A walkie talkie is a handheld radio with a speaker and microphone that enables two people to communicate with each other in a situation where they cannot physically be together. These radios are also known as two-way radios. Business walkie-talkies generally have higher frequency levels and longer ranges than consumer models. These devices are generally more expensive than their consumer counterparts. In addition, a business radio typically has more features and is heavy-duty. However, a consumer radio is less expensive and has lower frequency levels. It is also battery-operated, and the batteries vary depending on the model.
The basic components of a walkie-talkie are a triode amplifier, three “chokes” (frequency filters), and a capacitor. The US Patent 2,698,380 describes a high-frequency transmitter and receiver. This illustration is owned by the US Patent and Trademark Office. In order to use a walkie talkie, you need to have the right frequency bands and the correct channel.
A walkie-talkie is also useful in outdoor sports. A number of sports do not have range issues, but there are some that do. Skiing, for example, requires that both you and your partners have adequate range on the same side of the mountain. If the mountain is in the way, the signal will be blocked and the two people cannot communicate with each other. However, a walkie-talkie will help you stay in contact no matter where you are.
