Frequency reuse is the practice of splitting an area into smaller regions that do not overlap so that each utilizes the full range of frequencies without interference. The introduction of this concept was a major step in the development of mobile phone technology.Know More
Before the advent of cellular phones, radio telephones and other mobile communications devices relied on a single, central antenna tower to service an entire city. Each phone required a large antenna powerful enough to transmit a signal over the potentially great distance to that tower. In addition, there was a limit to the amount of phone traffic that could be supported at a given time because each tower only offered a limited number of channels.
Researchers then realized that they could increase the cap on the number of simultaneous users by applying their current technology to a smaller scale. Accordingly, they introduced frequency reuse. Mobile communications providers increased the total number of towers and reduced the size of each one's service area. Although each tower had a limited number of channels, the non-overlapping nature of the service areas allowed the same frequency to be used in each one without interference. By doing so, mobile communications providers greatly expanded the number of potential users.Learn more about Optics & Waves
The pitch of a sound is the ear and brain interpreting the frequency of the sound. When there is a high frequency, the ear interprets the sound as a higher pitch, and when the frequency is low, the ear hears a low pitch. Pitch has been standardized and uses "cents" as a unit of measurement.Full Answer >
A carrier frequency is a technical term used to describe a frequency that is generated by a transmitter such as a radio or radar transmitter. A carrier frequency is sometimes known as a resting or center frequency.Full Answer >
Pitch refers to the frequency of a sound, while loudness refers to the size or amplitude of the sound. Every sound has both a specific pitch and loudness.Full Answer >
The formula for finding the velocity of a wave is to multiply its wavelength by its frequency. In this case, 30 m x 12 Hz = 360 meters per second.Full Answer >
