Frequency is a unit of measurement that measures the number of times that an event happens. It is often referred to as temporal frequency, contrasting with spatial or angular frequency. The most common uses for frequency are in music and mathematics. Here, we will consider the definitions of temporal, spatial, and angular frequencies. In this article, we will examine some of the most important definitions and examples. We will also explore the meaning of the term "frequency" and how it differs from the other three.
Radio frequencies travel along a "line-of-sight" path. However, this does not mean that they can't travel through objects that aren't made of metal. In addition, radio waves can bounce off surfaces, so some people use GMRS handsets without getting a license. Therefore, if you are considering GMRS licensing, it is wise to consult your wireless dealer and understand the legal implications. Remember that if you are using a GMRS handset, you must have a license.
The UHF band has different characteristics than HF CB+ bands. FRS are not the same. Because of this, the radio propagation is not as predictable. For short-range communications, FRS may be a better choice than powerful license-free radios that operate in the HF CB band. It's important to note that the FCC does not require a license for FRS. This is the only restriction that applies to this type of radio.
