Dual Band
3 Mobile uses 6 main frequencies. Three of them are Telstra, two are Vodafone and the last is their home frequency.
The tone frequencies, are selected such that harmonics and intermodulation products will not cause an unreliable signal. No frequency is a multiple of another, the difference between any two frequencies does not equal any of the frequencies, and the sum of any two frequencies does not equal any of the frequencies.
To compare two-way frequencies in a relative frequency table, you first convert the counts in the table into relative frequencies by dividing each cell by the total number of observations. This allows you to express the frequencies as proportions, making it easier to compare different categories across the two variables. You can then analyze patterns, such as which combinations of categories are more or less common, by examining the relative frequencies rather than absolute counts. This approach helps highlight relationships and trends in the data.
Within a speaker different drivers handle different frequency ranges. A two way speaker has different drivers handling two frequency ranges; in this case a woofer for the low freqs and a tweeter for the high freqs. A 3 way speaker also has a midrange to handle the middle frequencies.

The beat frequency in a system with two sound waves of slightly different frequencies can be calculated by subtracting the frequencies of the two waves. The beat frequency is the difference between the two frequencies, which creates a pulsating sound when heard together.

The term for the distance between two sound frequencies or pitches is called "interval."
No.
Two types used at microwave frequencies are gunn and PIN diodes.
If you are using an amp for this than you may be experiancing "engine noise". Or you may be pushing more power through the speaker than they can handle. In most cases "static" is distortion in the translation from electrical frequencies to sound frequencies.
