5g 24ghz

Last updated on 

The primary frequency bands for 5G are in the sub-6 GHz range (mid-band and low-band) and millimeter-wave (mmWave) bands, which can include frequencies in the 24 GHz and higher range.

Let's break down the technical details:

5G:

  1. Frequency Bands:
    • Low-Band (Sub-1 GHz): Provides broad coverage but with relatively lower data rates compared to higher frequencies.
    • Mid-Band (1 GHz to 6 GHz): Balances coverage and capacity, offering a mix of data rates and coverage.
    • High-Band / Millimeter Wave (mmWave) (24 GHz and above): Offers extremely high data rates but with shorter range and poorer penetration through obstacles.
  2. mmWave (24 GHz and above):
    • Frequency Range: mmWave bands include frequencies above 24 GHz, typically in the range of 24 GHz to 100 GHz.
    • High Data Rates: mmWave enables very high data rates due to the availability of a wide bandwidth.
    • Short Range: Signals at mmWave frequencies have a shorter range compared to lower frequencies. They are more susceptible to absorption by atmospheric gases and are easily blocked by obstacles.
    • Directional Transmission: Due to higher propagation losses, mmWave systems often use directional antennas to focus the signal.
  3. Technical Challenges:
    • Propagation Loss: Higher frequencies experience higher free-space path loss, meaning the signal weakens more quickly over distance.
    • Obstacle Penetration: mmWave signals have difficulty penetrating obstacles like buildings and foliage.
    • Beamforming: Antenna beamforming is often used to direct signals precisely, compensating for the shorter range.
  4. Applications:
    • Enhanced Mobile Broadband (eMBB): Providing faster data rates for applications like 4K video streaming, augmented reality (AR), and virtual reality (VR).
    • Ultra-Reliable Low Latency Communications (URLLC): Critical for applications requiring low latency, such as autonomous vehicles and industrial automation.
    • Massive Machine Type Communications (mMTC): Supporting a large number of connected devices, as seen in the Internet of Things (IoT).

5G operates across a range of frequency bands, including mmWave bands like 24 GHz and above. The use of these higher frequencies enables very high data rates but comes with challenges related to propagation and coverage, which are addressed through technologies like beamforming and targeted deployment in specific use cases. Please note that the specific frequency allocations and usage can vary by region and network deployment.
