There are basically three different types of wireless networks – WAN, LAN and PAN: Wireless Wide Area Networks (WWAN): WWANs are created through the use of mobile phone signals Wireless security is the prevention of unauthorized users from accessing your wireless network and stealing the data using your Wi-Fi network. To be precise, wireless security ensures protection to a Wi-Fi network from unauthorized access.typically provided and maintained by specific mobile phone (cellular) service providers. Wireless Networking is any kind of computer network that mainly utilizes wireless data connections for uniting system hubs. Usually wireless telecommunications are employed and implemented in OSI Model Network structure using radio communications. The best examples of wireless networks include cell phone networks, Wi-Fi local networks and terrestrial microwave networks. Various types of wireless networks are Wireless personal area networks (WPANs) - that is within a person's reach; A wireless local area network (WLAN) joins two or more gadgets over a short distance utilizing an internet access; A wireless mesh network is a wireless network made up of radio nodes; Wireless metropolitan area networks WMAN mainly connects several wireless LANs; Wireless wide area networks is the connection between towns and cities. Journal Article is sometimes called a Scientific Article, a Peer-Reviewed Article, or a Scholarly Research Article.
