Introduction to Cellular Frequency Bands
Cellular frequency bands are the backbone of mobile communication systems, enabling the transmission of voice, data, and multimedia content. The first generation of mobile networks (1G) operated on analog frequency bands, while subsequent generations (2G, 3G, 4G, and 5G) introduced digital frequency bands with improved capacity and data speeds. The frequency bands are designated by regulatory bodies, such as the International Telecommunication Union (ITU), to ensure efficient use of the radio spectrum and minimize interference between different systems.
Frequency Band Categories
The cellular frequency bands can be broadly categorized into three main groups: low-band, mid-band, and high-band. Low-band frequencies (below 1 GHz) offer better coverage and penetration but are limited by lower data speeds. Mid-band frequencies (1-6 GHz) provide a balance between coverage and capacity, making them suitable for urban and suburban areas. High-band frequencies (above 6 GHz) offer the highest data speeds but are limited by shorter range and higher propagation losses.
| Frequency Band Category | Frequency Range | Characteristics |
|---|---|---|
| Low-band | Below 1 GHz | Better coverage, lower data speeds |
| Mid-band | 1-6 GHz | Balance between coverage and capacity |
| High-band | Above 6 GHz | Higher data speeds, shorter range |
Cellular Frequency Bands Chart

Low-band frequency bands are used for 2G, 3G, and 4G networks, offering better coverage and penetration. The most common low-band frequency bands include GSM-850, GSM-900, and CDMA-800. These bands are widely used for voice and low-speed data applications.
| Low-Band Frequency | Frequency Range | Application |
|---|---|---|
| GSM-850 | 824-849 MHz | 2G, 3G, 4G voice and low-speed data |
| GSM-900 | 880-915 MHz | 2G, 3G, 4G voice and low-speed data |
| CDMA-800 | 806-824 MHz | 2G, 3G, 4G voice and low-speed data |
Mid-Band Frequency Bands
Mid-band frequency bands are used for 3G, 4G, and 5G networks, offering a balance between coverage and capacity. The most common mid-band frequency bands include UMTS-2100, LTE-1800, and LTE-2500. These bands are widely used for high-speed data applications, such as mobile broadband and streaming services.
| Mid-Band Frequency | Frequency Range | Application |
|---|---|---|
| UMTS-2100 | 1920-1980 MHz | 3G, 4G high-speed data |
