The way the signal is transmitted will depend on whether the bands use FDD or TDD techniques: Once your phone is activated, it automatically connects to your carrier's 4G, LTE, and 5G frequencies. Nowadays, most phones are built to support a wide range of frequencies, so that isn’t much of a problem. For a cellular device to work, it must be compatible with those specific frequencies. How Do Cellular Frequency Bands Work?Įach carrier owns lots of frequencies to cover multiple areas and people. To deliver the most reliable network, carriers buy multiple FCC licenses throughout the RF spectrum. Thus, they are better for metropolitan and urban areas. They can, however, transmit more data at a faster rate. On the other hand, higher frequencies can’t travel as far or penetrate obstacles as well.

This makes them great for rural and remote areas. Lower frequencies can travel far and penetrate obstructions pretty well. They can consist of high or low frequencies. The blocks carriers purchase are located on different sections of the RF spectrum. Smaller bands, on the other hand, are not made up of multiple blocks and are usually exclusive to one carrier. However, they operate on different blocks to avoid interfering with each other. As you'll notice later, many carriers utilize similar bands.

Usually, one license within a large band only gives carriers rights to a small section. Why Do Cellular Carriers Have Multiple Frequencies?Ĭellular carriers need licenses from the FCC to use specific cellular bands. Cellular devices then use those specific frequencies to communicate with carrier cell towers. For example, the 700 MHz frequency band ranges from 699 MHz to 798 MHz.Ĭellular carriers buy multiple frequencies from government airwaves. Cellular frequency bands represent a range of frequencies, not a single cellular frequency. Within the RF spectrum, cellular bands are roughly located between 600 MHz and 39 GHz. They divide it into multiple ranges of frequencies, known as bands. In the United States, the Federal Communications Commission ( FCC) and the National Telecommunications and Information Administration ( NTIA) are in charge of allocating the RF spectrum. They are undetectable by the human ear.Īll cellular frequencies fall under the RF spectrum, which ranges from 3kHz to 300GHz. Cellular frequencies are sound waves cellular devices use to keep you connected. High frequencies mean that the waves move faster, and vice versa. For Commercial What are Cellular Frequency Bands?Ī frequency, measured in Hertz (Hz), is the number of sound waves occurring per second.
