5g supported bands

Last updated on 

The 5th generation of mobile networks, commonly known as 5G, operates on a variety of frequency bands. These frequency bands are allocated by regulatory bodies and vary across different regions and countries. Each band has its own characteristics, advantages, and limitations. Here's a technical explanation of some of the key 5G frequency bands:

  1. Sub-1 GHz Bands (Low-Band or Sub-6 GHz):
    • Frequency Range: Typically below 1 GHz (e.g., 600 MHz, 700 MHz)
    • Characteristics: These bands offer wide coverage and good penetration through buildings. However, the data rates are not as high as in higher frequency bands.
    • Use Case: Provides the foundation for extensive coverage in urban and rural areas.
  2. Mid-Band (2-6 GHz):
    • Frequency Range: Includes frequencies between 2 GHz and 6 GHz (e.g., 3.5 GHz, 4.9 GHz)
    • Characteristics: Balances coverage and data rates, offering a good compromise between the low and high bands. Offers a moderate level of coverage and data speed.
    • Use Case: Suitable for urban and suburban areas where a balance between coverage and capacity is required.
  3. mmWave (Millimeter Wave) Bands (24 GHz and above):
    • Frequency Range: Typically above 24 GHz (e.g., 28 GHz, 39 GHz)
    • Characteristics: These bands offer extremely high data rates but have limited coverage and are susceptible to blockage by obstacles such as buildings and trees.
    • Use Case: Ideal for high-density urban areas and venues where very high data rates are required.
  4. Unlicensed Spectrum (e.g., 5.9 GHz, 60 GHz):
    • Frequency Range: Various frequencies in unlicensed bands
    • Characteristics: Utilizes spectrum not exclusively licensed for mobile communications. Can be used for localized, high-capacity applications.
    • Use Case: Augments licensed spectrum in specific scenarios, such as dense urban environments.
  5. Dynamic Spectrum Sharing (DSS):
    • Description: DSS allows for the sharing of spectrum between 4G LTE and 5G technologies. It enables a smoother transition to 5G by dynamically allocating spectrum resources based on demand.
    • Use Case: Allows for the coexistence of 4G and 5G networks in the same frequency band.
  6. Carrier Aggregation:
    • Description: Carrier aggregation involves combining multiple frequency bands to increase data rates and overall capacity. This can be applied to both 4G and 5G networks.
    • Use Case: Enhances network capacity and data speeds by aggregating multiple frequency bands.

It's important to note that the specific frequency bands used for 5G can vary between different countries and regions due to regulatory decisions and the availability of spectrum. Additionally, some bands may be repurposed or expanded over time to meet the evolving needs of 5G networks.
