Wireless Networking Joe Lee Dan Zakula

Why is it better than wired? Less hassle with wiring Less hassle with wiring Mobility Mobility Easily change networks without changing wires Easily change networks without changing wires

Advantages/Uses Doctors and nurses in hospitals are more productive because hand-held or notebook computers with wireless LAN capability deliver patient information instantly.

Network managers in dynamic environments minimize the overhead of moves, adds, and changes with wireless LANs, thereby reducing the cost of LAN ownership.

Disadvantages Open broadcast Open broadcast The average cost per node for a Ethernet connection is $150 to $300 per node and the average cost per node for a wireless connection ranges from $500 to $1,000 depending on the wireless technology used. Most buildings are already wired for communications unless you plan on several moves and relocations. Access points cost around $1800 and adapters are around $600 with potential speeds of up to 2 megabits per second.

How does it work? Usually need to have a Wireless Router/Switch Usually need to have a Wireless Router/Switch All nodes need to have Wireless network interface device. All nodes need to have Wireless network interface device. Router/Switch broadcasts to all nodes within area. Router/Switch broadcasts to all nodes within area. 902megahertz to 928 megahertz is the frequency set aside by the federal communication commission in 1985 for the ISM industrial, scientific, and medical band-frequency referred to as the garbage band because of all the spectrum hogging equipment that already uses it -example commercial radio, television, and cellular phones. 902megahertz to 928 megahertz is the frequency set aside by the federal communication commission in 1985 for the ISM industrial, scientific, and medical band-frequency referred to as the garbage band because of all the spectrum hogging equipment that already uses it -example commercial radio, television, and cellular phones.
