Wireless networks allow multiple users to access large amounts of information without the hassle of running wires to and from each computer. This can be extremely helpful if there are a number of users that need to move around and/or access the network. However, wireless networks are far from perfect and there are a number of disadvantages that an individual or organization may face when using a wireless network.
Wireless networks are typically inexpensive, but it can cost up to four times more to set up a wireless network than to set up a wired network in some cases.
The range of a wireless network is limited and a typical wireless router will only allow individuals within 150 to 300 feet to access the network.
Wireless networks are extremely susceptible to interference so radio signals, radiation and any other similar type of interference may cause a wireless network to malfunction.
Wireless networks can be accessed by any computer within range of the network's signal so information transmitted through the network (including encrypted information) may be intercepted by unauthorized users.
Wireless networks are typically slower than wired networks, sometimes even up to 10 times slower.
