Wireless Local Area Network Background The first wireless computer communication network ALOHAnet (operational in 1971) was developed by Norman Abramson‚ a professor at the University of Hawaii. At first‚ the wireless LAN was so costly that it was just used as an alternative to the places where the cabling was difficult or impossible. Recent developments included industry specific solutions and proprietary protocols‚ but were replaced by various versions of IEEE 802.11. In 2009‚ 802.11

Unit 5. Lab. New Building-Wired and Wireless If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance
