Wireless Networking


A wireless network is a computer network that uses radio signals at the physical layer. This results in a fundamentally different paradigms for wireless networking, as the links, the foundation of traditional networking, become a blurred notion. In terms of classification, there are single-hop and multi-hop as well as infrastructure-based and infrastructure-less wireless networks. Examples include wireless local area networks (e.g., 802.11), wireless personal area networks (e.g., Bluetooth), cellular networks, etc.
