5g range frequency

Last updated on 

The term "5G" refers to the fifth generation of mobile network technology, which promises faster data speeds, lower latency, and greater connectivity than its predecessors. One of the critical aspects of 5G technology is its use of a wider range of frequencies, including both low-band and high-band frequencies, to deliver its promised performance improvements.

5G Frequency Bands:

  1. Low-Band (Sub-1 GHz):
    • Frequency Range: Typically, this includes frequencies below 1 GHz. Specifically, bands like 600 MHz and 700 MHz fall into this category.
    • Characteristics: Low-band frequencies offer better coverage over large areas. They can penetrate buildings and other obstacles more effectively than higher frequencies. However, the data speeds achievable on low-band are not as high as those on higher frequencies.
  2. Mid-Band (1 GHz to 6 GHz):
    • Frequency Range: This encompasses frequencies from 1 GHz up to 6 GHz. Bands like 2.5 GHz, 3.5 GHz, and 4.9 GHz are examples of mid-band frequencies.
    • Characteristics: Mid-band frequencies strike a balance between coverage and speed. They offer higher data speeds than low-band frequencies while still providing reasonably good coverage. These frequencies are crucial for urban and suburban areas where a blend of coverage and speed is required.
  3. High-Band (mmWave, above 24 GHz):
    • Frequency Range: This category includes frequencies above 24 GHz, often referred to as millimeter-wave (mmWave) frequencies. Bands like 28 GHz, 39 GHz, and 60 GHz are part of this range.
    • Characteristics: High-band frequencies offer extremely high data speeds and low latency but come with limited coverage. These frequencies are most suitable for densely populated urban areas due to their limited range and susceptibility to obstructions like buildings and trees. mmWave signals do not propagate as well through obstacles and are more susceptible to atmospheric absorption and signal blockage.

Technical Considerations:

  1. Propagation Characteristics:
    • Low-Band: Better coverage, good penetration through walls and buildings.
    • Mid-Band: Balanced coverage and speed.
    • High-Band: Limited coverage, highly susceptible to obstructions.
  2. Data Speed and Latency:
    • Low-Band: Lower data speeds compared to mid-band and high-band.
    • Mid-Band: Offers higher data speeds than low-band but not as high as mmWave.
    • High-Band: Provides the highest data speeds but has higher susceptibility to environmental obstructions.
  3. Deployment Challenges:
    • Low-Band: Requires fewer base stations due to its better coverage but might face congestion in densely populated areas.
    • Mid-Band: Requires a balance in the number of base stations for coverage and capacity.
    • High-Band: Requires a dense network of small cells due to its limited coverage and susceptibility to obstructions.
