A frequency is the number of occurrences of a repeating event per unit time. It is most commonly thought of as a wave that goes from one place to another. The up and down crests of the wave as it moves along would be the repeating occurrences. If you change the speed of the up and down crests of the wave, you change the frequency.

The types of waves up and down are essentially cell phones use radio waves. Most cell phone carriers typically get 832 radio frequencies to use in a particular city. Cell phone scanner frequencies are usually used in sets of two. Each cell phone uses two frequencies for call. This is known as a duplex channel. Consequently, there are typically 395voice channels per carrier.

Therefore, each cell has about 56 voice channels available. In other words, in any cell, the cell phone scanner frequencies can have 56 people talking on their cell phone at one time. These older and more basic analog cellular systems are considered first-generation mobile technology, or 1 g. With the introduction of digital transmission methods about 10 years ago (2 g), the number of available channels increases. This was known as 2 g. And now we have 3 g or third generation networks. This dramatically increases the number of channels.

Although cell phone scanner frequencies have increased, cell phones have low-power transmitters in them. Many cell phones are less powerful than the old CB radios. This does have some advanTAGes. The lowpower transmission means that the cell phone can use smaller batteries. Also, phone call transmissions stay within a city cell, near a cell tower. This means that the same cell phone scanner frequencies can be used over again in different parts of the city.

The cellular approach requires a large number of base stations in a city of any size. A typical large city can have hundreds of cell towers. But because so many people are using cell phones, costs remain low for user. Each carrier in each city also runs one central office called the Mobile Telephone Switching Office (MTSO). This office handles all of the phone connections to the normal land-based phone system, and controls all of the base stations in the region.
