Spectrum Bands of 5G Technology

5G technology utilizes three spectrum bands, which are classified as:

1. Low-band spectrum: Frequencies below 1 GHz, offering broad coverage but slower speeds.
2. Mid-band spectrum: Frequencies between 1 GHz and 6 GHz, providing a balance of speed and coverage.
3. High-band spectrum (mmWave): Frequencies above 24 GHz, which deliver the highest speeds but have limited coverage due to signal attenuation.
