Some disadvantages of wireless communication include a limited amount of bandwidth for communication and breaches of network security. Wireless transmissions can be seen or heard by others on the network, unless security is set so that only registered devices within the network are able to receive data.
The lack of security is often why a user will receive a pop-up on an open wireless network that is unsecured. Personal information, such as passwords, are easily viewable by others on the network if they decide to do so. However, with secure and password-encrypted networks, the risk of this type of security breach is much less.
Wireless networks require many radio signals to power them. In areas where there is not an adequate signal, bandwidth will be constrained. Wireless communication bandwidth is fairly widespread in modern times, but areas still exist where the possibility of having too many users at once could be an issue.
There are also many advantages of wireless communication, such as quality transmission speeds. Another advantage of wireless communication is mobility. Wireless networks and devices allow the user to move from place to place with their device while still acquiring a signal. Wireless networks are also self-configuring, for ease of use.
