Licensed and Unlicensed Walkie Talkies
Walkie talkies come in two basic types. One type is referred to as licensed, while the other type is referred to as unlicensed. A "licensed" set of walkie talkies will transmit conversations over a radio frequency that has been isolated and designated specifically for that particular set of walkie talkies. This type of walkie talkie would be the type that you would see a pit crew at a car race communicating with their driver with.
Right Off an Electronics Store Shelf
Unlicensed Walkie Talkies would be the type of walkie talkie that you can buy off the shelf at any electronics store. While there is an extremely small chance of it, you can run into situations with unlicensed walkie talkies where unrelated walkie talkie users using completely different walkie talkies can over ride each other and cause a confusing situation. This is precisely the reason why licensed walkie talkies are available for professionals who can't afford the risk of these types of situations.
