5g hertz range

Last updated on 


The 5G technology brings with it a range of frequency bands, each with its own characteristics in terms of bandwidth, propagation characteristics, and deployment scenarios. The hertz (Hz) range refers to the frequency at which electromagnetic waves propagate, and in the context of 5G, different frequency bands offer varying trade-offs between coverage and data-carrying capacity.

Let's break down the 5G hertz range:

  1. Sub-1 GHz (Low Band) Frequency Range:
    • Frequency Range: Typically refers to the 600 MHz, 700 MHz, and sometimes 850 MHz bands.
    • Characteristics: These lower frequencies provide excellent coverage over large areas. They can penetrate buildings and other obstacles relatively well. However, the data-carrying capacity is limited compared to higher frequencies.
    • Use Case: Ideal for rural areas or areas where providing wide coverage is more critical than extremely high data speeds.
  2. 1 GHz - 6 GHz (Mid Band) Frequency Range:
    • Frequency Range: Covers bands like 2.5 GHz, 3.5 GHz, and others up to 6 GHz.
    • Characteristics: This mid-band spectrum offers a balance between coverage and capacity. It provides faster data speeds than the low band but still offers reasonable coverage. The propagation characteristics are a mix between low and high bands.
    • Use Case: Suitable for urban and suburban areas where a balance between coverage and capacity is essential. This band is crucial for many initial 5G deployments due to its balance between speed and coverage.
  3. Above 6 GHz (High Band or mmWave):
    • Frequency Range: Includes bands like 24 GHz, 28 GHz, 39 GHz, and beyond.
    • Characteristics: These extremely high frequencies offer massive data-carrying capacity, enabling multi-gigabit-per-second data speeds. However, they have a limited range and are susceptible to blockages by buildings, trees, and even rain.
    • Use Case: Best suited for dense urban areas and specific use cases like stadiums, airports, or areas where there's a high demand for bandwidth. Due to their limited range, deploying them requires a dense network of small cells.

Technical Considerations:

  1. Propagation Characteristics: Lower frequencies (sub-1 GHz) propagate further and penetrate obstacles better. Higher frequencies (above 6 GHz) have limited range and can be easily obstructed.
  2. Bandwidth and Speed: Higher frequency bands (especially mmWave) offer wider bandwidths, enabling faster data speeds. The broader the bandwidth, the more data can be transmitted simultaneously.
  3. Infrastructure Requirements: Deploying 5G across different frequency bands requires different infrastructure considerations. For example, mmWave deployments need a denser network of small cells due to their limited range, while lower bands might leverage existing infrastructure more effectively.
  4. Device Compatibility: Not all devices support all frequency bands. Manufacturers need to design devices that can operate across the various 5G frequency ranges to ensure consistent service.
