Public WiFi is any network connection that doesn't require a pass code or key code to access. They are open to anyone who is within range. Devices such as cell phones, tablets and laptops will pick up a signal and begin to connect with it if their WiFi setting is turned on. It makes no difference if the signal is being transmitted from a person's home, the local coffee shop or a local business.
The question of safety is always on your mind when dealing with your children and your financial information. With more and more teens having internet capabilities on their cell phones and other devices, parents are concerned with the safety of public WiFi networks. The problem is not with the networks, so much as with the devices being used to connect with it.
