was only used in circumstances where physical network connections were not possible. But a big evolution has been observed in the field of WLAN. Each WLAN participant belongs to one of two categories, namely the access point or the client. There are still four main types of wireless networks available in the world. These include LAN, WAN, MAN and PAN. Radio frequency based networks involve two main components which are the transmitter and receiver of the waves. Here, electromagnetic waves are sent and received through the transmitter and receiver respectively. Radio waves can propagate in all directions in the form of ripples that help form the coverage area of ​​the wireless network. Wireless Security Basics Understanding frequencies is very important for the enterprise IT manager to deal with security challenges. By knowing the frequency of the equipment deployed, the IT manager has the right to know what level of interference may cause distortion in the system and could cause jamming or facilitate any hacking attack. In the event that a hacker attempts to jam one frequency, the system could switch to the other. Security Threats Related to Wireless Networks As wireless networks have evolved and are now available everywhere, they have also brought few built-in threats associated with data protection and unauthorized accessibility. Unfortunately, these wireless network systems are very vulnerable to security risks because no physical barrier could be formed to make the installation more secure and threat-free. This unauthorized access could damage devices, hack confidential information, and misuse the wireless network system. Keep in mind: this is just a sample.
