Advantages
Mobility - user device can be moved easily within the wireless range
Neat and easy Installation - since no cable running here and there, just start up the wireless device and you're ready to rumble
Less cost for cabling infrastructure and device
More user supported - cable device have limited slots whereas wireless does not.
Disadvantages
Relatively lower bandwidth speed - example: although currently 802.11/n could reach 128 Mbps, UTP cable can reach 1 Gbps. And more user mean each bandwidth get smaller. That is why currently wired backbone network is still preferred.
Ease of access means more security also necessary to protect data and/or bandwidth, since people can connect anywhere within range without seeking network plug.
